Preparing for the Future Australian Army Chief of Staff opened the recent Land Warfare conference and exhibition to discuss how he is fighting the present war and preparing for the next. By Lieutenant General K.J. Gillespie AO DSC CSM For too long, Army has accepted a narrow, project- and platform-based approach to modernization and I am very keen to progress the cooperation currently being demonstrated between Army, Capability Development Group and the Defence Materiel Organisation to ensure that our projects are delivered as capabilities and within budget guidelines. Army has lifted its game of late to adopt a more effects- and systems-based method of identifying and introducing land-force capabilities. These days, Army manages systems, not projects. I believe the structural and cultural changes we have made as part of my Adaptive Army initiative have made us a more discerning and perhaps more demanding customer. This is certainly in our interests and, I hope you agree, also in yours. I want to provide you with context on the underlying strategic rationale for Army modernization. In particular, I want to share my thoughts as to how the Army is seeking to tackle the permanent dilemma constituted by the demands of sustaining high tempo in our operations, while introducing new capabilities and building our approved future force. The recurring tension between fighting ‘the war’ while planning for ‘a war’ is familiar to all professional soldiers—and we need industry involved at key points along the continuum of interaction between the Defence Materiel Organisation, the Capability Development Group and me, as the capability manager. As I mentioned, this issue is making enormous demands even on an Army the size of our U.S. allies. Vice Chief of Staff of the US Army General Peter Chiarelli
informed me during the exercise this week of measures being implemented to purchase the best available equipment, more frequently, in lesser quantities, in order to capitalize and keep pace with rapid technological advancement. We now refer to this approach as adaptive acquisition. He also spoke of the need to develop survivable, robust and self-healing communication networks which can move information across armies and across coalitions. My assessment is that, on many of these issues, the difference between our situation and that of the US Army is a question of scale rather than substance. The nature of the problem will be familiar to all of you. You encounter it in your businesses every day. In essence, it is the tension between conducting current activities at the level of excellence required to achieve the mission and protect soldier’s lives, while maintaining a weather eye on the medium-term and longer-term future. Of necessity, this involves a process of balancing between current and future investment, and current expenditure, while simultaneously implementing continual adaptation to stay aligned with changes in the operating environment. The key elements of this dilemma as it confronts me as Chief of Army are as follows: I need to raise, train and sustain ready and relevant land forces for diverse simultaneous operations today in Afghanistan, Timor Leste, the Solomon Islands and a variety of smaller missions, while building, at the same time, an Army capable of meeting the full spectrum of threats well into the future. The definitive guidance as to the composition of that future
www.defense-house.com
is detailed for us in the 2009 Defence White Paper, and the Government has indicated the broad fiscal strategy to provide the force structure required by their strategic guidance. Overlaying all of this is the demand from the government that Defence find internal savings in order to fully fund projects forecast in the Defence Capability Plan. Under the banner of the Strategic Reform Program, the Australian Defence Organisation must find savings of $20 billion over the next 10 years. Our budgetary environment for the immediate future will almost certainly remain a zerosum game. The savings required from the Strategic Reform Programme necessitate deep organizational reform. I am pleased to say that our early work across all levels of command within Army, and in cooperation with other groups in Defence, is making real progress in unlocking these savings. The War Now, a few points about the war: We are currently involved in demanding operations against a very determined and adaptable enemy in southern Afghanistan. In our recent parliamentary debate, the government reaffirmed that our country is likely to be committed to this theater for some time to come. Although Army is providing the bulk of the forces in Afghanistan, that operation—like all of
Emerging Defense Technologies
4 our deployments—is inherently joint. I am completely candid with you in saying that Army simply could not sustain our ongoing commitments in Afghanistan and other theatres without the assistance of Navy and Air Force. And when I refer to Army, I mean our full- and part-time components. Our Reserves are vital to my sustainment campaign plan. Indeed, all of our operations are becoming increasingly multi-agency, incorporating what our allies call the comprehensive approach. In Afghanistan, our forces are simultaneously supporting a coalition counter-insurgency strategy while raising, training and mentoring the Afghan National Army 4th Brigade so that it is capable of providing security in Uruzgan Province after the coalition forces finally withdraw. That is the war. However, we cannot be so preoccupied with current operations that we become oblivious to our changing strategic environment. Nor can we neglect the longer-term thinking and investment that is required to ensure that the Army can meet the objectives required of it by the White Paper as well as provide the foundations of the Army of the second half of this century. We need to avoid the risk of tailoring our forces specifically to meet the demands of our current conflict. I am determined to maintain and improve our foundation warfighting skills, particularly in the employment of combined arms in a conventional setting. This task is clearly
outlined in our strategic guidance, and it requires us to be able to act decisively in defense of Australia’s national interests. I do not share the view of some analysts that hybrid and irregular war will define the future. The risk of conventional war between states is enduring and the government demands that we can deliver land forces capable of this level of combat. That is, it insists that the Army be capable of fighting a war—the characteristics of which may be vaguely discernible to us in 2010. But we can be certain that it will be characterized by high levels of violence and lethality and the use of networked systems of sensors and shooters. My principle task as Chief of Army is as a force generator—to generate sustainable force elements that are prepared to undertake the operations government requires of us today, and to ensure that we train, equip, adapt and adjust our structures to generate the forces that may be required in the future. My business is force generation. By the time I became chief in 2008, I was determined to review the manner in which Army was conducting our force generation. I was also convinced that our structures could be better aligned to the new ADF Joint Operational Command arrangements that had evolved in the later part of last century and the early part of this decade in response to the escalating operational tempo that commenced with Interfet. Those concerns provided the impulse for the significant structural and cultural reform that I have instituted as Chief of Army.
January 2011
While we have always run an excellent individual training system, I believed that our collective training left a good deal to be desired. I could also see no rational reason to have two separate functional commands (Training Command and Land Command) delivering different elements of what should be a seamless individual and collective training process. Moreover, our stove-piped structures were inhibiting the rapid capture and dissemination of lessons from operations back through our force generation system. In peacetime, we got away with it. But for an Army at war, we ran the risk of failure. Of course, it is absolutely right that we focus an enormous amount of our efforts into supporting our soldiers in the current fight. The Deputy Chief of the Army Major General Paul Symon maintains the Army Sustainment Campaign Plan—a living and constantly evolving document which monitors and reviews pressures on Army personnel and equipment that might present varying degrees of risk to the sustainment of our current operations. Once identified, these risks can be treated with amendments to force generation priorities, rapid acquisition of essential equipment or through a modification to force design in theatre to provide more sustainable force structures. Under the Adaptive Army reforms, we are continuing to refine the processes for the optimal generation and preparation of our force elements. During my regular tours of our operational areas and units in training, I have been very encouraged to witness, first hand, just how quickly our forces are showing the benefits of a more structured and deliberate approach to preparing for operations. Force Generation
Emerging Defense Technologies
Let me talk firstly about the changes we have made to our force generation—the purview of our forces commander. The establishment of Forces Command, under the leadership of Major General David Morrison, enabled Army to bring under a single unified command, the responsibility for individual and collective training— from our recruit and initial employment courses through to the highest standards of collective training short of mission-specific training and mission-rehearsal exercises. We call this our foundation warfighting skills—the skills needed for ‘a war’ rather than ‘the war’.
www.defense-house.com
January 2011 This single unified command structure also enables Army to weight our effort and resources to support specific training objectives at a given time of the year. This in turn has resulted in considerable cost savings compared to the training undertaken in our pre-Adaptive Army structures. These significant benefits and efficiencies associated with the formation of Forces Command were demonstrated recently on Exercise Hamel in north Queensland. Exercise Hamel was largely a freeplay, intelligence-led activity designed to test the 3rd Brigade, augmented with significant combat support and combat service support assets, in the full spectrum of operations. Consistent with our contemporary operations ‘amongst the people’, the exercise included many diverse population groups and was designed to test Army’s ability to fight and defeat a near peer and technologically adept adversary. It involved more than 6,500 soldiers and has set a new benchmark for how we instill in our soldiers the skills and knowledge to prosecute conventional operations. There were activities on this exercise that I witnessed that I had not seen conducted in my 40-plus years of service. Moreover, such are the efficiencies generated from the structural changes in Adaptive Army, the exercise was funded for under $20 million, without the requirement for me to give a single cent to the forces commander on top of his already-approved budget. Our force-generation cycle also allows us to plan with greater certainty, and more realistic lead times, the introduction into service of new capabilities and equipment
5 as we move steadily towards our approved future force. In a few short years, we will accept into service: new amphibious ships giving Australia a true amphibious capability; we are replacing our entire B-vehicle fleet and developing a new combined-arms fighting system. We will introduce new artillery systems; bring into service new helicopters and watercraft; and roll out capabilities to enhance battlefield digitization. Many of you in the audience will be involved in the procurement of this equipment. But it’s vital from Army’s perspective that we prepare and conduct comprehensive trials and introductioninto-service plans so that we can continue to modernize our force, without detriment to the sustainment of our considerable operational tempo. This is my principle challenge. A deliberate and structured force-generation cycle, with clearer and more pragmatic requirements definition, under a unified command-and-control structure, gives us the means to meet both these ends. Force Preparation We have also made real progress in the past 12 months in our force preparation, mission-rehearsal exercises and operational certification—the planned, deliberate training we undertake to provide our forces the specific skills and knowledge they require for a particular operation— or the war. Headquarters 1st Division, commanded by Major General Mick Slater, has responsibility for this key task, and
www.defense-house.com
exercises these responsibilities primarily through an organization called the Land Combat Readiness Centre. The Land Combat Readiness Centre takes soldiers through realistic, scenariobased training prior to deployment. Its adaptive warfare cell is responsible for capitalizing on the latest operational lessons and insights, and ensuring that they are formally incorporated into the very next exercise package for the next deploying force—this is what we refer to as our immediate- and short-term learning loops. I have also ensured that our Army Headquarters Battleboards have representation from operational theaters through video-conference facilities, when they are discussing rapid acquisition capability-development issues. These formal learning processes are essential to ensuring our soldiers are able to stay one step ahead of a lethal and rapidly evolving enemy. The advantages afforded by this formal, force-preparation structure are many. First, we are able to deliver the most comprehensive and realistic training possible, informed by recent events and operational reporting from overseas, prior to our deployments. The training, facilities and simulation our soldiers utilize to prepare for operations have become world class. Second, it enables me to see, through a formal certification process, what shortfalls a particular force element may need to address before they move into a specific area of operations. These shortfalls are formally reported and addressed in either further training in Australia or
Emerging Defense Technologies
6 during final in-theatre training before the commencement of operations. And finally, it provides a comprehensive auditable trail of what training our force elements have undertaken before they are force assigned. We also follow a similar process when soldiers dismount from operations and undertake post-operational administration and decompression before returning to their parent units. One of the key, albeit less tangible benefits that these recent changes herald, is that our people will now be better able to see more clearly the quality of their training. In turn, such clarity will instill in them greater confidence when they eventually reach their operational destinations. Their confidence in the training and in the other people they work with is, I think, an essential aspect to strengthening a soldier’s capacity to be more agile in their ‘thinking’ and ‘doing’ in the face of the enemy. What I appreciate most about the changes we have made to our force preparation systems is that they now recognize that Army’s IQ does not reside solely with me and Army’s senior leadership. The answers to many of the problems we face today lie in the collective knowledge of all of Army’s soldiers and officers. And we’re looking for more and more ways to harness this collective knowledge. So, our force preparation can now be informed and improved by a sectioncommander’s ideas from Tarin Kot, by a soldiers’ suggestion from an after-action review in a mission-rehearsal exercise and from post-operational reports from a unit recently returned from operations. The ability to harness and capitalise on the collective knowledge of the whole force is the key to remaining adaptive against the full spectrum of threats. A More Demanding Customer Another idea in which we’re seeking to become more agile and flexible is in the procurement of certain items of combat equipment. The structural changes we have made in Army Headquarters, under Adaptive Army, mean that, for the first time, Army has a staff division, headed by Major General John Caligari, Head of Modernisation and Strategic Planning in Army Headquarters, which is dedicated to looking forward and thinking about Army’s future. This means that we are in a far better position to be able to articulate our requirements and engage effectively
Emerging Defense Technologies
with the Defence Materiel Organisation, Capability Development Group and industry. This is certainly a positive for Army, and I hope that representatives from these organizations who are in the audience feel the same way. Having this additional staff support at hand means that Army is better able to support the information requirements of any organization involved in developing or modernizing Army capability. An example of Army’s new focus on capability risk, as opposed to project risk, is the recent discussions we’ve been having with our partners about a system of adaptive acquisition—that is, buying smaller quantities of equipment in more frequent iterations to ensure that the latest technological developments and advancements can be more rapidly provided to our soldiers as they strive to achieve their missions. This system has particular utility for equipment that has an expected life, as a consequence of wear and tear or technological advancements, of less than five years. We certainly had some success in developing new ammunition pouches in this fashion in our latest deployment cycle and plan on providing better body armor in the same fashion during the next deployment cycle. I’m very grateful for the support I am receiving for this new approach from Steve Gumley and his organization and I am determined that, together, we can continue to expand this program. More to be Done… I hope, in outlining the changes we’ve made to our force-generation and forcepreparation procedures that you can see Army is well on the path to inculcating, in a systematic fashion, adaptive responses to
January 2011
complex environments. But there is much, much more to be done. We have begun an annual review of our force structures and dispositions in Australia to ensure we are best positioned to remain within government fiscal guidance while sustaining an operational tempo which shows no signs of diminishing in the near future. This review updates our Army Objective Force and considers a wide range of factors including white paper guidance, futures concepts, threat forecasts, and deployment/respite ratios in determining the optimal force lay-down for Army in Australia. The first iteration of the Army Objective Force Handbook will be discussed at my senior advisory committee next month and endorsed as the start of Army’s journey towards Force Structure Review 2013. The work to implement this plan is one step behind and is known now in Army as Plan Beersheeba. By mid next year, I hope to have completed the review and be in a position to brief government on what changes to Army structure they might consider. I also see a real need to keep our industry partners engaged as we continue to adapt to our changing environment. For example, I believe 3 and 4G technologies offer real potential in developing our future combat communications systems. Do we need to persist with a system of vehiclebased radio stacks for communications or is it possible to move to an encryptionenabled I-phone system of applications to give our commanders all the information they need at the touch of an icon? How can I continue to harness the IQ of our organization as I alluded to earlier when less that 45 per cent of Army has regular access to the Defence Restricted Network, our most widely used IT system?
www.defense-house.com
January 2011 With more than 70,000 fans on Army’s Facebook page, I wonder whether such social networking sites offer us greater utility in communicating more regularly with our people and their families. Moreover, how much more efficient would our workplace become if all of our soldiers had access to the Defence Restricted Network (at work or remotely from home) to handle their own leave administration, pay and individual recall and notification records. We also need to constantly monitor and review the delivery of our key capabilities as we enter this significant period of modernization. As the landcombat capability advisor, I see these projects as warfighting capabilities and it’s important that Army moves to take more responsibility for modernization outcomes as these key platforms come into service. Our Defence Force must also continue to invest time, resources and human capital in growing our cyber- and spacerelated capabilities. This will impact upon Army’s capability in a way we’re yet to fully conceive. Yet an Adaptive Army should know implicitly where and how
7 technological advancements will afford it advantage on the battlefield, and where it will not. Industry has demonstrated commendable agility in helping us with rapid development and acquisitions as we have identified urgent capability requirements whilst ‘in contact’ with the enemy. I look forward to working alongside you in developing similar responsiveness as we attempt to move towards a more responsive and adaptive acquisition strategy. Conclusion So, there are clearly some real challenges ahead, including a tightly constrained fiscal environment. With the progress we have already made under the Strategic Reform Program, Army is well on the way to unlocking savings such that we can reinvest in vital high-priority, high-end capabilities earmarked by the government’s latest white paper. I have briefly highlighted the mechanisms we have implemented to move Army onto a permanent adaptive footing in
www.defense-house.com
our force generation and force preparation. No less challenging is preparing the Adaptive Army to operate with and among new and emerging technologies. Improving the sensor/shooter interface, enhancing distributed information-sharing systems, and using new web-based applications to rapidly communicate, retain and share knowledge, are but a few of the innumerable commercial and military technology innovations that we must understand and, where feasible, utilize. Army is taking greater control of its own modernization and is finding a great deal of support from all quarters to change the way we acquire capabilities in order to better support our people. We have a long way to go. We can achieve none of this ambitious agenda without defense-industry support. Events such as this conference serve to reinforce the vital need for that partnership and also to help us share the latest insights and perspectives you may have. I am very grateful for the tremendous support that all of you have given to the Australian Army through your involvement in this conference. I am delighted to declare the 2010 Land Warfare Conference open.

Analysis of Soldier Effectivenes in an MRAP This article is based on a paper presented at the NDIA Ground Systems Engineering and Technology Symposium and presents modeling methodology and results for a study of Soldier effectiveness in a hot environment. The effectiveness of soldiers is diminished under conditions of high heat stress. Excessive heat stress will degrade mental and physical performance capabilities and eventually cause heat casualties.The core temperature of a human body provides the “best� single physiological measure to estimate physical work capabilities during hot weather operations. Prediction of Soldier effectiveness in extreme environments can be accomplished through the use of segmental human thermoregulation models. Differences in physiological characteristics among soldiers can affect thermoregulatory response and must be accounted for when predicting effectiveness. Additionally, prediction accuracy can be improved by combining human thermoregulatory models with a complete characterization of the thermal environment. Human thermal models representing Soldiers with significant physiological differences among them were placed into a full-vehicle thermal HVAC predictive model of a mine resistant ambush protected (MRAP) vehicle.The simulation was performed to support US Army PMMRAP in its effort to improve Soldier effectiveness under conditions typically encountered on MRAP vehicles fielded in Iraq.

January 2011 Excessive heat stress can degrade the mental and physical performance capabilities of soldiers to the point that it can eventually result in heat casualties. Given that heat stress is defined as “environmental and host conditions that tend to increase body temperature” [1], the core temperature of a human body provides the “best” single physiological measure to estimate physical work capabilities during hot weather operations. Fortunately, soldier effectiveness in extreme environments can be accurately predicted through the use of segmental thermoregulation models [2, 3]. These sophisticated thermal models of the human body are able to react to transient and asymmetric boundary conditions by simulating changes in blood flow, metabolic heating and sweat evaporation at the skin surface. Differences in physiological characteristics among soldiers can
9 also be accounted for since these may affect thermoregulatory response and subsequently provide a more accurate prediction of effectiveness. Heat stress can result from a combination of environmental and mission risk factors. Environmental risk factors consist of air and surrounding temperatures, air speed, humidity, and solar irradiation. Mission risk factors consist of activity level, clothing, and length of heat exposure. In light of this, prediction accuracy can be improved by combining complete characterizations of human thermoregulatory models with those of the surroundings (e.g. vehicle, building). Such coupled simulations allow the temperatures and heat rates of both the thermoregulatory models and the surroundings to be solved for simultaneously.

Methodology A utility was developed to automate the process for building a physiological description of a non-standard (i.e., not 50th percentile) body build. Only the target body size (expressed as a percentile of the population) and the physiological description of a ‘standard man’ are required as inputs. The physiological description consists largely of a list of segments, tissues and the properties associated with them, such as segment lengths and tissue radii, thermal properties (e.g basal metabolic and blood perfusion rates, conductivity, density, specific heat, etc.), sensitivity coefficients and active thermoregulation distribution coefficients.

The utility automatically adjusts the passive system parameters of the baseline physiology [2] in proportion to known deviations from overall weight, height, and individual segment lengths of the 50th percentile male by assuming a Gaussian distribution ranging from the 1st percentile to 99th percentile and centered at the mean (50th percentile) [4]. Once a physiological description can be established, it can be applied directly to a shell-element representation of the human geometry for use by a thermal solver. Since the geometry will be automatically scaled to match the physiology upon the start of the thermal solution, it is not necessary that the geometry size and dimensions match the physiological description.
surface area (Aactual =2.20m2, AD =2.27 m2) deviated from its target value by only 4%. Model Setup Seven unique human thermal models representing Soldiers with a variety of body builds ranging from the 5th percentile to the 95th percentile were placed into a full-vehicle thermal HVAC predictive model of a Mine Resistant Ambush Protected (MRAP) vehicle. The geometry of each Soldier was customized to have a different body size and pose. Figure 1 shows the Soldier geometry with body size labels for each. All seven Soldiers were dressed in a t-shirt, briefs, desert BDU shirt and pants, and socks and shoes.
Building Physiologies From the desired body build specification and the physiological description of the standard man, the wholebody height and weight can be obtained from established anthropometric data [4]. The body fat mass (kg) for the individual can be calculated based on the following correlation valid for males of normal build [5]:
BF male = 0.685W − 5 .86 H 3 + 0 .42
(1)
The fat layer in each body segment can then be adjusted by applying a single fat adjustment factor to each fat layer in the model -- obtained by dividing the target whole body fat mass by the baseline physiology’s fat mass. Since the underlying physiological description defines tissue content for each segment by an outer tissue radius, rather than by mass, the fat layer radii were adjusted as necessary while updating the segment-level skin radii to maintain required skin thickness. Applying a similar technique to obtain the corresponding whole body weight for the desired percentile, the masses of all of the tissue layers residing under the fat layer in each segment were adjusted, until the target whole-body mass was reached. Validation of the overall technique was performed by comparing the actual whole body surface area of the resulting physiology, defined by the outer radii and lengths of each segment, with the Dubois surface area, AD, obtained from the target percentile’s height and weight.
AD = 0 .202W 0.425 H 0.725
(2)
Since the focus of this project was military in nature, the upper 5% and lower 5% of percentiles were excluded from this study in accordance with the military’s intent to accommodate no more than 90% of the general population. At the lower extreme, the 5th percentile male’s surface area (Aactual =1.49m2, AD=1.59 m2) was within 7% of its predicted value while at the upper end, the 95th percentile male’s
Figure 1: Soldier geometry labeled with body size Table 1 presents the high-level body size descriptions of the Soldiers, as well as their corresponding boundary conditions. Each Soldier was modeled with an activity level of 1.2 met, which correlates to a seated but slightly active physical state. The air velocities near each Soldier were approximated from previously obtained CFD results of the vehicle interior, while the local air temperatures were calculated automatically during the solution using a sub-volume air flow and heat transfer modeling technique [6].

All of the Soldiers experience a thermal sensation spike when they first enter the hot vehicle. Their sensation then slowly decreases towards neutral as the vehicle cools down. Figure 9 illustrates that the Soldiers experience discomfort due to the hot environment present early in the cool down; however, their comfort improves as the air and surface temperatures drop inside of the vehicle. Also, as evidenced in the plots of core and skin temperature, the driver (50th percentile Soldier) is the hottest and least comfortable person at the beginning of the simulation.

CONCLUSION The effectiveness of Soldiers with varying physiological builds was examined by simulating their thermoregulatory response when placed in an MRAP vehicle experiencing a transient cool down after an initial hot soak. Although the thermal sensation and comfort results indicate that actual Soldiers would feel hot and uncomfortable for a significant amount of time after first entering the vehicle environment being modeled, the core temperature results show that Soldier effectiveness would not be adversely affected. Furthermore, since a wide range of physiological builds were accounted for in this simulation, it can be expected that the environment

A vehicle which can “sweat” to improve stealth is among hundreds of ideas presented to the UK Ministry of Defence from a BAE Systems study designed to show them the future.
Emerging Defense Technologies
The UK Future Protected Vehicle program aims to highlight both short and long-term technologies and concepts which can be used to boost the effectiveness of lightweight armored vehicles. The numbers give an idea of the scale of the program: 567 technologies and 244 vehicle concepts were investigated following engagement with 35 organizations. From this array of concepts, the team subsequently developed seven concept vehicles, each highlighting technologies which
could support a particular specialization. No fewer than 47 of the technologies were highlighted as being suitable for immediate pursuit. The BAE Systems team made a point of gathering ideas from as wide a spectrum as possible, including academe and industry. A series of panels identified ideas for further study, funded out of the £2 million DSTL (Defence Science and Technology Laboratory) contract. The team even engaged Shanklea

Its land strategy lead John Hunt commented: “I was very impressed by the work. Not just by the outputs, but also the inclusivity with which the study was carried out and the robust systems engineering methodology underpinning it.” “The quick-wins element was particularly pleasing as support to current operations is vital,” Hunt added. Hisham Awad, who works on emerging technologies for BAE System’s Vehicles business, commented: “BAE Systems has signaled intent for future armored vehicles programs by bidding and winning the research contracts that enable bright ideas to become new innovative and highly capable vehicles.” The team already has a contract extension to do further work and will bid for the next phase virtual prototyping work.

Sweating vehicle could use water from a diesel or fuel cell propulsion system to reduce a vehicle’s thermal signature by “sweating” it out through pores in the vehicle skin. That same water could also be reclaimed to enable soldiers to stay in the field for longer. eCamouflage will allow a vehicle to match its camouflage to its surroundings by using electronic ink - rather like a squid. Integrated biometrics will ease
the workload on soldiers in complex crowd situation such as roadblocks and riots by running video surveillance through facial recognition and behavior modeling software to spot potential troublemakers. Active protection will intercept incoming fire or disrupt targeting mechanisms while actuated spaced armor will allow a vehicle to deploy in compact mode before extending its armor to provide increased stand-off distance. A version of this is envisaged as employing electromagnetic magnets to “float” above a vehicle to provide protection from aerial threats.

HMMWV Live Fire Testing The DoD’s Inspector General office recently looked at the live fire testing of light tactical wheeled vehicles and determined that it was effective for the portions completed. The Inspector General’s objectives were to determine whether the Army effectively planned, executed, and evaluated High Mobility Multi-Purpose Wheeled Vehicle (HMMWV) live fire testing and whether DoD exercised adequate live fire test and evaluation (LFT&E) oversight of the Army’s HMMWV Program. Background This is the second in a series of reports on the Army’s efforts to develop, test, and acquire armor solutions for light tactical wheeled vehicles. The first report in the series, DoD Inspector General (IG) Report No. D-2010-039, “Recapitalization and Acquisition of Light Tactical Wheeled Vehicles,” January 29, 2010, addressed the Army’s efforts to develop and acquire the
risk reduction vehicle, or XM1166, and the next generation expanded capacity vehicle, or ECV2. They initiated these audits as a result of information gathered while conducting the audit that led to DoD IG Report No. D-2009-030, “Marine Corps Implementation of the Urgent Universal Needs Process for Mine Resistant Ambush Protected Vehicles,” December 8, 2008. Specifically, they were presented with information that led them to question the survivability testing of the HMMWV against mines and improvised explosive devices (IEDs). Live Fire Test and Evaluation LFT&E is a test process to evaluate the vulnerability and lethality of a conventional weapon or a conventional weapon system.
LFT&E provides insights into a weapon system’s ability to continue to operate or fight after being hit by enemy threat systems. Live fire testing provides a way to examine the damage inflicted on materiel and personnel and an opportunity to assess the effects of complex environments that crews are likely to encounter in combat. Conducting live fire tests is very complex, and many factors have to be considered in the LFT&E of tactical wheeled vehicles. Those factors include, but are not limited to: the type of munition used, standoff distance of the vehicle to the explosive, projectile orientation angle, shotlines, the size of the fragmentsimulating projectile (FSP), where to fire FSPs at the vehicle, soil conditions, whether to conduct a test that would cause catastrophic or significant damage to the vehicle, and differences between the individual vehicles. (An FSP is a specific fragment simulator type based on a standardized cylindrical projectile with a chiseled nose. It is designed to be fired from a gun to simplify armor testing.) Test Methodology Concerns During the audits of the “Marine Corps Implementation of the Urgent Universal Needs Process for Mine Resistant Ambush Protected Vehicles” and “Recapitalization and Acquisition of Light Tactical Wheeled Vehicles,” the Inspector General’s office interviewed vehicle survivability subject matter experts who expressed concerns about the U.S. Army Test and Evaluation Command’s (ATEC’s) live fire testing methods. Specifically, the subject matter experts were concerned that ATEC personnel: •

Emerging Defense Technologies
18 vehicle armor protection in soil that did not represent the soil found in theater operations. Results To address the vehicle survivability subject matter experts’ concerns about ATEC’s live fire testing methods, the IG reviewed ATEC’s LFT&E planning and execution, use of FSPs, use of C-4 in lieu of TNT, and whether the soil used in live fire testing was representative of the soil found in theater operations. The IG also evaluated Director, Operational Test and Evaluation’s (DOT&E’s) LFT&E oversight of the HMMWV Program. Planning and Execution of Up-Armored HMMWV Live Fire Test and Evaluation was Effective for the Portions Completed ATEC’s live fire testing of the up-armored HMMWV was effective for the portions completed. Specifically, ATEC planned a live fire test strategy for the HMMWV Program that identified required documents needed to determine system and crew survivability. ATEC provided the required live planning documents to the Office of the DOT&E for approval and ATEC executed tests in accordance with the approved live fire test plans. ATEC has not yet completed the uparmored HMMWV LFT&E report but will provide it, upon completion, for DOT&E’s evaluation of the up-armored HMMWV LFT&E. Fragment-Simulating Projectiles Data collected by the U.S Army Aberdeen Test Center and the U.S. Army Research Laboratory (ARL) revealed that the tactic of employing artillery shells as surface-laid IEDs, as opposed to an airburst detonation, resulted in an increase in the number of the bigger fragments threatening a vehicle. An ARL representative stated that the 20 mm FSP represents the 97th percentile of fragments, by mass, from a surface-laid 152 mm artillery shell detonation. Based on ARL’s test data, the IG confirmed that the 20 mm FSP represents the 97th percentile of fragments, by mass, from a surface-laid 152 mm artillery shell detonation. The Army used a combination of FSP tests, full-up system level vulnerability tests, and modeling and simulation to determine the up-armored HMMWV’s capabilities and limitations against surface-laid artillery shellbased IED threats and other threats.
Emerging Defense Technologies
Full-up system level vulnerability tests are tests conducted on a complete system loaded or equipped with all the dangerous materials that normally would be on board in combat (including flammables and explosives) and with all critical subsystems operating that could make a difference in determining the test outcome. These tests use munitions likely to be encountered in combat. Explosive Equivalency An ATEC representative stated that, from May 2004 to November 2006, ATEC used the C-4 explosive conversion as a substitute for a TNT mine explosive when performing underbody tests of the HMMWV variants. ATEC used C-4 to support the HMMWV requirement to provide underbody protection against mine blasts to the HMMWV variants. The C-4 conversion used by ATEC created smaller sized craters during the test events than the crater sizes created by TNT mines in theater. ATEC representatives stated that they used the C-4 explosive substitute because it was the best they could do at the time. Although ATEC incorrectly used C-4 as an explosive equivalent to TNT when performing underbody mine testing, the TNT mine weight requirement in the September 2004 HMMWV operational requirements document was less than two-thirds of the mine explosive weight experienced in theater operations. By 2008, ATEC changed the testing methodology from using the C-4 explosive equivalent as a substitute for the TNT underbody mine threat to using a cast TNT mine. ARL developed cast TNT mines as threat surrogates for the actual mine. As documented in its live fire test planning documents, ATEC plans to use an approved threat surrogate during live fire testing instead of the C-4 explosive conversion in its underbody mine blast testing. Soil Testing An ARL representative stated that he discussed with officials from Developmental Test Command the possibility of conducting a study to determine whether test procedures in a new soil would be repeatable. He stated that ARL can complete this type of study. Further, the representative stated that current tests conducted in consistent soil retain a 10 to 25 percent variability in blast effect from shot to shot. ARL is also in the process of developing a comparison of the different types of soil
January 2011
that range from dense, saturated clay to loose, sifted sand. From this comparison study, ARL is working on a rough conversion factor that would allow testers to take real observed test results done in one soil condition and use that data to estimate probable results of the same test as if it had been done in another soil type. Results of tests would still need to be compared to older vehicle tests done in the current standard test soil. A representative from the U.S. Army Corps of Engineers Engineer Research Development Center provided a 2009 report which examined the detonation of explosives in soil. He also stated that the Center is in the process of conducting a soil study that will focus on the tactical implications of differences in soil conditions. The study will identify how soil conditions affect ground radar used in IED detection systems and how the depth of an IED affected the blast to vehicle underbellies. The U.S. Army Corps of Engineers Engineer Research Development Center surveyed 10 to 11 sites, and the United Kingdom team members are gathering data from five additional sites. Effective Oversight by the Director, Operational Test and Evaluation Oversight The Office of the DOT&E’s LFT&E oversight of the Army’s up-armored HMMWV was effective for the portions of the oversight process completed. The up-armored HMMWV was added to the Office of the Secretary of Defense Test and Evaluation Oversight List in 2006, and the vehicle remained under DOT&E oversight for live fire testing in 2010. DOT&E reviewed and approved uparmored HMMWV test planning documents, as required. As a part of its assessment of the survivability of the up-armored HMMWV, DOT&E originally planned to use ATEC’s HMMWV Live Fire Report. However, on April 23, 2010, DOT&E issued a memorandum to the Service test community stating that DOT&E will publish an independent report before the completion of the test agency report, if necessary to ensure the timely reporting of operational and live fire test results. Therefore, DOT&E will start its assessment of the survivability of the up-armored HMMWV whether or not ATEC has provided its HMMWV LFT&E report. The Director, Live Fire Test and Evaluation, stated that DOT&E will publish a HMMWV LFT&E report by the end of 2010.

DoD’s SBIR program funds early-stage R&D projects at small technology companies—projects which serve a DoD need and have the potential for commercialization in private sector and/or military markets. The program, funded at approximately $1.23 billion in FY 2009, is part of a larger (>$2 billion) federal SBIR program administered by twelve federal agencies. As part of its SBIR program, the DoD issues an SBIR solicitation three times a year, describing its R&D needs and inviting R&D proposals from small companies—firms organized for profit with 500 or fewer employees, including all affiliated firms. Companies apply first for a six-month to nine-month phase I award of $70,000 to $150,000 to test the scientific, technical, and commercial merit and feasibility of a particular concept. If phase I proves successful, the company may be invited to apply for a twoyear phase II award of $500,000 to $1,000,000 to further develop the concept, usually to the prototype stage. Proposals are judged competitively on the basis of scientific, technical, and commercial merit. Following completion of phase II, small companies are expected to obtain funding from the private sector and/or non-SBIR government sources (in “phase III”) to develop the concept into a product for sale in private sector and/or military markets. Service projects for the most current release follow.
US Army Direct Ethanol Fuel Cell PEO Ground Combat Systems wants to develop a direct ethanol fuel cell system that is capable of converting ethanol fuel into electricity in an efficient, small, lightweight, portable power system. Ethanol has a 33 percent higher energy density than methanol, the current fuel being evaluated for small soldier power systems (8000 vs. 6000 Wh/kg). Direct ethanol fuel cells have recently been receiving increased attention in the literature however, previous studies in acidic media have demonstrated only 2 or 4 electrons generated per ethanol molecule rather than the 12 that are possible when ethanol is fully oxidized resulting in poor system efficiencies. The recent development alkaline membranes that conduct hydroxyl ions (OH-) makes alkaline membrane fuel cells very attractive largely due to more facile kinetics for both the fuel oxidation and oxygen reduction reactions. The rapid kinetics makes the use of catalysts with lower noble metal contents feasible and potentially enable the cleavage of carbon carbon bonds at low temperatures. Use of ethanol as a fuel in alkaline membrane fuel cells has the potential to significantly increase the fuel utilization and fuel cell performance, lower the cost and improve safety.
PHASE I: In phase I preliminary results from a stack showing complete oxidation of ethanol to produce electrical energy at low temperature will be demonstrated. These results should support the potential to develop a 40W system which can operate at a power density over 150 mW/cm2, and system energy density over 1000 Wh/kg. PHASE II: In phase II, based on the results from the successful phase I program, two 40W direct ethanol fuel cell systems with power densities over 150 mW/cm2, and system energy densities over 1000 Wh/kg will be developed and delivered to the US Army for testing and evaluation. PHASE III: Advanced alkaline direct ethanol fuel cell technology will significantly impact both military and commercial applications, accelerating product development, particularly for lightweight low power devices. Because the market and the number of devices in the commercial sector is much larger than the military market, widespread usage of this technology will drive down the cost of devices for the military and ensure a reliable manufacturing base. The alkaline membrane technology and optimized catalysts will transition into fuel cell system technology for dismounted soldiers. Likely sources of funding if the phase III program is successful include PEO Soldier and CERDEC. Applications for the advanced direct ethanol fuel cell system include soldier power

To address this need, an IED defeat (IEDD) intelligent behavior engine (IBE) is sought that can enable low-cost, mid-sized vehicles to protect dismounted troops on deep insertion missions. An IBE can be understood as a software tool that provides intelligent control for orchestrating vehicle hardware and software components towards mission goals. The IBE should be portable and reconfigurable so that it can interface seamlessly with multiple payloads, vehicles and sensors. While a highly skilled human operator may understand how to hold a sensor; where to position it; and what areas of the environment to investigate, successfully translating that skill into effective autonomous machine behavior is an open problem that requires innovation. A solution that merely integrates sensors with vehicles will not be sufficient. Rather, the IBE should focus on intelligent, adaptive software behaviors that provide standoff operation in terms of navigation, detection and neutralization. The IBE should allow the operator to initiate, monitor and sequence IEDD task elements such as scanning, digging and emplacing explosive charges. Specific areas for innovation include, but are not limited to the following: Shared control driving: On long distance dismounted patrols, users require a standoff control scheme that offers off-board, “backseat driving� capabilities. The IBE should permit operators to provide intermittent directional cues and to initiate various specific threat detection behaviors from a hand-held device that may include a visualization of nearby terrain and hazard data. Characterization and Neutralization Behaviors: The variation in threats faced by warfighters must be met with versatility in terms of robotic capacity for using multiple hazard sensors effectively. These behaviors must effectively encapsulate the skill and techniques necessary to exploit hazard sensors, marking tools, and neutralization devices including how far from a surface to scan a particular sensor, how fast to scan it, and the advance rate of the vehicle while using a particular tool. Intelligent Manipulation Control: The IBE should address general purpose manipulation skills that can be effectively used with hydraulic or electric arms to perform various reaching, scanning, sampling and digging tasks associated with the IEDD mission. The mid-sized (500-3,000 pound) vehicle en-
Emerging Defense Technologies
visioned should be off-the-shelf and capable of traversing long distances on narrow, rugged paths and of supporting skid steer hydraulic arm attachments for various implements such as arms. Effective teams will provide a means to demonstrate at least one method for sensing buried hazards and one means for neutralizing them. Proposal teams may address key elements of the IEDD mission including pressure activated devices and command detonated explosive devices. The main focus of the work is not on the vehicle but rather the ability for intelligent software behaviors and human interfaces to support effective, semiautonomous functionality that reduces workload and maximizes performance. PHASE I: Conduct study/analysis of current IEDD tools and components that can be used from a mid-sized vehicle. By the end of Phase I, develop a plan includes a list and description of proposed IEDD tools (sensors) and the strategy for behaviors that maximize performance of each tool. The plan should include an interface control strategy to support tasking and situation awareness. The implementation plan should focus on the software and hardware strategy for plug and play of each tool. PHASE II: Develop and refine the prototype toolkit in terms of hardware and software. Demonstration plug and play of subsystem components together with functionality of behaviors and operational tasking from the graphical interface. The Phase II hardware/ software solution can be defined as follows: 1) Graphical user interface, Intelligent Behavior Engines, and other systems analysis toolkit functionality will reside on a rugged field ready laptop computer 2) from inside the vehicle the laptop computer will interface outside in front of the vehicle to a portable plug and play station suitable for mount on a medium sized vehicle. The plug and play station must be designed to be field rugged and not greater than 1 cubic foot. The plug and play station will be used as the interface from the control computer to various IED detect, locate, or defeat systems. The Phase II prototype and test system should be capable of supporting a warfighter assessment of system capability including vehicle mobility, navigation behavior subsystem, communication subsystem, and hand held operator control unit with visualization and tasking software. The system will also include at least one neutralization subsystem, one manipulator subsystem, one underground imaging systems (e.g. ground penetrating radar, electromagnetic induction sensor) and one chemical analysis sensor for sweeping and/or sampling. Com-

ponent hardware/software interfaces will be fully documented and, where appropriate, conform to open architecture/messaging standards. PHASE III: Transition to Military - The most likely path from SBIR to operational capability will be via Phase II enhancement and/ or CPP which would allow final definition of the number and type of IED defeat systems necessary, and the efficient implementation of these systems on the vehicle. At this stage of the program close interaction with PM-IED Defeat and JIEDDO will facilitate development of a robust transition plan that identifies the IED Defeat subsystems necessary, overall system delivery schedule and cost per system. A potential path to fielding will be to pursue a rapid equipment fielding exercise, where the prototype Intelligent Behavior Engine will be used to define a suite of sensors and techniques for IED detect/defeat on medium sized vehicles for rough terrain operations. As part of this user evaluation phase there is also the potential to use the system to enhance or redefine the functionality of existing IED in-road defeat systems. In parallel, Phase III transition may be facilitated via user-centric warfighter experiments to examine concepts of operation and to hone the system behavior and overall performance. Military end applications for the IBE plug and play station and development environment may include 1) improved IED defeat systems for in-road or off-road, improved tunnel defeat systems which require a robust synergism of sensor types and 3) smart munitions systems which have complex functionality and would benefit from improved data fusion using a variety of sensor modalities. Commercial Applications - A portable system laptop computer with interface station which allows a user to evaluate the synergy of subsystems in a plug and play environment while conforming to open architecture/messaging standards would have potential commercial market appeal. Such a system would reduce the development time normally associated with complex systems integration efforts. The system might find application in 1) sensor companies for evaluating new sensor products or the integration of several products together to meet special customer requirements 2) surveillance systems companies to expand the functionality and performance of surveillance systems using different surveillance sensor systems.

January 2011 Water Generation from Atmospheric Humidity Technologies PEO Combat Support & Combat Service Support wants to develop a scalable energyefficient technology to generate potable water from atmospheric humidity in hot arid environments. This technology must be adaptable to compact, rugged, mobile, water generation systems to support soldiers deployed in field environments. Water purification technology has undergone significant advances in the past few decades, however, water sustainment on the battlefield still follows the age old practice of locating a water source, treating the water to make it potable, and then transporting the water in bulky containers to the soldiers. For the current forces over half of the sustainment requirement is the distribution of bulk liquids. As the Army evolves into a lighter and more deployable force focused on the concept of force projection water distribution becomes an even larger concern for military logistics. The ability to generate water at the point of use would reduce or even eliminate the transportation requirement and have a cascading effect on reducing the overall logistics requirement of the force. The goal is to develop a system that has the capability to generate water on demand when no traditional source (i.e. river, lake, or ocean) is available using atmospheric humidity. The Army is not interested in simple refrigeration systems but rather novel technologies that reduce the energy requirements, size, and weight of the system. Current state of the art systems use mechanical vapor compression cooling systems with or without energy recovery and desiccant humidity concentration. These systems are energy intensive, requiring on the order of 570 watt-hour per liter of water produced for ambient conditions of 70 degrees F and 40 percent relative humidity. Additionally these types of systems do not scale down well to mobile systems. The system must be able to generate potable water in sufficient quantities in all environments, including nuclear, chemical and biologically contaminated areas. The water generation units should be scalable to any size, sustainable, and generate enough water to be of use to the DoD in a timely fashion. As a baseline the system should have a production rate at least equal to the current military systems, for traditional sources, of the same size, weight, and power consumption. PHASE I: Laboratory experiments and a proof of concept benchtop breadboard system should be completed. These experiments
23 should demonstrate the capability to produce water from atmospheric humidity at 285 watt hour per liter or less at ambient conditions of 70 degrees F and 40 percent relative humidity. The system should also be able to produce water at conditions of 2 grams of water per kilogram of air at a maximum of 1140 watt hour per liter. The experiments should also demonstrate the feasibility of continuous operation. A conceptual design shall be provided demonstrating the feasibility of a 500 gallon per day system that would be transportable on a 5 ton trailer. PHASE II: Based on best design parameters discovered in Phase I build and demonstrate a demonstrator which can be used by various military and other defense and support organizations for military, humanitarian assistance, and disaster relief operations. The demonstrator will be skid or pallet mounted, produce at least 2 gallons per hour, with an onboard storage capacity of 10 gallons and be able to operate for 24 hours without any required maintenance. The system will meet the phase I energy metrics and the product water will meet Technical Bulletin Medical 577 water quality standards. PHASE III: Build scaled system to meet the needs for use at an expeditionary Army water treatment site and for humanitarian relief efforts. Create a manufacturing plan that will facilitate both product scaling and low rate initial production of both military and emergency response units. Expeditionary Wastewater Treatment Technologies PEO Combat Support & Combat Service Support wants to develop and demonstrate a high recovery, energy efficient gray and black wastewater treatment system that can be used to support a 150 person Army base camp during expeditionary operations. The current and future demands of a highly mobile, resource limited Army base camp call for new/advancements in technologies for wastewater treatment and reuse. The Army must continue to improve and optimize its water management to meet mission requirements. The need for reductions in the water supply burden of base camp operations and the safe discharge of wastewater require innovative technologies with the capability to treat gray (i.e., shower, kitchen, laundry) and black water (i.e., toilet) so that it can be discharged into the environment, thus eliminating the need for waste hauling. Shower water re-use systems (SWRS) are currently being
www.defense-house.com
employed in base camp operations to reduce water supply, however there is still a need for reducing the amount of wastewater that must be hauled from base camps. The Army has identified the following areas as key technology challenges to developing and fielding a wastewater treatment system for base camp applications; rapid start up of biological systems, the ability to adapt to widely varying load conditions, and the reduction of the system energy demand. Examples of technologies that have been identified with the potential to address the key technology challenges are: integration of biological processes with physical/chemical processes, microbial fuel cells, and hollow fiber membrane biofilm reactors. These respectively provide potential approaches to reduce the impact of variable loading and reduce volume, reduce the energy and possible export energy by capturing energy available in the waste stream and addressing all of the areas above through the efficient delivery of gases to a fixed biofilm on a physical separation media. An acceptable technology solution should be energy efficient, lowmaintenance, provide high recovery, and be operational over a wide range of temperatures (-25 F to 140 F). The system needs to meet the Army requirement to be deployable and mobile. This means the system must be set up and fully operational within 1 to 2 days. The system must also be adaptable to different and variable influent wastewater quality. Minimization of the production of any harmful discharge/by-products and any consumables needed is required; avoidance of these items is optimal. The system should be able to treat a capacity of 3,000-12,000 gallons/ day. Power requirement should not exceed 29kW and the ability to use variable power sources including alternative energy sources is desirable. PHASE I: A proof of concept laboratoryscale to breadboard unit that treats wastewater should be constructed and laboratory characterization experiments completed. Finalize a conceptual design for developing and prototyping a material system that is suitable for use by a small Army unit for expeditionary operations. PHASE II: Based on best design parameters discovered in Phase I, build and demonstrate a quarter-scale pallet/skid-mounted prototype demonstrator that can be tested in a relevant environment. The system shall produce an effluent that meets or exceeds the EPA National Pollutant Discharge Elimination System limits for secondary treatment BOD 30 mg/L, TSS 30 mg/L, pH 6-9, and
Emerging Defense Technologies
24 removal 85 percent for BOD and TSS. A final prototype demonstration will be required 12 months from the initial demonstration that incorporates any updated user requirements and design changes. The final system should not exceed a pack out volume of 416 cubic feet and should weigh less than 7,110 pounds. The unit should be easy to operate with the ability to provide unattended automatic operation, provide real time system monitoring and be self-monitoring. PHASE III: Build a commercialization scaled system to meet the wastewater treatment needs for a small unit (150 person) expeditionary base camp site and demonstrate the system in a relevant environment. Create a manufacturing plan that will facilitate both product scaling and low rate initial production of the system. Potential commercial applications of the system would include humanitarian assistance and disaster relief efforts. Development of High Power Density Final Drive for the Bradley Infantry Fighting Vehicle PEO Ground Combat Systems wants to conduct basic research into the development of a high power density final drive for the Bradley infantry fighting vehicle. Due to the installation of heavy survivability kits on today’s fleet of combat tracked vehicles, the mobility performance of these vehicles have degraded from the increased vehicle weight and many platforms no longer meet mobility requirements. Efforts are underway to recapture the lost mobility performance through mobility upgrades of the engines, transmissions, final drives, and suspension systems. The practical approach is to recover lost mobility without requiring undesirable vehicle structural changes for integration. To achieve this, higher power density solutions are necessary so that more power can be generated and transmitted within the existing or smaller space claims. The Army has put significant effort in improving the power density of engines and transmissions; however, little effort has been placed on exploring opportunities to improve the power density of final drives. As vehicle horsepower increases to overcome vehicle weight growth, it is highly desirable to upgrade the final drive systems with new technologies so that they can transmit more power within their current packaging environment. The Army is seeking innovative technology for cost effectively increasing the power density of final drive gearbox assemblies.
Emerging Defense Technologies
Innovative solutions must allow for the provision of upgraded final drives for today’s tracked vehicles that are identical in form and fit to today’s final drive assemblies, but with the ability to transmit more power. Today’s fleet of tracked vehicles would benefit by offering technology for increasing mobility performance without requiring significant changes to the surrounding final drive interfaces such as the vehicle structure, track system, or powerpack. Future Ground Combat Vehicle (GCV) design and development efforts would also benefit by offering improved final drive technology to maximize the mobility performance of this new tracked vehicle. Proposed SBIR will be concentrated on power transmission for increased torque and horsepower capacity. Research will also investigate weight savings and efficiency gains. Expected gains are an increase in power transmission from 600 hp to 800 hp and a torque capacity of 62,000 ft-lbs for a finite duration while maintaining the same space claim. A weight savings of 20 percent and a 1-3 percent efficiency gain will be target objectives. Innovative solutions that could improve power density of final drives include those for gear geometry, material selection and heat treating, coatings, lubrication, fabrication, and integration. Innovative concepts for reducing weight, improving efficiency, providing a quick driveline disconnect, reducing costs, and providing for condition based maintenance are desirable in addition to those that improve power density. PHASE I: Evaluate feasibility of three concepts for improved final drive power density; including gear design and configuration, tribology studies, and application of existing light weight or composite materials (such as aluminum or magnesium alloy housings). Perform an analysis to select the best technical approach for a Phase 2 design, build, and demonstration phase. Demonstrate performance, weight, and efficiency improvements (see above metrics) through modeling and simulation with supporting engineering analyses. PHASE II: Improve and refine, test, and apply concepts to current Bradley final drive. Analyze further, design, and produce one or more prototype final drive sets for dynamometer test and evaluation (demonstrate technology feasibility). Commercial applications where high power density geared systems are sought would benefit from this technology. For example, wind turbine power generation, mining and heavy construction equipment manufacturers would significantly benefit from
January 2011
light weight, high power density gearbox solutions with increased efficiencies. Develop commercialization plans to identify target partners (both military and commercial) and facilitate the technology transition to manufacturing. PHASE III: By partnering with a tracked vehicle platform integrator, develop, validate, and launch the higher power density final drive into Bradley combat vehicle. If successful, the technology will be adaptable to other platforms and transferable across the Army’s existing fleet of tracked vehicles as well as new tracked vehicle development. Commercial applications where high power density geared systems are sought would benefit from this technology. For example, wind turbine power generation, mining and heavy construction equipment manufacturers would significantly benefit from light weight, high power density gearbox solutions with increased efficiencies. High Efficiency Fans for Underhood Cooling of Military Vehicles PEO Ground Combat Systems wants to find highly efficient cooling fans that can be integrated for underhood cooling of military combat, tactical and commercial vehicles which will improve vehicle operational capability in hot climates. Currently many vehicles in the Army fleet are using inexpensive, low technology, automotive axial flow fans which are in the neighborhood of 43 percent efficiency (static). More advanced technology fans have been implemented into a few vehicles which are in the neighborhood of 75 percent efficient. The static efficiency of a fan is a measure of how effectively a fan moves air against the system resistance. Static pressure times the airflow rate times a constant divided by static efficiency equals fan power. If static efficiency is increased, with the same airflow and pressure coming out of the fan, then the horsepower requirement for the fan is reduced, thereby providing more power for mobility. This additional power is significant, and can contribute to upwards of 8% more horsepower to be utilized for other vehicle requirements, or for operating in hot ambient environments. With improved fan efficiencies, more power can be dedicated to powering up hills, along with accelerating along level surfaces, or powering auxiliary equipment. Additionally, better vehicle fuel economy can also be achieved by operating with more efficient fans. Building a compact fan that fits within
www.defense-house.com
January 2011 the tight space-claim of military vehicles is paramount. Military vehicles generally require a cooling system capable of maintaining engine and transmission operating temperatures within specified limits while operating continuously under full load at 0.7 Tractive Effort to Gross Vehicle Weight ratio (TE/GVW) under the maximum conditions of +120 degrees F, and the cooling system must be capable of not exceeding temperature limits while operating at rated engine power (tractive effort is the force exerted at the running gear to propel the vehicle). At the end of Phase 3, meeting this full-load tractive effort at 120 degrees F is the goal of the program for the target vehicles utilizing the fan developed under this SBIR. Two separate fans will be developed in order to target both combat and tactical vehicles. The combat vehicle planned for integration of the first fan will be the Paladin Integrated Management (PIM) vehicle, known as the PIM Paladin. The PIM Paladin is targeted for a cooling upgrade. The PIM has a Bradley powerpack with a different integrated cooling pack. Independent PIM TARDEC full-load cooling tests are upcoming within the next year. The tactical vehicle target for integration of the second fan will be Variant C of the Joint Light Tactical Vehicle (JLTV). The JLTV vehicle most closely matches the requirements of a commercial truck and thus satisfies the commercialization requirement in the SBIR goals. The SBIRs initial build will be for fans with a minimum static efficiency of 85 percent. This efficiency exceeds the efficiency of any vehicle fan known to be built. The innovative approach will attempt to meet the flowrate and pressure rise requirements while increasing the efficiency of the fan. A research and development approach will be needed in order to achieve the efficiencies required for the effort. Mixed-flow fan and accelerated vaneaxial flow fans are currently used in higher-efficiency applications (50-75 percent efficient range), however the offerer will have the freedom to explore the flow pattern that makes sense for the effort. This effort will be completed within the minimal space-claim that will allow for retrofitting into existing military vehicles. The first phase will be a study to define the efficiency and component geometry of an underhood fan using technical engineering analysis which will include a computational fluid dynamics (CFD) study. This CFD modeling will provide a defined envelope for the pressure and flow requirements of the PIM and JLTV vehicles. It will also provide details of the blade
25 and housing design of the fan. In Phase 2, an initial prototype will be built and component tested. Additional CFD modeling will occur as the phase 1 modeling will be validated, and improvements and design improvements will be analyzed. Two fans will then be provided to the government for internal testing. In Phase 3, the contractor will be provided a vehicle from the Army for integrating the fan and conducting relevant testing. Testing will focus on maintaining engine and transmission operating temperatures within specified limits while operating continuously under full load at 0.7 tractive effort to gross vehicle weight ratio (TE/GVW) under the maximum conditions of +120 degrees F. PHASE I: Complete a feasibility study and preliminary design report for a high-efficiency fan build that fits the geometry space claim defined by the government. This will include a computation fluid dynamics study which will define and develop the fan requirements. Following this study, deliver sufficient initial fan design details to the Government to allow analysis within TARDEC’s CASSI business group. PHASE II: Build an initial prototype fan, and component test the fan. Use CFD to refine the fan design. With the lessons learned from this initial prototype, design and build a follow-on fan. Complete the component testing. Make fan available for government testing. PHASE III: With the vehicles provided by the Army integrate the fan into the vehicles. Complete full-throttle, hot climate testing. If successful, complete engineering change proposal for the Army vehicle(s). Production fans can be then integrated into vehicles, as required. Commercial truck applications which more closely match with the JLTV vehicle will be explored in order to reduce the overall production costs to the government. Advanced High Voltage Optical Switches for Launchable Compact RF Warheads PEO Missiles and Space wants to develop a high voltage optical switch direct to RF conversion technology which integrates the switching light source and high voltage source within the supporting RF transmission line to form a self contained RF module that could be inserted into either the GMLRS or ATACMS missile platform. It has been shown that high voltage optical switches can be effectively integrated into a charged transmission line, at appropriate in-
www.defense-house.com
tervals, to create a direct DC to RF conversion of electrical energy in a frozen wave structure. These systems can be quite compact and effective against IED electronics and other electronic systems with the potential of long range interdiction, however they require an external high energy laser system to trigger the switching circuits, which limit the application and the size of the platform on which they could be mounted. They also require medium range high voltage sources mounted externally to the transmission lines for between pulse charging of the RF circuits, increasing the hazard and complexity of the system. The focus of the SBIR topic to create a charged transmission line with integrated optical switches that also integrates the laser trigger source onto the transmission line as well as the high voltage power supply. The final embodiment of this effort will be an integrated module that can be stacked into arrays to form high power RF modules for a multitude of applications. The modules should be of size and volume to fit within either the GMLRS or ATACMS payload bay and be totally self contained. The desired payload specifications are:
1. Total weight <200 lbs including power supply 2. A diameter less than 7.5 inches 3. A length less than 3 feet
The RF source developed under this research should operate at a frequency of either 915 MHz or 1.3 GHz and produce a minimum of 5 RF cycles. It should be able to operate for a minimum of 10 seconds with a pulse repetition rate of 1 kHz. The source should generate a nominal electric field of 50,000 V/m normalized to 1 meter. There is no preference as to the antenna pattern, gain, or beam width. PHASE I: Investigate methods for incorporating the optical source technology and high voltage source within the supporting RF transmission line. This should include a trade study with predictions as to size and volume of the proposed RF modules and a basic demonstration of the optical switching technology. The source should be designed with shock hardening in mind with plans for the final embodiment to be hardened for missile launch. PHASE II: Develop and demonstrate a standalone module and demonstrate free field RF transmission within a laboratory environment. The device should be capable of producing a frequency of 915 MHz or 1.3
Emerging Defense Technologies
26 GHz with a minimum of pulse length of 5 RF cycles. It should be able to operate for a minimum of 10 seconds with a pulse repetition rate of 1 kHz. The device should generate a nominal electric field of 50,000 V/m normalized to 1 meter. PHASE III: The final embodiment of the module developed in phase II, would be a flight hardened, drop in device, which would be test launched on either a GMLRS or other in inventory GFE missile. At this phase of development, which would result in a TRL level 5 device, demonstrations of effectiveness would be sought and demonstrations of fly ability of the source would be performed. Innovative Appliqué Attachment Methods for Army Vehicles PEO Combat Support & Combat Service Support is looking at the integration of armor packages for ground combat systems. New armor packages will be mounted to vehicle structures using successfully developed technology. The Army is in need of innovative methods of attaching Appliqué armor packages to combat vehicle structures. Many of these armor packages use non-traditional materials as a part of the package. These materials are very effective at increasing the protection level of the armor, and also reducing the weight burden on the vehicles. However, the methods of attaching these armor packages have not had a similar increase in effectiveness. The Army is looking to increase the capabilities of appliqué attachments in several areas: 1. Current attachment methods that are effective are not quick to remove. In order to make needed combat vehicle repairs the attachment methods need to be quickly removed with either simple tools or no tools. This can be an issue as typically attachment methods that can be taken off easily do not hold under the large dynamic loading conditions seen by combat vehicles. 2. Current attachment methods need to improve isolation from vehicle automotive loading. The appliqué can be more optimally designed if they do not need to endure as much structural loading. Improved methods of isolation are required. 3. There is a potential that additional appliqués can be added on top of existing appliqués. These appliqués would be daisy-chained 2 (and potentially 3) deep. Attachment methods that can be robust
Emerging Defense Technologies
enough to handle the additional weight (~100 pounds) and the resulting cantilever burden are desired. In addition, it would be desirable that a process to perform the daisy chain is highly desirable, as well. 4. The development of attachment concepts needs to be weight efficient. The Army has significant interest in increasing soldier protection while decreasing weight. The ability to meet our needs with reasonable weights is most essential to our continued success. PHASE I: Phase I should be a concept development phase. The selected contractor will be able to finalize the design parameters with the government and develop between 4 to 6 design concepts. As a part of the design downselect, a vehicle system for testing will be selected. These design concepts should be an entire panel system. The attachment method does not need to be just one type of attachment, but could be an attachment system. However, commonality is favored if and when possible. The concepts shall be developed and presented with supporting evidence for each concept, and a final evaluation. The details of the supporting evidence would be at the discretion of the contractor. However, such evidence may include (but is not limited too) engineering analysis. Material strength data, prototype (or similar design) demonstration, finite element analysis (FEA). Up to two concepts could be downselected for Phase II. PHASE II: Phase II of this program would involve the testing and further development of the two concepts developed during in Phase I. Prototypes of the downselected concept(s) shall be fabricated and tested under a battery of tests that should include structural, environmental, and ballistic testing. Additional tests may include testing the time it takes to install and remove. The parameters of the testing conditions will be based upon the vehicle system selected in Phase I. PHASE III: This system does have vast defense vehicle capabilities depending on the degree of success and the adaptability of the final solution. Many current vehicles are employing a system of appliqué armors that could benefit from better attachment methods. In addition, the commercial application of an attachment method that is robust, lightweight, and easily detachable are probably fairly significant.

Increased Autonomous Vehicle Mission Performance Using Advanced Electrical Architectures By optimizing a small (100 pounds or less such as a Talon/Packbot) autonomous unmanned ground system’s (AUGS) power storage, generation, and distribution as well as utilizing new power sources and energy storage technology (batteries, ultra-capacitors, fuel cells, hybrid-electric), the goals of this PEO Ground Combat Systems effort are to improve the mission capability and ensure payload delivery of small unmanned ground robotic systems by: 1) Increasing AUGS power availability and mission length 2) Increasing AUGS energy storage capability 3) Increasing AUGS system efficiency Promising solutions will improve mission capability by at least 25 percent with an objective target of 40 percent, will be compact, light weight, and will be easily configurable and transferable to multiple systems. A field upgradeable kit that includes hardware and software deliverables is envisioned. Small (100 pounds or less) AUGS are increasingly important to the US Army and its military and logistical operations. Each AUGS platform has a different main purpose and AUGS platforms can be physically configured for different mission priorities and payloads. The Department of the Army, TARDEC GVPM, TARDEC IGS, the RS JPO, and the NAC are collaborating to develop practical and cost effective ways of extending mission life without extensive re-design/ modification. Early investigative studies predict that intelligent contribution from energy storage devices and improvements resulting from advanced system-level power management and control could increase the mission capability, having a positive impact across robotic system platforms. PHASE I: Phase I will result in a design concept for a configurable and scalable intelligent power management system, which can be added to a variety of AUGS platforms. Technical feasibility and commercial viability will be essential considerations in the Phase I study. PHASE II: Phase II will entail the design and development of the Phase I design concept. During the duration of Phase II, prototypes of the design concept will be built, configured, and implemented on several generic AUGS systems in bench-level technol-

January 2011 ogy demonstrators. Objective measurements will be made with a manual or semi-automated data acquisition system. Data will be analyzed and presented at design reviews and will be captured in a final technical report. All SBIR results (including, but not limited to, designs, drawings, electrical schematics, software source code) will be delivered at the conclusion of the program. PHASE III: The results of the SBIR effort could be applied to military manned and unmanned ground vehicle systems to ensure mission payload and to extend silent watch missions. Commercial application could include autonomous robotic systems that operate in manufacturing environments and small electric vehicle systems that rely on battery operation. High-Strength, Lightweight Material for a Bridge Applications PEO Ground Combat Systems is using this SBIR to research an innovative material for use in bridge structures. This material needs to be lightweight, have high strength, high durability, good weather resistance, and high survivability. The material is desired to be used in the entire bridge structure as the main structural components. However, the material could also be used as an enhancement in conjunction with other materials, forming the main structural components. There is no restriction on whether the material is a fiber, ceramic, plastic, or other. A material solution that is only metal is not the desired result. The material has many desired properties. For ease, the material will be compared to common bridge materials such as steel and aluminum. Ideally, the material solution would allow for approximately a 50 percent (25 percent) weight reduction in comparison to a similar steel (aluminum) structure. Ideally, this material would possess similar qualities as steel and aluminum; however, have a much greater strength-to-weight ratio. This material needs to withstand a large number of fatigue cycles, both for deck wear and structural fatigue. The desired fatigue limit would be 80 percent of the ultimate stress for the given material. Ideally, the material would not sustain a single, catastrophic, brittle failure like many fibrous materials; rather a slow, ductile failure is desired for safety. Fracture toughness 25 percent (50 percent) greater than steel (aluminum) would be desired. This material needs to withstand a wide variety of climates without any degradation in performance. Climates can be defined as temperature range
27 (Ë&#x153;-25°F up to 125°F), extended UV exposure, precipitation, sandstorms, wildlife, etc. The material would be able to withstand all climates for 20 years without needing maintenance due to corrosion. It is desired that a single, concentrated, high impact would not compromise performance of the material. In addition to the desired material properties, there are several desired attributes. If the material is used in conjunction with or attached to other materials, a solution for connecting the different materials is necessary. The desired deflection of the bridge under full load would be comparable to a similar structure made of steel or aluminum. It is desired to not increase the weight of the structure by more than 5 percent when using a deflection controlled design as compared to any other failure mode. If the material is used in conjunction with another material, it is desired that the materials have similar thermal expansion properties. Ideally, the method of producing the material and assembling the structure would be able to be done in a remote location with limited equipment. PHASE I: Design and develop the concept material along with testing. During the Phase I effort, analysis of the technical approach proposed should be conducted in detail. This analysis should include discussions with TARDEC to identify the specific requirements for application of the process to a bridge. A preliminary analysis of the potential materials and projected cost of the proposed approach should be conducted. Small scale manufacturing trials and material characterization testing may be conducted to establish basic feasibility and guide the effort to be conducted in Phase II. PHASE II: Develop, test and demonstrate concept material in a WADI bridge design. The results of the Phase I effort shall be further developed to scale-up the proposed approach and optimize the material methods. Coordination of the specific approach for optimization and scale-up effort with a WADI bridge. This development work shall be supported by necessary design and modeling effort. Manufacturing trials and material property development of increased complexity shall be conducted to evaluate the performance of the specific approach. Application of the material process to a full scale bridge shall be conducted. Fatigue testing to establish the potential benefits shall be conducted. Potential material applications shall be identified and plans for technology insertion and product development conducted. PHASE III: Material concept would be used on and in the bridging structures to

lessen the weight of the overall bridge but could be used to reduce the weight of armor protection. The commercial potential for this material could be lightweight bridging components. Effort in this phase would involve further collaboration with the bridging manufacturers regarding design and manufacture of a specific component to which the process could be applied. Additional testing to further prove the advantages of the material and potentially qualify it for service could be performed. Advanced Rotary Diesel Engine Fuel Injection System for Unmanned and Manned Ground Vehicles PEO Ground Combat Systems wants to examine, develop, and demonstrate the use of an advanced high pressure injection system in a heavy-fuel (DF-2 and JP-8 compatibility), rotary diesel engine for unmanned and manned ground vehicle applications. There currently is a shortcoming of heavy fuel engines that have a rated power between 10 and 80 BHP and are compatible with both JP-8 and DF-2, have high power to weight and power to volume density, provide good fuel consumption characteristics, and operate over extreme climatic ranges ranging from below -25 F to 125 F ambient. Today it is difficult to adapt light-duty, automotive diesel piston engines for such applications while meeting power density, packaging, and heavy fuel needs and thus other options are under exploration. One developing technology that could potentially fit this niche market are heavy fuel, rotary diesel engines that can provide from 10 BHP to 60 BHP per rotor, have peak brake fuel consumption less than 0.5 lbm/bhp-hr, and have an engine power density of 1 hp/lbm for ground vehicle applications. A major challenge with such engines revolves around the combustion system development of which the fuel injection system presents a significant challenge due to difficult spray targeting length and time scales associated with rotary diesel combustion systems. Such combustion chamber geometry have significant challenges in properly targeting injector nozzle geometry for JP-8 and DF-2 due the time varying impingement length of each injector spray and the limitation on rotor pocket geometry for enhancing spray mixing and combustion rates without excessive liquid fuel rotor impingement. This topic will focus on developing a flexible, high pressure fuel injection system that can be integrated onto a heavy-fuel, rotary diesel
Emerging Defense Technologies
28 engine and meet the aforementioned power density, power to weight, power to volume, and climatic operating range conditions. Such a fuel system should be able to vary start of injection timing, deliver multiple injection events when necessary, and provide adequate spray formation to avoid excessive wall wetting while providing combustion characteristics amenable to both JP-8 and DF-2. PHASE I: Identify and assess fuel injection technology that will meet the performance specifications described in the description section and also provide a relevant bench top demonstration. Assessment should include any necessary zero- or multi-dimensional analysis that will aid in selecting the proper fuel injector and nozzle geometry including hole size(s) and angle(s), and the bench top demonstration should provide evidence that the injector has single and multiple injection capability at various injection durations representative of light to high load engine operating conditions and qualitatively has a spray pattern that will minimize combustion chamber wall impingement. The fuel injector should have the capability for multiple injections within the operating speed envelope of a representative rotary diesel with engine shaft speeds up to 5,500 RPM and peak injection pressures between 1000 and 2500 bar. PHASE II: Demonstrate and validate the performance of the chosen phase I fuel injection system on a rotary diesel engine through computational analysis, bench top experimentation, and relevant engine hardware demonstration with the goal of meeting the aforementioned fuel consumption target, the rated power range per rotor, and the specific power characteristics described in the description section using both JP-8 and DF-2. PHASE III: Develop a fuel injection system that can be readily integrated onto a heavy fuel rotary diesel engine for commercial vehicle or military ground vehicle use. The resulting fuel system should be available for rotary diesel engines used in future Army manned and unmanned ground vehicles or as a large vehicle auxiliary power unit ranging from 10 BHP to 80 BHP that delivers sufficient fuel consumption and specific power performance while operating on both DF-2 and JP-8. It is envisioned that this technology will be transitioned to a military rotary diesel engine manufacturer. Lithium Ion Battery Separator Development
PEO Ground Combat Systems wants
Emerging Defense Technologies
to develop an advanced lithium ion battery separator that has high temperature stability in order to increase battery safety. The electrification of tactical military vehicle technologies has been limited by the safety, performance, and excessive costs of power sources and storage devices. Lithium ion batteries have moderate energy density and power density. Lithium ion battery safety hazards, such as thermal runaway, limit their application in extreme military conditions. Residual stress and reduced mechanical properties of separators at high temperatures can lead to shrinkage, tearing, or pinhole formation, which contribute to battery failure. The Army is interested in identifying and developing innovative separator concepts for advanced lithium ion batteries which will improve safety, performance, extend the life, and reduce the cost of the separator. Grant applications must show how proposed innovations would result in significant advances in safety enhancement and cost reduction over state-of-the-art technologies. Therefore, grant applications are sought for new separator that offer high temperature stability (less than 5 percent shrinkage at 220째C or higher) and mechanical strength (tensile Strength: Less than 2 percent offset at 1,000 psi) suitable for lithium ion battery applications. Proposed approaches could involve new polymer materials or composite materials; no limitation is placed on the alternatives that could be considered as long as the temperature stability and mechanical strength goals are met. Proposed materials must also meet all of the design requirements for a lithium-ion separator (performance, thickness, porosity, cost, etc.) at room temperature. PHASE I: The contractor will develop and demonstrate the proposed concept through materials preparation, analysis and evaluation. A research study in the form of a report is expected from phase I deliverables. PHASE II: The contractor shall refine and fully characterize the separator. 5 samples (50 cm2 or larger) shall be delivered for verification and evaluation. The contractor will demonstrate proof of the concept with the fabrication and testing of 4 or more lithium-ion battery cells with produced separator material. The cells can be cylindrical or prismatic format with no less than 2Ah. The performance of the cylindrical and prismatic cells shall be tested and compared with those fabricated with commercial lithium ion battery separators. PHASE III: Separator material developed in this topic could be scale up for the automated production process for mass-pro-
January 2011
duction for commercial and military lithium ion battery applications. The results of the development of the improved separator should enable the incorporation of advanced lithium ion battery configured in a 6T and/or Group 31 configuration into new type of military vehicle systems as well as commercial electric vehicle and hybrid electric vehicles. The goal in this phase will be to initiate the manufacturing processes to produce this separator material for lithium-ion batteries and to evaluate the products for military and commercial applications. Low Cost Embedded Dust Detector (EDD) for M1 Abrams/Ground Combat Vehicle (GCV) PEO Ground Combat Systems wants to develop a low cost embedded dust detector (EDD) for M1 Abrams/GCV and commercial vehicles. The EDD will be integrated into engine to warn an operator of high dust contamination for reducing engine damage and improve vehicle operational readiness. High power density military engine used in M1 Abrams and proposed for Ground Combat Vehicle (GCV) require huge volumes of intake air in order to meet mobility and power generation requirements. Operating these vehicles in desert environments exposes the engine to extended periods of dust contamination which drives up the frequency of air filter servicing, shortening intervals between major engine overhaul/replacement and ultimately increasing operating life cycle costs. The high air flow (up to 10,000 standard cubic feet per minute, SCFM) required for M1 Abrams gas turbine engine must utilizes three air filters to trap the dust contaminants. M1 Abrams equipped with the self- cleaning pulse jet air cleaner (PJAC) provide reduced maintenance but still must be removed, cleaned and inspected on a semi-annual cycle. Non PJAC equipped M1 Abrams require more frequent servicing which can occur as often as every three months. Dust leaks into the engine can occur from the following sources, (1) low efficiency barrier filters, (2) dust falling in clean air plenum during barrier filter removal, (3) seal failures in plenum box and (4) improperly installed inlet plenum seal ring connecting air cleaner box to turbine bell mouth inlet. Thus, it is imperative that the EDD be placed down -stream of all leak sources. The turbine engine used in M1 Abrams is expensive and failures related to dust exposure are being experienced in desert theaters. An EDD will be explored and lab tested to demonstrate that it
www.defense-house.com
January 2011 can measure dust penetration and withstand the shock/vibration and operating temperatures seen in military vehicle environments. Proper placement of an EDD in the turbine engine will be critical for assuring dust particles are sensed by the EDD which will require engine manufacturer participation and coordination. Such an effort was conducted in a dust detector SBIR program in the early 2000’s. At that time design parameters included the following: (1) minimum concentration numbers going into the engine are .025 milligrams per cubic foot of AC fine dust, (2) target goal is to be able to detect 5 micron minimum dust particle size and 200 micron maximum dust particle size with an added goal to be able to measure dust particles between 1 to 5 microns, (3) it must produce a readout within 5 to 50 seconds and (4) it must operate at air flows from 500 to 10,000 SCFM for M1 Abrams. Other design parameters were established under the previous Phase II SBIR project and will be available under reference (3). The previous established design parameters will be reviewed to determine accuracy. The real time EDD in addition to specific design parameters sited above will establish the following design criteria which include, (1) maximum vacuum and pressure limits, (2) tolerance to shock, vibration and noise levels in the engine or vicinity in which it may be located which is downstream of plenum inlet seal, (3) minimum and maximum power consumption and (4) minimum intrusion of any EDD probe in clean air passage of engine inlet. Previous dust detector technology has been explored and installed in an older designed military tank but did not prove reliable and thus failed to achieve success however dust detectors are employed on foreign tanks. A new technology break through that can be integrated into the engine and provide reliability will serve both military and commercial vehicles which must operate in high dust environments and regions of the world. PHASE I: An EDD innovative concept will be designed including the development of a detailed analysis of predicted performance. The design parameters will be thoroughly investigated to determine if previously established design criteria is applicable in today’s dust detector technology and development. The EDD innovative concept will detail computational fluid dynamic (CFD) and finite element analysis (FEA) with support from engine manufacturer, M1 Abrams and vehicle developer as needed. Location of the EDD in the turbine engine will be studied to determine to establish feasibility and practicability. A breadboard design concept will
29 be proposed and demonstrated. PHASE II: The EDD concept will undergo continued development and validation. A prototype breadboard will be constructed and the operation of the prototype will be demonstrated. The location of the EDD in the AGT 1500 turbine engine will be fully evaluated to determine a location which is acceptable and functional. The location of EDD must be approved and design integrity verified as to form fit and function. All design parameter previously established in Phase I will be verified and any changes made or additions will be concurred in by responsible organizations. The prototype EDD based on Phase I work effort will concentrate on lab tests to validate the design parameters. This may include lab testing of the engine and air cleaner system as a package to expose the EDD to a simulated real world condition to harden the EDD design package. Continued development and lab test with/without engine components will be demonstrated. Necessary design changes will be incorporated to meet established EDD design criteria and environmental tests. The triggering mechanism of the EDD will be demonstrated requiring integration into the vehicle software network. This effort will require some support from responsible organizations. PHASE III: The primary Phase III military application of the EDD is the M1 Abrams which uses the AGT 1500 turbine engine requiring up to 10,000 SCFM of air flow. Also, the GCV program which is targeting a diesel engine at around 3000 SCFM would benefit by developing an EDD. Potential commercial application includes mining machines and trucks with large engines which are exposed to dust environments. Measuring Fuel Quantity in Collapsible Fabric Storage Tanks PEO Combat Support & Combat Service Support wants to develop a fuel measuring device that is capable of measuring fuel volume in collapsible fabric tanks with an accuracy of at least ± 1 percent. The Defense Energy Support Center (DESC) is responsible for fuel accountability on the battlefield. DESC is currently developing a system called fuels manager defense (FMD) that will provide real time fuel tracking and inventory management of all fuel on the battlefield. DESC has a fuel accountability accuracy requirement of ±1 percent. There are two methods that the army currently uses to measure fuel volume in collapsible fabric
www.defense-house.com
tanks used to store bulk fuel on the battlefield. Neither of these methods is capable of meeting DESC’s ±1 percent accuracy requirement. The first method is to manually measure the height of the fabric tank with a tape measure and string and then look up the corresponding volume on a table called a strapping chart. This method is labor intensive and does not meet the ±1 percent accuracy requirement. The second method, found in the fuel system supply point (FSSP), uses flow meters on the inlet and outlet of the tanks to determine tank volume by measuring the amount of fuel added to and removed from the tank. The short falls with this method are it can’t account for fuel losses from a leaking tank and over time the cumulative error in the meters results volume measurement errors of ±10 percent or greater. In an effort to find a solution that meets the ±1 percent accuracy requirement from DESC, the Army has evaluated several alternate methods for measuring fuel volume in collapsible fabric tanks over the past two years. These methods have typically used the technical approach of calculating tank volume from measurements taken at single or sometimes multiple points on the tank. Although these methods are more accurate than measuring the height of the tank with a tape measure or flow meters, none of them have been capable of achieving an accuracy level of ± 1 percent. The best case accuracy was in the ±4 percent to ±6 percent range, and that was only achievable after the tank with filled to 10 percent of its total rated capacity. The shortfalls found in the alternative methods that Army is still working to overcome are: 1. In a 10,000 gallon fabric tank, the tank has to be filled with 1,000 gallons (10 percent of rated capacity) of water before tank volume measurements stabilize. 2. Volume levels of less than 1,000 gallons in a 10,000 gallon tank were inaccurate by as much as ±20 percent. 3. From the 1,000 gallon to the 10,000 gallon volume level in a 10,000 gallon tank, accuracy in ±4 percent to ±6 percent range was typical. 4. None of the methods tested were capable of accounting high or low spots in the ground under the tank. 5. Accurate measurements of changes in tank geometry due to material relaxation over time are required. PHASE I: During phase I, develop a technique to measure fuel volume in a collapsible fabric tank to within ±1% over the full volume range in the tank. Phase I will address how to overcome the following limitations experienced with previous tank volume measuring approaches and equipment: 1. The exact size, geometry, and con-
Emerging Defense Technologies
30 struction material of a tank varies by manufacturer and tank. 2. The tank material relaxes over time changing the dimensions of the tank. 3. The ground under the tank is typically not completely level or uniform making it more difficult to accurately measure tank volume due to fuel hiding in low spots. 4. Temperature will cause the tank material to relax and change the tank geometry. 5. The tank height and geometry varies with the volume of fuel in the tank. 6. Consistently achieving a volume measurement accuracy of ±1 percent or better over the full tank volume range. 7. Small size and ease of set up and use are a priority. PHASE II: Based on the results of phase I, construct and test a prototype device capable of measuring fuel in a collapsible fabric tank. All testing and demonstration for this phase will be done with water. PHASE III: The technology developed in phase II will greatly enhance the Army’s ability to account for fuel on the battlefield. This technology will be implemented into the Army’s bulk fuel storage systems such as the inland petroleum system and FSSP that use bulk fabric storage tanks. The capability to measure volume levels in collapsible fabric tanks also has potential use in commercial and industry applications where collapsible fabric tanks are used. Small Diesel Engine for Modular Power PEO Ground Combat Systems wants to develop and demonstrate a 300-500W heavy fuel engine to provide modular power for an unmanned ground vehicle (UGV), replacing a stock battery and extending UGV mission length. Heavy fuel engines are not available commercially off the shelf at extremely low power levels (less than 1 hp). Furthermore, there are presently limits preventing the scaling down of off the shelf diesel/JP-8 engines with respect to combustion: spray, injector size, bore size, etc. Past DoD programs on small modular power generation have provided engine-generator solutions, but focused more on the development of the generator and electrical system, rather than providing an engine with a modern fuel system. Small unmanned ground vehicles (UGVs) such as the Talon and the Packbot are in need of ad-
Emerging Defense Technologies
ditional power generation to extend their mission. Some of these missions include bomb diffusing and reconnaissance missions where it is too dangerous to involve soldiers. An operational needs statement for autonomous unmanned ground surveillance Systems was produced with the threshold of 24 hours runtime at payload and objective of 72 hours. Presently these UGVs have somewhere between 2-6 hours of battery life depending on the battery chemistry and mission profile. The warfighter is in great need of UGV systems that can be operable for the entirety of the mission duration. This limited battery life restricts the missions of the UGVs and may potentially put soldiers in danger. Since the battery life varies greatly, the Army needs a small heavy fuel engine designed to be coupled with a generator that would maintain the state of charge on the batteries of the UGV; thus making the UGV a hybrid system. Maintaining the state of charge on the robots batteries would increase over all mission length significantly. However, there are system constraints because the UGVs are considered to be man portable and are used for many different missions. These UGV system restrictions include weight, noise, and space limitations. These metrics are for the engine and any and all auxiliary systems required for the engine to operate (controls, electronics, cooling, gearboxes, etc), but does not include fuel. Therefore the assembled sum of all engine parts need to be able to meet the power output requirements while meeting the volume and weight requirements simultaneously. The weight of the engine shall not be more than 7.6 kg (T), 1.6 kg (O), which is the weight of one lead acid and one Lithium Ion battery, respectively. The small engine must be able to run on DF-2 (T), both JP-8 and DF-2 (O). In addition, the system shall be considered audibly non-detectable, Level I, by MIL-STD 1474D at a distance of 800 m(T), 400 m(O) due to the nature of the UGVs’ missions. This standard describes the frequency spectrum dB levels of the unit at 30 m distance, then defines the non-detectability distance based on that data. The engine system shall have a volume no larger than 3.2L (T), 0.8L (O). This volume is crucial because the unit will replace a battery in the UGV system’s battery bay. Specific dimensions will be provided to ensure the power system will replace the vehicle battery precisely. PHASE I: Design a heavy fuel engine that meets the objectives of the above description. Use modeling and simulation to validate the design. Deliver a paper describing the accomplishments.
January 2011
PHASE II: Develop the engine designed in Phase I. Build a prototype that meets the power level and space claim provided. Validate the design and the modeling and simulation through testing. Measure the power output of the system as well as operation length. Deliver the prototype with a paper describing the conditions the system subjected to. PHASE III: The engine will be applied to an electric generator, providing power for small UGVs such as the Talon and the Packbot. Adding an engine generator would make the UGV a series hybrid. These small UGVs are used in bomb defusing activities and other reconnaissance missions too dangerous for soldiers. They have a restricted range due to their limited battery life and with an engine generator, the battery life will be extended, there by extending mission length.
Navy Active Laser Protection System PM Advanced Amphibious Assault (PM AAA) (ACAT 1) wants to develop innovative technology approaches to protect vehicle crewmen eyes from frequency-agile lasers. The proliferation of threat lasers possessing multiple wavelengths present a significant danger to ground vehicle crew members looking through direct view optics (vision blocks/ unity periscopes). The present mitigation strategy to protect vehicle crewmen against fixed frequency threats is to filter lasers through narrow band spectral line rejection at the threat laser wavelengths, attenuating incident laser energy at these wavelengths, thus preventing laser radiation from damaging the eyes. The current state-of-the-art approach used to protect against frequency-agile lasers relies on nonlinear optical materials (nonlinear absorbing dyes, nonlinear scattering suspension, etc.) which must be located at the focus of an optical system in order to obtain high fluences necessary to trigger the nonlinear mechanism. Direct view optics carries with them a host of limitations and integration issues that make incorporation of nonlinear mechanisms impractical (field of view, image quality, space claim, cost and complexity, etc.). This SBIR topic solicits new, innovative approaches to provide frequency-agile laser eye protection throughout the visible spectrum. The proposed technology should allow ample transmission of ambient visible light and be of high optical quality so as not to significantly degrade normal vision. It should
www.defense-house.com
January 2011 have a fast response time when exposed to dangerous fluence levels, sufficient to react to and block incident laser pulses to a high optical density. The technology must have a broadband response; blocking any visible wavelength (i.e. 400-700 nanometers) which has sufficient irradiance to damage eyes. The concept should be capable of changing from a high transmission state to a very low transmission state within sufficiently short time to block nearly all of the light contained in a light pulse emitted from a Q-switched laser. When harmful radiation is no longer incident, it must recover to a high transmission state in a short amount of time so that the userâ&#x20AC;&#x2122;s vision is not interrupted or significantly degraded after exposure. The proposal should discuss in detail the spectral transmittance in the attenuating state, activation threshold, response time, optical density in the attenuating state, and recovery time of the technology, as well as any other important technical details. If the technology is capable of exceeding any of the above requirements, the proposal should note this as well. Likewise, the proposal should note any limitations inherent to the proposed technology. PHASE I: Develop a laser protection concept designed to meet the requirements stated. Identify critical technologies for realizing this concept. Conduct theoretical analysis and limited laboratory testing on sample materials or devices to prove the feasibility of the concept. Phase I deliverables will be monthly progress reports, a final technical report, a final review and sample materials or devices. PHASE II: Develop and demonstrate a laser protection prototype system. Prototype should be built in the form, fit and function of, or integrated for use in conjunction with, common periscopes or vision blocks on ground combat vehicles. This prototype shall be tested for laser protection performance and degradation to optical system performance in a laboratory environment. Factors to be considered include, but are not limited to, optical density upon laser illumination, response time, recovery time, linear optical properties under normal daylight illumination, manufacturability, and environmental stability. Phase II deliverables will include a prototype laser protection system, interim sample materials (if applicable), test data, monthly progress reports, semi-annual progress reviews, a final review, and a final report. Depending on the work performed, the Phase II may become a classified program. PHASE III: The most likely Phase III transition path is integration of this technol-
31 ogy into the unity vision periscopes of the expeditionary fighting vehicle.
Special Operations Command Improved Tire Technology for Special Operations Vehicles USSOCOM wants to develop a high speed, true off-road ballistic tire - a tire that can provide high off-road mobility, while also being capable of running at high speeds on primary and secondary roads that also provides improved tire survivability versus terrain and ballistic threats. Current tire technology forces a trade between design for speed, design for stability and design for extreme off-road mobility. Current run-flat solutions, combined with tires and bead locks are very heavy and provide very limited mobility once hit or damaged. Zero pressure tire technology has been around for several years now but has not moved into military applications. The most significant concerns with current state of the art are weight, producibility, and cost, as well as concerns regarding performance and reliability. New tire technologies, approaches, and designs are necessary to optimize for both high speed on-road operation and for off-road operation in aggressive terrain while providing enhanced survivability and damage resistance versus gunfire and terrain. The overarching goal would be for the improved tire technology to be applicable across the full suite of the family of special operations vehicles program to include mine resistant ambush protected vehicles (MRAP variants are RG33, RG31, AUV and M-ATV), the ground mobility vehicle (the special operations forces peculiar HMMWV, currently the M1165), light transportable all terrain vehicle (side by side ATV), ATV (saddle seat), and commercial mobility vehicles (COTS vehicles such as the Toyota pickup truck). An example of the current state of the art is Tireball technology, but that technology is limited because the wheel/Tireballs cannot be replaced or repaired in the field, without special tools and procedures, short of replacing the entire wheel/tire assembly. nother example is the current application for the GMV, which is the Hutchinson VFI runflat inside a load range E wheel and tire combination (Goodyear and Michelin currently produce the tires, while the wheel is manufactured by Accuride or Hutchinson). This wheel/tire/ runflat has a weight of approximately 160
www.defense-house.com
pounds. A limitation with current run-flat solutions are that they have not been ballistically tested; the desired tire technology would be tested for survivability with a threshold of 2 shots of 7.62 x 39 mm PS Steelcore ball and an objective of surviving 2 or more shots of 7.62 x 54R LPS ball. At a minimum, the new tire must allow the vehicle to continue move for at least 30 miles with a complete loss of air pressure in any two tires, with 9 miles (primary/paved road) at 30 mph, 9 miles (secondary roads) at 21 mph and 12 miles (crosscountry) at 12 mph. A successfully developed prototype tire would be subjected to performance testing to meet a commercial or military standard such as SAE J2014. The tire prototype would also ultimately be expected to pass a standard 12,000 mile reliability, availability, maintainability, and durability test at an independent test facility. The initial application for proof of concept would be an 18 inch diameter wheel with a tire size of P275/65R18 such as used on a Toyota pickup truck. PHASE I: Conduct feasibility study to develop or determine technologies that will produce a high-speed, off-road tire that can survive terrain and ballistic threats. Explore scalability of technology. PHASE II: Develop prototype tires and conduct testing to prove technology is viable and can be used to provide a tire solution that is high speed capable (while maintaining or enhancing off-road performance) and provides increased damage resistance and survivability. Explore speed, ride quality characteristics, and performance once damaged. PHASE III: The proposed tire technologies could be directly leveraged to provide enhanced tires for commercial vehicle markets, shipping, and racing applications.
