Working Our Way Around COVID-19

Vidyut Balaji

I

IT Bombay Racing is an entirely student-run team that is continually developing new solutions with one single goal in mind: to make an electric car. One, that, in combination with the driver, travels the distance of a circuit in an amount of time shorter than any other driver/vehicle combination present in the race venue on the day. We are proud to announce our victory in the Engineering Design Event of the Formula Student UK Competition of 2020. We owe this success to our team members, past and present, and our sponsors, notably NRB Bearings and Mahle. This year the competition was entirely virtual, because of the COVID-19 pandemic. The pandemic has hit the process of reaching our goal in many ways, and we are tirelessly developing ways to work around it. Building a Racecar consists of several complicated steps, including ideation, design, development, and testing. Each of these steps requires tremendous amounts of collaboration from several groups of people, including judges, experts, past and present team members, critics, observers and so on.

The pandemic has primarily hit our ideation and design phases. Team communication has been the single biggest challenge that we have faced so far. Typically, the design process is a series of brainstorming sessions. And, pre-pandemic, every night from 9 pm to 12 am, we would gather in one of our lecture KDOOV LGHDWH DQG GLVFXVV QHZ PRGLĂ€FDWLRQV WR WKH FDU Doing this in a socially distant, virtual environment GHPDQGHG D VLJQLĂ€FDQW OHDUQLQJ FXUYH $GGLWLRQDOO\ making sure that all design engineers are available virtually and simultaneously, and that everyone is as productive as possible remotely, has also been a steep learning curve.

Nonetheless, we are learning to cope with the new system and have found several alternatives to get the best out of working from home. We hold regular virtual conferences, and we have all aligned our working hours to pre-pandemic ones, from 9 pm to 12 am. Everyone makes their best effort to be available on time, and these sessions have proven useful to answer questions and clear each one’s doubts. The frequency of our meetings has also increased drastically. The spread of information has also increased, allowing design engineers from one subsystem to learn more about other subsystems. Many things have contributed to creating this information super-highway in this team.

What does all this mean for our car? As a direct impact of the pandemic, we are currently designing the car for 2022 and not 2021. This extra year has allowed us to rethink every aspect of the IIT Bombay Racing racecar from design, to construction, to race day features.

Another fallout of the pandemic is knowledge sharing and documentation. However, there is a silver lining. We’ve found, that in general, more members of the team have been exposed to a broader aspect of the car, resulting in a homogenous, in-depth and structured knowledge of the vehicle across subsystems and collaboration between various subsystems of IIT-B Racing. Documentation of research and build processes has increased substantially. This documentation is needed to share knowledge between team members to enable

The pandemic and the ensuing lockdown have meant that past and current members of the team have had more time to interact and transition knowledge. ` While the pandemic has had a debilitating effect on every aspect of our lives, the IIT Bombay Racing team has found innovative ways to continue its mission to build the world’s fastest electric race car. Kudos to the effort of every team member, past and present, and the mentors for their dedication and persistence to make this happen.

onsidering how making a racecar is very handson and “heavy� in comparison to, say, making autonomous drones and is really near impossible in this terrible pandemic, right now you might be thinking “Wow! I now have a really good idea of how this pandemic has affected the IITB Racing team and how they are working through it!�. To all of you who are thinking that, great job, keep going. To those that aren’t thinking that, think about it now. To continue on your truly interesting monologue here, “But why are they even doing all this? It’s not like they have to worry about the competition during the pandemic�. And that’s where you’re wrong.

For FSUK 2020, the virtual competition involved all the teams submitting their static event presentations for evaluation to the competition followed by a live Q&A session with the judges. In usual years, since the dynamic events are given high weightage in determining team rankings, most teams focus heavily on these dynamic events. But since FSUK 2020 was held virtually, the spotlight was dramatically shifted to the static events, making them the only events important for scoring and ranking.

“At FSUK 2020, the IITB Racing team did spectacularly...” At FSUK 2020, the IITB Racing team did spectacularly, which is different from the team’s usual record in static events. Owing to the shift in focus to static events, the team prepared more than we have ever before for any static events.

Apart from the judge’s feedback that we receive in the static events, this data is often seen as the most important data they collect from the competition, because here we get to see the degree of intersection of all our theory, research, planning and design with practicality and true performance. While I’m sure all of us agree that the pandemic has been hell to live through and that the sudden shift of the way that the world works has been a real pain in the butt, the world cannot just pause and wait for things

to be comfortable once again to resume turning the gears of human society. While it has always been a part of primitive and base human nature to resist change, humans have pushed past this limiting and primitive instinct and have always adapted to situations irrespective of the odds stacked against us and making the best of it. The IITB Racing team and Formula Student are shining examples of this exact and inspiring aspect of human character.

To quote Mary Wollstonecraft Shelley “Nothing is so painful to the human mind as a great and sudden change.” This would be incomplete without including, “Nothing more joyous to the human mind than to successfully take action in the face of a challenging adversary like sudden change”.

And Zandvoort very much embodies the heart and soul of such tracks. The lack of proper run-off areas at most corners is sure to be a hit among the F1 ‘purists’. The fact that many of the corners are named after deceased historic drivers is a testament to the risks of racing and Zandvoort in particular.

AHLE GmbH is a German automotive parts manufacturer, headquartered in Stuttgart. It happens to be one of the largest companies of its kind across the globe, and its operations span across 160+ plants worldwide, manned by over 80000 employees. However, giant companies like this don’t fall from the sky. They’re built over decades with blood and sweat, and for MAHLE, it just completed ten of those decades this year. That’s right. MAHLE GmbH turns 100 in December 2020.

MILESTONE Being engineers ourselves, we couldn’t helpbut appreciate MAHLE’s achievement and decided to look at how they got to where they are now.So this is it, the story of the birth of a giant; one whose impact on modern engineering cannot be disparaged from any perspective. It all started on the 1st of December, 1920, when Hellmuth Hirth realised he needed commercial support to develop his two-stroke engines in Stuttgart. This is the day that Hermann Mahle decided to begin work with Hirth, and is considered the birthday of the MAHLE group.On the 1st of November 1922, Hermann Mahle’s brother, Ernst Mahle, joined the factory as Head of Engineering. In 1924 the company merged with Chemische Fabrik Griesheim-Elektron, the inventors of the magnesium alloy Elektron, and was renamed Elektronmetall GmbH. Its previous name, Versuchsbau Hellmuth Hirth, was retired. ,Q WKH FRPSDQ\ GHYHORSHG WKH Ă€UVW FRWUROOHG H[SDQVLRQ SLVWRQ DQG LQ WKH ZRUOG¡V Ă€UVW aluminium ring carrier piston for Diesel engines.

The company was steadily expanding, such that before WWII, it was the only company in Germany manufacturing Die-Cast magnesium alloy products. After the war, the company went into a developmental spree, creating and launching multiple new products, including Chromal surface coatings, among others. The company was privately held until 1963. This changed in the following year, as the founders decided to renounce their private ownership for SXEOLF EHQHÀW 7KH\ VHW XS D IRXQGDWLRQ FDOOHG WKH MAHLE Foundation, and relinquished their shares to the foundation. Since then, MAHLE has been consistently developing new and improved products, and today, they are SLRQHHUV IRU WKH HIÀFLHQW PRELOLW\ RI WRPRUURZ Their innovative solutions continue to set new VWDQGDUGV LQ WKH ÀHOG RI $OWHUQDWLYH 'ULYHWUDLQV DQG the optimisation of Internal Combustion engines. In the late nineties, Mahle decided to go global, and started with the USA, followed by Brazil. It chose to cooperate with international licensees, as opposed to building company-owned plants across the globe.

With the new millennium, came a host of opportunities for MAHLE. In 2003, they made their ÀUVW FRPSOHWH HQJLQH 7KH KLJK VSHHG IRXU VWURNH inline engine, with a completely novel overall structure and aluminium design. This showed the world that MAHLE now produced more engine components than any other manufacturer in the world.

I mean. We at IIT Bombay Racing make a racecar. What could we possibly have to do with a produces parts for consumer automobiles? That’s the thing. MAHLE isn’t a company that only produces parts for consumer automobiles. It does more. Way more. MAHLE has been in racing, longer than we have been breathing. About twice as long to be precise. For the past 40 years, MAHLE has been lending its expertise to the Scuderia Ferrari Formula One Team. With its industrial know-how, MAHLE Motorsport has placed an indelible mark on the history of motorsport. Not only Ferrari. In 2018, MAHLE sponsored the Rally Nova Gorica in Slovenia. This rally was combined with the Eco Rally of vehicles with new technologies. This fully resonated with MAHLE’s dual strategy Technological Advancement and Motorsport, and environmental sustainability. Information Source: MAHLE GmbH, Wikipedia.org

This is where we come in. In 2019, we inked a deal with MAHLE India for them to lend us their limitless expertise in building our racecar. We banked on our similarities in ideology, and our mutual motivation to promote technological innovation and sustainable mobility. This deal made MAHLE our Platinum Sponsor and has borne enormous dividends for the IIT Bombay Racing Team. Today, MAHLE continues to be one of the largest global automotive parts suppliers, and continues to reinforce its position in their core ICE business, while simultaneously looking towards and shaping the future of mobility.

BUT WHAT EXACTLY IS A PITSTOP? By Nikita Dipali & Srushti Bhamare

27

In the amount of you time you would have spent to

wash your hands once during 2020, Red Bull Racing team could have re-enacted their world record setting pit stop of 1.82 seconds over ten times (If this isn’t true for you, please wash your hands for a longer duration this pandemic).

In motorsports, a pitstop is a stop for refuelling, attaching new tyres, repairs, mechanical adjustments, driver change, as a penalty or any combination of these things. Although that’s quite a mouthful, that’s exactly what the team mechanics known as ‘pit crews’ do in a chaotic time span of mere seconds. As teams work harder to shave milliseconds off their cars’ lap WLPHV ZKHQ WR WDNH D SLW VWRS GHĂ€QLWHO\ SOD\V LQWR their winning strategy.

IIT BOMBAY RACING

The pits usually comprise a ‘pit lane’ and a row of garages (usually one per team) where the quick servicing is done. When called to pit, the cars enter the pit lane which runs parallel to the track, get their cars serviced and re-join the main track as the end of the pit lane as it merges into it. Beyond serving the ubiquitous need of changing into a fresh set of tyres across motorsports, there is little scope for generalising what exactly happens in a pit stop. The rules and regulations of the motorsport decide the allowed activities and even the time span for these changes. From the drivers switching for the same car in demanding Le Mans v/s the cars switching for WKH VDPH GULYHU LQ )RUPXOD ( Ă€UVW IRXU VHDVRQV regulations are designed with the safety, duration and nature of motorsport in mind. In Formula E , pit stops are almost non-existent now as no mechanical adjustments are allowed besides tyre changes. Prior to 2018, the Spark-Renault SRT 01E cars which were used did not have enough battery charge to last an entire race and drivers had to switch into a different fully charged car mid race. Thus these pit stops only required about 2 pit crew members to assist the driver with seat belts and other safety measures.

“The ‘Gen3’ will allow pit stop recharging for the first time in the championship as it is designed to handle ‘flash charging’ of up to 800kW.�

The ‘Gen3’ car to be introduced in 2022 will allow pit VWRS UHFKDUJLQJ IRU WKH Ă€UVW WLPH LQ WKH FKDPSLRQVKLS DV LW LV GHVLJQHG WR KDQGOH ψ DVK FKDUJLQJ¡ RI XS WR 800kW. And for comparison that’s over 3 times as much as the max supercharging that Tesla model X offers. Looking forward to the ‘potential’ pitstop mayhem that will bring. On a tangential note, if you haven’t checked out Formula E yet, do so for the ‘attack mode’, it is certainly worth a watch.

28

MILESTONE For the other motorsports, the strategy during the pit stop is simple. Complete the necessary adjustments in the safest, fastest manner. What then acts as a differentiating factor would be the rules of the motorsport. The most common operation of pit stops across motorsports is to replace worn tyres with a fresh set. Tyres provide traction for acceleration and is essential to nail those circuit corners. Whilst dealing with high speeds and high costs of car production like that of Formula1, it is imperative to get the traction right – to win but more importantly ‘soft’ tyres depending on the grip they can offer and the wear and tear they can sustain. In fact, Formula1 mandates at least one pit stop during a race as both tyre types must be used. Having understood this, let’s deconstruct a typical pit stop. In fact, let’s assume we are pit stop managers and need to service correctly and quickly our hypothetical racing car -IITBeLikeThat doing very well on the tracks. Our car engineers have been continuously monitoring and analysing the car data during the race and want the car to pit during the next lap for switching into a fresh set of tyres which could up our game. As a pit crew, what do we do? with all our systems and crtew members ready with their machines, positioned as close as possible to ensure no time is wasted in adjustment.

“Formula1 mandates at least one pit stop during a race as both tyre types must be used.” To change the tyres, we need to lift the car, free the lug nuts holding the tyre to the rest of the assembly were a NASCAR or a F1 race, we would be using mechanical jacks to raise our car. Well if we are an IndyCar pit crew, we would just need to activate built in pneumatic jacks using a pressurised air hose to lift it. Next we need to remove the lug nuts. We use pneumatic wheel guns to unscrew them – these guns pack quite a punch with over 3000Nm torque supply.

IIT BOMBAY RACING The second reason is the upper cap on the number of pit crew members allowed to service the car directly. With IndyCar at 6 members and NASCAR at 5 (allowed to cross the pit wall), Formula1 has nearly 20 people. This allows better work distribution and faster performance delivery by the crew.. With 8 Tyre Carriers (four for bringing in the new tyres and four for taking the old ones away), 4 Wheel Gunners, 2 Jack Men (to lift the car in the front and back), 2 Stabilisers who stabilise the car in the middle against unequal forces, 2 Front Wing Men to replace or adjust the front wing (to increase downforce by changing angle) if necessary and the Fire extinguisher the pit crew is one big cohesive family. For F1 teams, there is only one lug nut per wheel whereas for NASCAR, there are 5 per wheel. Great, we remove the worn wheels, install the fresh set and We now lower the car, quickly clean any debris on the side, adjust and tweak the aerodynamics components if necessary like the front wing and are ready to give the driver a clear go ahead. IITBeLikeThat then continues to dominate the top charts. A good day. If all motorsports have access to latest technology, why are Formula1 pit stops, that clock an average of 2.4s way faster? Two primary reasons. First unlike NASCAR and IndyCar, mid race fuelling is banned in F1 since 2010. Careful refuelling easily takes up upwards of 4 seconds and F1 would rather start out with bulkier fuel tanks.

This distribution of work has surely made pit stops keep track of actions. In 2018 Australian Grand Prix, the American team Haas had to retire both its cars Prix, Kimi Räikkönen’s Ferrari striking the tyre changer Francesco Cigarini resulting in a fractured left leg are accidents that happened due to lack of effective communication or random system errors. However, the scope for these errors has reduced 33 seconds to 2019’s 1.82 seconds, we have come a long glorious way. It is in this spirit that Formula1 is moving towards becoming a safer, more sustainable sport for the future.

“Unlike NASCAR and IndyCar, mid race fuelling is banned in F1 since 2010.” Well, the primary reason for this is safety as fuel being combustible would demand greater care in its transportation, handling and transferring. IndyCar mandates excess spilt fuel on the car to be ‘washed’ away by a water hose before the car exits the garage. The ability to refuel midway though would allow for lighter smaller and faster cars as it means an easy weight loss of 70kg per car. With the new 18 inch Pirelli tyres adding weight for all cars from 2022 onwards, it isn’t surprising to hear drivers voicing personal opinions opposing the ban.

INNOVATION KNOWS NO BOUNDARIES

Yash Mitkari

Mankind has traveled a long way from the

neolithic era to the modern era, from foot to wheel to even air and water. While I do say this, we must also understand that none of these innovations in commute came about independently and in an isolated form, rather they grew and developed from one another, borrowing phenomenal pieces of technology from each other. And to say that the automobile industry has been devoid of innovations from other transport industries would be to sin. So let’s dive deeper into this and see how various technologies have shaped the 21st century automobile. First up we have the wonder material which is what makes supercars glide seamlessly on the road: Carbon Fiber. This lightweight durable material has sure got itself some (being a bit modest here!) heavy applications to its name.

Later its use in the development of the McLaren MP4/1 (which debuted in the 1981 F1 season) and it’s following victory at the British Grand Prix cemented the fact that this material is going to satiate the thirst for high-speed action and ‘reshape’ the entire automotive industry like nothing else.

MILESTONE Call me an old sport, but the thing about cars that gets me ecstatic and off of my feet is that loud and strong grunt that only a turbo engine can give, and that gets me to turbo-superchargers, or more cutely called turbo, invented by Alfred Buchi. Though this concept of getting super-extra power by reusing the exhaust gases is raving the motor industry and enthusiasts alike, this concept initially found important applications in the aviation industry (in the 1920s) which had humongous power needs in an already low-pressure environment and needed to make use of all they had. Still, The automobile industry took about half a century to miniaturize it WR ÀW LQ DQ DFWXDO FDU DQG JLYH XV WKRVH UDUH VRXQGV we pleasure.

... Who knew principles used in audio equipment could also play a role in automotive parts. Sure enough, the concept of electromagnetics found its way to one of the most fundamental parts of a car: the suspension system. And it was none other than the audio giant Bose who developed this technology of electromagnetic suspension. The way this suspension system works is that it recovers (absorbs) the vibration energy caused in the suspension by and uses it to counteract the shock generated by a bump.

Electromagnetic suspension This not only dampens the feel of a jerk but goes at lengths to neutralize the effect of the shock. A widely used concept in Maglevs, Bose’s incredible electromagnetic suspension is sure too fast for the conventional suspension systems making your ride bump-free.

“Project Sound was not just damping the roadway bumps but actively counteracting them.â€? ANS (Automatic Navigation System) If you didn’t know this earlier, be cautious because the Pentagon is watching you. Not actually, but yes, a modern innovation in the automobile industry that makes our journey so hassle-free is a derivative of the US Space Forces mapping software, the Global Positioning System (GPS or earlier: NAVSTAR GPS), and is still operated by the US Space Forces.

This system uses satellites to get a considerably precise location of your car. Four decades on and a commute without the GPS would more often than not, get us lost.

“GPS is, to this date, operated by the United States Space Force.�

But for all that it’s worth, better to be followed by ISRO than the USSF. And in that spirit, ISRO has developed an Indian Regional Navigation Satellites System, under the operational name of NavIC. It is an autonomous regional satellite navigation system, right now mapping all of India and a 1500 km region around it, to provide accurate real-time positioning and timing services. I hope the next time you see a car, you not only see a 4-wheeler, but a symphony of technologies from different industries who were never thought of as being able to incorporate in such a system so seamlessly. This is what an automobile engineer is capable of: proving that innovation can’t remain stagnant in a single industry.

What Makes a Racecar by Raj Kumar Go Faster?

The racing of cars is one of the most joyful sports,

and its recognition has grown a lot over the years. These competitions are very high paced till the very end. Therefore, the question is, what makes these racing events so thrilling? The answer is the extreme speed (350-370 km/h) of the racing cars. There are numerous key components and features involved in making a racing car go faster, including selection of materials for body parts, aerodynamics, engine etc. The materials used for making body parts plays a crucial role in enhancing the speed of racing cars. The cars experience extreme stress when they are running at these high speeds therefore, the material for making the body parts must be light in weight as well as strong. In the beginning, steel being a lightweight material with good ultimate tensile strength (270 MPa) had been implemented for making body parts which helped in mass reduction by 10-28 % and thereby resulted in enhanced speed. Steel had also been used because it is recyclable and available at a very low cost, but it oxidizes in the absence of

The next major factor which is equally important is the Aerodynamics of the car. The common aerodynamic forces like drag, lift and side force act upon a moving race car. Drag forces resist the movement of the car because of being applied in the direction of the longitudinal axis of the car. Similarly, a force that is applied in the upward direction and reduces the vertical force on the vehicle is named as Lift. The side forces arise due to lateral winds working upon the car, which pushes the car sideways. Since lateral winds are QRW VR VLJQLÀFDQW WKHUHIRUH GUDJ IRUFH UHGXFWLRQ LV the only concern from an aerodynamic point of view in early stages of car design, due to this, 90th-century cars had been shaped like cigars to reduce the drag force.

MILESTONE The engine of the car is considered to be its core that can take its speed to the next level. In the beginning from 1947-53 Formula-1 racing cars had pre voiturette engine regulations, having 4.6 L atmospheric and 1.5l supercharged engine and further advancements have been made in engines to enhance the speed over the years. In 2014 a new V6 engine (1.6 L fourstroke turbocharged 90 degree) with a dual overhead camshaft was introduced in a Formula One car which could achieve a max speed of 370 km/h (230mph). But camshaft-based engines caused more emission, and due to this the concept of free valve engines came into the picture, and they have been considered the future of engine technology. Because of being free from conventional camshafts, free valves have also been named “camless�.

“...what makes the Koenigsegg Gemera faster than some of the fastest Formula One race cars?� Recently Koenigsegg has claimed that his new car Koenigsegg Gemera can achieve 0-62 mph (100 km/h) in just 1.9 seconds and it can reach a maximum speed of 249 mph (400km/h). So, the question is what makes the Koenigsegg Gemera faster than some of the fastest Formula One race cars? Koenigsegg uses the free valve engine technology to make Koenigsegg Gemera. The engine of this car has 2.0-litre threecylinder twin-turbo free valve engine which is RSHUDWHG XVLQJ ( PHWKDQRO DQG RWKHU IXHOV ZKLFK are renewable and provide carbon-neutral emissions. In a single-cylinder, two exhaust valves are available

for each turbo. At low rpm, only one turbo is utilized because FreeValve engine permits one of the valves to stay closed and thereby allows the single turbo to spool up faster. At higher rpm, the second valve opens, and exhaust gases are sent to both turbos. “What makes a race car fast?� (and more importantly “How to make it faster?�) is a question that has enraptured a lot of people over the years. We have explored quite a few factors that are part of the answer to this question. There are quite a few more out there, and if you are interested in learning more, you will have to wait for the next one in this series.
