10 MW RING MOTOR OSU-NNX14AL87A CODRIN-GRUIE (CG) CANTEMIR RESEARCH SCIENTIST CENTER FOR AUTOMOTIVE RESEARCH

This work was sponsored by NASA under the hybrid gas / electric propulsion subproject of the advanced air transport technology project, previously known as the fundamental aeronautics program fixed wing project.

The purpose of this project is to significantly reduce the thrust specific fuel/energy consumption.

TARGET: CFM-56 The target is a 60 percent reduction relative to a baseline Boeing 737-800 aircraft with CFM56-7B engines in the 2030 to 2035 time frame.

WHY US?

• The study suggests 13 MW at 5400 rpm (max N1) for a total weight under 700 kg (1540 lbs).

• This is already 11.2 hp / lbs some 40% better than required • However, there are 2-3 major issues which were revealed only towards the end of the study

PROJECT GOALS

• Direct driving of the LP shaft with no gears 10 MW continuously at 5000 rpm (20000 Nm continuous torque) 8 hp/lb

• No permanent magnets An induction motor will be way more forgiving in case of failure while flying

• No nacelle distortion

HOW? By marrying 3 new technologies in the same machine with the accent on fabrication and integration while optimization has only a marginal role

•Ring VCSWC or Variable Cross-Section Wet Coils (2 new technologies) •Cooling •Efficiency •Power Density

•Distributed Power Electronic (new technology) •Cooling •Power Level •Control

VARIABLE CROSS-SECTION TECHNOLOGY PATENT PENDING

• Ring Motor • Ring Coils • Reversed construction

VCS UNFOLDED

Just for the sake of facilitating intuition, the coil depicted is only formed in the first slot (with 4 turns) and unformed for the remaining 4 turns (which should fit in the adjacent slot).

As shown, in order to form the coil, the winding process commences in the middle.

Technologically the conductor is no longer of a wire type but moreover is a ribbon with some material removed for the portions of the coil located in the slot (it can be water or laser cut from a sheet). As visually presented, the last turns have a higher length outside of the slot obviously the increased cross section has subsequently a major impact in increasing the overall efficiency. In this specific design, the total stator resistance can be decreased 60% over conventional coils.

ROUTES TESTED • There are 2 routes for which the various simulation and optimization studies are performed: • Route 15 • Route 19

• Route 15 is an urban route and has the following features: • Stop sign/s: 1 • Traffic lights: 14 • Length: ~7.5 km

• Route 19 is a mixed route and has the following features: • Stop sign/s: 1 • Traffic lights: 5 • Length: ~7 km 132

INTELLIGENT DRIVER MODEL : BASELINE • The Intelligent Driver Model (IDM) is a deterministic car-following model for one-lane situations: • In such models, the decision of the driver to accelerate or to brake depends only on his/her own speed, and on the position and speed of the "leading vehicle" immediately ahead. • Model parameters describe the driving style, i.e. the “aggressivenessâ€? of the simulated driver.

• The IDM model equations read as follows: Standard Formulation

INTELLIGENT DRIVER MODEL : RESULTS Results : • A full-factorial Design of Experiment (DOE) was performed to analyze the impact of the IDM model parameters on the travel time (TT) and fuel consumption (FC) for Route 19 and Route 15; • To compare the fuel consumption and travel time of a real-world driver, IDM was calibrated with driving data and the FC, TT values were compared with the DOE data as shown below: Route 19

Route 15

• It is seen that the the points obtained from the calibration with the driving data are closer to DOE curve.

• From this analysis, an averaged driver behavior can be extracted which can further be used to benchmark the fuel economy for connected and automated driving.

First Robotics High School Student Team

Camp CAR

The Motorsports Garage also hosts a variety of K-12 STEM outreach programs

CAR Internship Program

CARâ&#x20AC;&#x2122;s integrated, immersive environment enables MS and PhD students to apply their research in the competition vehicles, while undergrad team members are exposed to a wide range of mobility R&D. Tomorrowâ&#x20AC;&#x2122;s talent is developed here.

If you (help us) build itâ&#x20AC;¦

We will develop and deliver more talent, more leaders and more innovation to you

A new, larger facility would mean more students gaining both knowledge and experience prior to entering the workforce.

New space

Current CAR facility with new facade

â&#x20AC;&#x153;The Ohio State Motorsports program has given me the unique opportunity of receiving hands-on engineering experience, connections to industry and leadership opportunities as I pursue a career in the automotive industry. A new facility would showcase the talent, hard work and accomplishments of the students on these teams, while giving them access to more space, equipment and room to grow.

They will be equipped with the right tools to tackle the challenges of their projects, and will be able to directly transfer their skills to solving problems that face the industry.â&#x20AC;?

Polina Brodsky Buckeye Current team member CAR Graduate associate

A new Motorsports Facility creates additional space for research facilities.

Part of the project plan includes renovating the old Motorsports building to expend our physical facilities including: 1. Additional office space for graduate students (~20 seats) 2. Expanded garage space for vehicle programs 3. Additional space for high-voltage and other safety-sensitive projects

LO OR NO EMISSION BUS TESTING PROJECT OVERVIEW Walt Dudek Manager Engineering Services

FEDERAL TRANSIT ADMINISTRATION LOW AND NO EMISSION OVERVIEW FTA LoNo Program • Provides funding to state and local governmental authorities for the purchase or lease of zero-emission and lowemission transit buses • Support transit infrastructure including the acquisition, construction, and leasing of required supporting facilities • FY13-18 FTA Bus Grants totaled $271MM • Under the FAST Act, $55MM per year is available until FY20 • There are currently 1,500 Zero emissions transit busses on order in the US

OHIO STATE’S FTA PROGRAMS Ohio State supports the FTA Low and No Emissions initiative through two programs: Bus Testing and Component Testing. Both programs produce public data to support the adoption of new low and no emissions transit busses and the integration of new component technologies into existing fleets.

Low and No-Emission Bus Testing (LoNo-Bus) • Required testing for any buses acquired with FTA funding to provide public transportation service (49 CFR Part 665) • Full vehicle testing with a pass/fail criteria • Ohio State selected as a test center in 2018 Low and No-Emission Component Assessment Program (LoNo-CAP) • Voluntary program to promote the development and adaptation of new components and technologies intended to allow existing transit fleets to make more low and no emission improvements • Component, System, or full vehicle testing options • Test program content directed by industry and Ohio State

FTA IMPACT AT OHIO STATE Attracting both US and foreign manufacturers to Ohio for…

• Research, Development, FTA Certification, Yearly Industry Technology Interchanges

Creation of an on-campus bus testing center • Scaled for the needs of the transit bus and commercial vehicle industry.

• Focused on Low and No Emissions Technologies from research and development through testing and certification

Significant new funding opportunities • FTA Research opportunities for Bus Testing Program • OEM Manufacturer Research Funding for 20% bus testing cost share requirements • New Research and Development activities at OSU and TRC to support manufacturer product development Addition of new refueling infrastructure for electric and hydrogen vehicles • Supporting the Ohio State Bus Test Center and future OSU/Columbus/Public fleet needs

EXPANSION OF CAPABILITIES

Expansion of Ohio State and TRC’s Heavy-Duty Research Capabilities Ohio State’s test capacity will be enhanced and expanded to include…

• Energy or fuel economy testing for electric vehicles, liquid, and gaseous fuels • Emissions certification testing • Individual system and component benchmarking for LoNo technologies including energy storage, hydrogen fuel systems, DC:DC converters, HVAC, and electric chargers

• Full life durability testing including braking, noise, towing, structural integrity, hoisting, and repair time tracking • Performance testing including acceleration, gradeability, and top speed
