UTA Formula SAE Racecar Combustion and Electric Dr. Bob Woods Professor of Mechanical Engineering Distinguished Teaching Professor Director, Arnold E. Petsche Center for Automotive Engineering Faculty Advisor to FSAE
Outline of Presentation The FSAE competition Technology in UTA cars The 2016 UTA FSAE cars Combustion Electric Significance to Engineering Education
Formula SAE The premier intercollegiate student design competition USA Michigan USA Lincoln United Kingdom Australia Japan Brazil Italy Germany Austria Hungary Spain China India Czech Republic Russia
Concept of the Competition Hosted by the Society of Automotive Engineers Team offers a prototype racecar to a hypothetical company Judged by professionals from automotive and race companies Vehicle judged on static and dynamic events
Events Day 1 Technical Inspection: Rules compliance, Tilt test, Sound level, Brakes
Events Day 1 Design Judging, Cost Analysis, Oral Presentation
Events Day 2 Skid Pad: Measure lateral g s Acceleration: Drag race for 82 yards
Events Day 2 Autocross: Solo lap on a course with slaloms, chicanes, straight-away, sweepers, hairpins, etc.
Events Day 3 Endurance: 13 miles on an autocross-style track, 2 drivers Fuel Economy: Best combination of fuel used and time
Scoring Points are awarded for each event. Highest points wins. UTA has won 8 times in the USA plus wins in England, Australia, and Japan. UTA quite often wins the Texas Autocross Weekend that we host on campus in the summers, and the Sports Car Club of America s Solo Nationals. In 2014 UTA was ranked number one in the USA and fifth in the world.

2016 Electric Performance Combustion cars launch at 1 g with about 0.5 g s at 60 mph. Zero-to-sixty in 3.7 seconds. Electric car is four-wheel drive. It will launch at 1.4 g s and hold 1.4g s until 50 mph. Zero-to-sixty in 2.2 seconds. Torque vectoring in braking and accelerating in and out of corners.
Significance of FSAE to Engineering Education Team is conducted as a volunteer organization with students ranging from freshmen to graduate students Seniors and graduate students could get course credit UTA offers a Certificate in Automotive Engineering at the undergraduate and graduate levels Student team spends a total of 6,000 man-hours to build and compete with a new car, mostly without course credit
Importance of Student Design Competitions To the Student: Work in a group, within a budget, within a schedule Depend upon others Engineering education Professional development, networking No 85% Job recruitment To the University: Engineering education Publicity, visibility, recognition Student recruitment Sponsorship, interaction with industry
Value of Formula SAE Develops technical skills through hands-on involvement Develops professionalism, team work, budgeting, deadlines, and other skills valuable to industry Competition-based learning is the highest form of education
