Student-built electric car sets land speed record at Salt Flats
(麻豆淫院Org.com) -- An electric car designed and built by BYU engineering students set a world land speed record for its weight class, averaging 155.8 mph over its two required qualifying runs, one of which was clocked at 175 mph.
The milestone marks the end of a seven-year quest of more than 130 students, led by Perry Carter, who just retired as an associate professor.
鈥淭his is a wonderful closure to 31 years of teaching at BYU and many projects,鈥� Carter said after the record was certified. 鈥淏ut this is the one that takes the cake. I鈥檓 done.鈥�
鈥淭his is like Christmas morning,鈥� said Jeff Baxter, a former student captain on the project who returned to Utah to witness the record-setting runs. 鈥淏ut like five Christmas mornings 鈥� or seven Christmas mornings!鈥�
In land speed racing jargon, the car is called a streamliner, meaning it has a long, slender shape and enclosed wheels to reduce air resistance. Students custom-built the lightweight carbon fiber body after modeling it on a wind tunnel program on a computer. The aerodynamic performance and lithium iron phosphate batteries helped the car reach its high speeds.
With one inch of ground clearance and an extremely wide turning radius, the streamliner can run safely only in places like the Bonneville Salt Flats. Jim Burkdoll, president of the Utah Salt Flats Racing Association, drove the car on its two record-setting runs, certified by the Southern California Timing Association - Bonneville Nationals, Inc.
The streamliner, named 鈥淓lectric Blue,鈥� competes in the 鈥淓1鈥� class, which includes cars weighing less than 1,100 pounds. Because electric cars rely on heavy batteries, engineering a speedy vehicle at such a light weight is very difficult. That鈥檚 why there were no prior certified speed runs for this class, although unofficial standards reached the 130s. The BYU team completed a qualifying run at 139 mph last year, but failed to complete the required second run when the car rolled, damaging the car鈥檚 body but not the driver鈥檚.
About half the students who have worked on the streamliner program over the years have been manufacturing engineering technology majors, about 40 percent mechanical engineering majors, and the rest from various other disciplines. Many worked on the car as part of an annual capstone course, but most were unpaid volunteers. The primary sponsor of the project is Ira A. Fulton, after whom BYU鈥檚 College of Engineering and Technology is named.
Kelly Hales is a BYU electrical engineering major who came to BYU to prepare for a career working on electric cars. He joined the streamliner team and took over as student captain of the project when Baxter completed his BYU MBA in April and left to work for a space exploration company. Baxter is one of many alumni who have gone on to success in their careers 鈥� several working on electric cars or competitive car racing 鈥� after helping develop the streamliner.
鈥淪tudents who study music need to give concerts, students who study dance need to perform, and students who study engineering need to engineer things and compete to see how they work,鈥� said Carter, the team mentor. 鈥淓xperiential education is a key aspect of every program.鈥�
