Team Tennessee. Year 4


At the University of Tennessee Challenge X is a capstone senior design project for seniors in mechanical engineering and occasionally for electrical and computer engineering students. This means that each year there is an entirely new team. The team is lead by graduate student team leaders under the guidance of a faculty advisor.


Faculty Advisor

Dr. David 'Butch' Irick

Professor of Mechanical Engineering

Dr. Irick's research interests are, Automotive testing for emissions and performance. Hybrid electric vehicle design and system integration. The use of alternative fuels (methanol, ethanol, natural gas, bio-diesel) in vehicles. Computer integrated engineering and manufacturing.
