NASA announces green aircraft challenge

Washington, August 2 (ANI): The NASA Innovative Partnerships Program and the Comparative Aircraft Flight Efficiency (CAFE) Foundation have announced the Green Flight Challenge, which is a flight efficiency competition for aircraft that can average at least 100 mph on a 200-mile flight while achieving greater than 200 passenger miles per gallon. The prize for the aircraft with the best performance is 1.5 million dollars. The competition is scheduled for July 2011 at the Charles M. Schulz Sonoma County Airport in Santa Rosa, California. A variety of innovative experimental aircraft using electrical, solar, bio-fuel or hybrid propulsion are expected to enter. Several major universities and aircraft builders have expressed their intention to enter teams in the challenge. To win, teams must use cutting-edge technologies in mechanical and electrical engineering, structures, aerodynamics and thermodynamics. As a national showcase of “green” technology, the challenge is expected to help advanc...
