RELEASE 09-178
NASA and Cafe Announce Green Aircraft Challenge

WASHINGTON - The NASA Innovative Partnerships Program and the Comparative Aircraft Flight Efficiency (CAFE) Foundation today announced the Green Flight Challenge. The contest 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. The competition is scheduled for July 2011 at the Charles M. Schulz Sonoma County Airport in Santa Rosa, Calif. 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 advance all three of the major climate mitigation initiatives: efficiency, conservation and zero-carbon energy sources. These technologies will support advances in aviation and may have broader applications in transportation and energy storage.

The Green Flight Challenge is administered for NASA by CAFE. Founded in 1981, CAFE is a non-profit organization dedicated to advancing the understanding of personal aircraft technologies through research, analysis and education.

NASA is providing the prize money as part of the Centennial Challenges program. The program seeks innovative solutions to problems of interest to NASA and the nation from diverse and unconventional sources. Competitors may not receive government funding for their entries in this challenge.
