NASA Offers $1.5 Million For 200MPG Aircraft

coondoggie writes to mention that NASA's Green Flight Challenge is offering up to $1.5 million for an aircraft that can hit 200 passenger miles per gallon while maintaining 100 mph on a 200 mile flight. "The Challenge is intended to bring about the development and convergence of new technologies and innovations that can improve the community acceptance, efficiency, door-to-door speed, utility, environmental-friendliness, affordability and safety of future air vehicles, CAFÉ stated. Such technologies and innovations include, but are not limited to, bio-fueled propulsion, breakthroughs in batteries, motors, fuel-cells and ultra-capacitors that enable electric-powered flight, advanced high lift technologies for very short takeoff and landing distances, ultra-quiet propellers, enhanced structural efficiency by advances in material science and nano-technology and safety features such as vehicle parachutes and air-bags."

Re:$1.5M? Peanuts.

They're looking for amateurs and university projects not Boeing or Northrup to take this one up.

"Passenger miles" the catch.

Moving four passengers the 200 miles at 100 MPH on four gallons of gas would pull it off. That would be a 'raw' MPG of 50 MPG. Or, in airplane parliance, that two hour trip would consume at an average rate of 2 gph (Gallons per Hour, the normal measurement used in the aviation industry.) A two-place airplane would need to consume half as much fuel to qualify.

A Cessna 172, with four passengers, consumes somewhere between 7-10 gallons per hour. So this would be a serious improvement. There are some 'light sport' aircraft that draw near 4 GPH, but those are two-place.

Either way, still way better than requiring a raw 200 miles per gallon.
