Some of today’s students already are thinking about the electric airplanes of tomorrow, thanks to NASA challenge.

In response to a NASA challenge to design an all-electric propulsion general aviation airplane, these are the five ideas out of the 20 submitted by U.S. universities, that impressed the judges.
The student contest required that the vehicle would go into service in 2020 and be competitive with standard piston engine airplanes that burn aviation fuel.
Jaiwon Shin, NASA’s associate administrator for aeronautics, said:
“The research and critical thinking that went into each of these designs was very impressive. It’s clear there is a new generation of aeronautical innovators nearly ready to make their mark on the future of aviation.”
For the contest, the theoretical airplane had to seat four people, carry at least 400 pounds of extra cargo, fly at least 575 miles during a single flight, cruise at a speed of at least 150 mph and be able to take off in less than 3,000 feet under normal conditions.
Students also had to consider what kind of extra equipment airports would need to accommodate an all-electric general aviation airplane and how much that extra infrastructure might cost.
