Human powered helicopter
From Wikipedia, the free encyclopedia
A human-powered helicopter is a helicopter designed to carry at least one person but limited to using only what power is provided by the person(s) on board, usually by pedalling. A high power-to-weight ratio is needed, such aircraft must be light and must have efficient rotors. Efficiency here means that the rotors must generate great lift but little drag, because drag consumes power.
The Sikorsky Prize will be awarded to the first team to reach an altitude of 3 meters for 60 seconds.
On 10th December 1989 the first human-powered helicopter, the California Polytechnic State University Da Vinci III, flew for 7.1 secs and reached a height of 20 cm.[1]
