Claiming the $250,000 Igor I Sikorsky prize, in the American Helicopter Society’s Igor I Sikorsky Human-Powered Helicopter Competition, is Gamera II which has broken the record of longest in-air flight time set by a man powered helicopter last year.
Kyle Gluesenkamp, the student from the University of Maryland, along with other 40 students engineered this X-shaped helicopter so smartly to keep it afloat for 50 seconds, breaking 2011’s 11.4 seconds record set out by Gamera I.
The newest record is yet to be recognized by National Aeronautic Association that is likely to happen in few weeks time.
The engineers worked harder to make helicopter’s structure 30% lighter (weighing 32KG) by installing rotors of 13 meters diameter at the end of every 18-meter arm that has been made of balsa and foam, mylar plastic, and carbon fibre.
I want to see more of these geeky project mate.
