Canadian engineers make history with first human-powered helicopter
NEW YORK - Engineers at the University of Toronto have won a prize that has been unclaimed for 33 years by building the world’s first helicopter powered only by human muscle.
The Igor I Sikorsky Human Powered Helicopter Competition was launched in 1980 by the American Helicopter Society (AHS). The rules stated that the US$250,000 (S$316,000) prize could only be won by a human-powered machine capable of hovering for at least 60 seconds, reach at least 3 metres in height, and stay within an area 10 metres by 10 metres.
On Thursday, the award was handed over to the AeroVelo project, led by Todd Reichert and Cameron Robertson. Their winning flying machine, called Atlas, has a set of 20-metre rotors at each corner of a square frame 50 metres on each side, and is powered by a bicycle at the centre of the square.
