Human-powered helicopter wins Sikorsky prize

A Canadian built human-powered helicopter becomes the first machine to ever win the 33-year old Sikorsky engineering prize.

33 years ago, the American Helicopter Society launched its Igor Sikorsky engineering prize for human-powered helicopters. The prize, which comes with a check for $250,000 has never been won until this week, when a team from the University of Toronto claimed it with their invention.

To win the prize, your challenge is to build a flying machine that can get 3 meters off the ground, manage sustained flight for 30 seconds using human muscle-power alone, and stay within a 10 by 10 meter area.  “It was long seen as impossible to win this,” said Mike Hirschberg, the international executive director of the AHS.

The winning machine, called Atlas, was designed by a team of 20 students and young professionals. The machine’s design makes it extremely light, weighing only 55 kg, but having a whopping span of 49.4 m (only 10 m short of the wingspan on a Boeing 747). “This is not about creating a practical machine,” said Hirschberg, “this is to set a challenge for young engineers, to harness their creativity and technical skills and to experience working as a team against really, extremely challenging requirements.”

The Atlas was piloted by team leader Todd Reichert, 31, an aerodynamics expert. Kudos to him, because the craft requires a fairly strong pedaler who can sustain about one horsepower for the entire length of time. Of course, he had plenty of motivation; the prize is a pretty big paycheck. “We are not rich but it will enable us and the students with us to continue doing what we love doing,”
