Bicycle Helicopter Hovers Closer to Reality
A while back we posted on a pedal-powered helicopter concept built on a fat bike base.
Now, the concept gets a less bicycle-looking form factor but actually flies. Students from the University of Maryland are chasing the Sikorsky Prize, one pedal stroke at a time. They’re doing it aboard a pedal-powered helicoptor made of carbon fiber, styrofoam and string. It has a 100ft span and weighs just 80 pounds without the rider. All they have to do to win the $250,000 prize (unclaimed for more than 30 years) is hover for one minute, top 10 feet and not drift more than 10 feet horizontally.
The video tells the story and plenty of background from NPR is here.
