Students design record-breaking helicopter (w/ Video)

Aug 09, 2011 By Sean McCalley

University of Maryland students flew past a world record after the human-powered helicopter Gamera hovered more than twelve seconds inside the campus' Reckord Armory in early July.

Pilot and biology student Judy Wexler set the for longest human-powered by a woman. She also broke the national record for longest human-powered flight.

The previous national record was only four seconds. Gamera set this milestone earlier this year inside the university's Comcast Center.

A twelve-second flight was completed on July 12. Gamera had crashed the day before, forcing the engineering team to spend all night repairing the helicopter.

Professor Inderjit Chopra says Gamera is continuously modified and repaired. He knows more improvements are to come, with another flight expected within the next six months.

The goal is to win the Sikorsky Prize, a $250,000 reward given by the American Helicopter Society. In order to win, a human-powered helicopter must fly at least thirty seconds, hover at least three meters above ground, and not drift outside a ten-meter square.

Why doesn't somebody design a housefly-style vortex generator? Doesn't that work at larger scales?

i've read about this stuff. it's only interesting because of the design applications for unmanned flight. this is never going to be practical for humans. prize or no prize, i wish there would be follow up information about what engineering and design principles lessons have been learned from this that could be applied to unmanned designs.
