We’re building a human-powered helicopter (HPH) to capture the
Sikorsky Prize: a monumental challenge that represents a historical aviation
first.

In order to achieve these goals, we created AeroVelo, a team of engineering
professionals and students with a common vision for lightweight and efficient
design. We hope to instill this philosophy in the education of the next
generation of engineering students and designers. Together, we hope to show the
world what is possible when we envision simple and innovative solutions to
long-standing challenges. The Sikorsky Prize: An historical world first

In 1980, the American Helicopter Society (AHS) put up a prize for the first HPH
to hover for one-minute and reach a height of 3 meters above the ground. Over
the last 30 years many international teams have taken on the challenge. A few
teams have briefly lifted off the ground, but the prize remains unclaimed.
