Dragonfly Rocket Helicopter
Helicopter with Rocket-Powered Rotors [Video]

The Dragonfly helicopter uses two small rocket engines on the rotor tips, replacing the conventional engine-powered rotor. The rocket-powered helicopter is made by Swisscopter USA in Tucson, with plans to bring it to the market later this year.

The hydrogen peroxide-powered rocket motors power this ultralight craft, and they're built by jetpack maker Tecaeromex. Thanks to the voluminous fuel tanks surrounding the pilot, the helicopter's non-burning hydrogen peroxide thrusters can power the craft for 50 minutes at 40mph.
