Trying something different to what is in convention may not be propitious all the time, but this is not the case with Dragonfly DF1 helicopter. Yes, this helicopter has small rocket engines on the tips of a helicopter rotor to power it and surprisingly, it works. Very well, indeed!
This ultra-light Dragonfly DF1 helicopter is powered by hydrogen peroxide-powered rocket motors, instead of conventional fixed motor attached to the body, that are manufactured by jetpack maker, Tecaeromex.
The amazing machine has voluminous fuel tanks surrounding the pilot that supply 70% hydrogen peroxide fuel to the rockets. Helicopter’s non-burning hydrogen peroxide thrusters help power the craft to stay aloft for 50 minutes at the speed of 40mph.
Its maximum aloft time is extendable with an optional extra fuel tank. Also, with a top seed of 185km/h, Dragonfly can climb at 700m/min up to a ceiling of 4000 meters. When it’s empty, the darn thing weighs merely106kg and it can carry up to 227kg, including pilot and fuel.
Hydrogen peroxide-powered rocket motors produce no pollution, are easy to fly, easier to maintain, safe (no moving parts) and more stable to its conventional counterparts. Even when it’s the same throttle lever, but there is a motorbike-like control bar added to tilt the rotor head to control the flight direction and rotation.
