Backpack helicopter
From Wikipedia, the free encyclopedia
A backpack helicopter or helibackpack is a helicopter motor and rotor and controls assembly that can be strapped to a person's back, so that they can walk about on the ground wearing it, and can use it to fly. Its harness, like a parachute harness should have a strap between the legs, so that the pilot does not fall out of the harness during flight.
Related are devices like a backpack helicopter which also include a seat and leg supports and are actually very small open-topped ordinary helicopters.
Several inventors have tried to make backpack helicopters, with mixed results.
In theory, a helicopter would be more efficient than a rocket pack or jetpack, possessing a greater specific impulse, and being more suited to hovering due to the smaller velocities of the propelled gases.
