An aircraft that is supported in flight by unpowered rotating horizontal wings (or blades); forward propulsion is provided by a conventional propeller.

An autocopter (autogyro) is a type of rotary wing aircraft supported in flight by lift provided by a rotor. Unlike a helicopter, the rotor of an autogyro is driven by aerodynamic forces alone once it is in flight, and thrust is provided by an engine-powered propeller similar to that of a fixed-wing aircraft. The autogyro is a distinct type of aircraft and not a hybrid between fixed-wing aircraft and helicopters.
