An autogyro is a flying machine. Like a helicopter, it is a rotary wing aircraft- which means that it has a rotor to provide lift instead of wings like conventional airplanes. Unlike a helicopter, the rotor is not powered by the engine. It is made to spin by aerodynamic forces, through a phenomenon called autorotation. Since the rotor is not powered, an autogyro needs a separate source for propulsion, like an airplane. Conventionally, these have been propellers, but it's possible to use jet engines as well. Now what causes the rotor to spin, or "autorotate?" The simple explanation is that the wind passing through it gives it its power. Think of those seed pods that spin as they fall. As they fall, the air makes them spin. (Because they're spinning, it's as if the mini wing was moving faster, so it creates more lift, and the seed pod doesn't fall as fast as it would if it didn't spin.)
