The property of a rotor system to maintain its angular velocity without engine power, the relative force provided by the forward component of the lift forces, acting on the rotor blades.

CONT

Most [constant-speed propellers]... also provide for full "feathering" of the blades in flight to prevent "autorotation" or "windmilling" of the propeller, thus reducing drag when the engine is dead.
