Check out "gyrocopters". They look kinda like helicopters, but their rotors are not connected to the engine. Instead, they use a propeller to drive the aircraft forward, and airflow drives the rotor disk.

They operate on the same basic principle as autorotation, but for normal flight rather than arresting an emergency descent.
