Autogyro
Principle of operation
An autogyro is characterized by a free-spinning rotor that turns because of the passage of air through the rotor from below. The downward component of the total aerodynamic reaction of the rotor gives lift to the vehicle, sustaining it in the air. A separate propeller provides forward thrust and can be placed in a puller configuration, with the engine and propeller at the front of the fuselage, or in a pusher configuration, with the engine and propeller at the rear of the fuselage.
United Kingdom certification
