Background

Autogyros, also commonly referred to as gyroplanes, or rotorcraft, are rotorcraft that utilize the relative airflow of a forward flight to blow the rotor into rotation to generate lift. As with helicopters, autogyros use rotors as the primary lift devices, but the sources of power to drive the rotors in rotation are different. Autogyro is required to run on the ground during take-off, and the required pulling or pushing force comes from the propeller at the front or rear of the fuselage, and the wind blown from the head-on drives the rotor to rotate, but not just like a windmill, but rather in reverse. In forward flight, the rotor disk of the autogyro leans backward, rather than forward as in a helicopter.

However, the conventional autorotation rotorcraft cannot take off or land vertically, but needs to run on the ground to enable windward blown out to drive the rotation direction of the rotor to rise or stop gradually, so that the requirement on the take-off and landing sites is met, and the restriction is high.
