Technical Field

The invention relates to the technical field of autorotation gyroplanes, in particular to a prewhirl control system of an autorotation gyroplane.

Background

The autorotation gyroplane is a rotor type aircraft taking an autorotation rotor as a lifting surface, the rotor does not need a power device for driving, in the process of advancing, a power system at the tail part provides thrust, under the blowing of incoming flow, the rotor autorotates and obtains energy from the air, and the lifting force for maintaining the stable flight of the autorotation gyroplane is generated.

When the autorotation rotorcraft takes off, if a rotor system does not rotate in advance, the autorotation rotorcraft can take off only by a long running distance, and the requirements on flight technology are high. Therefore, the autorotation rotorcraft generally needs to carry out prerotation control on a rotor system so as to shorten the takeoff and running distance and provide flight safety.

The existing prewhirl system of the autorotation gyroplane is divided into two types according to power sources: one is a mechanical prerotation system which uses a transmission shaft to transmit power by means of engine output power, and the other is an electric prerotation system which uses a planetary gear to reduce speed and uses a synchronous pulley to transmit power by means of motor output power. The mechanical prerotation system needs to control a control lever, a prerotation switch, an engine accelerator, braking and the like at the same time during prerotation, is complex to operate and has high technical requirements on takeoff operation of pilots. Compared with a mechanical prerotation system, the electric prerotation system simplifies the takeoff operation process of pilots, but is independent of other systems of the electric autorotation gyroplane, and directly runs to takeoff after prerotation is finished, so that the electric prerotation system is damaged, the running distance is increased, and safety accidents are easy to occur.
