A heavy-duty autogyro hybrid jump-fly system with a variable pitch seesaw rotor head

Abstract

The invention provides a hybrid power jump takeoff system of a heavy type gyroplane provided with a variable pitch teeterboard type rotor head. The hybrid power jump takeoff system comprises a propelling power module and a takeoff and landing power module, wherein the propelling power module and the takeoff and landing power module are relatively independent. The propelling power module comprises a ROTEX914UL engine, an engine input connecting disc and a tail thrust propeller, wherein the ROTEX914UL engine, the engine input connecting disc and the tail thrust propeller are connected in sequence. The takeoff and landing power module comprises a high-density lithium battery, an EMRAX 207 motor, an overrun clutch and the rotor head, wherein the high-density lithium battery, the EMRAX 207 motor, the overrun clutch and the rotor head are connected in sequence. Compared with a mechanical driving structure of a conventional jump takeoff system, the structure of the hybrid power jump takeoff system is simpler and more compact; the control flow is simplified, a control mechanism is changed, close cooperation of connection and disconnection of multiple clutches is not needed in the jump takeoff process, and repeated change of a power driving path is not needed; the driving process is simple and clear in logic and easy to achieve; the weight of the gyroplane is reduced, and the effective load space is increased; and power loss caused by the complicated mechanical structure in the power driving process is avoided, and power coupling in the jump takeoff process is reduced.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and relates to a heavy-duty autogyro hybrid jump-flying system with a variable-distance seesaw rotor head. Background technique [0002] An autogyro is a rotary-wing aircraft that uses an autorotor to provide lift and a tail propeller to provide forward thrust. The structure of the rotorcraft is different from that of the helicopter. The rotor is not connected to the engine transmission system. During the flight of the rotorcraft, the rotor is rotated by the front airflow to generate lift. Because the rotor of the rotorcraft is self-rotating, it is transmitted to the fuselage. The torque is small, so the rotorcraft does not need a tail rotor. After the engine is stopped in the air, the rotor of the rotorcraft can still be in a state of autorotation, thereby ensuring a safe landing. Rotorcraft combines the characteristics of helicopters and fixed-wing aircraft, with good low-altitude, low-speed...
