Electromagnetic positive and negative propeller power device of electric fixed-wing aircraft

Abstract

The invention discloses an electromagnetic positive and negative propeller power device of an electric fixed-wing aircraft. The power device comprises an electromagnetic positive and negative propeller structure and a positive and negative propeller control circuit, and the electromagnetic positive and negative propeller structure comprises a variable pitch rod, a torque conversion mechanism, a hollow shaft brushless motor, a bidirectional self-holding electromagnet, a motor mounting seat and a bidirectional self-holding electromagnet mounting seat; a coupler is arranged between the variable pitch rod and the bidirectional self-holding electromagnet, a connecting double-thread screw is arranged between the electromagnet mounting seat and the motor mounting seat, the torque conversion mechanism, the hollow shaft brushless motor and the bidirectional self-holding electromagnet are coaxially arranged, and the torque conversion mechanism is arranged at the front end of a main shaft. By theadoption of the structure, under the condition that motor steering of electric fixed-wing aircrafts including electric unmanned aerial vehicles, electric aircrafts and electric aviation model aircrafts is not changed, reverse thrust deceleration, ground reversing and emergency takeoff stopping of the electric fixed-wing aircrafts can be achieved. The device is convenient to maintain and replace parts, low in cost, compact in structure, small in size, light in weight, high in reliability, easy to operate, remarkable in function, novel and practical.

Description

technical field [0001] The invention relates to the field of electric fixed-wing aircraft, in particular to an electromagnetic forward and reverse propeller power device of the electric fixed-wing aircraft. Background technique [0002] With the popularity and development of new energy aircraft such as electric drones and electric aircraft, and the wide application of electric drones in the field of military technology, the world's functional requirements for electric fixed-wing aircraft are getting higher and higher. Traditional fuel aircraft The propeller pitch change method is no longer suitable for purely electric-driven aircraft. The propeller pitch of traditional fuel aircraft is driven by hydraulic oil or lubricating oil, which has the characteristics of large size and overall weight, and is not suitable for purely electric-driven aircraft. [0003] In order to solve the above-mentioned problems, a pure electric drive electromagnetic forward and reverse propeller powe...
