Problems solved by technology

The use of rudder wing attitude control is a very important method of aircraft attitude control. Many existing aircraft use air rudders for simple attitude control, but this method only relies on air to provide power, and the efficiency is very low. Disadvantages such as slow speed and being affected by flight altitude

Embodiment 1

[0051] The gas rudder and air rudder linkage mechanism of the aircraft in this embodiment includes a ball screw transmission mechanism, a gas rudder deflection mechanism, and an air rudder deflection mechanism. The ball screw transmission mechanism includes servo motor 5, coupling 6, screw 7, screw nut 8, motor fixing frame 4, screw support frame 9, and the gas rudder deflection mechanism includes actuating rod 10, cam 11, gas rudder Sheet 12, gas rudder support 14, locking nail 13, air rudder deflection mechanism includes piston pin 16, piston barrel 15, air rudder plate 17.

[0052] The motor rotor rotates counterclockwise (looking backward from the position of the servo motor 5), the motor rotor drives the lead screw 7 to rotate counterclockwise through the coupling 6, and the counterclockwise rotation of the lead screw 7 is converted into the backward linear motion of the lead screw nut 8, The backward linear motion of the lead screw nut 8 respectively drives the backward ...

Abstract

The invention discloses a jet vane and an air vane linkage mechanism of an aircraft. The linkage mechanism comprises a combustion chamber, an exhaust pipe, an exhaust pipe cover, a ball screw drive mechanism, a jet vane deflection mechanism and an air vane deflection mechanism, a servo motor rotor is connected with a lead screw through a coupling, the lead screw drives a lead screw nut to conduct linear motion in a rotary mode, so that an actuating rod and a piston actuator controls the jet vane and the air vane to conduct linkage deflection, and the deflection angles close to the same; and a motor fixing frame and a screw support frame are overlapped and fixed through the arc surface and the inner surface of the exhaust pipe cover, and the lead screw nut and the air vane are cooperatively transmitted through a cylinder bore piston structure. According to the jet vane and the air vane linkage mechanism of the aircraft, the structure is simple, mechanical transmission is stable, vane pieces are of cross-shaped layout, a steering engine can control the vane pieces to deflect flexibly, the jet vane and the air vane conduct linkage deflection, the efficiency of aircraft handling is improved greatly, four independent groups of the jet vanes and the air vanes are in linkage so that the flight attitude of the aircraft can be adjusted quickly, and the mobility of the aircraft can be improved greatly.

Description

technical field [0001] The invention belongs to the technical field of aircraft attitude control, in particular to an aircraft gas rudder and air rudder linkage mechanism. Background technique [0002] In today's world, various aircraft emerge in an endless stream, and these aircrafts always cannot do without their own attitude control system when flying in the air or outer space according to the predetermined trajectory. The use of rudder wing attitude control is a very important method of aircraft attitude control. Many existing aircraft use air rudders for simple attitude control, but this method only relies on air to provide power, and the efficiency is very low. Disadvantages such as slow speed and being affected by flight altitude. Contents of the invention [0003] The object of the present invention is to provide a linkage mechanism of an air rudder with aerodynamic control and a gas rudder with thrust vector control, and simultaneously control the deflection angl...
