Aircraft empennage regulation mechanism with pitching and yawing completely decoupled

Abstract

The invention discloses an aircraft empennage regulation mechanism with pitching and yawing completely decoupled. The aircraft empennage regulation mechanism comprises an empennage fixing part, an empennage pitching part and an empennage yawing part, wherein the empennage fixing part, the empennage pitching part and the empennage yawing part are sequentially arranged on the aircraft tail from front to back, the empennage fixing part and the empennage pitching part are hinged, and the empennage pitching part and the empennage yawing part are hinged. The aircraft empennage regulation mechanism further comprises a pitching steering engine and a yawing steering engine, wherein the pitching steering engine and the yawing steering engine are arranged on an aircraft body. The pitching steering engine rotates to drive a connecting rod to move to drive the empennage pitching part to swing around the axis of a pitching rotation shaft. The yawing steering engine rotates to pull two traction ropes to move to drive the empennage yawing part to swing around the axis of a yawing rotation shaft. According to the invention, the structure style of arranging a drive steering engine on the aircraft tail traditionally is abandoned, and the weight of the aircraft tail is effectively lowered. In addition, compared with a traditional kinematic coupling empennage regulation mechanism, the aircraft empennage regulation mechanism can regulate empennages through mechanical decoupling, and the reliability, the stability and the regulation accuracy of a system are greatly improved.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a tail adjusting mechanism of a bionic flying robot. Background technique [0002] Due to the relatively mature technology, fixed-wing aircraft and multi-rotor aircraft have been initially and widely used in the fields of disaster rescue, environmental detection, and air cruise. [0003] Among them, fixed-wing aircraft generally adopt the method of horizontal take-off and landing, relying on the lift generated by the fixed-wing for take-off, landing and cruising. , The requirements for take-off and landing runways are also high, which limits its wide application. [0004] The multi-rotor aircraft relies on the rotor to generate lift, can perform vertical take-off and landing, and has low requirements for the take-off and landing environment. In addition to vertical take-off and landing, the multi-rotor aircraft can also control the flight attitude by distributing the lift of e...

Problems solved by technology

[0006] The tail adjustment mechanisms of existing bionic flying robots are mostly coupled with pitch and yaw, and the decoupling is realized through the calculation of the control system, which will bring disadvantages such as low decoupling efficiency, low precision, and slow response speed; and the current Part of the decoupled pitch and yaw motion tail adjustment mechanisms are all in series layout, and the steering gear is placed on the movement mechanism at the tail of the aircraft, which increases the weight of the tail of the aircraft and makes the tail of the aircraft more bloated and bulky
