Problems solved by technology

[0004] At present, the main disadvantages of the traditional elevator adjustment mechanism and elevator trim control system are as follows: ①The electrical control of the effect adjustment mechanism and the adjustment plate control system is designed separately, the electrical control design is complicated, there are many circuits, and the weight is large
②Unable to realize left / right driving operation priority interlocking, which is not conducive to system operation

Embodiment Construction

[0019] The elevator trim control circuit of a kind of aircraft of the present invention is described in detail in conjunction with accompanying drawing:

[0020] The integrated design of the elevator trim control circuit is as follows: when the transfer switch 1 is operated, the relay B5 works to realize the work switching of the trimming mechanism / adjustment plate system.

[0021] The trim authority of the left drive is higher than that of the right drive. The design is: when the left drive trim switch (up and down) is operated 3, the relay A2 works, and the power of the right drive trim switch 6 is cut off. At this time, the right drive trim is operated at the same time. Switch 6 does not change the movement direction of the trim mechanism.

[0022] The integrated design of the electric control system of the adjustment mechanism and the adjustment plate control system is as follows: figure 1 , 2 As shown, it includes 1. Adjusting mechanism / adjustment plate changeover switc...

Abstract

The invention belongs to the technical field of aviation, and particularly relates to an elevator balancing control circuit of an aircraft. The elevator balancing control circuit comprises a conversion switch, a left driver balancing switch, a right driver balancing switch, a relay B, two sets of relays A, an effect regulating mechanism and an adjusting sheet electric mechanism. An integrated design is adopted for the electrical control design of the effect adjusting mechanism and the adjusting sheet control system, the conversion control between the systems is realized through the conversionswitch, the electrical control is simple, the number of lines is small, and the weight is light. Through the control of the relay, the left driving balancing authority can be higher than the right driving balancing authority, and the system is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of aviation, and relates to an aircraft control rod trim system, which realizes the manual trim function of the aircraft control rod force, and is mainly applied to large and medium-sized transport aircraft and civil aircraft. Specifically, it is an elevator trim control circuit of an aircraft. Background technique [0002] In an irreversible power-assisted control system of an aircraft, the manual trimming mode of the elevator adjustment mechanism is used to trim the control force generated by the driver manipulating the joystick to compress the elevator spring load mechanism, so as to reduce the driver's work fatigue. [0003] When the flight control hydraulic system and the left general hydraulic system of the flight control booster fail at the same time or the flight control hydraulic system and the right general hydraulic system fail at the same time, the elevator trimmer control system is put into use ...
