Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] see figure 1 , the wing folding controller of the present invention includes a 24V DC stabilized power supply, a three-position four-way electromagnetic reversing valve, a two-position four-way reversing valve, a stop valve, a manual / automatic knob switch, a folding / stopping / unfolding knob switch, and a counter and two solid state relays. Wherein, the signal input terminal of the 24V DC regulated power supply is also provided with insurance. The stop valve is connected to the 24V DC regulated power supply at the signal input end, and the stop valve is connected to the two-position four-way electromagnetic reversing valve through the control switch, and the two-position four-way electromagnetic reversing valve controls the aircraft wing through the three-position four-way reversing valve. double-acting actuator. The manual / automatic knob switch connected to the 24V...

Abstract

The invention belongs to the technology of aircraft wing folding, and relates to a wing folding control instrument. The wing folding control instrument comprises a 24 V direct-current stabilized-voltage power supply, a three-position four-way electromagnetic directional valve, a two-position four-way electromagnetic directional valve and a stop valve, wherein the stop valve is connected with the 24 V direct-current stabilized-voltage power supply at the signal input end and connected with the two-position four-way electromagnetic directional valve through a control switch; and the two-position four-way electromagnetic directional valve is used for controlling a double-action actuating cylinder of an aircraft wing through the three-position four-way electromagnetic directional valve. The wing folding control instrument can be used for effectively controlling the motion state of the double-action actuating cylinder in the wing, is flexible and convenient to mount and simple to operate, and can reflect the wing folding frequency so as to solve the problem of wing folding control.

Description

technical field [0001] The invention belongs to the aircraft wing folding technology, and relates to a wing folding controller. Background technique [0002] In the wing folding function test, it is necessary to control the double-acting actuator in the wing, so as to control the action of wing folding / flattening / stopping. [0003] As the wing folding technology has not yet been carried out in China, and the foreign technology blockade is serious, it is difficult to obtain detailed information. Contents of the invention [0004] The purpose of the present invention is to provide a wing that is connected with a double-acting actuator in the wing, can flexibly control the folding / flattening / stopping of the wing, and effectively improve the controllability and reliability of the test. Folding controller. [0005] The technical solution of the present invention is: a wing folding controller, which includes a 24V DC stabilized power supply, a three-position four-way electroma...
