The invention belongs to the technical field of system electrical control, and particularly relates to an aircraft fixed wheel type undercarriage sleigh folding and unfolding control device and method. Working of the hydraulic combination valve and the hydraulic pump is controlled through the retracting and releasing switch, and retracting and releasing functions of the nose landing gear sleigh, the left main landing gear sleigh and the right main landing gear sleigh of the airplane are achieved. The three sleigh folding and unfolding state indicating lamps are controlled to be turned on and turned off through microswitches at folding and unfolding locking positions of a nose landing gear sleigh, a left main landing gear sleigh and a right main landing gear sleigh of the airplane. Due to the design of the folding and unfolding operation and locking state monitoring of the landing gear sleigh, the flying safety of a driver is guaranteed advantageously.
本发明属于系统电气控制技术领域,具体涉及飞机固定轮式起落架雪橇收起与放下控制装置及方法。通过收放开关控制液压组合阀和液压泵的工作,实现飞机前起落架雪橇、左主起落架雪橇和右主起落架雪橇的收起和放下功能;通过飞机前起落架雪橇、左主起落架雪橇和右主起落架雪橇在收起和放下锁定位置的微动开关,控制三个雪橇收起和放下状态指示灯的燃亮和熄灭。对起落架雪橇收起和放下的运行和锁死状态监测的设计,使驾驶员飞行的安全性得到了有利保障。
