Failure Analysis of Unexpected Opening of the Main Landing Gear Door of Aircraft

主起落架舱门是起落架系统的重要组成部件,当舱门收放存在故障时,系统处于失效状态,将不能起到收放作用。本文对某型飞机主起落架舱门收放原理和故障原因进行了分析,深入研究上位锁的控制过程和逻辑,提高了对起落架舱门收放系统的认识和理解。

The main landing gear door is an important component of the landing gear system. When there is a fault in the cabin retraction, the system is in a failure state and it will not be able to play a retractable role. This paper analyzes the principles of retracting and releasing of the main landing gear of a cartain aircraft, analyzes the control process and logic of the upper lock in depth, and improves the understanding of the landing gear cabin retractable system.
