某型飞机起落架支柱内壁腐蚀问题分析

Corrosion Analysis of the Inner Wall of the Landing Gear Strut of a Certain Type of Aircraft

针对某型飞机多个起落架支柱外筒的内壁在定检分解检查中发现腐蚀的问题,结合故障件的理化分析结果,并通过环境模拟试验,确定了故障原因,提出了支柱外筒腐蚀问题的解决措施。

Aiming to the corrosion problem found in the inner wall of outer cylinder of several landing gear struts of a certain type of aircraft,during disassembling inspection in the aircraft periodic inspection in combination with the physicochemical analysis results of the fault components,and through the environmental simulation test,the cause of the fault is determined,and the corresponding solution is proposed.
