文档介绍：飞机起落架故障分析
【摘要】
起落架是飞机的重要组成部分,飞机的停放、起飞着陆主要是由起落架来完成的。所以起落架的工作性能直接影响了飞机的安全性和机动性。
飞机起落架故障很多,本文主要针对歼七和歼八飞机的一些故障加以分析。主要阐述了歼八飞机主起落架机轮半轴裂纹故障分析和歼七飞机起落架收放系统典型故障分析。
关键词: 起落架机轮半轴裂纹法兰盘自动收起油路堵死电液换向阀
Abstract:
Landing gear is an important part of the plane, the plane's parking, off and landing is posed of landing gear to finish. So the landing gear on the working performance directly affect the safety of the aircraft and mobility.
Landing gear fault many, this article mainly aims at annihilates seven and fighters eight aircraft some fault analysis. Mainly expounds the main annihilates eight plane aeroplane undercarriage tyre half axle crack fault analysis and fighters seven aircraft gear fault analysis of typical positioning systems. And explained how to judge whether these faults and some trouble-shooting reason method.

飞机座舱的结构密封
【摘要】
舱门密封设计是飞机密封舱设计的重要组成部分,密封舱性能的好坏关系着飞机的飞行安全,因而舱门密封设计需要得到足够重视。舱门密封性能的影响因素很多,本文对影响结构密封性能的主要因素进行分析讨论,给出结构密封性能验证思路。
Abstract: Design of the aircraft hatch seal is one of the most important parts of aircraft sealed cabin. The property of the aircraft hatch seal is relative to the airplane safety, so the design should be paid enough attention. There are many factors that affect the property of the aircraft hatch seal. In this study, the main effecting factors on structural sealing property are analyzed and discussed, and a testable method for the structural sealing property is presented.
