民用飞机主起落架舱一般处于机身下部、机身气密区以外,安装有大量的系统设备,除经受气动载荷影响外,还受到其它环境的影响,例如湿热环境、冲击环境、腐蚀环境等。因此,主起落架舱内部的表面防护就显得尤为重要。本文介绍了主起落架舱表面防护的常用技术,并针对不同的选材结构进行了具体的表面防护分析。
Civil aircraft main landing gear cabin is generally in the fuselage lower fuselage outside the airtight area, the installation of a large number of system equipment, in addition to the impact of aerodynamic load, but also by other environmental effects, such as hot and humid environment, impact environment, corrosive environment . Therefore, the surface protection inside the main landing gear becomes even more important. This paper introduces the common technology of the surface protection of the main landing gear cabin, and carries out specific surface protection analysis for different material selection structures.
