军用飞机结构局部环境谱编制的工程方法

Engineering method on establishment of local environmental spectrum for military aircraft structure

简要阐述了飞机结构的腐蚀特点,给出飞机结构局部环境谱的定义。在某典型机场地面停放环境谱的基础上,综合考虑关键部位的结构形式、密封性等因素,以某型飞机机翼Ⅳ梁接头为例,对飞机结构局部环境谱编制的工程方法进行了探索。

The corrosion characteristics of aircraft structures were briefed. The definition of the local environmental spectrum on aircraft structure was given. On the basis of a typical ground parking environmental spectrum of a certain airport, and the structure features, sealing conditions and other factors of the critical locations being taken into account comprehensively, a engineering method on establishment of local environmental spectrum for military aircraft structure was probed into through the fourth beam junction in airfoil of a certain type aircraft as a sample.
