对某型飞机起落架舱门的结构特点、装配部位的关键点以及解决外蒙皮定位等几方面进行了研究,并根据该机型的结构特点及笔者的实际工作经验,对舱门协调安装的关键技术进行了论证。通过采用增加辅助修合方式、调整装配顺序等方法,实现了起落架舱门的协调安装,满足了设计及工艺要求。 The structure of the landing gear door of a certain type of aircraft, the key points of the assembly site and the positioning of the outer skin were studied. According to the structural characteristics of the aircraft and the author’s practical work experience, The key technologies were demonstrated. By adopting the methods of increasing the auxiliary repair and adjusting the assembly sequence, etc., the coordinated installation of the landing gear door has been realized, which meets the design and technological requirements.
