场外使用飞机时,由于设计、构造和使用、维修等因素导致经常发生场外故障,怎样结合故障情况,找出故障出现的原因,对解决飞机机体机翼故障问题以及提高使用水平发挥了巨大的意义。本文主要是对某型飞机机体机翼接头裂纹故障,飞机服役环境、机翼接头表面防腐状态、飞机机体机翼接头受力与建模全面分析,找出裂纹形成的原因,同时提出具体的解决手段。 Off-site use of aircraft, due to the design, construction and use, maintenance and other factors lead to frequent off-site failures, how to combine the failure to find out the reasons for the failure to solve the problem of aircraft fuselage failure and improve the level of use has played a huge Meaning. This paper mainly analyzes the cause of the crack formation and the concrete solution to the problem of cracks in the wing joints, the service environment of the aircraft, the anticorrosion condition of the wing joints, the force and modeling of the aircraft wing joint, means.
