飞机蒙皮缺陷检测的现状与展望

Current Status and Prospect of Defect Detection of Aircraft Skin

飞机蒙皮在装配中会形成接缝处间隙与阶差的不均匀,在服役过程中会产生凹痕、裂纹、腐蚀等缺陷,这些问题使蒙皮强度降低,承载能力下降,影响飞机的气动性能,危及飞行安全。针对飞机蒙皮缺陷的检测工作在飞机检修中占比很大,也是飞机安全性的重要保证。介绍了飞机蒙皮常见的7种缺陷,并分析了其产生的原因、位置以及危害;根据缺陷所产生的位置,将其分为三大类,系统地阐述了针对蒙皮缺陷的各类检测技术的发展现状;对飞机蒙皮检测技术的现状进行总结,并对蒙皮缺陷检测的发展前景进行了展望。

In the process of aircraft assembly,uneven gaps and steps will be formed at the seams of the aircraft skin.In addition,dents,cracks,corrosion and other defects will be produced in the skin during the service process.Due to these defects,the strength of the skin will be weakened and the carrying capacity will be reduced,which will eventually affect the aerodynamic performance of aircraft and endanger flight safety.The detection of aircraft skin defects accounted for a large proportion in aircraft maintenance,consequently it is crucial for aircraft safety.This paper introduced seven common defects of aircraft skin,and analyzed the causes,locations and hazards of these defects.On the basis of the location of these defects,the defects were divided into three categories,and the development status of various kinds of detection technology of skin defects was systematically described.The status quo of aircraft skin detection technology was summarized,and the development prospect of skin defect detection was prospected.
