Application of the nondestructive testing technology for old helicopt

Abstract

With the increase of service time，the increasing number of structural and sporadic failures in old helicopters has brought more challenges to maintenance quality，and the maintenance personnel cannot detect and eliminate hidden faults in time. In this article，the application of aviation non-destructive testing in the field of aviation maintenance and the characteristics and maintenance status of old helicopters are introduced，the key parts and key components of non-destructive testing for old helicopters based on the structural characteristics and usage of helicopters are explored and determined. The specific application methods for testing key parts of helicopters based on the characteristics of different non-destructive testing technologies are elaborated，and the timing of using non-destructive testing technology in the maintenance practice of old helicopters is studied. Finally，the application prospect of non-destructive testing technology in the maintenance of old helicopters is discussed.
