As an important task of aviation equipment support work,aviation in-situ testing technology can achieve efficient and convenient testing of various aspects of aviation equipment performance,timely e-valuate the damage situation of in-service equipment,and avoid equipment damage caused by improper in-stallation and disassembly.Using in-situ non-destructive testing technology to inspect aviation equipment such as aircraft engines can not only shorten maintenance time,save maintenance costs,improve mainte-nance efficiency,but also improve the service life of aviation equipment,extend service time,and provide an effective way for the reliable operation of aviation equipment.
