假如不能及时发现这些损伤,会造成发动机空中停车,危及飞行安全
本文所介绍的超声波检查 HPC 4 级叶片榫头,是一种有效杜绝安全隐患的方法

Erosion, fatigue cracking and even fracture might be found on compressor vanes frequently
If cannot be detected adequately,the damage could lead to in-flight shut down and affect the flight safety of the aircraft
The ultrasonic inspection of HPC stage 4 blade roots
