随着民航飞行学院洛阳分院西锐SR-20飞机不断地运用与飞行教学,飞行小时的不断累积,西锐SR-20飞机所用的大陆发动机也要进行到寿翻修工作,该发动机上的曲轴在翻修过程中也要进行相关的无损检测工作。本文探讨研究了如何对大陆发动机的曲轴进行有效的无损探伤,运用何种无损检测方法对其进行检查,确保其正常运转、保障飞行安全。 With the continuous use of flight instruction and flight hours of the Xirui SR-20 aircraft of Luoyang Branch of Civil Aviation Flight Academy, the mainland engine used in the Xirui SR-20 aircraft will also undergo renovations to its service life. The crankshaft on the engine at The renovation process should also be related to non-destructive testing. This paper explores how to conduct effective non-destructive testing on the crankshaft of a mainland engine, what non-destructive testing method is used to inspect it, ensure its normal operation and ensure flight safety.
