The In-situ Testing for the Wheel Hub of One Aircraft

The detected part of the wheel hub is near to the surface of putted probe. It is difficult to implement in-situ testing using longitudinal wave straight probe . The dead zone of the dual-crystal straight probe is short, and its testing sensitivity is high. The nondestructive testing can be completed for the wheel hub by the expert dual-crystal straight probe, and it is proved that the testing effect is well.
