一种发动机叶片原位超声检测方法

Engine blade in-situ ultrasonic detection method

Abstract

An engine blade in-situ ultrasonic detection method comprises the following steps: carrying out in-situ detection of an engine blade in the outfield through using a special probe to obtain an A scanning oscillogram on an ultrasonic flaw detector, and determining whether the detected blade in the scanning area of the probe is damaged or not according to the A scanning oscillogram, wherein the special probe concretely comprises a probe body (1), a plug seat (2), a water tube (3), a cable (4) connected with the ultrasonic flaw detector, and a piezoelectric wafer (5). The method realizes the in-situ detection, and has a very prominent economic value, a huge technological application value and excellent technological effects.
