A STUDY OF ULTRASONICS FOR FLAW DETECTION IN TURBOJET ENGINES

Abstract

Ultrasonic inspection methods are presented for compressor blades of turbojet engines. The main emphasis was placed on the development of transducers for the inspection of the compressor blades of the J-79 and J-71 engines. Much of the work done was concerned with the development of a usable surface wave standardization system. A unique type of calibration block was developed making possible the accurate calibration of transducers and the calibration of the reject level and gain settings of the pulse-echo system.
