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.
