Abstract:

This report describes the work conducted on a program to design, fabricate and evaluate a prototype Computer Automated Ultrasonic Inspection System for inspecting complex aircraft forgings. This report documents the modification required to off-the-shelf ultrasonic equipment to provide all the ultrasonic flaw data for the computer and provide computer control of receiver gain and flaw-gate width. Also the design and fabrication of a multiple flaw gate system is described and evaluated.
