Abstract

UK MOD is sponsoring work over a wide range of NDE Technologies for Aero Gas Turbine inspection. Much of this work has been aimed at Ultrasonics, where research has concentrated on improving the reliability and sensitivity of detection. Two examples are described, where fundamental research has been translated into equipment capable of real-time operation: In the first example signal processing and state of the art electronics have been combined to greatly improve the signal to noise ratio in conventional ultrasonics. In the second example a novel use has been made of mode conversion and surface acoustic waves to reliably detect and characterize surface and near surface flaws.
