Ultrasonic Techniques for hidden corrosion detection
Introduction
Corrosion is one of the serious problem affecting airforce and other aviation industries. It affects the aircraft on its wings, surface, between joints and fasteners. The presences of corrosion underneath the paints of surface and between joints are not easy to be detected. The unnoticed presence of corrosion may cause the aircraft to crash leading to human and money loses. To detect the corrosion present on the metal surface, various method ....etc

Abstract
Morphing aircraft are multi-role aircraft that change their external shape substantially to adapt to a changing
mission environment during flight.2 This creates superior system capabilities not possible without morphing shape
changes. The objective of morphing activities is to develop hig ....etc

Detection of corrosion damage in aircraft wing skin structures is an ongoing NDT challenge. Ultrasonic methods are known and well-accepted techniques, which are relatively simple to carry out in terms of setup, probes and instrumentation and operator training. However, with conventional inspection from the top surface using a transducer at normal incidence (0o to the normal to the surface) producing a visual picture in the form of a C-scan, it is very tie consuming to point-by-p ....etc
