Abstract

In-service eddy current (EC) inspection of aircraft engine components is one of the most demanding NDE applications. Any defect in such high-performance components will have serious consequences, and hence reliable periodic inspections are required. Yet, it is known that significant improvements to the current implementation are desirable in various aspects. One of our recent modeling activities is directed toward developing a software simulator that is able to predict the performance of inspections and, hence, to examine any improvement ideas such as new probe designs on computers.
