Description

The detection of crack growth in aircraft structures through the use of acoustic emission techniques has been demonstrated to be feasible in recent years. Numerous problems still remain to be overcome, but a new DARPA program will address the most critical areas and build a flyable acoustic emission monitor demonstrating the new technology. A history of the field and a program overview are given.
