The primary NASA application for the acoustic emission sensing system will be in structural health monitoring and leak detection. The system is well-suited for predicting end of useful life conditions for composite structural components, especially those in stable operational load regimes. The traditional acoustic emission component of the system will aid in detection and localization of impact events.
The Department of Defense (DoD) has made considerable investment in implementing condition based maintenance (CBM) throughout its fleet. Emphasis is placed on aerospace applications which prove expensive to survey but require long lifetimes to avoid costly replacement. Nondestructive verification systems for monitoring of critical infrastructure has also seen increases. With aging bridges and railways, an improved system for component lifetime and failure prediction is necessary.
