CALCE's Prognostics and Health Management Group has been awarded a threeyear NASA project, �Reliable Diagnostics and Prognostics for Critical Avionics Systems.� CALCE is developing and validating system- and component-level diagnostic and prognostic methods to increase the safety of avionic systems. This research aims to improve the accuracy of avionics fault detection capability, boost in-flight performance, reduce maintenance costs, and improve overall aircraft reliability.
Additionally, this project involves developing algorithms for offline data analysis to detect soft faults and find patterns of soft faults in relation to other relevant system events. Prognostic algorithms are also being developed to track degradation and predict the remaining useful life for avionics systems. The project will include investigation of several potential mathematical techniques and/or a combination of these techniques to design diagnostic and prognostic algorithms.
