Contract: N68335-07-C-0098
Award Amount: $749,793.00


Impact Technologies, in collaboration with Goodrich and Pratt & Whitney proposes to further mature and demonstrate the Prognostics Health Monitoring (PHM) technologies developed in Phase I for on-board PHM of the shaft-coupling designed for the Joint Strike Fighter (JSF). In addition, Impact and its collaborators also propose to facilitate integration of this technology with the PHM prototype for the JSF drive train system. The shaft-coupling PHM capability will employ installed accelerometers and other PHM and control sensors on the JSF engine and drive train, to predict health index of the shaft-coupling, along with predicted time-to-failure and confidence of prediction. The Phase I effort demonstrated the feasibility of the shaft-coupling PHM software using an in-house designed Shaft-Coupling Test Stand. During Phase I, Impact used the test stand data to develop and evaluate candidate PHM algorithms that are based on signal processing, structural analysis and information fusion techniques. During Phase II, Impact proposes to further test and develop the PHM algorithms on full-scale rig at the Penn State-Applied Research Lab's Mechanical Diagnostic Test Bed and on a JSF coupling test stand at Goodrich-Rome. Impact will also test and integrate the developed algorithms on JSF test cells through collaboration with primary JSF OEM manufacturers: Rolls Royce and Pratt and Whitney. The overall Phase II project goal is to develop embedded, real-time PHM algorithms and enable Phase III transition to fixed and rotary wing applications, such as the JSF and V-22 Osprey.
