Prognostics and Health Management (PHM) for Digital Electronics Using Existing Parameters and Measurands Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-093 Topic Title: Prognostics and Health Management (PHM) for Digital Electronics Using Existing Parameters and Measurands Proposal No.: N052-093-0228 Firm: Impact Technologies, LLC 200 Canal View Blvd, Ste 300 Rochester, New York 14623-2851 Contact: Michael Roemer Phone: (585) 424-1990 Web Site: www.impact-tek.com Abstract: In response to SBIR topic N05-093, Impact Technologies proposes to develop and demonstrate an onboard integrated prognostics and health management (PHM) system for aircraft digital electronic boards. The proposed non-invasive PHM system, consisting primarily of advanced software and a minimal sensor array, will be capable of detecting incipient faults, predicting the remaining useful life of critical components, and recommending corrective maintenance actions. This system will integrate collaborative diagnostic and prognostic techniques from engineering disciplines including statistical reliability modeling, damage accumulation models, physics of failure modeling, signal processing and feature extraction, and automated reasoning algorithms. In this approach, cradle-to-grave health state awareness is achieved through the use of model-based assessments in the absence of fault indications, and by updating these model-based assessments with sensed information when it becomes available. Based on this solid foundation of health state information, complementary prognostic techniques including analysis of projected operating conditions by physics-based component damage accumulation/aging models, empirical (trending) models, and system-level failure progression models will be used to develop verifiable prognostic algorithms. The proposed approach, diagnostic techniques, and prognostic models will be demonstrated through seeded fault testing on a relevant commercially available digital electronic board. Only through the utilization of all of these sources of engineering information can the Navy fully realize the PHM concept for digital electronic boards on the JSF. Benefits: The development and integration of embedded diagnostics and prognostics for aircraft digital electronic boards will provide multiple benefits including: improved safety associated with system operations, reduced life cycle or total ownership costs, and increased combat readiness/availability of military systems. Furthermore, the work will contain many generic elements that are readily applicable to a wide range of related applications. The integrated diagnostics & prognostics approaches, techniques, and specific algorithms could also be implemented in a wide range of ground-based and naval military applications, as well as in civilian commercial aviation applications (passenger aircraft, cargo transports, business jets, private aircraft, etc.).
