Dynamic Decision Support (D2S) for Real-Time Assessment of System Health and Fault Contingency Planning Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-104 Topic Title: Dynamic Decision Support (D2S) for Real-Time Assessment of System Health and Fault Contingency Planning Proposal No.: N052-104-0419 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: Impact Technologies, in collaboration with Honeywell Engines and Systems, propose to develop an innovative Dynamic Decision Support (D2S) concept for critical aircraft systems using simulation-based fault classifiers and adaptive contingency management techniques, which will be implemented through a real-time software agent architecture. The significant technology advancement proposed herein is based on using dynamic model simulations in a real-time computing environment to not only diagnose faults, but also to determine "on the fly" how accommodate for them. Current on-board technologies have to map fault conditions to an associated set of pre-determined contingency plans, which can not possibly account for the entire set of fault scenarios that can occur in flight. Hence, the innovations of this project include: 1) Development and demonstration of an agent-based software architecture that is capable of executing simulation models of critical aircraft systems with an adaptive flight control component that performs fault contingency management in real-time; 2) Develop simulation-based fault classification algorithms for the Honeywell Power Thermal Management System (PTMS) with real-time functionality in all system operating modes; 3) Develop contingency management algorithms using dynamic performance assessment calculations and flight control command generation under faulty aircraft system dynamics constraints; and 4) Develop a Simulink-based demonstration of the dynamic contingency management and fault-adaptive control system with application to the Honeywell PTMS. Benefits: The successful completion of the proposed work will substantially improve the performance, reliability, and survivability in both military and commercial aircraft systems without introducing significant hardware modifications. The potential military and commercial use of the developed technologies is broad, with specific application to the F-35 aircraft as the recipient of the PTMS. However, as an adaptable approach to advanced health management, examples of key customers that could benefit through use of the developed technologies include: unmanned combat air vehicles, future combat systems, commercial airlines, land and marine propulsion systems, industrial actuation systems, and robotic applications. The aircraft domain alone has thousands of potential systems to address with this technology. Return
