AbstractImpact Technologies, in cooperation with Pratt & Whitney and Qualtech Systems Inc., propose to develop and commercialize a simulation-based design application for dynamic failure mode and effects analysis (FMECA++) that specifically focuses on designing and verifying EHM technologies for legacy and new acquisition engines. The proposed FMECA++ design software will be capable of; 1.) Automated failure mode insertion and propagation analysis, 2.) EHM algorithm design and verification, 3.) Full dynamic engine simulations, 4.) Embedded code generation for the ICF and 5.) Direct interfacing with the QSI TEAMS Product. In order to address this multi-scale modeling functionality, the Impact team will leverage the COTS software suite by Mathworks called Simulink/Stateflow and use XML data schema for integration with the QSI software. Utilizing the Simulink software as the core analysis engine, the design software will be capable of providing full functionality from the specific EHM algorithm level to the higher-level engine health management reasoners. The Impact team believes this innovative approach to EHM design/analysis will truly represent the next generation in capability needed for the VAATE Intelligent Engine focus area and can be directly incorporated into the AFRL’s ICF facility. In addition, the JSF Program Office (JPO) has recently supported a program at Impact focused on vehicle-level modeling and will be leveraged during this Phase II program, thus reducing our Phase II proposed cost by over $150K. The end goal is to create a comprehensive simulation-based design tool to support dynamic fault propagation analysis; EHM cost/benefit analysis, as well as EHM testing and validation that enables EHM design and trade studies much earlier in the overall design process where significant cost savings can be realized. A realistic application of the software will be based on comprehensive EHM analysis for the Pratt & Whitney F119 and F135 engines.
