Our integrated health management "workbench" reduces the time, manpower and costs for diagnostic data analysis and recertification of reusable launch vehicle propulsion systems. Over the last five years, NASA and its contractors have developed advanced algorithms and methods targeted for improved launch vehicle propulsion system health management. Lacking in this research has been the substantial development of an integrated framework within which operations-oriented users may capture, access, manipulate and annotate features and events observed in the data or detected by these health management algorithms and tools. We solve several significant research problems enabling these advanced methods for operational support of NASA flight systems through the development of an innovative set of software tools which: 1) provide graphical knowledge capture and user interface tools allowing non-programmers to quickly define significant features and events in operations data; 2) provide for integration of advanced propulsion system diagnostic algorithms, such as software-based sensor data validation; 3) provide a full suite of integrated data analysis and visualization tools; and 4) provide automated generation of code modules for feature and event detection. Our competitive analysis and NASA's development experience confirm that these innovations provide a new and original capability for system health management.
Potential Commercial Applications: Our product strategy is centered around production and delivery of a user friendly software tool environment which enables engineers and scientists to rapidly construct and maintain system health management applications. It is our goal to complement this product with a comprehensive offering of engineering services ranging from user training to development and support of turnkey systems. Our targeted market niche is diagnostic and informed maintenance monitoring for aerospace, utility and chemical process industries.
