A helth monitoring expert system software architecture has been developed to support condition-based health monitoring of rocket engines. Its first application is in the diagnosis decisions relating to the health of the high pressure oxidizer turbompump of the Space Shuttle Main Engine. The post test diagnostic system runs offline, using as input the data recorded from hundreds of sensors, each running typically at rates of 25, 50, or 0.1 Hz. The system is invoked after a test has been completed, and produces suggestions, analysis, and an organized graphical presentation of the data with important effects higlighted. The overall expert system architecture has been developed and documented so that expert modules analyzing other line replaceable units may easily be added. The architecture emphasizes modularity, reusability, and open system interfaces so that it may be used to the analyze other engines as well. In its first application, the expert system has identified drifting sensors, anomalous shaft motion and preburner pump bistability.
