We describe the development and application of a knowledge-based expert system for the space shuttle main propulsion propellant loading. This tool, the propulsion advisory tool (PAT), performs system diagnostics and engineering assessments for space shuttle main propulsion system engineers. The PAT identifies both actual and potential system failures and provides pertinent data for anomaly resolution. Over 150 measurements are monitored in real time at the full sample rate in order to evaluate system performance. Rules for the system are coded in plain English and are based on existing requirements documents and knowledge captured from propellant loading experts. In this way, the expert system works within a framework similar to the way humans would; a system based on human logic and reasoning. The PAT knowledge base interfaces with a user display on the same platform for advanced system schematics, data representation, and data management. The Rockwell International knowledge base diagnostic system and the Lockheed Space Operations Company user display are planned to run on an integrated workstation.
