Ensuring the Integrity and Veracity of an Interactive Fault Diagnosis and Isolation System for a Gas Turbine Engine.

摘要

The tasks involved in developing a fault diagnosis expert system for a gas turbine engine are examined. Particular attention is given to the options available to maximise the quality of the advice given by the expert system. All phases of system development from knowledge acquisition, through to system support are covered. A general example of diagnosis by engineering analysis is given to demonstrate the concepts involved. Using acquired knowledge, a limited qualitative fault model of the TF30-P3 gas turbine engine afterburner has been developed, and application to some fault case examples is described. Australia. (JS)
