Abstract
A method and system is developed that provides a confidence measure of a prediction of a fault in a gas turbine engine. The confidence measure is developed based upon evaluating the results of a plurality of past predictions and comparing them to an actual fault.
Claims10
A fault diagnosis system comprising:
- a fault detection system for taking in a plurality of sensor readings from a gas turbine engine;
- said plurality of sensors providing readings to a fault isolation system, and to a network communicating with a database of prior predictions, and the database associating the prior predictions with a confidence level;
- and
- said fault isolation system providing a predicted fault to an output, and a confidence level in the predicted output also being provided to the output.

A method of operating a fault prediction system including the steps of:
- (a) taking in a plurality of sensor readings from a gas turbine engine;
- (b) providing readings to a fault isolation system, and to a network communicating with a database of prior predictions, the database associating the prior predictions with a confidence level;
- and
- (c) said fault isolation system providing a predicted fault to an output, and a confidence level in the predicted fault also being provided to the output.
