First Claim
Patent Images
1. 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, said fault isolation system predicting a current fault based upon said readings, and to a network communicating with a database of prior predictions, and the database associating the prior predictions with a confidence level for the current prediction; and
said fault isolation system providing the predicted current fault to an output, and the confidence level in the current prediction also being provided to the output.

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.

11. 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 predicting a current fault based upon said readings to a network communicating with a database of prior predictions, the database associating the prior predictions with a confidence level in the current prediction; and (c) said fault isolation system providing the predicted current fault to an output, and the confidence level in the current prediction also being provided to the output. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
