Abstract
A system and method are provided for monitoring engine thrust bearing temperature deviations. Initially, key engine parameters are measured. A bearing temperature rise can be predicted based on the measured parameters. The predicted rise value is compared with the actual rise value to generate a comparison value. The system is trained to respond to the comparison value to prevent catastrophic failure.
Claims14
A method for predicting sump temperature rise in a gas turbine engine, comprising the steps of:
- measuring predetermined engine parameters;
- multiplying each predetermined engine parameter by a related coefficient to obtain a corrected parameter;
- measuring actual sump temperature rise;
- and
- using the corrected parameters to predict the sump temperature rise.
