Abstract
A method is 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.
