Abstract: A method and system for detecting degradation of a lube oil temperature control valve in a gas turbine engine. The system includes temperature sensors measuring lube oil tank temperature, heat exchanger outlet temperature, and header temperature downstream of the temperature control valve. Valve position is determined based on temperature measurements and extracted contextual features describing operating conditions. The system determines valve degradation by comparing valve positions to expected positions, analyzing seasonal variations, and detecting deviations from baseline operation. The system predicts potential valve failures before peak ambient temperature periods based on detected degradation rates and historical patterns. Preventative maintenance notifications are generated with recommended timing based on the predicted valve failure timeline.

Abstract: The unexpected failure of a turbomachine can be costly and dangerous. Processes may collect data from a turbomachine, calculate durations of machine events from the collected data, and apply a model to those machine-event durations to predict future machine-event durations and/or detect trends in the machine-event durations. This predictive output may be utilized to inform downstream functions regarding the health of the turbomachine. For example, a downstream function may utilize the predictive output to detect degradation or a potential future failure in the turbomachine and trigger remedial functions, such as alerts and/or controls, to prevent or mitigate the degradation or failure of the turbomachine.
