Abstract
Systems and methods for monitoring gas turbine engines are provided. In this regard, a representative method includes: monitoring lubrication oil at multiple locations of the gas turbine engine to detect a presence of debris in the oil; determining a characteristic of the debris in the oil; and correlating the characteristic of the debris with the location of detection to determine, while the gas turbine engine is operating, whether the engine is operating within predetermined limits.
Claims11
A method for monitoring a gas turbine engine comprising:
- monitoring lubrication oil, at multiple locations of the gas turbine engine, to detect a presence of debris in the oil;
- approximating a source of origin of the debris;
- determining a characteristic of the debris;
- and
- correlating the characteristic with the source to determine whether the engine is operating within predetermined limits;
- the monitoring, approximating, determining and correlating being performed while the gas turbine engine is operating.
