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.
Claims20
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.
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;
- 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.
A gas turbine engine system comprising:
- multiple debris capture devices operative to monitor lubrication oil of a gas turbine engine to detect a presence of debris in the oil;
- an oil debris monitor operative to monitor lubrication oil to determine a characteristic of the debris;
- and
- an oil analysis system operative to receive information corresponding to the presence of debris in the oil from the debris capture devices and information corresponding to the characteristic of the debris from the oil debris monitor;
- the oil analysis system being further operative to approximate a source of origin of the debris based on the information provided by the debris capture devices and correlate the characteristic with the source to determine whether the engine is operating within predetermined limits.
