Abstract
A method of predicting an auxiliary power unit fault in an aircraft having an auxiliary power unit and multiple sensors related to the auxiliary power unit, components thereof, and systems related thereto, including receiving a sensor signal from at least one of the multiple sensors to define a sensor output, comparing the sensor output to a reference value and predicting a fault in the auxiliary power unit based on the comparison.
Claims20
A method of predicting an auxiliary power unit fault in an aircraft having an auxiliary power unit and multiple sensors related to the auxiliary power unit, components thereof, and systems related thereto, the method comprising:
- receiving, during at least one of pre-flight or post-flight, a sensor signal from at least one of the multiple sensors to define a sensor output;
- comparing, by a controller, the sensor output to a reference value for the sensor output;
- predicting, by a controller, a fault associated with the auxiliary power unit based on the comparison and prior to an occurrence of the predicted fault;
- and
- providing, by a controller, an indication of the predicted fault.
A system comprising:
- one or more devices configured to:
- receive, during at least one of pre-flight or post-flight, a sensor signal from at least one of a set of sensors, associated with an auxiliary power unit of an aircraft, to define a sensor output;
- compare the sensor output to a reference value for the sensor output;
- predict a fault associated with the auxiliary power unit based on the comparison and prior to an occurrence of the predicted fault;
- and
- provide an indication of the predicted fault.
A non-transitory computer-readable medium storing instructions, the instructions comprising:
- one or more which, when executed by a processor of a device, cause the processor to:
- receive, during at least one of pre-flight or post-flight, a sensor signal from at least one of multiple sensors, associated with an auxiliary power unit of an aircraft, to define a sensor output;
- compare the sensor output to a reference value for the sensor output;
- predict a fault associated with the auxiliary power unit based on the comparison and prior to an occurrence of the predicted fault;
- and
- provide an indication of the predicted fault.
