Abstract
A system and method for predicting a remaining oil life of oil in a gearbox of an air turbine starter of a vehicle. The method includes generating a temperature data, generating an environmental data set by an environmental sensor, predicting a remaining oil life based on the temperature data set and the environmental data set and scheduling a maintenance event in response to the prediction of the remaining oil life.

A method for predicting a remaining oil life of oil in a gearbox of an air turbine starter of a vehicle, the method comprising:
- generating a temperature data set by sensing a temperature from at least one temperature sensor external of the gearbox;
- generating an environmental data set by an environmental sensor, the environmental sensor adapted to sense an environmental condition relative to the air turbine starter;
- predicting, by a controller module, a remaining oil life based on the temperature data set and the environmental data set;
- and
- scheduling a maintenance event in response to the prediction of the remaining oil life.
A system for determining an oil quality for oil of an air turbine starter, comprising:
- at least one temperature sensor adapted to sense a temperature external of a gearbox;
- and
- a controller module configured to estimate a model of oil quality based on the sensed temperature, and to schedule a maintenance event in response to the estimated model of oil quality.
A method for predicting a remaining oil life in a gearbox of an air turbine starter, the method comprising:
- generating an oil temperature data set by sensing a temperature, from a temperature sensor external of the gearbox, that is indicative of a temperature of the oil within the gearbox;
- generating an environmental data set comprising at least one of average ambient air temperatures during takeoff or average cruising altitudes;
- generating an operational data set comprising at least one of total number of starting cycles for the starter, rpm during starting, or duration of air starter operation;
- predicting a remaining oil life by inputting the oil temperature, environmental, and operational data sets, along with an oil type, into a controller module;
- and
- operating a starting cycle of the air turbine starter based on the predicted remaining oil life.
