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, wherein predicting the remaining oil life is not based on direct sensing within an interior of the gearbox;
- 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, wherein the at least one temperature sensor is located in a primary air flow path and couples to a housing of the air turbine starter;
- 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.
