Embodiment Construction

[0018] Aspects of the present disclosure are directed to a system and method for predicting oil life of oil in a gearbox of an air turbine engine starter. As used herein, the term "oil life" is one or more values ​​indicative of the quality of oil life. By way of non-limiting example, oil life can be considered as a numerical value, a comparison between values ​​(such as greater than, less than, a true-false indication, etc.), a range of values, or as an oil quality model that can indicate that the oil no longer has the required point of performance. That is, oil life represents the span between when the oil is new and when the oil performance has reached a minimum threshold of actual or expected performance. Oil life can be given in terms of cycles, miles, operating hours, weeks or percentage. Thus, the term "remaining oil life" refers to the number of cycles, miles, operating hours, weeks or percentage of oil life that can occur before the oil reaches a minimum performance...

Abstract

The invention provides a system and a 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.

Description

technical field [0001] The present disclosure generally relates to a system and method for predicting oil life in a gearbox of an air turbine starter. Background technique [0002] Owners of machines or vehicles powered by air turbine engines may incur costs due to periods of unavailability or downtime. Downtime is sometimes associated with downtime of air turbine engine components. Air turbine engine assemblies include air turbine engines and engine accessories such as starters or generators. To reduce the likelihood or frequency of downtime, a preventive maintenance program has been implemented. [0003] Periodically perform preventive maintenance on engine accessories based on wear rate or usage. Engine accessories experience or are subjected to various loads, weather and other factors which inevitably mean that engine accessories or parts of engine accessories will wear at a different rate than other components. Worn components can result in inefficient operation or ...
