Patent attributes
A method for monitoring thermal events in an aircraft engine compartment includes obtaining first sensor data from a first sensor located within an engine compartment of an aircraft. The method also includes determining a time series moving average based at least in part on a subset of the first sensor data. The time series moving average is indicative of an average temperature rate-of-change of the engine compartment. The method further includes determining a standard deviation of the time series moving average and detecting a trend of temperature rates-of-change that satisfy a rate-of-change criterion. The rate-of-change criterion is based on a multiple of the standard deviation, and the temperature rates-of-change are based on temperatures of the engine compartment. The method also includes generating an alert in response to detecting the trend. The alert is indicative of a thermal event associated with the engine compartment.
