Method for Quantification of Aeroengine Performance Tendency Monitoring

The application of data acquired from a certain engine to the performance tendency monitoring of aeroengine is studied in depth.The approach to obtaining integrative parameter from these data is demonstrated.The integrative parameter,in turn,can be employed as a quantitative criterion for judging the engine performances on which basis engine early warning signal system can thus be established.Finally,the method was verified by real engine data.
