航空发动机性能趋势监控定量化的方法研究

通过对某型飞机飞行参数记录系统记录信息的破译、分析和处理,对得到的与发动机性能相关的数据在航空发动机性能趋势监控中的应用进行了较为深入的研究。提出了如何利用这些数据得到综合参数,并采用综合参数作为评判发动机性能状况的量化指标以及在此基础上建立发动机预警信号系统的实现方法。最后,利用实际的发动机数据进行了验证。 

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.
