| 摘 要： | 在对发动机性能参数相关性研究基础上,结合多元线性回归预测模型,提出了一种能够考虑发动机众多因素对因变量影响的发动机性能预测模型.使用该模型对发动机排气温度(EGT)进行预测时,能够兼顾到p4.95,N2,T3,N1,pB等性能参数对EGT影响.最后使用一组某民用机型发动机飞行试验数据对模型进行了验证,并与加权一阶局域法进行了对比.结果表明,该模型预测精度优于加权一阶局域法,该方法可以为这种机型发动机故障预测提供决策依据.

| Abstract: | Based on the research of aeroengine performance parameters relativity,an aeroengine performance parameters forecasting method was proposed using multiple linear regression model,in which the effect of multiple factors on dependent was considered.Some aeroengine performance parameters,such as p4.95,N2,T3,N1,pB,were analyzed before forecasting of EGT series.At last,the proposed model was verified through some types of aircraft aeroengine performance parameters data obtained from flight experiment,and then com... |
