航空发动机性能监视参数选择的研究

INVESTIGATIONS ON SELECTING PERFORMANCE MONITORING PARAMETERS OF AEROENGINE

介绍了发动机性能监视参数选择的必要性，以ＪＴ９Ｄ－７Ｒ４Ｅ发动机为例，利用敏感性、相关性和Ｊ值分析技术对性能监视参数选择方案进行了研究，得到了３种参数组合下的２３个可行性方案。本研究方法及结果具有一定通用性，对发动机性能监视参数的选择具有重要指导意义。

The necessity of selecting performance monitoring parameters of aeroengine is described here.Taking JT9D 7R4E engine for an example,investigations on multiple selected groups of performance monitoring parameters have been executed by utlizing analytical techniques of sensitivity,correlation and J criterion,and then 23 feasible groups based on 3 kinds of compound parameters are drawn.Generally speaking,the research methods and results presented here are common and significant on selection of parameters applied to engine monitoring
