| Abstract: | 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 |
