摘要
出于航空发动机性能预测参数融合的需要,需要对原始参数的非线性相关性的大小进行判定。本文利用基于分形理论的性能参数非线性相关性分析方法,对所选参数之间的非线性相关性进行分析,找出相关性最强的组合,本文研究过程与结果为性能预测提供了结果支持与非线性相关性分析的方法参考。
For the parameter fusion of aero engine performance prediction,it is necessary to determine the magnitude of the nonlinear correlation of the original parameters.This paper uses the method of nonlinear correlation analysis of performance parameters based on fractal theory to analyze the nonlinear correlation between the selected parameters,and have found the airway combination with strongest correlation.The research process and results provide results support for performance prediction and reference for nonlinear correlation analysis.
