小波分析在航空发动机性能趋势监控中的应用

An Application of Wavelet Analysis in Aeroengine Performance Tendency Monitoring

简要分析了小波变换的原理、应用和算法。利用MATLAB编程 ,初步探讨了小波分析在发动机性能监控方面的应用。最后 ,通过实际的发动机数据对这种方法进行了验证 。

The principle, application and arithmetic of wavelet transform is analyzed briefly in this paper. Also discussed is the application of wavelet analysis of aeroengine performance tendency monitoring. Finally, the method is demonstrated with actual engine data. The result and application prospect are discussed.
