On-line risk assessment model for aero engine using LS-SVM

Abstract

The Least Square Support Vector Machine (LS-SVM) is applied in aero engine risk assessment with gas path fault diagnosis. Firstly, the deviations of engine cruise data from flight data recorder are analyzed, and sample data for modeling is obtained. The architecture of fault diagnosis model is established. Secondly, model selection is achieved using Pattern… (More)
