Prediction of the Total Sound Level of the Annular Combustor Noise of Aircraft Engine Based on SVR

Because of the high temperature and high pressure environment inside the annular combustor of an aircraft engine, the direct measurement of the burner noise is very difficult. This paper set up the model of the total sound level and the effect factor SVR though analyzing the relationship between the total sound level and noise parameters of the combustion chamber the annular combustor an aircraft engine and the influence factors,, and it is better than multiple regression mode and the projection pursuit regression model, and predict the predicting samples so it is important for aero-engine design and reliability analysis.
