Analysis of turbojet and turbofan jet noise in aero engine test

Huang Jingjing Wu Zhizhen Lei Yong (Northwestern Polytechnical University, Xi'an, 710072)  
The noise will pollute the environment seriously when the aero engines are tested. Through noise data collection and power spectrum analysis of turbojet and turbofan, the main noise source and characteristics of noise are discussed. The experiment result indicates that the theoretical analysis is in conforming to experimental analysis. The experiment also provides experience for noise based fault diagnosis.
