An Analysis of Noise Characteristics of a Turbojet Engine

Jin YeZhuang Sheng Yuansheng  
A large amount of useful information for qualitative and quantitative analyses of the sound source characteristics has been obtained by measuring sound pressure level of the turbo-jet-engine noise during its static testing, The engine rotational frequency and its harmonics have been detected by using Zoom spectrum analysis technique, It is there fore predicted that there,Perhaps,exists some problems of rotor misalignment. By combining power spectrum analysis with the results of caculation,it is shown that the compressor rotation noise is of high and discrete frequency
