| Abstract: | Sources of compressor noise are usually considered as multiple pure tone noise,interaction noise and broadband noise.In the paper,the noise propagation equation of steady force on the compressor rotor blade is derived.The numerical results are compared with the WP 11 compressor rotor acoustical experiment.The theoretical and experimental investigations indicate that the steady force noise on the compressor rotor blalde is an important source of the compressor noise. |
