Aero-acoustic performance of a continuous transonic wind-tunnel axial-flow compressor

Xibei Gongye Daxue Xuebao, 2022
A three-stage axial-flow compressor was developed for a continuous transonic wind tunnel. The rotor-stator spacing and the ratio of number of rotor blades to number of stator vanes were properly chosen for the purpose of aero-acoustic noise suppression ...
