| Abstract: | This paper studies the fluctuating lift of a cambered airfoil under sinusoidal gusts. The calculating equations of the fluctuating lift are then derived. The effects of cascade geometry parameters and aerodynamic parameters of rotor cascade and stator cascade in axial flow compressor to the rotor fluctuating lift and noise level are analyzed. |
