• In order to grasp the unsteady aerodynamic force acting on blades due to a rotating stall, properties such as velocity, pressure fluctuations and vibrations of blades are measured and relations between them are studies by using a single stage compressor. Consequently, the following conclusions were obtained. (1) It is clear that the velocity (rotating speed) and the width of stall cell are significant factors governing the aerodynamic force. (2) It is reasonable to regard the square wave of the velocity fluctuation as the aerodynamic force acting on a blade.
