Abstract The velocity change and tangential force acted on the rotor of an axial flow compressor were analyzed in consideration of the rotating stall condition and the characteristics of tangential force. The principle and process of rotating stall were expounded theoretically. Then the tangential force acted on the rotor of axial flow compressor was deduced,when the compressor works in both normal and stall conditions. The characteristics of tangential force in rotating stall condition were obtained,and a comparison between the simulated and theoretical results was carried out. The feasibility of the theoretical analysis was verified by experimental simulations and the characteristics of tangential force and velocity change in rotating stall condition were obtained. The work mentioned above provides a useful reference to the subsequent vibration analysis and optimum structure design of compressor rotors.
