Rotating stall is an interesting phenomenon that occurs in both axial and radial rotors. It is still poorly recognized in radial rotors. That was the reason to carry out investigations of pressure oscillation in streams, loudness and flow to find a possibility of the hysteresis elimination by the entry whirl consistent with peripheral velocity direction. Experiments have confirmed the cancellation of the hysteresis in the condition of forwarded whirl with the vane angle + 30°. In the paper are described results of tests.
