Popis:	This paper presents the experimental results of rotordynamic forces on an open-type centrifugal impeller in whirling motion. For the whirling open-type impeller, the variation of the tip clearance produces the rotordynamic force. It was found that, [1] destabilizing force occures at small whirling/rotation ratio throughout all of the flow range, and [2] At smaller flow rate the magnitude of the force changes dramatically at a whirling/rotation ratio. The forces estimated from unsteady pressure distribution on the casing and that estimated from the pressure difference across the blades are compared with the measured rotordynamic forces.
