Measurement and Analysis of the Unsteady Normal Force and Pitching Moment on an Axial Flow Fan Rotor Blade Element.
Abstract
In recent years, the radiated noise problem has emerged as one of the most serious problems associated with the design of axial flow turbomachines. Prediction of the noise radiated from a turbomachine is dependent upon a knowledge of the fluctuating forces on the blades. The ARL axial flow research fan (AFRF) was designed specifically to provide a capability for detailed research which will define the response of axial flow turbomachinery blade elements and/or blade rows to subsonic incompressible unsteady flow of the type encountered in practice. The purpose of the memo is to describe this facility and the specialized equipment that has been developed for use in it, and to present some preliminary unsteady force data.
