Abstract
This paper presents a unique set of unsteady pressure measurements during a surge and rotating stall event in a modern transonic high speed single stage axial flow fan rig. The unsteady pressure data were acquired using an array of 22 high frequency response Kulite transducers positioned over the rotor tip to show detail of the in-passage flow behaviour during stall and surge. In addition, Kulites were also positioned upstream, downstream and in the bypass duct of the rig to give a more general overview of the fan operation during the rotating stall and surge events.
