 Previous work at Caltech has developed an air
injection controller for rotating stall based on the idea of a
shifting compressor characteristic.  To further understand the
properties of this controllers, a series of open loop tests were
performed to measure the performance characteristics of an axial flow
compression system when air was injected upstream of the rotor face.
The distance from the rotor face, the span-wise position, and the
angle relative to the mean axial flow were varied.  These tests show
that the injection of air has drastic effects on the stalling mass
flow rate and on the size of the hysteresis loop associated with
rotating stall.  The stalling mass flow rate was decreased by 10\% and
the hysteresis loop was completely eliminated under some conditions.
