Abstract

High frequency spectra of three single-stage, high-speed compressor rotors were analyzed for behavior indicative of rotating stall. The compressor rotors were straight, backward swept, and forward swept. Power integrated over time showed promise as a prestall warning pararmeter. For the straight and swept back rotors, stall warning times varied from several seconds to 0.5 seconds. The forward swept rotor however, was difficult to characterize since surge played an important role in the stalling characteristic and stall appeared to originate at the hub of the rotor, away from pressure transducers located on the casing.
