A modified small perturbation stability.prediction model for axial compressors with circumferential inlet distortions is established and applied to investigate the effect of fore/aft-loaded rotor on compressor stability.under circumferentially.distorted inlet *** inlet total pressure distribution downstream of the distortion screen is measured in experiments and employ.d for simulations which are implemented via time-space spectral *** stall inception prediction results via the stability.model indicate that the compressor with aft-loaded rotor not only.performs better in terms of stability.under uniform inlet,but also maintains a larger stability.margin under circumferentially.distorted *** experiments for compressors with fore-loaded and aft-loaded rotor are respectively.carried *** results validate the reliability.of numerical simulations and the predicted conclusion that the aft-loaded rotor is beneficial for compressor ***,the ability.of the developed theoretical model for compressor stability.prediction under circumferential distortions is *** addition,dy.amic pressure signals at rotor tip measured in experiments illustrate that the circumferential distortion has little effect on the compressor stall pattern.
