Equation 2.12 may be expressed for the full AIP or a tip or hub region at the AIP in the form: (2.32) Δ PRS = Δ PRS C + b Δ PRS R Introducing circumferential and radial distortion parameters, DPC and DPR, for pure patterns (2.33) Δ PRS C = K C ( DPC ) (2.34) Δ PRS R = K R ( DPR ) The terms KC and KR are empirically established circumferential and radial compressor sensitivities and are independent of the pattern. Then, for a combined distortion pattern (2.35) Δ PRS = K C ( DPC ) + bK R ( DPR )which may be written (2.36) Δ PRS = K C [ ( DPC ) + B ( DPR ) ]where B = bK R K C The term B is a specified function of corrected flow and is independent of the pattern. Equation 2.36 may be used to define a screening parameter: (2.37) DPS = ( DPC ) + B ( DPR ) For pure circumferential distortion DPR = 0 For pure radial distortion DPC = 0, b = 1.0
