A generalized, steady-state, radial inlet pressure distortion index Kr was derived theoretically, and evaluated by full-scale tests on a J52-P-8A turbojet engine. Test data at stall for one-per-span hub-radial and tip-radial distortion generalized with the derived distortion index Kr as a function of low compressor rotor speed and corrected average radius ratio. At each corrected rotor speed, the Kr defines the distortion tolerance of the compressor, regardless of the radial position, or extent, of the distortion. Author
