In multistage axial compressors used for gas turbine engines, it is import ant to clarify unsteady phenomena such as surge and rotating stall. The purpose of this study is to develope a practical analysis method for both the surge and rotating stall in axial compressors. In this paper, firstly, some characteristics of the unsteady phenomena in axial compressors are summarized, derived from the measurments in test compressors. Secondary, a numerical method for the unsteady phenomena assuming incompressible flow is described. A feature of the method is solving the equations by Galerkin's method with the circumferential flow distortion expressed in the form of a high-order Fourier series. Finally, the usefulness of the method is examined by some results from a parameter-survey computation and by a comparison with the measured results in a 3-stage test compressor.
