The purpose of the present study, which is composed of two parts, is to predict analytically the steady performance of a supersonic through-flow fan in terms of design parameters. It is assumed that the fan cascade operates at supersnic axial velocity with a small angle of attack, camber and thickness. In 1st Report, the linearized lifting surface theory for a rotating annular cascade on the basis of the finite radial eigenfunction series approximation developed by the first author is extended to the supersonic through-flow fan model. Expressions of the disturbance flow field are derived, and the integral equation for the steady loading is numerically solved. The fundamental features of the blade surface pressure distribution dependent on the blade profile are demonstrated. The extensive parametric study of steady performance is presented in 2nd Report.
