To achieve the compression capacity, compression efficiency, flow mass capture capacity, and geometric length of the hypersonic planar inlet controllable, a design method of the planar curved shock wave is proposed. The shock curve is specified with the B-Spline function in advance, and the domain of influence of the shock wave and the wall profile are solved by the rotational method of characteristics. With the inviscid CFD simulation of the concave shock wave, the present design method is validated. Three types of shock wave, including straight, concave and convex shock waves, are designed, and their performances are investigated. At on-design point, the variations of contraction ratio, total pressure recovery coefficient, pressure rise, and exit Mach number and flow angle with the governing angle of shock wave are illustrated. In addition, at off-design point, the variations of the total pressure recovery coefficient and flow mass coefficient with the angle of attack and Mach number are shown.
