To achieve better matching between the shape of the capture section and inlet entrance line and the forebody shock wave, an integration design method is proposed based on the shape of the forebody shock wave for the integration design of waverider forebody/inward-turning inlet with the intake of abdomen. First, the flow field of the waverider forebody is calculated, and the forebody shock surface is extracted. Second, the Inlet Full Capture Curve (IFCC) is acquired by projecting the Inlet Capture Curve (ICC) on the forebody shock surface. Third, the shape of the incident shock in the basic flow field is determined after the axis of center body is given. Then, the basic flow field is determined by the method of characteristic after the distribution law of the Mach number along the compression boundary is presented. Finally, the inlet lip is obtained through the projection of ICC on the incident shock surface of the inlet in the direction of the incoming flow, and the final inlet surface is obtained through streamline-tracing and viscosity correction. Numerical results show that the inlet mass capture coefficient reaches 0.976 at Mach number 7.0 for a typical waverider forebody, and the Mach number, pressure ratio and total pressure recovery coefficient at the isolator exit are 3.17, 38.9, and 0.487, respectively.
