Abstract: The method of characteristics is applied to design the inward turning axisymmetric basic flow field and the external compressing axisymmetric basic flow field. An integrated design method of inward turning inlet/Von Karman waverider for hypersonic vehicle with head-intake is proposed based on the shock intersection line and streamline tracing. The integrated configuration is also presented and an analysis of the integrated configuration is carried out, verifying the correctness and the feasibility of the method. The excellent characteristics of the inward turning inlet is basically retained for using the integrated design method and the integrated configuration is constructed by using the waverider with a high lift-drag ratio as the prototype. From the view of flow field coupling, the paper intends to reduce the complex wave interference between the body and the inlet, realizing the complete coupling of the internal and external flow of the aircraft.

Key words: hypersonic inward turning inlet, basic flow field, internal and external flow coupling, integrated design, streamline tracking
