[0046] The design principle of the present invention: according to several elements and assumptions in the close cone method, the corresponding relationship between the shock wave outlet line, the streamline tracing starting line and the waverider plane shape contour line is deduced, and the numerical value is given Solution. According to this relational expression, the plane shape contour design shape of the waverider can be set, that is, the plane shape can be customized, and the rationally designed waverider with a fixed plane shape, such as double-swept shape, S-leading edge waverider, etc., in low-speed performance , Longitudinal stability has performance advantages.
[0047] First, a brief introduction to the design principle of the close conical waverider is given, such as figure 1 As shown, ICC is the exit profile of the shock wave. Take a point on the ICC curve as the tangent line, and the plane perpendicular to this tangent line is called the close plane. According ...
