The invention discloses a wave rider rapid analysis design method based on a bending shock wave theory, and relates to near space hypersonic flight vehicle design. Two of a wave rider outlet capture molded line, a wave rider horizontal projection molded line and a shock wave outlet molded line are randomly specified according to design requirements, a geometrical relationship between design curves is established, and an analytical expression of a wave rider three-dimensional front edge molded line and a multiplied three-dimensional shock wave is solved. Taylor series expression of streamlines in an osculating plane is rapidly obtained by using a flow field analysis method based on a bending shock wave theory, and waverider parameterization expression considering incoming flow conditions and shock wave shapes is realized through coordinate transformation. According to the plot ratio requirement, the upper surface of the wave rider is constructed to be a plane or a convex surface, and rapid analysis design of the wave rider based on the bending shock wave theory is achieved. The design efficiency is effectively improved while the design precision of the wave rider is guaranteed, a higher lift-drag ratio and better wide-area performance can be obtained by selecting a proper design curve, and rapid optimization design of the wave rider in engineering is facilitated.
