The invention discloses a wide-domain time-varying waverider shape design method based on a bending shock wave theory, and relates to near space hypersonic flight vehicle design. And determining a flight Mach number range according to the flight envelope, and determining a design Mach number and a flight height of each level of waverider shape of the wide-domain time-varying waverider shape. A three-dimensional leading edge molded line and a waverider area of a fixed wide-domain time-varying waverider shape are given according to flight mission requirements. A shock wave molded line equation of the basic flow field is adjusted, and according to the geometrical relationship between the design curves, all levels of waverider shapes with the same three-dimensional front edge molded line and waverider area are obtained through rapid solving by means of the bending shock wave theory. According to the plot ratio requirement, the upper surface of the wave rider is constructed into a plane or a convex surface. And combining all levels of waverider shapes to realize wide-range time-varying waverider shape design based on the bending shock wave theory. The waverider appearance can be changed autonomously and continuously according to task requirements and the flight environment, the aerodynamic performance under the flight envelope is effectively improved, and the waverider can adapt to wide-speed-range flight working conditions and various flight tasks.
