The invention provides a gliding-cruising two-stage wave rider design method based on the osculating cone principle. The method includes the design of a gliding-stage wave rider and the design of a cruising-stage wave rider. Firstly, basic mold lines and design parameters are given, including a cruising-stage shock wave outlet mold line, a wave rider upper surface rear edge line, a cruising-stage Mach number Ma1, a shock wave angle beta1, a gliding-stage Mach number Ma2 and a shock wave angle beta2. The cruising-stage wave rider is designed first based on the osculating cone principle, and a wave rider front edge line is determined. Then, the lower surface of the gliding-stage wave rider is designed according to the front edge line so that the two stages of wave riders can share the same front edge line. The defects existing in designing hypersonic-speed gliding-cruising two-stage wave riders based on the cone derivation principle in the prior art are overcome; the two stages of wave riders can be designed according to task demands; the design method is more flexile; meanwhile, the two stages of designed wave riders have good wave riding performance at both the gliding stage and the cruising stage and have a high lift-drag ratio in the whole flying process.
