The embodiment of the invention provides a combined front-edge wave rider design method and a combined front-edge wave rider. According to the method, the appearance of the wave rider is divided into two parts, namely an engine body and a wing, and then the method of defining a front/rear edge curve is adopted, so that the design flexibility of the wave rider can be effectively improved, and the appearance more close to the actual can be acquired. The lower surface of the wing is intersected with a shock wave surface so as to form a wing front-edge line, and then the combined front-edge line of the wave rider is obtained; when the method is used for designing, not only can the features of the wave rider be guaranteed, but also the length-width ratio is flexible and the straightness of the tailing edge is guaranteed, the design method is more suitable for the actual aircraft. The lower surface of the engine body can be designed by using a positive filament line tracing method for giving the front-edge line, the lower surface of the wing can be designed by using an adverse filament line tracing method for riving the tailing-edge line. The main application range of the design method provided by the embodiment of the invention is configuration design for various hypersonic aerocrafts, and the design method is particularly suitable for designing future hypersonic aircrafts or gliding type aircrafts.
