Problems solved by technology
The scramjet engine needs the precursor to provide high-pressure and low Mach number gas. Since the traditional hypersonic vehicle design is a fully integrated coupling design of the precursor and the inlet, the mutual constraints are very serious, and it is difficult for engineering application and processing, and Parameter tuning is not easy

Embodiment Construction
[0032] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
[0033] A combined design method for an air-breathing hypersonic vehicle based on a cone-shaped flow field. The combined layout of a hypersonic vehicle adopts the combined design of a waverider precursor, a waverider wing, and an engine body.
[0034] refer to Figure 1 to Figure 8 , the design of the hypersonic cruise vehicle of the present invention adopts the design idea of different components and different reference waveriders, and realizes the componentized design of the overall layout of the hypersonic vehicle. This method breaks through the design constraints of traditional waveriders on aircraft size, shock angle, integration, etc., and can realize the flexible design requirements of variable parameters and variable working conditions in engineering applications.
[0035] The specific design process is as follows:
[0036] 1. Precursor design...

Description
technical field [0001] The invention belongs to the field of aircraft design, and in particular relates to a combined design method for an air-breathing hypersonic aircraft based on a conical flow field. Background technique [0002] Hypersonic vehicles usually refer to vehicles powered by scramjet engines or gliding at high speed. Compared with traditional rockets, they have the characteristics of lower cost, shorter service life, quick response, and strong maneuverability. An important index for the application of hypersonic vehicles is range and load capacity. The improvement of its design level is affected by many factors, such as scramjet engines, advanced aerodynamic layouts, lightweight and heat-resistant structures, flight control and other technical conditions, and each factor Under hypersonic conditions, it is characterized by close coupling with each other. In the design, not only single-disciplinary factors must be considered, but also the integrated design requi...
