The invention discloses a waverider front body/three-channel air inlet channel integrated design method based on a flow direction double waverider principle, and belongs to the field of hypersonic flight vehicle inner and outer flow integrated design. The method is essentially characterized in that the relation between a waverider precursor external flow field and an inward turning air inlet channel internal flow field is established, an internal and external flow integrated axial symmetry reference flow field model is designed and researched, an osculating flow field is adopted in the reference flow field, and a molded surface is designed through streamline tracking, so that a novel waverider precursor/air inlet channel integrated design theory is developed. The front edge of the waverider front body and the front edges of the three inward turning air inlet lip openings can be attached to a shock wave face, the waverider front body serves as a pre-compression face of the air inlet, pre-compressed airflow can be efficiently captured, and the high lift-drag ratio is achieved. Shock wave sealing can be achieved through the three three-dimensional inward turning air inlet channels, and all flow capturing is achieved. The pneumatic and geometric coupling of the waverider precursor and the three channels can be realized through the'flow direction double waverider 'principle, and the waverider characteristics of the waverider precursor and the three channels cannot be damaged.
基于流向双乘波原理的乘波前体/三通道进气道一体化设计方法,属于高超声速飞行器内外流一体化设计领域。其本质是建立乘波前体外流场和内转进气道内流场之间的联系,设计和研究内外流一体化轴对称基准流场模型,在基准流场中采用密切流场,通过流线追踪设计型面,从而发展乘波前体/进气道一体化新型设计理论。乘波前体的前缘和三个内转进气道唇口前缘均能贴附在激波面上,乘波前体作为进气道的预压缩面,不仅可高效捕获预压缩后的气流,且具有高升阻比。三个三维内转进气道均能实现激波封口,获得全部流量捕获。通过“流向双乘波”原理可以实现乘波前体和三通道气动上和几何上的耦合,且不会对两者乘波特性造成破坏。
