The invention discloses a design method of a high-ultrasonic-speed skating and patrolling integrated double-waverider aircraft, and relates to a hypersonic-speed aircraft forebody/air inlet channel. According to the large-range efficient flight requirement of a novel trajectory scheme of a hypersonic gliding-cruising aircraft, a gliding and patrol integrated hypersonic aircraft configuration is designed and comprises a cruising-level aerodynamic profile based on the flow direction double waverider principle and a gliding-level aerodynamic profile based on the minimum wave resistance outer cone approximation theory. The two stages of pneumatic molded surfaces are subjected to waverider design of respective design points and are combined in a symmetrical form, the gliding-stage pneumatic molded surface on the back of the aircraft in the gliding reentry stage downwards performs unpowered gliding range extension, and the cruising-stage pneumatic molded surface of the aircraft in the cruising stage is overturned downwards; in a designed inner/outer flow integrated axial symmetry reference flow field, an outer waverider wall surface and an inner waverider air inlet channel which are generated through streamline tracking provide a good waverider characteristic for a cruising stage. And a new thought is introduced for realizing the design of excellent flight performance of wide speed domain and extensive airspace of the hypersonic-speed fixed-geometry aircraft configuration.

    高超声速滑巡一体双乘波飞行器设计方法,涉及高超声速飞行器前体/进气道。根据高超声速滑翔‑巡航飞行器新型弹道方案大范围高效飞行需求,设计一种滑巡一体高超声速飞行器构型,包括基于流向双乘波原理的巡航级气动型面与基于最小波阻外锥近似理论的滑翔级气动型面。两级气动型面均进行各自设计点的乘波设计并以对称的形式进行结合,滑翔再入阶段飞行器背部的滑翔级气动型面朝下进行无动力滑翔增程,巡航阶段飞行器的巡航级气动型面翻转至下,在设计的内/外流一体化轴对称基准流场中通过流线追踪生成的外乘波壁面与内乘波进气道为巡航阶段提供良好的乘波特性。为实现高超声速定几何飞行器构型的宽速域、泛空域出色飞行性能的设计引入新思路。
