The invention discloses a supersonic stealth unmanned aerial vehicle with pneumatic stealth integrated design, and belongs to the field of aircrafts. According to the unmanned aerial vehicle, a front-edge sweepback medium-single wing design is adopted; V-shaped empennage layout is adopted; single-engine propulsion and back-covering separation passage-free clam type air inflow channel scheme are adopted. The pneumatic stealth integrated design of the unmanned aerial vehicle comprises: supersonic speed Sears-Haack transonic speed area law fuselage design; small-aspect-ratio wing empennage design; supersonic airfoil selection; and high-total-pressure-recovery-coefficient separation passage-free clam S-curved air inflow channel design. Ailerons are arranged on the inner sides of the wings of the unmanned aerial vehicle so as to be used for rolling control, and the empennage is a full-motion V-shaped tail and can conduct pitching and heading control at the same time. The supersonic stealthunmanned aerial vehicle provided by the invention has good low-resistance characteristics and stealth characteristics in subsonic, transonic and supersonic ranges.

    本发明公开了一种气动隐身一体化设计的超音速隐身无人机,属于飞行器领域。该无人机采用前缘后掠中单机翼,V形尾翼布局,单发推进、背覆式无隔道蚌式进气道方案。该无人机的气动隐身一体化设计包括:超音速Sears‑Haack跨音速面积律机身设计;小展弦比机翼尾翼设计;超音速翼型选择;高总压恢复系数的无隔道蚌式S弯进气道设计。无人机的机翼内侧设副翼进行滚转控制,尾翼为全动V尾,可同时进行俯仰和航向控制。本发明提出的超音速隐身无人机在亚跨超范围内具有良好的低阻特性与隐身特性。
