The invention provides a supersonic jet adopting supersonic double wings and belongs to the field of novel supersonic civil aircrafts, an S-shaped bent large slenderness ratio variable cross-section fuselage is adopted as a fuselage, large-area truncated delta wings with edgings on the inner sides are adopted as inner sections of wings, engine nacelles are arranged on the upper portions of the outer ends of the wings, the small-area supersonic double wings are installed on the outer side of the engine nacelle, the tail wing adopts the design of a single vertical tail and an inverted V tail, the acoustic explosion intensity can be reduced, meanwhile, the functions of the wing inner section, the supersonic double wings and an engine nacelle supporting structure are achieved, the structural efficiency is effectively improved, and the structural weight is reduced. By the adoption of the supersonic double-wing design, it can be guaranteed that the aircraft achieves ideal environment-friendly performance and aerodynamic efficiency, the front edge and the rear edge of the supersonic double wings are movable, the problem that the performance of non-design points of conventional double wings is poor is solved, and the aircraft can have high aerodynamic performance within the flight envelope range.
本发明提供一种采用超声速双翼的超声速喷气机,属于新型超声速民用航空器领域,机身采用S形弯曲大长细比变截面机身,机翼内段采用内侧带边条大面积截尖三角翼,其外端上部布置有发动机短舱,发动机短舱外侧安装小面积超声速双翼,尾翼采用单垂尾+倒V尾设计,能够降低声爆强度,同时还起到机翼内段和超声速双翼及发动机短舱支撑结构的作用,有效提高结构效率,减轻结构重量。本发明采用超声速双翼设计,能够保证飞机实现较为理想的环保性能和气动效率,超声速双翼的前后缘可动,解决常规双翼非设计点性能不佳的不足问题,在飞行包线范围内都能具有较高的气动性能。
