Air vehicle adopting large-aspect-ratio double-fuselage flying wing layout

The invention discloses an air vehicle adopting a large-aspect-ratio double-fuselage flying wing layout. The air vehicle comprises two fuselages which are symmetrically arranged, the two fuselages areconnected into a wing-fuselage integrated entirety through a straight wing, and a wing-fuselage integrated outer side wing is connected to the outer side of each fuselage. According to the air vehicle adopting the large-aspect-ratio double-fuselage flying wing layout, the double-fuselage integrated layout is achieved through the straight wing, the straight wing and the double fuselages form the entirety, the structural strength of the large-aspect-ratio air vehicle is improved, and the structural weight of the large-aspect-ratio air vehicle is lower; the aspect ratio of the whole air vehiclecan be increased, the aerodynamic efficiency of the air vehicle is higher, the flying resistance is lower, and energy consumption is lower; and the area proportion of whole air vehicle lift force canbe increased, that is to sa
