The invention discloses a canard flying wing aerodynamic layout unmanned aerial vehicle, and the unmanned aerial vehicle comprises main wings, full-motion canard wings, a full-motion vertical tail wing and a vehicle body, and the flying performance of a fixed wing aircraft is well improved by fusing flying wing aerodynamic layout and canard aerodynamic layout. The main wings adopt flying wing structures, so that the structural mass can be reduced, the effective lift area is increased, and the immersion area is reduced. The full-motion canard is added in front of the main wing, so that the pitching control range of the unmanned aerial vehicle is widened, and meanwhile, the maximum lift coefficient of the flying wing is increased. Compared with the performances of a conventional aerodynamiclayout fixed-wing unmanned aerial vehicle, the lifting force is improved by about 13.3%, the effective load is improved by about 8.6%, the unmanned aerial vehicle has outstanding performance in the aspect of low speed, the minimum flight speed can be reduced to 6 m/s, and the flight speed is reduced by about 37% compared with a single-flying-wing type aerodynamic layout unmanned aerial vehicle. Compared with a single-flying-wing type aerodynamic layout unmanned aerial vehicle, a pair of canard wings is additionally arranged on the structure, so that the lift-drag ratio of the unmanned aerial vehicle is reduced by about 5.25%.
本发明公开了一种鸭式飞翼气动布局无人机,包括主机翼、全动鸭翼、全动垂直尾翼及机身,通过将飞翼气动布局与鸭式气动布局进行融合,使固定翼飞行器的飞行性能得到较好的改善。主机翼采用飞翼构型,能够降低结构质量,增加有效升力面积,降低浸入面积。在主机翼前添加全动鸭翼,使无人机的俯仰操控范围得以扩宽,同时提高飞翼的最大升力系数。相较于常规气动布局固定翼无人机的升力将提高约13.3%,有效载荷提高约8.6%,并且在低速方面有着较为突出的表现,最小飞行速度可降至6m/s,比单飞翼式气动布局无人机飞行速度降低约37%。相较于单飞翼式气动布局无人机在结构上增加了一对鸭翼,使得其升阻比比单飞翼式气动布局无人机降低约5.25%。
