The invention discloses a sweepforward canard flying wing aerodynamic layout unmanned aerial vehicle, and the unmanned aerial vehicle comprises a vehicle body, main wings, edge strip wings, full-motion canard wings and full-motion vertical tail wings, wherein the main wings, the edge strip wings, the full-motion canard wings and the full-motion vertical tail wings are connected with the vehicle body, and the full-motion canard wings and the full-motion vertical tail wings are arranged at the front end of the vehicle body; the main wings and the edging wings are arranged at the rear end of thefuselage and are of an integrated structure; the flying wing aerodynamic layout, the canard aerodynamic layout and the sweepforward wing aerodynamic layout are fused, so the flying performance of thefixed-wing aircraft is well improved, the contradiction between sweepforward wing aerodynamic divergence and structural quality is solved, the problems that the maximum lift coefficient Clmax of the flying wing layout is too small and the pitching maneuverability is poor are solved, and the problem that a canard layout structure is complex is solved; the maneuvering performance, the loading capacity, the low-speed performance and the like of the canard layout structure are greatly improved, and compared with a conventional aerodynamic layout fixed-wing unmanned aerial vehicle, the effective load of the canard layout structure is increased by 20%, the take-off and landing distance is shortened by 35%, the maximum flight speed is increased by 5%, and the minimum flight speed is reduced by 30%.
本发明公开了一种前掠鸭式飞翼气动布局无人机,包括机身以及与机身连接的主机翼、边条翼、全动鸭翼及全动垂直尾翼,所述全动鸭翼和全动垂直尾翼设于机身的前端,主机翼和边条翼设于机身后端,所述主机翼与机身为一体化结构,通过将飞翼气动布局、鸭式气动布局以及前掠翼气动布局进行融合,使固定翼飞行器的飞行性能得到较好的改善,解决了前掠翼气动发散与结构质量的矛盾,解决了飞翼布局最大升力系数Clmax过小与俯仰操纵性差的问题,解决了鸭式布局结构复杂的问题,并在其机动性能、载重能力、低速性能等方面均有着重大改善,其有效载荷相较于常规气动布局固定翼无人机的升力将提高20%,起降距离缩短35%,最大飞行速度提高5%,最小飞行速度降低30%。
