The invention discloses a moving platform ultra-short take-off and landing fixed-wing unmanned aerial vehicle, which is used for ultra-short landing on a moving platform target object in an area with the fuselage length less than ten times, the unmanned aerial vehicle comprises a W wing and a sweepback canard wing, the W wing is formed by fusing wing bodies, the W wing comprises a sweepback inner wing and a sweepforward outer wing extending outwards from the sweepback inner wing, and the sweepback canard wing is formed by fusing the sweepback inner wing and the sweepforward outer wing. Wing roots of the sweepback inner wings extend inwards and are fused with the S-shaped lifting body to form machine body edge strips, and the sweepback inner wings and the S-shaped lifting body are fused to form a wing body fusion body. A multi-vortex-system coupling flow pattern is formed by the nose lip line, the sweepback canard, the aircraft body edgings and the W wings, so that the large-attack-angle control efficiency of the sweepback trapezoidal canard is improved, and the canard resistance in a cruising state is reduced; the sweepback canard wings are relatively high on the W wings by virtue of the S-shaped lifting body fuselage design, so that the flowing on the upper surface of the wing-body fusion body in a cruising state can be improved; vortex lift force of the wing body fusion body is enhanced by stable vortexes generated by the body edgings, and the high-attack-angle stall characteristic of the unmanned aerial vehicle can be remarkably improved.
本发明公开了一种动平台超短距起降固定翼无人机,用于在十倍以下机身长度的区域超短距降落在动平台目标物体上,所述无人机包括翼身融合形成的W翼以及后掠鸭翼,所述W翼包括后掠内翼以及由后掠内翼向外延伸的前掠外翼,后掠内翼的翼根向内侧延伸与S型升力体机身融合形成机身边条,后掠内翼与S型升力体机身融合形成翼身融合体。本发明通过机头唇线、后掠鸭翼、机身边条、和W翼形成多涡系耦合流型,提高后掠的梯形鸭翼的大迎角操控效能,并减小巡航状态鸭翼阻力;后掠鸭翼借助S型升力体机身设计相对高置于W翼,可改善巡航状态翼身融合体上表面流动;机身边条产生的有利稳定涡流强化翼身融合体涡升力,可显著提高无人机大迎角失速特性。
