The invention discloses a novel canard-layout variant vertical take-off and landing fixed-wing unmanned aerial vehicle, and belongs to the field of aircrafts, wings are in a high-aspect-ratio forward-swept upper single-wing layout, and servo driving structures for controlling the wings to fold are designed and mounted at the positions close to the roots of the wings; the aircraft wing propeller can be switched between a horizontal pushing cruise mode and a vertical take-off and landing lift mode by folding the wings through the servo driving structure, and flight power of the two flight modes is provided by the same set of power, so that flight dead weight does not exist on the flight power system, and meanwhile, the flight power system is more reliable. According to the invention, the foot stool required by vertical take-off and landing is fused with the belly vertical fin and the canard with the lower dihedral angle, so that the function of the vertical take-off and landing foot stool is realized under the condition of not increasing extra structural weight and aerodynamic resistance. The canard layout variant vertical take-off and landing fixed-wing unmanned aerial vehicle has the advantages of simple structure, compact fuselage section, no flight dead weight, high aerodynamic layout efficiency, low aerodynamic resistance and the like.

    本发明公开了一种新型鸭式布局变体垂直起降固定翼无人机,属于飞行器领域,机翼为大展弦比前掠上单翼布局,靠近机翼根部位置设计安装有控制机翼折叠的伺服驱动结构,可通过伺服驱动结构折叠机翼的方式实现飞机机翼螺旋桨在平推巡航模式与垂直起降升力模式之间切换,两种飞行模态的飞行动力都由同一套动力提供,因此飞行动力系统上不存在飞行死重,同时,本发明将垂直起降所需的脚架与机腹垂尾及带下反角的鸭翼融合,在不增加额外结构重量及气动阻力的情况下实现了垂直起降脚架功能。此型鸭式布局变体垂直起降固定翼无人机具有结构简单、机身段且紧凑、无飞行死重、气动布局效率高、气动阻力低等优势。
