The invention belongs to the technical field of aviation aircrafts, and discloses a high-aspect-ratio high-strength double-layer wing solar unmanned aerial vehicle which comprises a fuselage, wings and an empennage. The wings are transverse through wings, the number of the wings is two, the wings are an upper layer wing and a lower layer wing respectively, the fuselage is arranged between the upper layer wing and the lower layer wing, and the upper layer wing and the lower layer wing are connected through a wingtip supporting wall; solar panels are arranged on the upper surfaces of the upper-layer wing and the lower-layer wing; the empennage is arranged at tail of the fuselage. According to the double-layer united wing layout, on the premise that structural strength limitation is met, the aspect-ratio of the wings is increased to 30 or above, and the double-layer united wing layout has great significance in designing aerodynamic drag reduction of airplanes with large lift coefficients; the wingspan is reduced by 29%, the structural weight is reduced by 22%, and the mission load and the continuous flight time of the aircraft can be remarkably improved; the wings are high in bending resistance and torsion resistance; and satisfactory three-axis stability and control capability can be provided.
本发明属于航空飞行器技术领域,公开了一种大展弦比高强度双层机翼太阳能无人机,包括机身、机翼和尾翼;其中,机翼是横向一贯制机翼,机翼有两个,分别为上层机翼和下层机翼,机身设在上层机翼和下层机翼之间,上层机翼和下层机翼通过翼尖支撑墙连接;上层机翼和下层机翼的上表面都设有太阳能板;尾翼设在机身尾部。本发明的双层联翼布局在满足结构强度限制的前提下,使机翼展弦比提高到30以上,这对于设计升力系数大的飞机气动减阻,意义重大;翼展减小29%,结构重量减小22%,可显著提高飞机的任务载荷与连续飞行时间;机翼的抗弯、抗扭能力强;并能还提供满意的三轴稳定性与操纵能力。
