The invention discloses a multi-wing flying wing type solar unmanned aerial vehicle, which comprises an undercarriage, a pod and a plurality of wings, the wings are arched wings with spanwise camber and are arranged according to the front, middle and rear positions, and the middle wing is different from the front and rear wings in height; the plurality of wings are connected together through the bracket, and the wingtips of the front and rear wings are connected through the inter-wing beam; solar cell panels are laid on the surfaces of the wings, and a plurality of electric propellers are installed on the front edges of the wings. The wings are all formed by air punching of the air chambers formed by combining rigid frameworks with flexible soft materials, the weight of the wings is greatly reduced, the effective load is remarkably increased, and meanwhile the wings have the super-high aspect ratio and the high lift-drag ratio; particularly, the defects that a traditional straight single-wing flying wing type unmanned aerial vehicle is low in bending resistance and torsion resistance and complex in flight control are overcome through the multiple arched wings in spatial layout; the flying wing type solar unmanned aerial vehicle can perform low-power hovering at a horizontal wind speed, and is very suitable for long-term hovering flight in a stratosphere high-wind-speed environment.
本发明公开了一种多翼的飞翼型太阳能无人机,包括起落架、吊舱及多个机翼,机翼均为具有展向弯度的坦拱形机翼,按前中后位置排布,中间机翼与前后机翼的高度不同;多个机翼通过支架连接在一起,前后机翼的翼尖通过翼间梁相连;机翼表面均铺设太阳能电池板,机翼的前缘均安装多个电动螺旋桨。本发明的机翼均采用刚性骨架结合柔性软质材料构成的气室经空气冲压而成,大幅降低了机翼重量,显著增加了有效载荷,同时具有超大展弦比及高升阻比,特别是空间布局的多个拱形机翼克服了传统平直单翼飞翼型无人机抗弯扭能力低下以及飞行操控复杂的缺陷;该飞翼型太阳能无人机可在水平风速下进行低动力盘旋,非常适合平流层高风速环境下的长期滞空飞行。
