A high-altitude solar parafoil unmanned aerial vehicle comprises a parafoil, a hanging rope and a pod. The parachute wing serves as a lifting surface of the unmanned aerial vehicle and adopts a high aspect ratio aerodynamic layout, a circle of rope surrounds the periphery of the parachute wing and is used for stabilizing the appearance structure, the chordwise camber appearance of the parachute wing is kept through three carbon fiber strip-shaped wing ribs penetrating front and back, two control carbon strips are installed on the rear edge of the parachute wing, and the control capacity is provided on the basis of keeping the spanwise appearance; the two carbon fiber strip-shaped wing ribs on the two sides are respectively connected to the midpoint positions of the two control carbon strips; a solar cell array is laid on the surface of the parasol wing, provides flight power and charges a battery in the pod; the parasol wing is connected with the pod through a plurality of hanging ropes, and two of the hanging ropes are connected to the spanwise center positions of the control carbon strips respectively; an energy storage battery, a task load and a flight control unit are installed in the pod, propellers are installed outside the pod, and the flight control unit controls the propellers to work. The weight of the aircraft is greatly reduced, the flight height is increased, and the long-endurance performance is improved.
一种高空太阳能伞翼无人机,包括:伞翼、吊挂绳索和吊舱。伞翼作为无人机的升力面采用大展弦比气动布局,伞翼外围环绕一圈绳索用于稳定外形结构,通过三根前后贯穿的碳纤维条状翼肋保持伞翼弦向的弯度外形,伞翼后缘装有两根控制碳条,保持展向外形的基础上提供控制能力;且两侧的两根碳纤维条状翼肋分别连接到两根控制碳条的中点位置;伞翼表面铺设有太阳能电池阵,提供飞行动力并且为吊舱中电池充电;伞翼通过多根吊挂绳索与吊舱连接,其中的两根绳索分别连接在控制碳条的展向中心位置;吊舱中安装有储能电池、任务载荷和飞控单元,吊舱外部安装有螺旋桨,飞控单元控制螺旋桨工作。本发明极大减轻飞行器重量,提升了飞行高度和长航时性能。
