The invention discloses a long-endurance wind energy unmanned aerial vehicle. A plurality of reversible motor assemblies and propellers are mounted on semi-flexible and semi-rigid arched wings of the long-endurance wind energy unmanned aerial vehicle; during normal flight, the reversible motor assembly serves as a motor to drive the propeller to rotate to generate tension, and in the power generation mode, the reversible motor assembly serves as a generator to convert mechanical energy of the propeller driven by wind power into electric energy; according to the specific mode, the unmanned aerial vehicle flies against wind, climbs to a certain height by means of wind power and then dives downwards to generate power and charges a storage battery, the processes of upwind climbing and diving power generation are repeated, and high-altitude long-endurance flight of the unmanned aerial vehicle can be achieved; due to the fact that the flying process and the power generation process are carried out in turn, power is generated while being used, a large amount of stored power is not needed for standby application, the carrying amount of a storage battery can be greatly reduced, meanwhile, due to the fact that the unmanned aerial vehicle can fly in the space with the high air density and the high wind speed, the wings can generate larger lift force, the effective load can be greatly increased, and the efficiency of the unmanned aerial vehicle can be fully exerted.
本发明公开了一种长航时风能无人机,其半柔性半刚性的拱形机翼上装有多个可逆电机组件及螺旋桨;正常飞行时,可逆电机组件作为电动机驱动螺旋桨旋转产生拉力,发电模式下,可逆电机组件作为发电机将风力驱动的螺旋桨的机械能转化为电能;具体方式是无人机逆风飞行借助风力爬升至一定高度然后向下俯冲进行发电并充电到蓄电池,重复进行逆风爬升及俯冲发电过程,便可实现无人机的高空长航时飞行;由于飞行过程与发电过程轮流进行,电力是边用边发(电),无需大量储电备用,故可大大减少蓄电池的携带量,同时由于无人机可在空气密度高且风速高的空间飞行,机翼可产生更大的升力,故可大幅增加有效载荷,充分发挥无人机的效能。
