The invention relates to the technical field of mooring unmanned aerial vehicles, in particular to a hydrogen power mooring unmanned aerial vehicle which comprises a sky end and a ground end, a pipeline is arranged between the sky end and the ground end, and the pipeline is used for conveying fuel at the ground end to the sky end; the sky end comprises an aircraft, a fuel cell stack is fixedly mounted at the lower end of the aircraft, an avionics bin is fixedly mounted at the position, located at the lower end of the aircraft, of one side of the fuel cell stack, and a hydrogen receiving opening is formed in the lower portion of the fuel cell stack. The high-pressure hydrogen in the hydrogen cylinder just reaches the working pressure when reaching the fuel cell stack after passing through the pressure reducer at the ground end and the on-way pressure drop of the pipeline; the problems that a traditional mooring unmanned aerial vehicle with a hydrogen fuel cell energy storage system and an electric pile at the ground end is powered by a high-voltage direct-current or alternating-current cable, so that power transmission loss is large, and the weight of the cable is high are solved.
本发明涉及系留无人机技术领域,具体的是一种氢动力系留无人机,本发明包括包括天空端和地面端,所述天空端和地面端之间设置有管道,管道用于将地面端的燃料向天空端输送;所述天空端包括飞行器,飞行器下端固定安装有燃料电池电堆,燃料电池电堆的一侧且位于飞行器的下端固定安装有航电仓,燃料电池电堆的下方设置有氢气接受口,本发明利用气体在管道内的沿程压降,使得从氢气瓶中的高压氢气通过地面端的减压器和管道的沿程压降后刚好在到达燃料电池电堆时达到其工作压强,解决了传统将氢燃料电池储能系统和电堆都在地面端的系留无人机使用高压直流或交流电缆供电带来的输电损耗大、线缆重量较高的问题。
