The invention relates to the technical field of aviation and new energy, in particular to a hydrogen energy ground-effect amphibious unmanned aerial vehicle which comprises a vehicle body, wings, buoys, buoy frames, a vertical power device, a horizontal power device support and a horizontal power device nacelle. According to the invention, the defect of low power density of a hydrogen fuel cell is made up through ground-effect flight, and the defect of large volume of a hydrogen storage tank is overcome through the design that the hydrogen storage tank is used as the buoy during overwater operation, so that the ground-effect effect of the unmanned aerial vehicle is enhanced. On this basis, through a series of means of direct force attitude control, distributed propulsion, pneumatic lift augmentation and the like, the unmanned aerial vehicle can not only fly at ultra-low altitude and low altitude in a ground-effect area of a water area, but also sail on the water surface, the advantage of high energy density of a hydrogen fuel cell system is fully played, and the cruising ability and the loading capacity of the unmanned aerial vehicle are improved.

    本发明涉及航空技术和新能源技术领域,尤其涉及一种氢能地效两栖无人机,包括,机身、机翼、浮筒、浮筒架、垂直动力装置、水平动力装置支架、水平动力装置短舱,通过对机翼有效地分布提供地效升力,并自动平衡俯仰力矩,浮筒阻挡地效飞行时所述无人机下方的气流向两侧逃逸增强地效作用,本发明通过地效飞行来弥补氢燃料电池功率密度低的缺陷,通过水上运行,用储氢罐来作为浮筒这样的设计来回避储氢罐体积大的缺点,在此基础上通过直接力姿态控制、分布式推进、气动增升等一系列手段,可以使无人机既能在水域地效区超低空、低空飞行,又能在水面航行,充分发挥氢燃料电池系统能量密度高的优势,提升无人机的续航能力和载重性。
