Hydrodynamic force based unmanned aerial vehicle (uav) replenishment device

The invention discloses a hydrodynamic force based unmanned aerial vehicle (uav) replenishment device which is mainly applicable to the field of seaborne replenishment and is characterized by mainly comprising a water surface engine compartment, a connecting hose and a fuselage, wherein an engine is arranged in the water surface engine compartment, provides power for the entire replenishment device, and pumps seawater, the pumped seawater is conveyed to the fuselage by the connecting hose and then is sprayed out through a spray tube to generate thrust and provide power for flight of the fuselage. An object loading platform is arranged on the fuselage and used for carrying and transporting seaborne goods and materials. The hydrodynamic force based unmanned aerial vehicle (uav) replenishment device solves the problems that the existing replenishment device for seaborne ships is complicated in structure, longer in previous preparation time, liable to influence of sea wave and sea breeze, and has higher requirements for synchronization of two ships and has the advantages of being high flexibility and speed and being suitable for replenishment.
