Abstract

The invention discloses an unmanned aerial vehicle refueling mechanism and method. A front oil filler cap and a rear oil filler cap are arranged at the top of a head of an unmanned aerial vehicle; the near-rear end of the front oil filler cap is connected to the wall of a refueling cabin through a front hydraulic supporting rod, and the near-front end of the rear oil filler cap is connected to the wall of the refueling cabin through a rear hydraulic supporting rod; a refueling connector is fixed to the inner side of the rear oil filler cap, and the front hydraulic supporting rod and the rear hydraulic supporting rod are controlled by the refueling controller. When the unmanned aerial vehicle is refueled, the refueling controller firstly opens the front oil filler cap and then opens the rear oil filler cap, so that the refueling connector extends out of the refueling cabin together with the oil filler cap for refueling.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle and aerial refueling, in particular to an unmanned aerial vehicle refueling mechanism and refueling method. Background technique [0002] UAVs do not require a pilot and can fly at high altitudes for a long time, which has great advantages over manned aircraft. However, due to its small size, limited fuel, and mission load, the flight range of UAVs is severely reduced, which cannot meet the mission requirements. The development of unmanned aerial vehicles that can be refueled in the air has become an urgent task at present. At present, there is no mature UAV refueling technology. Only the refuelable UAV in the United States has just successfully tested and completed aerial refueling. The refueling method is hard tube refueling. This kind of hard pipe refueling method is only mastered by foreign countries, and the domestic method is still the form of hose refueling, so the UAV ref...
