The invention provides an unmanned aerial vehicle negative overload flight oil supply device and an unmanned aerial vehicle in the technical field of unmanned aerial vehicle fuel systems, the unmanned aerial vehicle negative overload flight oil supply device comprises oil conveying pipes, one-way valves, a sliding rail and a gravity oil suction nozzle, the sliding rail is installed in an oil supply cabin, and the sliding rail is sleeved with the gravity oil suction nozzle; and the oil conveying cabins on the two sides convey oil into the oil supply cabin through oil conveying pipes. The sliding rail is vertically arranged in the oil supply cabin, and the gravity oil suction nozzle is nested in the sliding rail, so that when the unmanned aerial vehicle is under the working condition of negative overload or inverted flight, the gravity oil suction nozzle can slide up and down along the sliding rail under the gravity effect and is always kept in the state of being immersed in the oil surface in the oil supply cabin, and the oil supply cabin is ensured to continuously supply oil to an engine on the unmanned aerial vehicle continuously.

    本发明提供了无人机燃油系统技术领域一种无人机负过载飞行供油装置及无人机,包括输油管、单向阀,滑轨以及重力吸油嘴,滑轨安装在供油舱内,重力吸油嘴套设在滑轨上,两侧输油舱上输油管上设置单向阀,且两侧输油舱通过输油管向供油舱内输油。本发明通过在供油舱内竖直设置滑轨,滑轨上嵌套重力吸油嘴,在无人机进行负过载或倒飞工况时,重力吸油嘴在重力效应下可沿滑轨上下滑动,并始终维持浸没在供油舱内油面中的状态,保证供油舱持续向无人机上发动机不间断供油。
