Wing and unmanned aerial vehicle

The invention provides a wing and an unmanned aerial vehicle, the wing extends along a first direction, the wing comprises a wing skeleton and a wing skin, the wing skin covers the outer part of the wing skeleton, the wing further comprises a filling assembly and a plurality of partition plates, and the plurality of partition plates are arranged in the wing skeleton at intervals along the first direction; the multiple partition plates divide the interior of the wing framework into multiple oil storage spaces, the filling assembly comprises air bags, the air bags are arranged in the oil storage spaces, and the inflation volume of the air bags can be adjusted. The oil storage space is arranged in the wing framework, the situation that an oil tank occupies too much fuselage space is avoided, the space utilization rate is increased, meanwhile, the air bag with the adjustable inflation volume is arranged in the oil storage space, the inflated air bag occupies the space except for oil, and the situation that when t
