The invention relates to an unmanned aerial vehicle fuel oil system which comprises a main oil tank, a fuel oil tank and a fuel oil tank. The auxiliary oil tank is arranged in the fuselage of the fixed-wing unmanned aerial vehicle and is spaced from the main oil tank in the heading direction, and the auxiliary oil tank is in fluid connection with the main oil tank and supplies oil to an engine of the fixed-wing unmanned aerial vehicle through the main oil tank; wherein the main fuel tank is located at 0%-25% of the spanwise direction of the wings, and the auxiliary fuel tank is located at the position of 40%-70% of the length of the fuselage from the nose. Through the arrangement mode of the fuel oil system of the unmanned aerial vehicle, the gravity center position of the fixed-wing unmanned aerial vehicle can be changed between 23% MAC and 31% MAC. Therefore, the shape of the fuel tank is designed and the position of the fuel tank is arranged according to the constraint conditions, and the fuel consumption gravity center curve is controlled, so that the subject gravity center requirement of scaling flight can be met. In addition, the invention further relates to the fixed-wing unmanned aerial vehicle.

    本发明涉及一种无人机燃油系统,包括:主油箱,主油箱设置在固定翼无人机的机翼中;副油箱,副油箱设置在固定翼无人机的机身中并且在航向方向上与主油箱间隔开定位,副油箱流体连接到主油箱并且经由主油箱为固定翼无人机的发动机供油;其中,主油箱位于机翼展向的0%~25%,而副油箱位于机身的长度的从机头开始的40%~70%的位置。通过这种无人机燃油系统布置方式,能够使固定翼无人机的重心位置在23%MAC~31%MAC之间变化。这样,通过按照以上约束条件来设计油箱形状并且布置油箱位置,实现了耗油重心曲线的控制,从而可以满足缩比飞行的科目重心要求。另外,本发明还涉及一种固定翼无人机。
