The invention discloses an aircraft and a fuel tank thereof, the fuel tank comprises a plurality of mutually independent chambers, and the chambers are mutually communicated. By the adoption of the scheme, the chamber walls of all the chambers can block liquid fuel, the gravity center change of the liquid fuel can be well overcome when an aircraft is in the action postures such as pitching, rolling and yawing, and then strenuous movement of the liquid fuel in the fuel tank and impact on the walls of the fuel tank can be reduced; therefore, the influence on the flight stability can be reduced. In this way, the operation system of the aircraft can also become simple; moreover, the fuel tank is usually made of metal materials such as aluminum materials, when a plurality of cavities exist, the number of plate wall structures of the fuel tank is increased, correspondingly, the heat dissipation performance can also be improved, rapid cooling of return liquid of a starting system is further facilitated, and the liquid temperature stability of liquid fuel in the fuel tank can be better guaranteed.
本发明公开一种飞行器及其燃料箱,其中,该燃料箱包括若干相互独立的腔室,各所述腔室相互连通。采用这种方案,各腔室的腔室壁可以对液体燃料进行阻挡,能够较好地克服飞行器在处于俯仰、滚转、偏航等动作姿态时液体燃料的重心变化,进而可以减少液体燃料在燃料箱内的剧烈运动以及对于燃料箱壁的冲击,从而可以减少对于飞行稳定性的影响。如此,飞行器的操作系统还可以变得简单;并且,上述的燃料箱通常为金属材质,如铝材质等,在存在多个腔室时,燃料箱的板壁结构增多,相应地,散热性能也可以增加,还有利于发动系统回液的快速冷却,能够更好地保证燃料箱内部液体燃料的液温稳定性。
