通过对某飞翼飞机输油顺序的研究,分析了在不同输油顺序下飞机重心的变化情况及在不同重心位置下升降舵偏转角和飞翼飞机的配平状况。通过对最小配平阻力和飞机最佳重心位置的研究可知,改进飞机的输油顺序,可以增加飞机的巡航时间并改善飞机的操纵能力。 Based on the research on the sequence of fueling of a flying-wing aircraft, the change of the center of gravity of the aircraft and the deflection angle of the elevator under different gravity centers and the balance of the flying-wing aircraft are analyzed. Through the study of the minimum trim resistance and the optimal center of gravity of the aircraft, it can be seen that improving the order of oil transportation can increase the cruising time of the aircraft and improve the handling ability of the aircraft.
