陀螺力矩是在高速旋转的发动机转子和无人机的转动运动相互作用下产生的。在它的作用下,无人机在不同方向上的转动运动交连起来,共同影响无人机的飞行姿态。转动惯量是决定无人机的转动运动的另一个因素。本文着重研究了陀螺力矩在无人机几个特殊的飞行段落内对无人机转动运动的影响和燃料量以及无人机姿态角变化造成的燃料分布变化对无人机转动惯量以及转动运动的影响。 The gyroscopic torque is generated by the interaction between the rotating rotor at a high speed and the rotational motion of the drone. In its role, the unmanned aerial vehicles in different directions of the turning movement linked, together affect the flight attitude of the UAV. Moment of inertia is another factor that determines the rotational motion of a drone. This paper focuses on the effect of gyroscopic moment on the rotational motion of UAV in several special flight sections of UAV and the variation of fuel distribution due to the change of fuel quantity and attitude angle of UAV on the UAV’s rotational inertia and rotational motion influences.
