对影响无人机转动运动的两个因素的分析

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。

An Analysis of Two Factors Influencing the Rotary Motion of a Pilotless Aircraft

As a result of the interaction of the high rotational speed rotors of an aeroengine with the rotary motion of the pilotless aircraft, a gyro-torque is produced and the postures of the pilotless aircraft will be,in turn, effected by the combined action of the gyro-torque and the rotary motions of the plane in various directions. This is fhe first factor influencing the rotary motions of the pilotless aircraft. The other factor is the moment of inertia.The following subjects will be emphatically studied in this paper.(1) The effects of the gyro-torque in several special flight stages on the rotary motions of the plane;(2) The effects of the fuel content and the fuel distributions resulting from the angular variations of the plane postures on the mements of inertia and the rotary motions of the plane.
