摘要:
为研究高旋二维弹道修正弹舵控后的攻角与速度偏角的特性,通过在无控弹角运动基础上增加控制组件提供的控制力和力矩,建立了其角运动方程,对起始扰动作用、瞬时控制力作用、长时间控制力作用下的弹丸攻角、速度偏角规律进行了分析。数值计算结果表明:高旋二维弹道修正弹受瞬时控制力作用时,产生的平衡攻角、平均速度偏角的方向与瞬时控制力方向大致相反; 在固定方位舵控力长时间作用下,平衡攻角、平均速度偏角方向与控制力方向近似成180°,相差一个小的角度; 攻角运动是由舵控力产生相反方向的攻角与重力产生向右的动力平衡角合成的,该攻角运动规律将影响弹道的质心运动。研究结果为高旋二维弹道修正弹的控制策略与控制方案设计提供了理论依据与参考。
Abstract:
To study the angle of yaw,and velocity deflection angle characteristics of high-rotation two-dimension trajectory correction projectile after canards control,an angular motion equation was established by applying the control assembly to provide the control force and torque on the basis of angle motion of uncontrolled projectile. The acting laws of the action of initial disturbance,instantaneous control force and long-time control force onthe angle of yaw and velocity deflection angle were analyzed. Numerical calculations show that when the high-rotation two-dimension trajectory correction projectile is subjected to the instantaneous control force,the directions of the resulting balance angle of yaw and the average velocity deflection angle motion are substantially opposite to the direction of the instantaneous control force. Under the action of the fixed canards,the directions of the balance angle of yaw and the average velocity deflection angle are approximately 180° to the direction of the control force,which is a small angle difference. The motion of angle of yaw is synthesized by the instantaneous canards control force generating the opposite direction angle of yaw and the gravity generating the rightward power balance angle,and the motion law of angle of yaw will affect the centroid motion of the trajectory. The research results provide theoretical basis and reference for the control strategy and control scheme design of the high-rotation two-dimension trajectory correction projectile.
