The Investigation about Improving Impact Point Dispersion of Rocket-projectile Using Lateral Pulse Jets

文中对利用侧向脉冲力减小火箭弹散布的技术进行了研究。一组脉冲发动机安装在火箭弹的头部,在垂直于弹轴的平面内环向均匀分布,可提供多次、恒定的控制力,以减小火箭弹的落点散布。通过模型弹的外弹道仿真对比,落点的横向散布距离减小了54.8%及73.3%,说明文中提出的脉冲点火控制算法是可行的。

In this thesis, the technique that the impact point dispersion of a rocket-projectile can be reduced with a ring of appropriately sized lateral pulse jets has been investigated. A number of jet motors are located on the nose of the rocket-projectile, and can provide a set of constant correct forces, in order to reduce the impact point dispersion. An individual jet motor is distributed equably on vertical plane with the projectile axis. In the example case, the yaw dispersion error is reduced 54.8% or 73.3%. A according to exterior ballistic numerical simulation's result, the feasibility of the method about lateral pulse jet motor firing control logic has been proved.
