防空指令修正弹有控弹道仿真

Control Trajectory Simulation of Command Correction for Aerial Defense

防空指令修正弹药,设计中为满足多组、多发同时修正的作战需求,拟采用控制修正指令仅发送一次的修正方式。针对此种防空指令修正弹药的特点和采用以继电式舵机为修正机构的限定条件,应用周期平均力分析了继电式舵机的修正机理,建立了有控段弹道模型,研究了启控时间,舵机修正力的大小、方向及与之对应的换向角的计算方法,探讨了时间误差所包含的因素。最后基于蒙特卡洛法给定弹道偏差,对有控弹道进行了数值仿真。结果表明按照所设计修正方案,弹道修正曲线符合预期效果,为其工程化提供了理论参考。

In order to satisfy tactics need, Command Trajectory correction planed to send the control command only once in the beginning. Considering the character of this correction tactics and relay rudder, relay rudder correction principle was analyzed based on period-average-force, the control Trajectory model was built, the control startup time, correction force value, direction and rudder change angle were researched, the time error factor was discussed. Simulation code was written based on model and Monte Carlo method. The results meet the expectation, which can refer for project.
