摘要
希望常规高炮在拦阻射击时能够多重命中,而这种命中体制的本质是通过改变初速来达到控制弹头飞行时间,使其满足多重命中的条件,但是由于固定的、多级分号装药、次序发射,而不能在任选的瞬时实现同时命中,影响了它的适用性,因此提出一种基于底部排气弹的多重命中体制,并进行了理论分析,核心是通过控制底排延时点火时间,使弹头的飞行时间曲线满足多重命中条件,从而实现顺序发射的多发弹头同时命中目标。给出了问题求解的实现算法,此算法的核心是求解一个射角未知、终点受约束的两点边值问题,最终目的是获得同频射击条件下的底排延时点火时间。最后的仿真结果表明基于底排的多重命中体制具有可实现性,对发掘常规高炮的潜力有积极作用。
In practice, people always hope that the antiaircraft artillery can multiple hit the target in barrage fire system. The essence of the system is to control the original speed and control the flight time of the warheads for hitting the target at the same time. However, the system can not hit the target at any desired time simultaneously because of the fixed, multi-level powder charging and sequence launching. Therefore the system is unsuitable for practice application. We presented a new multiple hit system based on base bleed projectile after theoretic analysis. The kernel principle is to control the igniting time of multiple warheads, thus to attain an appropriate flight time curve for hitting the target at the same time. The implementing algorithm is given. The kernel step of algorithm is solving a two-point boundary value problem with unknown firing angle and constrained end-point, and the objective is to get the base bleed igniting time under same frequency shooting condition. The simulation showed that the multiple hit system based on base bleed projectile is realizable, which may improve the potential of antiaircraft artillery.
