摘　　要：针对爆炸分散型子母式发烟弹,研究建立了母弹飞行弹道、子弹抛撒内弹道和子弹飞行弹道模型,运用Matlab软件,分析计算了最小射程条件下弹道诸元变化规律,基于横向间隔的目标函数法,确定了子弹的阻力系数及弹道参数,即最小射程条件下最佳抛撒点参数、罐体抛撒时间和罐体阻力系数。通过三罐轴向并联一次性起爆试验,证实了子弹横向间隔的合理性及全弹道抛撒方案的正确性,可为后续子母式发烟战斗部设计提供技术支撑。Aiming at the explosively dispersed cluster-type smoke bombs,the models for the flight trajectory of the mother bomb,the internal trajectory of the bullet ejection and the flight trajectory of the bullet have been researched and established.Using Matlab software,the law of ballistic changes under the condition of minimum range was analyzed and calculated.Based on the objective function method of lateral spacing,the ballistic parameters and drag coefficient of the bullet,that is,the parameters of the best throwing point under the minimum range condition,the throwing time of the tank and the drag coefficient of the tank were determined.Through the one-time detonation test of three tanks in axial parallel connection,the rationality of the lateral spacing of the bullets and the correctness of the full-ballistic dispersal plan were verified,which provided technical support for the subsequent design of the cluster-type smoking warhead.
