【摘要】 采用中心爆管抛撒结构的炸开式子母弹子弹的空抛过程包括了抛撒药燃烧和各子弹运动的变化过程。当中心管内装药被点燃以后，管内压力迅速上升，达到管的爆炸应力时，管爆裂，释放出的高温、高压火药气体推动子弹离开母体，并持续加速。当火药气体压力等于大气压力时，整个空抛过程结束。本文给出了该式子母弹子弹空抛过程的理论模型，并讨论了模型的求解和计算结果。更多还原

【Abstract】 The firing process for the central tube bursting－type shrapnel involvesboth the process of powder burning and that of bullet dispersion. After the propelling charge in the central tube is ignited, gas pressure builds up rapidly and tubeexplodes once the gas pressure reaches the bursting stress. The powder gases fromthe tube impel the bullets to spread out and speed up until finally the gas pressureequals the atmospheric pressure, and the firing process is completed. The paperpresents a theoretical model of the firing process. A solution to the model and numerical results are given.更多还原
