本文对空包弹发射枪榴弹的内弹道模型进行了改进并提出了身管面积间断处理方法。计算结果与实验结果符合得很好。改进后的模型和程序对这种内弹道问题的工程应用是令人满意的。

This paper presented the technique of area-jump treatment within barrel and modification of the interior ballistic model is given for tlie barrel where the blank cartridge is used. The calculation results accords quite well with the experimental results. Tte modified model and its program are satisfactory for engineering applications of such interior ballistics problems。
