| 摘 要： | 为了简化埋头弹的内弹道模型，将埋头弹内弹道过程分为两个阶段。结合经典内弹道和高等内弹道理论，并应用两相流体力学模型和计算流体动力学技术，分别建立了埋头弹传火管零维模型和身管内一维两相流模型，并利用MATLAB软件进行了数值模拟，获得了内弹道参数在弹后空间的分布情况，为分析埋头弹内弹道性能提供了一种新的建模方法，为埋头弹装药结构的修正和优化提供了理论指导。

| Abstract: | In order to simplify the interior ballistic model of Cased Telescoped Ammunition(CTA),divided the interior ballistic process into tow stages.Combined with the classical interior ballistic theory and the modern interior ballistic theory,a mathematical model composed of igniter squid zero dimension model and one dimension two-phase flow interior ballistic model of Cased Telescoped Ammunition simulated by using the two-phase flow method and computational fluid dynamics is established,and is confirmed with MATLAB software.Showed the distribution in space after the shell of ballistic parameters,a new model creation method of analyzing interior ballistic performance of cased telescoped ammunition is provided.Important theoretical guidance for revising and optimizing the CTA gun charge structure are provided. |
