摘要
根据模块装药火炮复杂装药结构的特点 ,考虑了隔仓及环形间隙区的作用并建立了轴对称二维两相流内弹道理论模型。数值预测结果表明 ,膛底、药室口部曲线与实验有较好的一致性。文中还给出了模块装药膛内发射过程的详细计算结果 。
This paper presents an axisymmetric two dimensional theoretical model for the interior ballistic two phase flow, based on the characteristics of the modular charge construction. Functions of the axial ullage between coupled modules and the annular ullage around the modules are taken into account. The computed results are consistent with those from experiments at the breech and the mouth chamber. Detailed results of numerical simulation are provided.
