摘要
该文根据开槽管状药的装药结构特点,建立两相流内弹道理论模型.在定义了开槽管状药的肉厚与槽宽的基础上,推导出形状函数,采用差分方法求解.计算结果表明,开槽管状药透气性好,点传火容易,压力波振幅小,计算结果符合膛内射击过程的变化规律.
According to the characteristics of charge structure with slotted stick-propel-lant bundles,two-phase flow interior ballistic models are established in this paper.Bydefining 2e_1 and δ_1, the shape functions of slotted stick-propellant have been derived.Difference method is used in this paper.The calculation results show that burning gasesand flame spreading through the slotted stick-propellant charge is easy and pressurewave is small.The calculation results can represent the interior ballistic cycle in gun.
