摘要:
根据大口径榴弹炮复杂装药结构的特点,将膛内流域分为4个区:燃气区、管状药区、基本药包粒状药区与附加药包粒状药区,每个区分别推导质量、动量与能量守恒方程,建立了多相流内弹道理论模型。结合工程背景,数值预报了弹丸运动加速度变化规律,为弹丸设计提供理论指导。与部分试验结果比较表明,数值计算结果与试验结果一致性很好,预测结果是可靠的。数值预报给出内弹道循环过程详细结果,对于指导装药设计、身管设计都具有重要意义。
Abstract:
Accor ding to complex pr opellant charge const ruct ion in the larg e calibre how itzer , a f low r eg io n in a g un is divided into 4 reg io ns: burning gases, st ick propel lant s, gr ain propellant s in main bag and gr ain propellant s in addit ional bag. T he conservat io n equat ions of mass, momentum and energ y are derived in each region, and mult i-phase flow interior ballistic models are established. Against the engineering backgr ound, the project ile mov ement acceleratio n in a lar ge calibre howit zer is pr edicted by numerical simulat ion, w hich of fers the oret ical g uide fo r project ile design. The computed result is in go od agreement w ith ex perimental result s. Numerical predict io n describes the interior ballist ic cir culatio n in detail, w hich is o f significance in charge design and tube desig n.
