摘　　要：针对膨胀波火炮的发射性能及不同因素对发射性能的影响规律进行了研究分析。基于膨胀波火炮的发射机理,建立了膨胀波火炮两相流内弹道模型,给出了相应的数值求解方法。通过与同口径闭膛火炮内弹道过程的对比计算,分析了膨胀波火炮的发射性能,得到了装填条件、打开时机和后喷结构参数等因素对发射性能的影响规律。The launch property of the rarefaction wave gun and some influences of different factors on the launch property were studied.The two-phase flow interior ballistic model was established based on the launch mechanism of the rarefaction wave gun.The MacCormack difference scheme was used in numerical calculations.Compared with the interior ballistic process of a closed chamber gun with the same caliber,the launch property was discussed in detail,and the influence of the different factors including loading condi...
