摘　　要：利用一维两相流理论建立了膨胀波枪炮发射过程的四阶段动力学模型,计算了14.5 mm膨胀波弹道枪、14.5 mm机枪(单发)和14.5 mm无坐力弹道枪的发射过程,分析了3种武器的内弹道特征量的变化规律.结果表明,与常规闭膛枪炮相比膨胀波枪炮在不减小弹丸初速的情况下能大幅度减小后坐;与无坐力枪炮相比膨胀波枪炮大大提高了火药利用效率和弹道效能。The four-stage dynamic model of rarefaction wave gun （RAVEN） was put forward by using one-dimensional two-phrase flow theory. A 14.5 mm rarefaction wave test gun, a 14.5 mm machine gun （single shot） and a 14.5 mm recoilless rifle were taken as the computing examples,and variation of their interior ballistic characteristic parameters were compared with each other.The research reveals that compared to orthodox close-breech gun, RAVEN reduces recoil momentum dramatically without decreasing the muzzle velocity; compared to recoilless gun, RAVEN improves gun powder propulsion efficiency as well as ballistic performance greatly.
