摘要:
对于新近问世的膨胀波枪炮,提出了其发射过程的四阶段物理模型,采用准一维准两相流理论建立了其发射过程动力学模型,以14.5 mm膨胀波弹道枪为对象进行了数值仿真计算,将计算结果与普通闭膛枪炮的内弹道过程进行了对比,得出了膨胀波枪炮发射中的各种特征参量变化规律以及膛尾打开时刻等关键参数。计算表明:14.5 mm膨胀波弹道枪在基本不降低枪炮初速的前提下能减少59%的后坐动量。
Abstract:
Afour-stage physical model which describes propulsion process of  the newly developed rarefaction wave gun( RAVEN) is put forward, and a dynamic model of the rare faction wave gun ( RAVEN) is made using quasi one-dimensional quasi two-phase flow theory. A14. 5mm rarefac-tionwave test gun is taken for numerical simulation and its performance is compared with that of a traditional close bree chgun. A rule of variation of RAVEN’s characteris ticparameters is worked ou.t It is found that the14. 5mmRAVEN has the potential of reducing 59%of the recoilmomen-tum without compromising them uzzlevelocity of the projectile.
