| 摘 要： | 描述了侧装药金属风暴武器系统内弹道的物理过程，建立了内弹道数学模型，并以发射五发某枪弹为例进行了计算。计算结果表明：射击频率越高，相邻两发弹间的内弹道过程耦合现象越明显，用于克服弹前阻力做功和侧药室分流火药燃气所消耗的能量越多，在装药条件相同的情况下各发弹之间的内弹道一致性也越差。因此，必须对这种新结构金属风暴武器系统的内弹道进行优化设计，才能达到所需的战术指标。

| Abstract: | The interior-ballistic process of the metal storm weapon system with side powder chambers is described and the mathematical model is constructed.Taking firing five bullets as an example,the computation of the above interior ballistics is conducted.The results show that the higher the firing rate is,the stronger the coupling between two conjoint bullets' interior ballistics is,the more the energy lost on overcoming the resistance of pressure in front of projectile and on propellant gas's filling side chambers is,and with the same loading conditions,the worse the bullets' consistency of interior ballistics performance is.So,to obtain the needed tactical target,an optimum design on this new weapon system's interior ballistics must be done. |
