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.
