【Abstract】 The passivation effect of propellant on the interior ballistic characteristics is poorly understood now.In this paper,using closed bomb vessels experiments and range shooting experiments,the passivation effect of propellant on the burning laws is studied,and the burning mathematical models of passivation propellant are established;an approach is proposed to decide the burning characteristic variables of passivation propellant,and some calculation and analysis for the interior ballistic characteristics of passivation propellant are made with these models.The calculation results can present the interior ballistic cycle in gun,and there is a good agreement between the predicted results and experimental results.更多还原
