以某大口径榴弹发射器为例，对采用外加药室容积的变初速技术进行分析。利用内弹道原理对变初速方案进行建模；利用Runge-Kutta法，通过MATLAB软件进行变初速后的内弹道仿真。仿真结果说明了外加药室容积在不同位置时对弹丸初速的影响规律及影响程度，对变初速技术的工程应用具有一定的指导意义。

Taking a large-caliber grenade launcher as example , this paper studied the variable initial velocity technology using additional chamber volume . The model of variable velocity program was set up by the interior ballistic principle . Based on Runge-Kutta algorithm ,the simulation of interior ballistic after variable velocity was carried out in MATLAB .The results show the effect of the position of additional chamber volume on muzzle velocity .It has certain guiding significance to engineering applications of variable initial velocity technique .
