介绍了一种新的气动武器，并给出了其结构和工作原理，建立了其内弹道数学模型，通过Matlab对其进行了数值计算。根据数值计算结果，分析了大、小气室截面积之比、小气室初始长度、活塞质量和弹丸释放压力等发射参数变化对弹丸速度的影响，结果表明：气室截面积之比和弹丸释放压力对弹丸初速影响很显著，活塞质量和初始长度对弹丸初速影响不明显。

A new pneumatic weapon is introduced in the paper,and its structure are given.Then its ballistic mathematical model is established carrying out its numerical calculation. According to the results of numerical calculation,the influence of launch parameters is analyzed,such as,the ratio of the cross-sectional area between the larger gas chamber and the smaller gas chamber,the initial length of the smaller gas chamber,piston mass and projectile release pressure,having on the projectile velocity. The results show that the ratio of the cross-sectional area of gas chamber and the projectile relieve pressure have significant effect on muzzle velocity,but the influence of piston mass and the initial length are not obvious.
