摘　　要：对某水下气动发射装置进行了理论分析,研究了其内弹道特性。利用数学建模方法对发射过程进行了建模并对内弹道性质进行了计算。对影响内弹道性能的3个主要参数:武器运动的初始阻力、发射阀最大开启面积和发射气瓶初始充气压强进行了分析。计算结果表明:发射管最大膛压的主要影响参数为武器运动初始阻力;而武器出管速度的主要影响参数为发射气瓶初始充气压强和发射阀的最大开启面积。An underwater pneumatic launcher was studied to analyze its interior ballistic character- istics. Using mathematical modeling method, the interior ballistic model was established. The influences of three parameters were discussed including the critical moving resistant force, the maximum open area of the launch valve and the initial inflation air-bottle pressure. The results show that the maximum chamber pressure is mainly determined by the critical resistant force, and the exit velocity of the weapon out of the launch tube is mainly determined by the initial inflation air-bottle pressure and the maximum open area of the launch valve.
