| 摘 要： | 膨胀波火炮利用弹丸在膛内运行到一定位置时提前开闩的方法，实现了在不降低弹丸初速的前提下大幅度减小火炮后坐力的目的。基于膨胀波火炮后喷装置的工作特性，对两种不同打开方式进行了讨论，着重对惯性炮尾式膨胀波火炮进行了物理模型和经典内弹道模型建立，并进行数值仿真。最后根据经验公式估算的惯性炮尾开闩行程，利用反推法计算了惯性炮尾式膨胀波火炮膨胀波在身管内的传播速度和行程，进而获得了惯性炮尾最佳打开时机和开闩行程。

| Abstract: | By means of suddenly opening breechblock while projectile was traveling to a special location in barrel,the aim to considerably reduce recoil momentum under the presupposition condition of without decreasing the muzzle velocity of projectile was realized in the rarefaction wave gun (RAVEN).Base on operational properties of RAVEN vent mechanism,two kinds of different breechblock opening mode were discussed,physical and classical interior ballistics models of inertial breech RAVEN were emphatically set up,and... |
