摘　　要：在某新型超高射频火炮发射装置上,进行了金属风暴武器系统的3连发和5连发射击实验,测得实验膛压数据;建立了膛内过程的经典内弹道模型,并进行了数值仿真;仿真结果和试验结果和相近,表明该模型用于模拟金属风暴武器系统高频连发的膛内过程是可行的;利用该模型详细讨论了射击频率的变化对超高射频武器系统内弹道性能和出炮口速度的影响,并得出相关结论;这些规律对后续研究有一定借鉴作用。A firing experiment of a new super-high firing rate gun with three and five serial loading projec- tiles is tested, and get the bore pressure data. Its classical model of interior ballistics is established and a numerical simulation is conducted. Computational results are consistent with the experimental ones. This shows that the simulation of the interior ballistic process is feasible. The effect of the variation of firing rate upon the interior ballistics characteristics and the muzzle velocity were discussed in detail, and get the reg- ulations. The researches can be used for reference for subsequent research.
