Interior Ballistic Consistency of Serial Launch with Super-high Firing Rate

为对超高射频串联发射内弹道性能进行一致性校正,该文采用经典内弹道模型编制程序,对串联发射内弹道过程进行了数值模拟。分析了不同射击频率下装填条件对内弹道性能的影响,得到了最大膛内压力和初速的定量修正公式。结合定量修正公式和数值模拟程序,对最大膛内压力和初速进行了一致性校正,得到了不同射击频率下的一致性校正结果。结果表明,联合使用定量修正公式和数值模拟程序是对超高射频串联发射内弹道性能进行一致性校正的简便而高效的方法。

In order to correct the interior ballistic consistency for the serial launch with the super- high firing rate, the interior ballistic process is simulated by the code based on the classic interior ballistic model. The effects of load conditions on interior ballistic performances are analyzed under different firing rates. The modified quantitative formulas of the maximum chamber pressure and the muzzle velocity are obtained. Their consistency correction of the maximum chamber pressure and the muzzle velocity is performed by modified formulas and the simulation code. The corrected results under different firing rates show that combinely using modified formulas and the simulation code is a simple and efficient way to correct the interior ballistic consistency for the serial launch with the super-high firing rate.
