摘要
本文针对某100mm炮特殊的点火结构,建立了能够预测膛内压力波的内弹道两相流数学物理模型及计算方法.在保证最大压力和初速与实验结果一致的条件下.预测该火炮高、低、常温下的压力波.根据计算结果,压力波幅值随药温的升高而增加,且近于线性关系。
According to the characteristics of a 100mm gun with the special ignition tube,
the interior ballistic two-phase flow physical-mathematical model and its calculation
method are established in this paper, by which the pressure waves in guns can be predicted.
Under the condition that the maximum pressure and the muzzle velocity from calculation is
in agreement with those from experiment, the pressure waves under the high, normal and
low temperature for the 100mm gun are predicted. The calculation results show that the
amplitudes of pressure waves are increasing with the ascent of the initial temperature of
propellants and that the variation relation is nearly linear.
