A Forecast of the Inbored Fire Cvcle with a New Type of Ignition System

该文根据一种新型点火系统的装药结构特点，建立两相流内弹道数理模型。通过数值模拟，预测该炮的内弹道性能。计算结果与试验结果的一致性较好，并且符合膛内射击过程的变化规律。数值模拟结果为深入分析该炮的内弹道循环过程提供了理论依据。

In this paper,two-phase flow interior ballistic models are set up on the basis of the charge characteristics with a new type of ignition system. By using numerical simulation,this paper forecasts the interior ballistic performance of a gun. Calculated results are in good agreement with test results,and the calculated results can represent the inbored fire cvcle. The numerical simulation results can be served as the theoretical basis to analyse thoroughly the interior ballistic cycle in the gun.
