模块装药膛内火焰扩散过程的理论研究

THEORETICAL STUDIES OF FLAMESPREADING PROCESSES OF MODULAR CHARGES

模块装药结构的复杂性增加了膛内发射过程实验诊断的难度与不可预计性．本文建立了两相流内弹道模型，考虑了模块运动以及初始装填分布等多方面因素．利用该模型计算结果与实验结果吻合得较好．该模型及程序可以用来模拟模块装药内弹道早期点火、火焰扩散、装药床的移动以及压力波的发展过程，从而为这类装药的设计提供了理论依据．

The complexities of modular charges increase the difficulties of experimental diagnosis and prediction during the launching processes. Many factors, such as the movement of modules and the initial position, are taken into account in the interior ballistics models of two phase flow. The results are consistent with those of experiments. The models and code allow to simulate ignition, the flamespreading processes, the displacement of charges and the development of pressure during the early ballistics cycle, and these can provide the direction for this kind of charge designs.
