摘要
炸药装药在发射条件下的安全性问题已成为高能量炸药应用的一个技术障碍,引起了各国的广泛重视。燃料空气炸药(FAE)战斗部是近年来倍受国内外关注的新概念武器。目前关于FAE装药的发射安全性特别是高过载环境下的发射安全性研究还不系统、不够深入,也没有给予足够的重视。运用爆炸力学程序Object MMIC程序分析了FAE战斗部发射过程中的应力和应力率变化规律。分析结果表明,FAE战斗部发射过程中受到的应力和应力率不同于传统的发射过程,因此,有必要建立适用于FAE武器的全新的发射安全性理论。这些研究对提高FAE战斗部发射安全性提供了依据。
The launching safety of explosive charge drastically affecting the application of high explosive should be used with care. The researchers are interested in the low cost and high efficiency of FAE （fuel air explosive） charged warhead. However, few references about the launching safety of the mixed fuel, especially under high launching load,can be found. In this paper, the pressure and pressure-rate in the mixed fuel during launching was analyzed by the explosion mechanics programming Object MMIC. The analysis shows that the pressure and pressure rate are different from those obtained from the traditional launching safety theory. Therefore,it is necessary for FAE weapon to establish a new launching safety theory by means of the innova- tive method combining the pressure wave stage with the inertia stage.
