The first minus pressure difference in pressaretime profile of gan chamber is used to describe the intensity variation of pressure wave and to determine charge safety. In this paper, the relation between the degree of grain fracture and the sensitivity of pressure wave is set up. Based on interior ballistics model of twophase flow. The curves of the first minus pressure difference vs. the degree of grain fracture and the maximum breech pressure vs. the first minus pressure difference are given through numerical simulation. The research results show that the degree of grain fracture is a valuable way to evaluate the charge safety.

国内外普遍使用压力-时间曲线上的第一负压力波幅值来描述压力波的强度,用来检验装药安全性。本文将火药破碎程度与压力波敏感度联系起来,在双一维两相流内弹道模型的基础上进行数值模拟,计算得出了破碎度与第一负压力波幅值,第一负压力波幅值与最大膛底压力关系的曲线。指出用破碎度可以为装药安全性研究提供一种有价值的方法。

The charge of fuel air explosive (FAE) warhead is usually a solid-liquid mixed fuel,which contains pores to meet the usage and reservation.This study has investigated the influence of pore size on the launching safety by analyzing the physical process of the pore compressing.A criterion is proposed to distinguish the influence of pore size on charge safety in launching,and a quantitative relationship of the launching acceleration,the size of the pore and the temperature of pore in adiabatic compression...

燃料空气炸药武器战斗部装填的云爆剂一般是固液混合态,固液混合药剂介质内部难免存在孔隙,孔隙尺度对发射安全性有重要影响。通过对孔隙压缩物理过程的理论分析,研究孔隙尺度对混合燃料发射安全性的影响,建立了相应的判别准则,给出发射过载加速度、混合燃料介质内孔隙尺度、孔隙绝热压缩温度之间的定量关系,并提出了发射模拟装置设计应考虑战斗部内装药缺陷的有关参数,给出相应的设计依据。固液混合燃料介质内孔隙的尺度越小,其压缩产生的温度越低,抗过载能力就越强。如果圆形孔隙的直径为70μm,在发射过载加速度为100km/s2的情况下,孔隙压缩产生的最高温度约573K。将该值与固液混合药剂能够承受的临界温度进行比较,就可判断药剂在发射过载过程中的安全性。
