摘要

摘要: 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70 m，在发射过载加速度为100 km/s2 的情况下，孔隙压缩产生的最高温度约573 K。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。

Abstract: 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 has been established.
