摘要 利用一次起爆方式进行了镁粉和硝酸异丙酯组成的液固燃料空气炸药(Fue l-A ir Exp los ive,FAE)的静爆试验,在获取试验数据的基础上,通过计算分析研究了FAE爆轰后冲击波的作用特点和超压场的变化规律,并与常规炸药TNT,RDX和钝黑铝进行了对比分析,得出了冲击波超压和冲量随距离变化的关系式.结果表明,燃料空气炸药装药爆轰特点与常规炸药不同,其爆轰反应区远比常规炸药大得多.在距离爆心一定的距离内,FAE爆轰时比常规炸药的正压作用时间长,比冲量大. A static explosive experiment has been made on solid-liquid double composite fuel-air explosive (FAE) (comprising Mg powder and isopropyl nitrate) after primary initiation. The running character of shock wave and the changing rule of overpressure space after FAE detonation have then been studied based on data analysis. Comparison on the explosion desensitized RDX-A1 enables the authors to obtain the character of FAE with that of TNT, RDX, and relation between overpressure and specific impulse varying with distance. The authors have proved that the detonation reaction range FAE is greater than conventional explosives. In a certain distance from explosive center, the action time of FAE positive pressure is longer than conventional explosives and its specific impulse is greater than conventional explosives.
