摘要:
为了提高燃料空气炸药(FAE)爆炸威力,设计制备了不同相态的FAE,并采用光测和电测方法,开展了开放空间下FAE一次引爆对比实验研究。结果表明:固态、液固混合及液态FAE被一次引爆后,均存在引爆中心装药、抛撒燃料、点火和爆炸4个阶段,云雾存续时间均长于等质量TNT装药的相应值,随着距离增加,固态FAE爆炸场超压变化规律为“减少-增加-减少”,其值高于等质量TNT装药的相应值;液态、液固混合FAE爆炸场超压变化规律为“增加-减少”,远场超压高于等质量TNT装药的相应值。
Abstract:
In order to improve the explosion power of fuel air explosive (FAE), the FAE with different phase states were designed and prepared, and the comparative experimental study on single ignition of FAE in open space was carried out by using the optical and electrical measurement methods. The results showed that after single ignition of solid FAE, liquid-solid mixing FAE and liquid FAE, there all exist four stages including ignition center charge, fuel dispersion, ignition and explosion, and all the duration of cloud are longer than the corresponding value of TNT charge with the same mass. The change law of overpressure within explosion field of solid FAE is decrease, then increase, and then decrease with the increase of distance, and the value is higher than the corresponding value of TNT charge with the same mass. The change law of overpressure within explosion field of liquid FAE or liquid-solid mixing FAE is increase and then decrease, and the overpressure within far explosion field is higher than the corresponding value of TNT charge with the same mass.
