摘要
为筛选优化高能燃料空气炸药(FAE)的配方组分,以石油醚、环氧丙烷和乙醚作为液体燃料,硝酸异丙酯和硝基甲烷作为液体敏化剂,金属铝粉作为固体组分,通过EXPLO5计算软件比较了不同配比FAE的爆炸压力和爆炸温度,并在无约束条件下进行了液体和液固FAE配方的云雾爆轰实验,对爆炸场、温度场等参数进行了毁伤效果分析,并量化评估了各体系的热毁伤、超压毁伤的效果。结果表明,石油醚、环氧丙烷与硝酸异丙酯混合的混合液体FAE,在石油醚质量占比55%~70%条件下,爆轰性能上表现较优。液固混合FAE中液固比例为1∶1条件下具有较良好的爆轰性能,并在无约束云雾分散实验中表现出最佳的云雾分散状态。两种体系的FAE配方在1 kg的二次起爆药量下云雾爆轰可以稳定反应,能达到爆轰状态,且在毁伤能力均具有较优效果。
To select and optimize the formulation components of high-energy Fuel Air Explosive(FAE),petroleum ether,propyl-ene oxide,and ethyl ether(liquid fuel),isopropyl nitrate and nitromethane(liquid sensitizer),and metallic aluminum powder(solid component)were used as the research objects.The explosion pressure and explosion temperature of FAE with different composition ratios was investigated by EXPLO5 calculations.The cloud burst experiments of liquid and liquid-solid FAE formula-tions were also conducted under unconstrained conditions,and the parameters such as explosion field and temperature field were analyzed for the damage effect.The results show that the mixed liquid FAE,composed of petroleum ether(mass accounted for 55%-70%),propylene oxide,and isopropyl nitrate,shows a better detonation performance.The liquid-solid mixture of FAE with a liquid-solid ratio of 1∶1 has a better detonation performance and shows the best cloud dispersion state in the uncon-strained cloud dispersion experiment.Two systems of FAE formulations in the 1 kg of secondary detonation charge under the cloud burst can be a stable response to achieve the detonation state.They all have superior results in terms of destructive capaci-ty.Also,the effects of heat damage and overpressure damage were quantified and evaluated for each system.
