一次引爆云爆剂的爆炸特性后燃反应对爆炸威力的影响

The blast characteristic of SEFAEEffect of after-burning on blast power

摘要: 研究了一次引爆云爆剂(SEFAEsingle event fuel air explosive)的后燃反应(after-burning)及对其爆炸波威力的影响。通过高速摄像的记录对战斗部爆炸过程进行了分析，根据对SEFAE战斗部爆炸场参数的测试，以及爆炸威力的TNT当量计算，对战斗部壳体破裂后SEFAE所释放的能量进行了定量分析，并同试验结果进行了对比。发现强烈的后燃反应使SEFAE爆轰总能量和爆炸威力较普通炸药有很大的提高。并探讨了壳体破裂后SEFAE与空气中氧的作用机理，提出了提高云爆剂威力的途径。

Abstract: Effect of after-burning on the blast power of SEFAE was studied by analyzing blast process of SEFAE warhead recorded by a high-speed video camera. By means of data obtained from SEFAE warhead field test and their TNT equivalency calculation, energy release of after-burning was quantificationally analyzed and compared with experimental results.Comparisons show that total energy and blast power are improved due to intense after-burning. The reaction mechanism between SEFAE and oxygen in air was explored and the way of enhancing SEFAE power was proposed.
