Study on energy output characteristics of underwater explosion of energetic microballoon sensitized emulsion explosive

  • 摘要: 将内部含有烷烃的含能微球引入乳化基质,得到一种新型乳化炸药。采用水下爆炸实验探究微球质量分数对乳化炸药水下爆炸性能的影响,得到含能微球质量分数为0.2%~7%的乳化炸药水下爆炸冲击波压力-时程曲线。依据压力结果,通过公式计算和分析得到炸药的水下冲击波峰值压力、比气泡能、比冲击波能以及比爆炸能等水下爆炸参数。实验结果表明:含能微球质量分数0.2%的乳化炸药的峰值压力最大,并且随着微球质量分数增大而下降;乳化炸药的比气泡能随着含能微球质量分数的增大先上升再下降,微球质量分数为4%的比气泡能最大;乳化炸药的爆速、比冲击波能以及比爆炸能均随着含能微球质量分数的增大而下降。
