摘要
为了提高多元混合燃料的爆炸威力,采用光测和电测方法,进行了小药量无约束空间三组元固态混合燃料的野外一次引爆实验,得到了该装置条件下较优的燃料配比.实验结果表明,该多元固态混合燃料的云雾分散效果明显优于相同质量的TNT,其爆炸场超压呈衰减-增长-再衰减的变化规律,且具有非常相似的压力场分布.适当增加弹体密度可增强这种固态燃料混合物的爆炸威力.
In order to increase the explosion power of multi-component fuel mixture, a field experimental study is carried out on single ignition of a few dosage of ternary solid fuel mixture with unconfined volume dispersion, with optical and electrical testing methods. An optimized fuel mixture ratio is obtained for the test bomb. Experimental results show that the cloud dispersion effect of multi-component solid fuel mixture is better than trinitrotoluene's of the same mass. Overpressure within the explosion field of solid fuel mixture firstly decreases, then increases, and then decreases again with increase of distance, and the distribution of the overpressure field is similar. Explosion power of solid fuel mixture can be enhanced with a suitable increase of bomb density.
