固、液相FAE一次引爆实验研究

基于离散爆轰思想,进行了小药量无约束空间固、液相燃料空气炸药(fuelairexplosive,简称FAE)弹体的野外一次引爆实验。实验结果表明,固、液相FAE弹体的爆炸效果均明显优于等质量的TNT装药;固相FAE弹体一次引爆后的云雾分散规律和爆炸压力场分布不同于液相FAE弹体。在本实验装置条件下,固相FAE弹体的远场超压增长峰值虽未超过等质量的液相FAE弹体,但其火焰持续时间却比等质量液相FAE弹体的长。若仅考察弹体云雾最大半径,固相FAE弹体并不比等质量的液相FAE弹体优越太多,但固相FAE弹体的爆炸作用体积增大较多。

Experimental study on single ignition of solid and liquid FAE

Based on dispersed detonation idea, field single ignition experiments of unconfined volume dispersion and small dosage solid and liquid FAE bombs were done. Experimental results show that explosion effects of both solid and liquid FAE bombs are better than trinitrotoluene in the same mass. The regular rules of dispersion and distribution of the overpressure field of the solid and liquid FAE bomb are different. Under the same experimental condition, the increasing overpressure peak value within far field of solid FAE bomb is lower than liquid FAE bomb, but the continuous time of flame is longer than liquid FAE bomb. If consider the maximum radius of the dispersed cloud only, the solid FAE bomb isn't superior to liquid FAE bomb in the same mass, but the increasing action volume of the solid FAE bomb is bigger.
