高能、含铝和温压炸药爆炸抛撒实验研究

Experimental Study on Explosion Dispersal of Thermobaric Explosive

采用高速运动分析系统观察了高能炸药、含铝炸药和温压炸药爆炸产物抛撒的过程;分析比较了三种炸药的爆炸产物抛撒运动及后燃特点,得到了温压炸药具有爆炸和后燃二个过程,爆炸场范围大,温度高,后燃持续时间长;高能炸药与温压炸药相比爆炸场范围小,温度低,几乎没有后燃过程;含铝炸药介于温压炸药和高能炸药之间。

The rapid dispersal process and phenomena of high explosive, aluminumed explosive and thermobaric explosive have been investigated experimentally with a high speed framing cameras. Compared with the characteristics of the dispersal process and afterburning of three kinds of explosive, we get the conclusions： for the thermobaric explosive, its explosion experiences （detonation and afterburning） bigger field, higher temperature and longer durative time of afterburning. As for high explosive, compared with thermobaric explosive, there is almost no afterburning process, its explosion is with smaller field, lower temperature and shorter durative time of afterburning. As for aluminumed explosive, its characteristics are between thermobaric explosive and aluminumed explosive.
