含铝炸药水下爆炸性能的实验研究

对RS211、HL-1、HL-2这3种含铝炸药和TNT炸药进行了水下爆炸实验,测量了4种炸药水下爆炸冲击波压力剖面和气泡脉动周期,获得了4种炸药水下爆炸冲击波的峰值超压、冲量、能量和气泡能。实验结果表明,在所研究的范围内,与TNT炸药相比,含铝炸药的冲击波能量有明显增加,约为TNT炸药的1.20～1.35倍,气泡能有显著增加,约为TNT炸药的1.50～2.30倍,表明在炸药中加入铝粉对于提高炸药水中爆炸威力是有益的。

Experimental Study on Underwater Explosion Performance of Aluminized Explosive

The blast shock wave pressure and the bubble pulse period of RS211, HL-1, HL-2 and TNT explosives were measured, and then the peak pressure, shock wave impulse, shock wave energy and bubble energy were obtained. The experimental results showed that in the studied range, the shock wave energies and the bubble energies of the three aluminized explosives were about 1.20~1.35 and 1.50~2.30 times more than TNT explosive, respectively. The analysis results indicated that the aluminum powder added to explosives can enhance underwater explosion power of the explosives.
