摘要
为了解硼含量对燃料空气炸药爆炸性能的影响规律,将硼粉和铝粉作为高能金属燃料混合添加到燃料空气炸药(配方体系为铝/硼/环氧丙烷/石油醚/硝酸异丙酯)中,采用静爆试验法,对含硼量不同的燃料空气炸药爆炸超压、冲量及热效应进行研究。研究结果表明:随着燃料空气炸药中硼含量的增加,炸药的冲击波超压、超压冲量和热效应均先增大、后减小;当硼含量为12.5%时,炸药的地面冲击波超压冲量为112.51 KPa·s,比含铝样品高6.16%,空中冲击波超压冲量为63.42 KPa·s,比含铝样品高5.16%;当硼含量为12.5%时,最高爆炸温度是1 650℃,比含铝样品提高20℃,最大热辐射量为68.266 k J/m^2,比含铝样品的最大热辐射量提高约7.14%.在含铝燃料空气炸药中添加少量硼粉,可以提高炸药的整体能量水平。
In order to know the influence of boron content on explosion performance of fuel-air explosive, the mixture of boron and aluminum is added to fuel-air explosive with formulation of B/Al/PO/petroleum ether/IPN, and a static explosion is performed to study the influence of boron content in the mixture on the explosion overpressure, impulse and heating effect. The test results indicate that the explosion overpressure, impulse and heating effect increase firstly and then decrease with the increase in boron content in fuel air explosive （FAE）. When the mass fraction of boron is 12.5% , the ground impulse of the explosive reaches to 112.51 KPa＇s, which is 6.16% higher than that of the aluminized FAE. When the mass fraction of boron is 12.5% , the explosion temperature reaches to 1 250 ℃ , which is 20 ℃ higher than that of the aluminized FAE. When the mass fraction of boron is 12.5% , the biggest thermal radiation reaches to 68. 266 kJ/m^2, which is 7.14% higher than that of the aluminized FAE. Adding some boron powders to Al-B mixture can improve the underwater detonation energy of the aluminized FAE.
