摘要
理论计算了DNTF基含硼和含铝炸药的爆炸性能参数,通过水下能量及爆热测试研究了它们的能量特性。结果表明,含硼质量分数15%的DNTF基炸药水下能量可达到2.1倍TNT当量,并出现最大值。含铝质量分数10%-50%的DNTF基炸药的水下能量随铝含量的增加呈上升趋势,其最大值可达到2.67倍TNT当量。当铅或硼的质量分数低于18%时,含硼DNTF炸药的能量高于含铝炸药。硼铝联用,也可获得较好的能量特性。
The explosion performance of DNTF based boron-contained and aluminum-contained explosive is calculated theoretically, and their energy characteristics are studied through determining the underwater energy and explosion heat. The results show that when the mass fraction of boron in the DNTF based boron-contained explosive is 15%, the underwater energy of this explosive arrive to 2.1 TNT equivalent,revealing the maximum peak in the content of boron vs. TNT equivalent curve. With increasing the mass fraction of aluminum from 10% to 50%, the underwater energy of DNTF based aluminum-contained explosive raises. The maximum energy corresponding to the mass fraction of aluminum of 50% is 2.67 TNT-equivalent. When the content of comburant is less than 18%, the energy of boron-contained explosive is better than that of aluminum-contained explosive. If boron and aluminum are used together, better energy characteristics can be obtained.
