摘要
为了有效提高炸药的爆轰能量,基于硼粉具有约2倍于铝粉的体积热值和质量热值的特点,进行了含硼金属化炸药的水下和空中爆炸能量输出特性测试,研究了硼粉的加入对含铝金属化炸药能量大小及输出结构的影响。试验结果表明,硼粉在爆轰过程中的能量释放主要用来提高水下气泡能和空爆火球的持续时间。
In order to effectively improve the detonation energy of explosives, based on the characteristics that boron has twice higher calorific value of the volume and the mass than that of aluminum, the air explosive energy output characteristics and under-water energy output characteristics of boron-containing explosive were tested, the effect of adding boron on the explosive energy magnitude and make-up was investigated. The results showed that high energy output of boron can increase the a/r-explosion fireball duration and under-water bubble energy.
