摘要:
为了研究DNTF(3,4-二硝基呋咱基氧化呋咱)/AP/Al体系炸药的能量特性,选取了质量比为DNTF/AP/Al(35/35/30)的试样进行了水下爆炸能量测定和爆热测试,并将试验结果与TNT和RS211进行了对比。结果表明:试样的比冲击波能是TNT的1.38倍,与RS211相当;比气泡能分别为TNT和RS211的4.56倍和2.91倍;总能量为TNT和RS211的3.56倍和2.26倍。经计算发现试样的能量利用率高达98%。为了研究造成该配方试样高气泡特性和高能量利用率的原因,通过分析对比试样、DNTF和DNTF/Al(70/30)体系的水下爆炸试验结果发现,Al粉的加入显着提高了比气泡能,降低了热损失能;Al粉和AP的联用进一步提高了比气泡能和能量利用率,同时也提高了比冲击波能。
Abstract:
A DNTF/AP/AL explosive sample with mass ratio of 35/35/30 was selected to measure the underwater explosion energy and explosion heat in comparison with TNT and RS211 for the study of its energy characteristics. The results show that its specific shock wave energy of sample is 1.38 times of TNT and is equivalent to RS211; its specific bubble energy can be 4.56 and 2.91 times of TNT and RS211, respectively; and its total energy is 3.56 and 2.26 times of TNT and RS211, respectively. The calculation indicates that the sample has an energy efficiency up to 98%. Underwater explosion experimental results were analyzed for DNTF and DNTF/Al (70/30) system to determine the factors responsible for the high bubble characteristic and high energy efficiency. It was found that the addition of Al powder significantly improved the specific bubble energy and reduced the heat losses. The combined usage of Al powder and AP can result in a further increase in specific bubble energy and energy efficiency, and higher specific shock wave energy.
