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 粉的加入显著提高了比气泡能,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。

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 re-sults show that its specific shock wave energy of sample is 1. 38 times of TNT and is equivalent to RS211; its specific bub-ble 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 im-proved 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.
