Several aluminum-based explosives are prepared and their underwater explosion performances, including the specific bubble energy and specific shock wave energy, are measured in underwater explosion experiments. The formulation characteristics of the explosives involve the aluminum/oxygen (Al/O) ratio, aluminum particle size, and the total content of all solid components, including ammonium perchlorate (AP), aluminum (Al), and cyclotrimethylenetrinitramine (RDX). The results indicate that the Al/O ratio of the explosives produces a great effect on the specific shock wave energy and specific bubble energy of the explosives. The total specific energy of the explosive reaches the maximum value at Al/O = 0.44. It is notable that an increase in the total solid content (AP, Al, and RDX) in the explosive formulation can effectively increase the specific total energy of the explosives. When the total solid content is increased by 2% (by weight) in the explosive formulation, the total energy of the explosive can be increased by about 0.1 times the TNT equivalent. Moreover, the particle size of the aluminum powder can also significantly affect the energy of the explosives. The smaller particle size of the aluminum powder is beneficial to the energy release of aluminum and can increase the total explosion energy.

铝粒度、固含量和铝氧比对铝基炸药水下爆炸性能的影响

制备了几种铝基炸药，并在水下爆炸实验中测量了它们的水下爆炸性能，包括比气泡能量和比冲击波能量。炸药的配方特征涉及铝/氧（Al/O）比、铝粒径和所有固体成分的总含量，包括高氯酸铵（AP）、铝（Al）和环三亚甲基三硝胺（RDX）。结果表明，炸药的Al/O比对炸药的比冲击波能和比气泡能有很大影响。炸药的总比能在Al/O=0.44时达到最大值。值得注意的是，总固体含量（AP、Al、和RDX)在炸药配方中可以有效提高炸药的比总能量。当炸药配方中总固体含量增加2%（按重量计）时，炸药的总能量可增加约0.1倍TNT当量。此外，铝粉的粒度也会显着影响炸药的能量。铝粉粒径越小，有利于铝的能量释放，增加总爆炸能。铝粉的粒度也会显着影响炸药的能量。铝粉粒径越小，有利于铝的能量释放，增加总爆炸能。铝粉的粒度也会显着影响炸药的能量。铝粉粒径越小，有利于铝的能量释放，增加总爆炸能。
