【 摘 要 】

To investigate the influence of the booster size on the total energy of DNAN-based insensitive melt-cast explosive RBUL-1, six groups of underwater explosion experiments with varied booster sizes were carried out to measure the total energy of RBUL-1 explosive. Experimental results show that the booster size especially the booster diameter has a great influence on the total energy of RBUL-1 explosive. An expression was proposed and calibrated to illustrate the relationship between the total energy of RBUL-1 explosive and the booster size. Besides, the booster size used in the underwater explosion experiments was optimized to achieve higher total energy results. The present investigation has practical significance for the design of the booster sequence and warhead.
