N2 - A series of experiments is performed to compare underwater shock wave attenuation of a new insensitive and aluminized high explosive RS with TNT, JH14, and PBXN- 111 explosives. A new model with a uniform expression is proposed to characterize the pressure-time histories of the explosives. Numerical results show that the new model is applicable for both aluminized explosives and ideal explosives. The correlation coefficients for fitted curves are verified by thousands of test data for different explosives, and the accuracy is above 0.99. The energy of the underwater shock wave generated by PBXN-111 and TNT characterized by the new model agrees well with available experimental results. In addition, the shock energy of the new insensitive and aluminized high explosive RS is higher than that of PBXN-11 by 13.4%. The general performance of underwater shock wave attenuation of the insensitive and aluminized high explosive RS is found to be better than that of TNT, JH14, and PBXN-111 explosives.
