摘要：

With the increase of the chemical energy of the modern solid propellant and the integration of the explosives and gunpowder technologies, the high energy solid propellant, containing a large number of explosive particles, presents a significant mechanical sensitivity and shock sensitivity, which would easily induce the sympathetic detonation. In order to investigate the features of the sympathetic detonation of solid propellant, this paper has researched the sympathetic detonation process of the high energy solid propellant by experiments and numerical simulations. The study found that under the blast impact of the solid propellant, the shells are partially damaged into pieces. The fragments impacted on the solid propellant acceptor with high speed, which caused uneven distribution of the thermal energy. The thermal energy concentrated on the sharp corners or projecting parts of fragments, which led to the temperature excursion, reaching the critical point. Next, the sympathetic detonation of the solid propellant finally occurred. ©, 2014, Editorial Board of Journal of HEU. All right reserved.
