Abstract

To investigate the detonation characteristics and the detonation wave profiles of the melt-cast aluminized explosive RBOL-2 (DNAN/HMX/aluminum/other additives), the particle velocity of the interface between the explosive and the Lithium-Fluoride (LiF) window and the free-surface velocity of the copper plate accelerated are measured by using the DISAR interferometer system. It is found that, for RBOL-2 explosive, the reaction zone length is 202 ± 2.5 ns/1.073 ± 0.013 mm, the particle velocity and the pressure at the Von Neumann spike are 2364 ± 3 m/s and 41.80 ± 0.07 GPa, respectively, and the particle velocity and the pressure at the Chapman-Jouguet point are 1564 ± 3 m/s and 25.42 ± 0.05 GPa, respectively. Moreover, the parameters of the Jones-Wilkins-Lee (JWL) equation of state of the RBOL-2 explosive are also determined by the genetic optimization algorithm and the measured free surface velocity of the copper plate.
