Acceleration of projectile plate by sliding detonation wave: numerical modeling Keywords:projectile plate, detonation waves, high explosives Acceleration of projectile plate by a sliding detonation wave was modeled by numerical calculations. The flow of detonation products behind the detonation wave was analyzed to determine the pressure acting on the plate. Then the parameters of acceleration were derived from detailed analysis of plate motion. The suggested algorithm taking into account a real geometry of detonation front can be recommended for relatively simple determination of required plate configuration and acceleration parameters. | 3-16 |
