Abstract
A high explosive assembly and a method are disclosed for projecting a long od at high velocity with enhanced penetrating energy. The high explosive assembly has an elongated core of a first high explosive having a first Chapman-Jouguet detonation velocity, an elongated liner positioned substantially along the longitudinal axis of the core, and an elongated jacket of a second high explosive encasing the core and having a second Chapman-Jouguet detonation velocity greater than the core Chapman-Jouguet detonation velocity. The jacket high explosive, upon detonation, continuously initiates detonation of the core high explosive by an imposed oblique detonation front which converges toward the center of the detonating core with time, until a trailing mach stem emerges therefrom as detonation progresses. The mach stem grows with time as the detonation continues until a steady state mach stem disk results, and detonation proceeds further as a highly overdriven detonation of the core to expel the liner as a long rod at high velocity.
