Armour-piercing hollow charge

Abstract

Abstract This hollow charge intended for piercing "clear" holes of great depth has rotational symmetry about an axis X and comprises an explosive charge (10) in which is made an open cavity (11) having a metal covering (12), and a priming device consisting of a priming charge (16) and ignition means (17); the profile of the cavity (11) is shaped so as to impart to the core and to the metal jet occurring as a result of the implosion of the metal covering translational speeds which are different and oppositely directed. The thickness (e) of the metal covering (12) increases progressively from the top of the cavity to the base, and the priming charge (16) comprises a shaper (14) including a cylindrical metal element (20) to ensure an annular ignition of the detonation wave. This hollow charge is used in the military and civil sectors.
