Abstract

L'invention concerne une charge creuse à pénétration renforcée. Suivant l'invention, cela est obtenu en fixant à une enveloppe 10 pour l'explosif, à cône doublé 16, une structure rigide tronconique 18 dont l'axe coïncide avec celui du cône, dont la paroi interne est lisse dans le sens longitudinal. L'angle de conicité de la paroi tronconique va d'environ 8 degrés à 17 degrés pour une structure dont la longueur est d'environ 1,5 diamètres de la base du cône à environ 30 degrés lorsque cette longueur est de 0,9 à 0,4 diamètre. Cette paroi est agencée pour que le jet produit par l'explosion ne la touche pas. L'invention assure une pénétration accrue à la charge.
