Abstract

Le secteur technique de l'invention est celui des charges explosives génératrices de noyau. La charge selon l'invention comporte une plaque (6) disposée entre le chargement explosif (3) et le revêtement (5), cette plaque a un diamètre égal au diamètre interne de l'enveloppe (2) de la charge (1). Le matériau de la plaque (6) est choisi tel qu'il ait une densité inférieure ou égale à celle du matériau du revêtement (5) et un module de compressibilité volumique supérieur ou égal à 100 GPa, l'épaisseur de la plaque étant supérieure ou égale à celle du revêtement en tout point d'une zone centrale entourant l'axe de la charge, de façon à assurer lors de l'initiation de la charge une déformation centripète de la plaque moindre que celle du revêtement.
