A warhead configuration for forming a hole through a wall of a target, the warhead configuration comprising a charge of explosive material and a liner. The charge has an axis and a front surface. The front surface includes two annular front surface portions, an inner and an outer annular portion, circumscribing the axis. Each of the annular front surface portions is configured so as to exhibit a concave profile as viewed in a cross-section through the charge parallel to the axis. The liner includes a first liner disposed adjacent to the inner annular portion and a second liner disposed adjacent to the outer annular portion such that, when the charge is detonated, material from the first liner is formed into a first expanding explosively formed ring and material from the second liner is formed into a second explosively formed ring.
L'invention concerne une configuration de cône de charge qui permet de percer un trou dans la paroi d'une cible, cette configuration de cône de charge comprenant une charge de matière explosive et une assiette. La charge possède un axe et une surface frontale. Cette surface frontale comprend deux parties annulaires, une partie annulaire intérieure et une partie annulaire extérieure, qui circonscrivent l'axe. Chacune des parties annulaires de la surface frontale est conçue de manière qu'elle présente un profil concave, vu en coupe transversale à travers la charge parallèle à l'axe. L'assiette comprend une première assiette disposée à côté de la partie annulaire intérieure et une seconde assiette disposée à côté de la partie annulaire extérieure de sorte que, lorsque la charge détone, la matière comprise dans la première assiette forme un premier anneau expansif formé par explosion et la matière comprise dans la seconde assiette forme un second anneau expansif formé par explosion.
