Abstract: front page image
(EN) An explosive charge (1) comprising an elongate casing (2) with elongate grooves (3,4) running along the casing, each groove locally reducing the thickness of the casing. The grooves are distributed in two or more groups around the circumference of the casing and the edge-to-edge spacing between each adjacent pair of grooves in a group is less than the edge-to-edge spacing between each pair of adjacent groups. Detonation causes the casing to break at a pair of grooves in one of the groups and form a fragment from material between the pair of grooves, the fragment cutting an obstacle (28).
(FR) L'invention concerne une charge explosive (1) comprenant une douille allongée (2) présentant sur sa longueur des rainures allongées (3, 4), chaque rainure réduisant localement l'épaisseur de la douille. Les rainures sont réparties en deux groupes ou plus autour de la circonférence de la douille, et l'espacement bord à bord entre chaque paire adjacente de rainures dans un groupe est inférieur à l'espacement bord à bord entre chaque paire de groupes adjacents. La détonation entraîne la rupture de la douille au niveau d'une paire de rainures dans l'un des groupes et forme un fragment de matière entre la paire de rainures, le fragment coupant un obstacle (28).
