Abstract: A shaped charge including an explosive load positioned in a casing, a liner applied on the load, and means ensuring the securing of the casing and the load bearing the liner. These securing means include a ring having a stop surface for the liner and at least two shims each covering an angular sector and moving radially by the action of a tightening means, to be pressed against an inner bearing surface of the casing. According to the invention, the tapped hole of the tightening screw(s) has its axis parallel to the axis of the casing and the shim is positioned axially relative to the ring by at least one radial pin authorizing sliding thereof.

Abstract: The object of the invention is an explosive ammunition (1) having a fragmenting structure comprising an explosive charge (3) configured in a splinter-generating shell (2). This ammunition is characterized by comprising a case (7) enclosing the shell (2) and containing means implementing a mechanical stress differential during ammunition ignition at the outer surface of the shell (2), where this differential enhances splinter generation and is distributed over a regular, 3D grid.

Abstract: A translational braking device for a projectile on its trajectory. The device has at least two air brakes made in the form of flaps that are moved in a plane perpendicular to the axis of the projectile to increase the aerodynamic drag of the projectile. Each flap has at least two closed grooves, extending essentially parallel to a direction that is perpendicular to the axis of the projectile, each groove cooperating with a rod that is fixed with respect to the projectile.
