Abstract: An ammunition safety priming device using silicon micro-mechatronic systems technology, having at least two priming safeties intended to be deactivated by as many external independent physical events, includes at least one movable element, along a translation axis, for deactivating at least one of the priming safeties by action on said movable element of one of the physical events. Said movable element is produced in a material other than silicon. The device has applications including ammunition, rocket stage separation devices, and airbags.

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 projectile (3) to be launched by a marksman toward a target using a launch device, the projectile comprising a shaped-charge warhead (14) whose axis (38) coincides with that of the projectile, initiation of which is caused by an igniter (17). The projectile is characterized by a shaped charge which generates a core, and igniter (17) initiates the shaped charge along the trajectory and at a given distance from the launch device so that the marksman is protected from projectile explosions.

Abstract: A shaped charge, notably an explosively formed charge, incorporating an explosive charge arranged in a casing and onto which is placed a liner intended to be set into motion by the detonation of said explosive charge. The liner incorporates at least two plates, a rear plate which is in contact with said explosive charge and which is connected to said casing by attachment means and at least one front plate which is connected to said rear plate by bonding. The attachment means is positioned between a cylindrical peripheral surface of said rear plate and an inner cylindrical surface of said casing.

Abstract: The invention relates to a slug generating charge incorporating an explosive charge arranged in an envelope and a liner intended to be set into motion by the detonation of the explosive. The liner, whose thickness decreases between a central part and its periphery, is in contact with the envelope. A plate is placed between the explosive charge and the liner. The plate is of a diameter equal to the inner diameter of the envelope and is in contact with the liner at least at the latter's thinned peripheral part. The material of the plate is selected such that it reduces the velocity transmitted to the peripheral part of the liner by the explosive charge upon its ignition.
