Placing Bursting Charge In Projectile Patents (Class 86/20.14)
  • Patent number: 8739671
    Abstract: A method is provided for producing a large-calibre explosive projectile having a projectile casing with an ogival front part, which surrounds an internal area filled with a plastic-bonded explosive charge and, at a nose end, has a mouth closed by a nose fuze, wherein an elastic liner is arranged between the explosive charge and the inner wall of the projectile casing. The projectile casing is produced in two parts, such that, in the direction of the longitudinal axis of the projectile casing, a tail-end projectile casing section and an annular front projectile casing section, which contains the mouth, can be connected to one another in the area of the ogival front part, via a screw connection. The liner is introduced into the tail-end projectile casing section and the explosive charge is introduced into the liner before the two projectile casing sections are connected to one another.

  • Publication number: 20080156220
    Abstract: The invention relates to a fragmentable grenade (1) including an explosive charge (2) and a layer (4) of projectiles (5), which are elastically deformable and joined by bridges of material (6) produced by moulding together with the projectiles (5). The layer (4) surrounds the charge (2) and is designed for enabling the projectiles (5) to separate and disperse when the charge (2) explodes.

  • Patent number: 6874425
    Abstract: A projectile carrying sub-munitions which may exhibit orientational sensitivity utilizes a resilient member to prevent individual grenades from rotating out of the desired orientation. As a skilled artisan would readily understand, the sub-munitions is one type of rotationally sensitive device. Other types of rotationally sensitive devices include but are not limited to grenades, grenade fuses and sub-munition fuses. In the described embodiments, artillery shells carrying grenades packed in circular arrays around a central longitudinal axis may exhibit orientational sensitivity with some types of slide fuses, such that an optimal orientation is that the slide fuse faces outwardly along a radial line from the longitudinal axis.
