  • Publication number: 20050230016
    Abstract: An incendiary composition (14) for a fin-stabilized kinetic energy projectile (1) which can be arranged in the tail region of the projectile (1) and, upon impact with a target (13), penetrates the target (13) as a separate unit behind the penetrator (2) of the kinetic energy projectile (1). To reach the objective of a high destructive effect caused by the incendiary composition (14) within a target (13), despite a small volume and a low mass, and to ensure that the incendiary composition is ignited securely by the shock waves generated upon impact, according to the invention, a titanium sponge is used as the incendiary composition (14), with an epoxide resin or a polyester resin used as a binder.

  • Publication number: 20040084330
    Abstract: A packing case (1) for a large-caliber cartridge (2), having a thin-walled cartridge case (3) and a projectile (4), which protrudes at least partially out of the front of the cartridge casing (3), and has at its outer circumference an annular stop groove (5), with the packing case (1) including an outer case (6) and an inner case (7) that comprises at least two partial cases disposed one behind the other. To enable the cartridge to be easily secured in the packing case and subsequently removed, at least two spring-loaded stop elements (19) that can pivot toward the projectile (4) and have guide elements (21) are provided. The stop elements extend with a form-fit into the stop groove (5) of the projectile (4) and are supported at the rear against a partial case (11) of the inner case (7).

  • Patent number: 5042389
    Abstract: A large-caliber carrier projectile for transporting a payload, with the projectile including an ejection charge and an ejector plate for ejecting the payload from the carrier projectile over a target area. To overcome the problem of the ejector plate colliding with individual bomblets of the payload, and thus causing considerable interference with proper functioning or premature detonations in the air, the ejector plate is an eccentric center of gravity. Alternatively, the ejector plate may be segmented and composed of at least two separable parts which are separated by the action of centrifugal force after ejection from the carrier projectile.

  • Patent number: 5016533
    Abstract: A bomblet projectile includes a projectile body, a fuse housing on the body at the rear end thereof; and an unwindable stabilization band for stabilizing the position of the projectile while dropping. The band forms, in the deployed state, a loop having leg portions terminating in fastening regions secured to the fuse housing and a dome portion flanked by the leg portions. The band has a length and different widths along the length. The band has its greatest width in the dome portion and its smallest width in the leg portions, externally of the fastening regions.
