Ordnance Type Projectile Making, Including Finned Patents (Class 86/51)
  • Publication number: 20040031380
    Abstract: A method for producing a large-caliber, high-explosive projectile (1, 1′), and a projectile formed according the method, having a projectile casing (2, 2′) that surrounds a chamber (6, 6′) filled with an explosive charge (9, 9′), and that has a mouth (5, 5′) at its tip that can be sealed, and through which the explosive charge (9, 9′) is inserted into the chamber (6, 6′) of the high-explosive projectile (1, 1′). The explosive charge (9, 9′) is disposed in a plastic casing (8), comprised of an elastic material, inside the chamber of the high-explosive projectile (1, 1′). Additional tensioning means (11, 11′, 17, 17′) are provided to compensate for the varying volume of the explosive charge (9, 9′) relative to the projectile casing (2, 2′) if the temperature fluctuates dramatically and maintain the explosive charge (9, 9′) under a pre-stress, particularly when using a plastic bound explosive charge (9, 9′).

  • Patent number: 6619176
    Abstract: The embodiments of the present invention involve a thinned-skirt shaped-charge liner, a shaped-charge explosive incorporating the liner, and methods for making the liner. The focus of the most preferred embodiment of the present invention is the machining of the skirt portion of the liner to thin that portion to a thickness within about 25% of the thickness of the material around the center of the apex of the liner. The goal is to reduce debris and carrot size without sacrificing performance. In an alternative embodiment of the liner, at least some of the skirt portion of the liner is machined to a rough machine finish, but the mass of the material removed in the machining is insignificant to negligible. The liner of the present invention may be incorporated into a shaped-charge which includes a housing, a shaped-explosive, and the liner, preferably having an opening at the center of the apex of the liner.
