    Abstract: An armor penetrating round includes an elongated core portion (e.g., a hollow tool steel core) defining a front end, an aft end, and a central cavity which extends from the aft end toward the front end. The central cavity has (i) an aft cross-sectional diameter adjacent the aft end and (ii) a front cross-sectional diameter adjacent the front end, the aft cross-sectional diameter being larger than the front cross-sectional diameter. The armor penetrating round further includes a slug portion (e.g., a pre-compacted pellet of powdered metal) which is disposed within the central cavity adjacent the aft end, and an outer jacket (e.g., a copper jacket) which extends around the elongated core portion to operate as an interface between the armor penetrating round and a gun barrel when the armor penetrating round is fired through the gun barrel.

  • Publication number: 20100229751
    Abstract: The present inventions provide methods of manufacturing methods for case metallic materials for munitions that have high enthalpic energy release and controlled fragmentation and breakup enabling fragment speeds up to twice what is otherwise possible in explosively driven metal systems, and munitions made by such methods. Embodiments of the invention involve the thixotropic processing of energetic materials such as aluminum together with high density materials such as tantalum or tungsten to achieve material microstructures with a bulk density equivalent to steel, but with the energy release potential of materials such as finely dispersed aluminum powders.

  • Patent number: 7665402
    Abstract: A method of manufacturing ammunition 10 for firing from the barrel of a weapon comprises forming a mould 32 having an interior surface, placing a core 42 in the mould 32 to produce a casting void 43 and pouring a liquefied solidifiable material into the casting void 43. Upon solidification of the material, the core 42 is removed to produce a projectile body 12 having a closed end and an opposite end. The removal of the core 42 also creates the cavity 18 in the projectile body 12 that opens onto the opposite end. The projectile body 12 is removed from the mould 32 and a quantity of propellant 22 is deposited into the cavity 18 through the opposite end. A seal 26 which incorporates a primer is pressed into the opposite end. Circumferential flanges 30a and 30b are integrally moulded with the projectile body 12.

  • Patent number: 7520224
    Abstract: A firearm projectile includes a precision-machined outer component having a generally cylindrical body, a tip at the forward end of the body, a base at the rear end of the body, and a precision-machined cavity machined into the outer component. A precision-machined inner component is pressed into the cavity. The outer component includes a homogenous material that is softer than firearm barrel steel. The inner component includes a material having a higher density than the outer component and a higher density than an armor plate, such as solid tungsten, tungsten carbide and potential some Nanotechnology materials such as NanoSteel™. A cap may be attached to the outer component to seal the inner component inside the cavity. The cavity can be machined from the front or rear end of the outer component. The cap fits into the rear of the projectile or may be a bullet tip. The cavity and the inner component may be cylindrical or tapered.

  • Patent number: 7383760
    Abstract: A method of making flechettes employing the use of a progressive die which forms (a) wire that results in the flechette, and (b) strip material that results in a carrier for the finished flechettes. The carrier, which is a bandolier apparatus, is used for progressing the flechette through the progressive die at various forming stations. After forming of the flechette in the die is complete, the final flechette can be severed from the bandolier, or the flechette can remain intact with the bandolier for post-forming operations, such as coating/finishing. The bandolier is thus a novel approach to transporting the flechettes in both forming and post-forming processing.

  • Patent number: 7114449
    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?).
