Patent number: 7520224Abstract: 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.Type: GrantFiled: August 18, 2006Date of Patent: April 21, 2009Inventor: John D. Taylor

Publication number: 20080257139Abstract: 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.Type: ApplicationFiled: March 28, 2008Publication date: October 23, 2008Inventor: Leslie Mervyn Harrison

Patent number: 7437996Abstract: A kinetic energy penetrator includes a plurality of penetrator segments, a penetrator segment sleeve for storing the plurality of penetrator segments, and means for moving the plurality of penetrator segments from the penetrator segment sleeve to locations substantially aligned along an axis of attack. A method includes storing a plurality of penetrator segments away from an axis of attack and moving the plurality of penetrator segments to locations substantially aligned along the axis of attack. A vehicle includes a body and a kinetic energy penetrator disposed in a forward portion of the vehicle. The kinetic energy penetrator includes a plurality of penetrator segments, a penetrator segment sleeve for storing the plurality of penetrator segments, and means for moving the plurality of penetrator segments from the penetrator segment sleeve to locations substantially aligned along an axis of attack.Type: GrantFiled: September 21, 2005Date of Patent: October 21, 2008Assignee: Lockheed Martin CorporationInventors: Mark A. Turner, William R. Greisser

Publication number: 20080156220Abstract: 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.Type: ApplicationFiled: March 11, 2005Publication date: July 3, 2008Inventor: Catherine Tanguy

Patent number: 7383760Abstract: 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.Type: GrantFiled: August 17, 2005Date of Patent: June 10, 2008Assignee: Penn United Technologies, Inc.Inventors: Charles Morrison Phillips, William Harry Rodgers, Michael Wayne Kelley, Robert Anthony Gagliardi, Regis A.

Patent number: 7114449Abstract: 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?).Type: GrantFiled: September 30, 2004Date of Patent: October 3, 2006Assignee: Rheinmetall W & M GmbHInventor: Ernst-Wilhelm Altenau
