Patent number: 8640623Abstract: A multiple-purpose projectile assembly includes an anti-personnel projectile, an armor-penetrating projectile, a propellant, a base bleed gas, and a primer. The anti-personnel projectile includes a cavity having a scored surface and is made out of a soft metal. The armor-penetrating projectile is made from a hard metal and is housed partially within the cavity of the anti-personnel projectile prior to firing from a weapon. The propellant and the primer are both housed within the cavity. The firing of the projectile assembly causes the armor-penetrating projectile to drive into the primer, thereby detonating the primer, causing the detonation of the propellant, thereby increasing the pressure of the cavity and causing the two projectiles to separate after the projectile assembly leaves the bore of the weapon. The burning of the propellant releases a base bleed gas that reduces the drag experienced by the anti-personnel projectile.Type: GrantFiled: November 17, 2011Date of Patent: February 4, 2014Inventor: Donald B.

Publication number: 20120266772Abstract: A projectile assembly 10 includes an individual projectile 20 and a composite projectile 30. The individual projectile 20 has a communicating portion 22. The composite projectile 30 includes at least one flechette 32. Prior to the projection of the projectile assembly 10, the composite projectile 30 is located adjacent to the communicating portion 22 of the individual projectile 20. The individual projectile 20 and the composite projectile 30 are structured and disposed for separating from one another after the initial projection of the projectile assembly 10.Type: ApplicationFiled: November 17, 2011Publication date: October 25, 2012Inventor: Donald B.

Patent number: 8267015Abstract: A projectile has a leading part, a trailing part and a cylindrical interface that interconnects the leading and trailing parts. A non-round aperture having a predetermined longitudinal extent is formed in the trailing end of the leading part and a non-round peg having a predetermined longitudinal extent substantially equal to the predetermined longitudinal extent of the non-round aperture is formed in the leading end of the trailing part. The non-round peg is slideably inserted within the non-round aperture when the leading end of the cylindrical interface abuts the trailing end of the leading part and the trailing end of the cylindrical interface abuts the leading end of the trailing part so that the leading and trailing parts of the projectile rotate conjointly with one another when the projectile is rotating about its axis of rotation.Type: GrantFiled: May 21, 2010Date of Patent: September 18, 2012Assignee: Liberty Ammunition, Inc.Inventor: PJ Marx

Patent number: 8250987Abstract: A Kinetic Energy penetrator round is shown effective in neutralizing incoming air borne threat munitions such as rockets, artillery, or mortars for instance, without posing a threat in urban environments to harm bystanders on the ground. There are also no hazards or expense with this round of cleaning up unexploded ordnance, which might have occurred with other types of rounds due to unreliability of self destruct mechanisms. Shown herein is a kinetic energy penetrator for air defense that merely self destructs beyond its operational range into fragments that are not lethal to personnel on ground; no pyrotechnic or energetic materials means are used to activate this self destruct process. A full bore projectile structure is shown that is composed of plural axi-symmetric circular disks stacked on each other and tied by a shape memory metal wire of Nitinol. While operational as a joined group, the disks are a formidable round to kill an incoming air target.Type: GrantFiled: July 14, 2009Date of Patent: August 28, 2012Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Andrew Morley, Mohan J. Palathingal, Leon Manole, Ernest L. Logsdon, Jr.

Publication number: 20120199035Abstract: A segmenting slug has a body having a generally dome-shaped forward portion, a generally cylindrical rearward portion, and an opening in the rear of the body forming an interior chamber. There are a plurality of generally radially extending notches in the dome-shaped forward portion of the slug, and a longitudinally extending groove in the wall of the interior chamber substantially aligned with each notch.Type: ApplicationFiled: February 6, 2012Publication date: August 9, 2012Inventor: Ben N.

Patent number: 8225718Abstract: A lead-free, frangible bullet is provided. The lead-free, frangible bullet is manufactured without sintering or external heating of the bullet. The bullet is prepared by blending a lead-free copper powder mixture and cold compacting the powder in a die to form a bullet. The copper powder can be atomized copper powder, electrolytic copper powder, or a combination of atomized and electrolytic copper powder. The atomized copper powder can be water atomized, air atomized, and combination of water and air atomized. Preferably, the frangible bullet has a fragmentation less than 5 grains.Type: GrantFiled: October 8, 2009Date of Patent: July 24, 2012Assignee: United States Metal Powders IncorporatedInventors: Jessu Joys, Barry Anshutz, K. Clive Ramsey

Publication number: 20120180686Abstract: A frangible projectile, and weapon cartridge containing same, is provided, in which the frangible projectile is comprised of a hollow outer body composed of, for example, a plastic or polymeric material, configured to provide a payload material. Preferably, the hollow outer body has an interior surface having a divider formed or disposed therein, for controlling the movement of the payload material after firing. The hollow outer body of the frangible projectile, upon impact, rapidly fragments upon impact into relatively harmless pieces, and releases/mixes the payload material. However, the payload material may be chosen to provide sufficient mass, and accordingly sufficient kinetic energy, to provide desired target effects, such as powder metals. Alternatively, payload materials, such as reactive chemical components, marking agents, chemiluminescent compositions, incapacitants, multi component reactive compositions, etc., preferably contained within one or more payload containers, are provided.Type: ApplicationFiled: January 21, 2011Publication date: July 19, 2012Inventors: Kenneth R. Jones, Frank J. Dindl
