Patent number: 11359901Abstract: A munition includes a warhead having a warhead axis and axially opposed first and second warhead ends. The warhead includes: a tubular shock attenuation barrier including an axially extending passage extending from a first barrier end proximate the first warhead end to a second barrier end proximate the second warhead end; an explosive core charge disposed in the passage; an explosive main charge surrounding the shock attenuation barrier; projectiles surrounding the main charge; a core charge detonator; and a main charge detonator. The warhead is configured to be activated in each of a first projection mode and an alternative second projection mode. When the warhead is activated in the first projection mode, the main charge detonator detonates the main charge to thereby forcibly project the projectiles from the warhead with a first set of projection velocities and velocity profile.Type: GrantFiled: March 11, 2021Date of Patent: June 14, 2022Assignee: Corvid Technologies LLCInventors: David Thomas Stowe, Andrew John Auvil

Publication number: 20080141891Abstract: A method for reducing the amount of ammunition types to be used against a wide set of targets. At least two explosive charges are made use of in cooperation. Each of the explosive charges has changeable characteristics and is arranged to mutually cooperate in different ways depending on the particular changeable characteristics given to the explosive charges in a specific case and the type of target to be combated. An ammunition device admitting a reduction of the amount of ammunition types to be used. At least two cooperating explosive charges are arranged in a row along the direction of movement of the ammunition device when activated. Each of the explosive charges is switchable between at least two operating conditions having different operating characteristics.Type: ApplicationFiled: March 8, 2007Publication date: June 19, 2008Applicant: SAAB ABInventors: Christer Regebro, Jyrki Helander

Patent number: 7284490Abstract: Rod warhead systems and associated methods are disclosed. In one embodiment, a projectile having an arrangement of rods is propelled along a trajectory toward an object. The arrangement of rods is radially expanded from a first position to a second position prior to the projectile impacting the object. The arrangement of rods impacts the object to breach at least a portion of the object. In a further embodiment, the arrangement of rods is expanded from the first position to the second position using a nonexplosive means. In another embodiment, the projectile includes a follow-up explosive device that applies an explosive force proximate to the object after the arrangement of rods impacts the object.Type: GrantFiled: May 28, 2004Date of Patent: October 23, 2007Assignee: Armtec Defense Products Co.Inventor: Enrico R. Mutascio

Patent number: 6681679Abstract: The invention relates to a wall (2)-protection device (1), notably for a vehicle wall, against attack by a projectile. This device comprises at least one explosive charge (3) able to project at least one metallic block (7) in the direction of the projectile. The device is characterized in that the block or blocks (7) are in the shape of elongated bars, that is which have a maximal length greater than or equal to 10 times their smallest crosswise dimension, the explosive charge (3) being position opposite a longitudinal surface of the bar (7).Type: GrantFiled: September 5, 2001Date of Patent: January 27, 2004Assignee: Giat IndustriesInventors: Michel Vives, Alain Kerdraon, Jean-Paul Duparc

Patent number: 6279482Abstract: There is provided a countermeasure defense system against hostile missiles by employing non-explosive intercepting (“NEI”) elements 14 deployed by the spin stabilized rocket 10. The NEI are carried in a payload section 17 and contained by a sleeve assembly 16 which is removed by a drive mechanism 20 or a pyrotechnic device 152 after a countdown time delay programmed into the trigger release assembly 46 as controlled by the control unit 150. The drive assembly includes a drive rod 26 that is releasably held by a release assembly 46 a compressed coiled spring unit 30 drives the sleeve assembly 16 forward exposing the payload section 17 to the centrifugal force of the spin stabilized rocket propelling the NEI elements out from the rocket at constant angular velocity creating an interceptor cloud of elements.Type: GrantFiled: October 31, 1997Date of Patent: August 28, 2001Assignee: TRW Inc.Inventors: David P. Smith, Jane M. Lin

Patent number: 5408932Abstract: An elongated rod made of a shape memory alloy composition having selected eudoelastic properties, is deformed into a dimensionally compact coil for packaged storage under stress maintained by physical constraint. Upon selective removal of the constraint allowing shape recovery, a substantial increase in axial length of the rod occurs in order to improve its performance in various installations, including long rod penetrating projectiles.Type: GrantFiled: September 7, 1994Date of Patent: April 25, 1995Assignee: The United States of America as represented by the Secretary of the NavyInventors: Philip W. Hesse, David Goldstein

Patent number: 4459915Abstract: A solid fuel rocket in which the rocket casing acts as a warhead. Solid propellant rocket motors require relatively heavy cases to contain the 1000-2000 psi combustion pressure needed for efficient performance. This casing can be used as a fragmentation warhead by forming longitudinal grooves in the elongated rocket casing, causing the casing to fracture along the grooves and allowing the pressure within the casing to disperse the fragments. The resulting strip-like fragments are particularly useful against "soft" equipment targets, such as anti-vehicle and anti-radar applications. Several different methods for rupturing the case along spaced, parallel longitudinal lines are disclosed. This system eliminates the need for a separate warhead including case and explosive at the cost of a slight increase in propellant case thickness and weight.Type: GrantFiled: October 18, 1982Date of Patent: July 17, 1984Assignee: General Dynamics Corporation/Convair Div.Inventor: Robert A. Lynch

Patent number: 4296180Abstract: A process for producing a formed member, and a formed member which includes spherical fragments embedded in a metallic matrix is effected through round cold forging. The spheres are arranged in the interspace between a basic support member, which may be a thinwalled inner casing, and an outer casing. Forging of the outer casing causes the material of the support member and the outer casing to be pressed into the spaces between the spheres, densifies the support member and the outer casing, and prestresses the outer casing and spheres, thus allowing the inner casing to be extremely thinwalled. The prestressing of the spheres and outer casing, together with the inner casing imparts a high degree of energy to the casing fragments and to the spheres, affords economies in manufacture and a substantial increase in fragmenting energy at detonation of the formed member.Type: GrantFiled: November 19, 1979Date of Patent: October 20, 1981Assignee: Diehl GmbH & Co.Inventors: Siegfried Rhau, Adolf Weber

Patent number: H1367Abstract: A wire assault weapon warhead preferably for breaching barbed-wire barrics in a battlefield at standoff distances, has a cylindrical shaped projectile having a domed nose cone and a rear bulkhead sized so as to allow the warhead to be fired from a Shoulder-Fired Multi-Purpose Assault Weapon or a similar weapon. The warhead includes a fragmentation tube that fragments upon the detonation of an explosive charge and the fragments expelled into the wire of the barricade sever the wire and breach the barricade.Type: GrantFiled: February 7, 1991Date of Patent: November 1, 1994Assignee: The United States of America as represented by the Secretary of the NavyInventors: Louie A.
