Patent number: 9658044Abstract: There is a firing and arming system, such as an activation system, of a munition for quickly and accurately activating a warhead or a propulsion system of the activation system. An initiator interface of the activation system activates the warhead or propulsion system. At least one power source is included in the activation system to provide the initial power for activation of the initiator interface and subsequent activating of the respective warhead or propulsion system. Logic elements are communicatively disposed between the at least one power source and a flux compression generator circuit to control activation of the generator. The flux compression generator circuit is at least partially detonated to transform current received from the at least one power source into sufficient current for activating the initiator interface.Type: GrantFiled: March 3, 2015Date of Patent: May 23, 2017Assignee: Raytheon CompanyInventors: Tim B.

Publication number: 20160025467Abstract: A directed munition has a non-fragmentation casing, and an explosive within the casing that is configured to propel fragments out an opening of the casing when the explosive is detonated. The casing may be made of a material that does not produce lethal or injurious fragments when the explosive is detonated. The explosive may include an insensitive explosive portion that creates the shape of an explosive front, and a secondary explosive containing a more energetic explosive, which is closer to the fragments than the insensitive explosive portion. There may be more of the insensitive explosive than the relatively energetic explosive. The munition may have a ring that is operatively coupled to the fragments, to aid in directing the fragments out of the casing opening in a desired direction. The ring may be made of a material that does not produce injurious fragments when the explosive is detonated.Type: ApplicationFiled: July 22, 2014Publication date: January 28, 2016Inventors: Brian S.

Patent number: 8173946Abstract: A method of defeating an incoming missile, such as a rocket propelled grenade, includes soft launching an interceptor missile, and then using pitch over motors of the interceptor missile to alter course of the missile to a desired interception direction. By launching at a relatively slow speed, such as a speed less than or equal to 40 m/sec (130 ft/sec), the interceptor missile may reach the desired interception direction within 250 milliseconds of launch. The interceptor missile may be able to cover substantially all interception directions over a hemisphere or greater extent around a launch location. For example, the interceptor missile may be launched vertically from a ground vehicle, and be capable of altering course to any above-ground trajectory within 250 milliseconds.Type: GrantFiled: August 26, 2008Date of Patent: May 8, 2012Assignee: Raytheon CompanyInventors: William N. Patterson, James H. Dupont, Richard D. Loehr, Henri Y. Kim, Garrett L. Hall, James M. Cook

Patent number: 8037822Abstract: A cost-effective solution is proposed to improve explosive transfer between booster and warhead that is compatible with the existing base of general purpose warheads and flexible to work with new warhead configurations. A booster lens is placed in the fuze well that concentrates the pressure wave to penetrate the fuze well with a peak pressure that exceeds the detonation threshold and detonate the warhead explosive. The booster lens can be configured to control the direction of the concentrated lobe to penetrate the fuze well where the barriers are low.Type: GrantFiled: January 6, 2011Date of Patent: October 18, 2011Assignee: Raytheon CompanyInventors: A.

Patent number: 8006623Abstract: A high-lethality fragmentation warhead with reduced risk of collateral damage to the warhead launch platform. High lethality is achieved with a forward-firing fragmentation assembly placed in front of the explosive and a side-firing fragmentation assembly placed in a void space in the aft section of the explosive. The risk of collateral damage to the launch platform is reduced by forming the case and explosive containment structures of materials that are pulverized upon detonation of the explosive. This substantially eliminates radial fragments and in particular fragments thrown back towards the platform. Performance may be enhanced by tapering the aft section of the containment structure and explosive to eliminate explosive that does not contribute to the total energy imparted to the forward-firing fragmentation assembly by the pressure wave to create the void space for the side-firing fragmentation assembly.Type: GrantFiled: November 17, 2008Date of Patent: August 30, 2011Assignee: Raytheon CompanyInventors: James H. Dupont, Henri Y. Kim, Travis P. Walter

Patent number: 7971535Abstract: The present invention provides a high-lethality low collateral damage fragmentation warhead. The case is formed of a material that is pulverized upon detonation of the explosive. As a result, the lethality radius of the pulverized case fragments is no greater than that of the gas blast, thus reducing potential collateral damage. Warhead lethality is improved by placing a pattern shaper between the fragment assembly and the explosive. The explosive and pattern shaper have a conformal non-planar interface that shapes the pressure wavefront as it propagates there through to expel metal fragments from the fragmentation assembly with a desired pattern density over a prescribed solid angle.Type: GrantFiled: May 19, 2008Date of Patent: July 5, 2011Assignee: Raytheon CompanyInventors: Henri Y.

Publication number: 20110094408Abstract: A forward firing fragmentation warhead is constructed with casing materials that are pulverized upon detonation of the explosive. As a result, the lethality radius of the pulverized case fragments is no greater than that of the gas blast, thus reducing potential collateral damage. Warhead lethality may be improved by forming the fragmentation layer and explosive with dome-shapes that approximately match the shape of the advancing pressure wave. This increases fragment velocity and improves the uniformity of the fragment distribution over the forward-firing pattern. A variable-thickness pattern shaper may be placed between the fragmentation layer and explosive to provide additional shaping of the forward-firing pattern. Warhead weight and cost can be reduced by eliminating explosive at the aft end of the warhead that does not contribute to the total energy imparted to the fragments.Type: ApplicationFiled: November 17, 2008Publication date: April 28, 2011Inventors: James H.
