Multiple kill vehicle (MKV) interceptor and method for intercepting exo and endo-atmospheric targets
Patent number: 7494089Abstract: By sharing tasks between the CV and the KVs, the MKV interceptor provides a cost-effective missile defense system capable of intercepting and killing multiple targets. The placement of the acquisition and discrimination sensor and control sensor on the CV to provide target acquisition and discrimination and mid-course guidance for all the KVs avoids the weight and complexity issues associated with trying to “miniaturize” unitary interceptors. The placement of a short-band imaging sensor on each KV overcomes the latency, resolution and bandwidth problems associated with command guidance systems and allows each KV to precisely select a desirable aimpoint and maintain track on that aimpoint to impact.Type: GrantFiled: November 23, 2005Date of Patent: February 24, 2009Assignee: Raytheon CompanyInventors: Darin S Williams, Kent P.

Patent number: 6796244Abstract: A ballistic projectile (10) includes a body (12) defining a hollow, open-ended payload cavity (22) covered by means of a cover portion (26) fitting as a spigot into a socket (12.1) defined by the body (12). Peripheral seats in the form of grooves (32), (34) are provided in register in peripheral slide surfaces of respectively the cover portion (26) and the body (12) forming the spigot-socket combination. A peripheral, discontinuous shear ring (36) is received within the respective grooves (32), (34) to bridge the interface and thus to lock the cover portion to the body. Pressure selectively generated in the payload cavity shears the ring (36) to allow parting of the cover portion to expose the payload cavity.Type: GrantFiled: April 3, 2003Date of Patent: September 28, 2004Assignee: Denel (Proprietary) LimitedInventor: Petrus Hugo Loubser

Patent number: 6789484Abstract: Projectiles or war-heads with an inner arrangement for the formation of bulging zones (4,4a) are proposed, comprised of an enclosed bulging medium (1) which is terminal-ballistically substantially ineffective and is radially enclosed by a penetration material (2) which is terminal-ballistically effective, with the bulging medium (1) having a lower density as compared with the enclosing penetration material (2). This leads to the effect that on impact or on penetrating a target plate (3) the bulging medium (1) remains behind relative to the encompassing terminal-ballistic effective body (2) and is laterally increasingly bulged by the bulging material (1) which continues to flow in from behind. As a result of the high pressures, a conical (crowned) pressure and bulging zone (4,4a) is formed dynamically, which zone radially widens or fragments the passing ambient effective material (5,5a).Type: GrantFiled: August 4, 2003Date of Patent: September 14, 2004Assignee: furturtec AG c/o Beeler + Beeler Treuhand AGInventor: Gerd Kellner

Patent number: 6766746Abstract: A mission responsive ordnance includes projectiles arranged in a bundled configuration that defines a substantially solid structure with each of the projectiles forming a geometric portion thereof. In a unitary mode of operation, the bundled configuration is maintained to define an integral structural element that bears loads generated when the bundled configuration strikes and penetrates a target. In a sub-divided mode of operation, the projectiles are un-bundled before a target is struck so that the projectiles are released into a surrounding environment.Type: GrantFiled: September 5, 2003Date of Patent: July 27, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Timothy L.

Publication number: 20040139877Abstract: A cargo device (1) carrying submunitions and incorporating guidance and target seeking functions. The triggering or actuation of the submunitions is determinable by means of a programming function on the ground or on board another weapon platform or via a link from the ground or said weapon platform. The submunitions are also actuatable by impact function. The programming function incorporates or interacts with mode determining devices that cause the cargo device and its submunitions to operate either in a penetrator mode, in which the submunitions are essnetially conjoined in a common griggering or actuation function, or in a separation mode, in which the submunitions sequentially leave the cargo device and thereby function with individual triggering or actuation functions that are independent from, or co-ordinated with, the triggering or actuation functions of the other submunitions.Type: ApplicationFiled: August 20, 2003Publication date: July 22, 2004Inventors: Torsten Ronn, Ulf Heiche
