  • Patent number: 10082376
    Abstract: A projectile has a liner forming an interior void, and a core disposed in a first region of the void proximal to a trailing end portion of the liner, with a portion of the void disposed forward with respect to the core. An outer jacket covers a leading end portion of the liner to enclose the interior void. When the projectile impacts a target object, the core travels in a direction of flight through the leading end portion of the liner to impact the object. When the projectile impacts a target surface at a non-zero angle of approach with respect to the normal of the target surface, the projectile creates a deformation in the target surface immediately before the core travels through the leading end portion of the liner to impact the target. This deformation reduces the probability that the core will ricochet off the deformed portion of the surface.

  • Publication number: 20130199395
    Abstract: A stand-off breaching device, for breaching a target, that includes a nose at a front end which is a rounded cone-shape and configured to cause the stand-off breaching device to rebound from a target after the nose impacts the target, and a body connected to the nose and extending to a back end of the stand-off breaching device. The body includes a main explosive fill that is detonated and explodes to provide an explosive breaching force, and a delay detonator that detonates the main explosive fill and that is triggered when the nose impacts a target. The delay-detonator is configured to delay detonation of the main explosive fill until the stand-off breaching device has rebounded to a determined stand-off distance chosen to cause effective breaching of the target. The nose, body, and their components are fabricated from material that will be substantially consumed by the explosion, minimizing any fragments.

  • Patent number: 8181576
    Abstract: A projectile for safe standoff destruction of explosive devices. The projectile's casing encloses a chamber containing combustible material located opposite a roughened surface on the chamber. The combustible material is mounted so upon the projectile impacting the explosive device, the combustible material flies onto the roughened surface, heating the material by shear forces and igniting the material. This creates pressure bursting the chamber, injecting combustion gases into the explosive fill within the device, thereby igniting the fill locally at the impact, and along cracks in the fill. This arrangement prevents a coherent detonation wavefront from forming within the fill, and a slower burn of the fill, whereby a rifleman has little chance of receiving a concussive shock, or shrapnel, from the device.

  • Patent number: 6135028
    Abstract: A penetrating, dual-mode warhead having soft target, surface burst mode and a hard target, penetrating mode is provided. The warhead has a cylindri outer fragmenting shell which contains an explosive surround. A long-rod penetrator with an explosive payload is located within the outer fragmenting shell. By arming selection prior to launch, the warhead can be configured for the surface burst mode which uses proximity sensor to initiate the outer shell explosive. The outer shell initiates the penetrator payload thereby detonating both explosives and fragmenting both the shell and penetrator casing. In the penetrating mode, the outer shell is stripped away on impact but is initiated just as the penetrator exits the shell. By this method the penetrator remains undamaged, but the outer shell nevertheless detonates to engage any surface targets. The penetrator continues into the hardened target, detonating on either a void sensor or on timing, whichever occurs first.

  • Patent number: 5945629
    Abstract: A fuse-less ballistic explosive projectile (1) with a great fragmentation effect has a secondary explosive (50) with a special structure (75), the secondary explosive detonating upon impact. The secondary explosive (50) surrounds within a projectile cap (24) a conical projection (30) of a penetration core (18). Transmission of the firing effect from the secondary explosive (50) is effected through a central through bore (40) of the penetration core (18) to a large-volume bursting charge (60) arranged in a projectile body (10).

  • Patent number: 5939662
    Abstract: A hard-target penetrating warhead (10) adapted for use with length constrained warhead payload bays. The warhead (10) includes a warhead case (12) for containing warhead explosives (22, 27). A tungsten ballast (16) is disposed within the case (12) for providing a high warhead sectional pressure upon impact of the warhead (10) on a target. A fuse (19) detonates the warhead explosives (22, 27) upon penetration of the target. The fuse (19) is housed by a fuse well (18) that is attached to the case (12) at one end. A slip fit section of the fuse well (18) provides structural support to the case (12) and prevents dislodging of the fuse well (18) and the fuse (19) from the case (12) upon warhead target impact. Explosives blowout ports (24) included in the fuse well (18) inhibit undesirable explosion or detonation of the warhead explosives (22, 27) by accidental exposure to high heat or fire. In a specific embodiment, the case (12) has a 6 caliber radius head nose (14).

  • Patent number: 5872324
    Abstract: A trimode fuze is provided which comprises a combination of a standard dual ode fuze with the addition of a void sensing mechanism. The modified fuze provides detonation of a warhead under three distinct scenarios: impact upon a hard target with detonation caused by the deformation of the warhead, displacing the hard target firing pin, penetration and continuous deceleration within a solid target with detonation caused by the expiration of a penetration delay timer, and penetration of a soft target with detonation caused by the transition from a target impact deceleration to the lower preset deceleration threshold.The first two modes of detonation are similar to those found in prior art dual mode fuzes. The third mode is brought about when target impact deceleration causes compression of a spring. As the spring compresses, steel balls slide out of a locking mechanism.

  • Patent number: 5705766
    Abstract: A fuse (12) detonates a spin-stabilized projectile (10) after the fuse (12) experiences a preset number of turns. The preset number is communicated (64) to the fuse (12) prior to launch. A semiconductor piezoelectric strain gauge (26) senses stress and provides a signal which is responsive to centrifugal forces experienced by the sensor (26) as a result of projectile spin. A microcontroller (30) repetitively digitizes and translates the sensor signal to determine turn numbers, which the microcontroller (30) integrates to determine the total number of turns experienced by the fuse (12) since launch. When the accumulated turn number reaches (94) the preset number, the fuse (12) detonates the projectile (10). However, an arming duration (76) must have expired before the projectile (10) can detonate, and the projectile (10) can detonate at any time following the expiration of the arming duration when an impact is detected.

  • Patent number: 5691502
    Abstract: A plurality of objects is deployed in generally radial directions at low velocities in order to achieve a predetermined pattern of the deployed objects. The device has a metal inner wall member (20, 120) having a plurality of annular cylindrical segments of differing outside diameters, an explosive body (22, 122) of low velocity explosive, and a plurality of arrays (40, 140) positioned coaxially with and exteriorly of the explosive body (22, 122) and spaced along the length of the explosive body (22, 122). Each array (40, 140) comprises a plurality of objects (28). The explosive body (22, 122) can be in the form of a plurality of annular sections which provide the objects (28) in each array with an amount of energy different from that provided to each of the objects in the adjacent array. An annular flange (32) can separate the forward end of the explosive body (22, 122) from a booster ring (66), or the booster ring (166) can be positioned within a central cavity of the inner wall member (120).
