Rebounding Or Multiple Bursting Charges Patents (Class 102/394)
  • Patent number: 9982978
    Abstract: The present invention relates to warheads with blast wave conditioners and in particular to devices for quickly removing a door to permit entry through the doorway. It discloses a device and method of shaping the pressure wave pattern by the use of inert material. The inert material of the present invention is used to reduce localized directional effects occurring at the point of impact, instead generating a more diffuse pressure-wave pattern across the target surface.

  • Patent number: 9080842
    Abstract: The invention provides a system, device and method designed to detect, alert and identify unwanted entry into areas by intruders. The invention is also designed to prevent escape from secured facilities. If escape from such a secured facility is realized, the system will identify and mark the intruder or escapee for immediate or later capture by local and or federal law enforcement authorities. The system will accomplish this by mechanical, electronic and chemical means. The system is also designed to be a territory denial system. Although the system will accomplish its means by clandestine deployment, the unseen but known presence of the device will cause a profound psychological block to any would be intruder to a given area that it is deployed in. The devices are deployed below ground just below the surface as a non-lethal landmine and subterranean several feet below ground as an anti-tunneling device.

  • Patent number: 8800448
    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: 6895864
    Abstract: The present invention relates to a segmented subcaliber projectile (1) subdivisible into a number of separate segments contiguous with each other at least initially to form an integral projectile of united segments or submunitions (5). The advantage with this subcaliber projectile is that since the segments or submunitions (5) are arranged sequentially after each other, each one comprises an explosive charge (7) initiatable by a very powerful shock and encased in an outer casing (6) of hard material such that the projectile in integral form can be used directly against heavy armor, and by means of dispersion of the various segments can also be used against aircraft.

  • Patent number: 6079334
    Abstract: Shell for trench mortars and similar firing systems, which shell includes an effective portion, which can be fired from a barrel by a propellant charge, there being a pressure plate provided between the effective portion and the propellant charge, which pressure plate carries the influence from the propellant charge. To provide effective fire above the ground a support portion is releasably arranged in front of the effective portion in the firing direction. The support portion carries a second propellant charge and in its front end a percussion cap, which, when the shell is fired, is located partly exposed outside the front end of the support portion and initiates the second propellant charge when hitting ground.

  • Patent number: 5341343
    Abstract: An explosive actuated acoustic device emits sound to be used in torpedo countermeasures. Numbered devices are delivered over an extended area and sink through the water. The devices are actuated at different times as they sink, to provide sound masking over an extended period of time. The devices also include safety devices which prevent premature actuation from jarring or jolting and from impact with the water.

  • Patent number: 5109774
    Abstract: Disclosed is a new type of penetrating projectile, the penetrating capacity of which is improved and more efficiently controlled, notably through a solution to the problems of obliquity. A projectile of this type has a front element forming the active part, fixedly joined to a tube. The tube has a closed end which contains a propellant charge for the propulsion of the element and an igniter for the charge, responding to the impact of the element on a target. In reaching the target, the projectile penetrates it slightly under the effect of the velocity and it is only at this instant, or slightly after it, that the penetration proper takes place. The penetration thus takes place without obliquity. This projectile can be used as an individual munition or sub-munition.

  • Patent number: 5070790
    Abstract: A marker that can be used to increase the precision and efficiency of the guidance of homing heads towards a target. In order to mark targets on land, this marker has: an ovoid casing provided with a firing fuse, and a magnet and a coil for detecting flux variations during an impact on a magnetic surface. Inside the casing there are: a battery, an electronic control and transmission circuit, and a cylinder of thrustors connected to one another by pyrotechnical delaying mechanisms. The cylinder opens out on to a single nozzle which is inclined with respect to the axis of the casing. After impact on the ground, the electronic circuit controls the firing of the first thrustor. The other thrustors cause leaps until the marker gets fixed to a magnetic surface, through the magnet.

  • Patent number: 4372215
    Abstract: The invention concerns a process and apparatus for transporting and dropping a plurality of charges contained in a single container. Within the shell of the container is arranged a plurality of modules, the bodies of which contain a charge, which may particularly be military; said modules are extracted one by one, upon command, through the rear of the shell. This extraction can take place only if a general mechanical control element has moved from a position called the "safety" position to a position called the "cocked" position, a movement which can take place only when the means for fastening the container has been released from the lug holding it to the carrier vehicle. The invention is applied particularly to modular bombs having fragmentable modules designed for neutralization of relatively widespread ground targets.

  • Patent number: 4356770
    Abstract: In a munitions system, a cylindrical canister is fired over a target. The canister carries a target sensing infrared device and, when a target is detected, a projectile is fired downward from the bottom of the overflying missile. A spinning motion is imparted to the missile to stabilize its flight, and a wobbling motion is imparted to the missile to provide a larger target area. The projectile forms a concave lower end to the missile and is fired by an explosive charge.

  • Patent number: 4296685
    Abstract: A plurality of warheads are disposed for ejection one behind the other, axially in a load-carrying missile with slave missiles disposed in firing tubes and parachutes connected to the warheads and causing their directional, braked descent in the target area. Proximity fuses cause the firing of the slave missiles. Each warhead consists of a firing tube which is open at both ends and in which two slave missiles are disposed with a common propellant charge between them. A parachute of each of the warheads is secured to the firing tube intermediate its length.
