    Abstract: This invention generally relates to a method and apparatus to neutralize ordnance, more specifically improvised explosive devices (IEDs) and unexploded ordnance (UXOs). The current invention provides a simple method to neutralize the ordnance by taking advantage of a new class of energetic materials that includes nano-thermites, binary thermites and additionally powdered thermites. In the invention, a projectile is loaded with the new class of energetic materials and fired into the ordnance. The impact causes the energetic materials to react in such a fashion that the explosive compound or other material within the IED or UXO is burned in a self-propagating mode without exploding. Hence, the ordnance is neutralized.

A method of guiding a projectile can include firing a projectile at a target, tracking the projectile and the target, determining a desired change in a flight path of the projectile, transmitting guidance commands to effect the desired change in the projectile's flight path to the projectile, receiving the guidance commands onboard the projectile and selectively igniting an explosive cell in a matrix of addressable explosive cells contained in a common substrate using the guidance commands.

  • Publication number: 20110226148
    Abstract: An apparatus and method for disrupting or destroying a component of an electronic device is provided. In one example, an electronic device includes a memory for storing data and a combustion device disposed therewith, the combustion device comprising a volume of electrically ignitable propellant disposed to render the memory at least partially inaccessible after combusted. For example, the combustion device could damage the memory itself or another component of the electronic device, such as a controller or read head, thereby rendering the data inaccessible. In some examples, the memory may include a magnetic storage material such as a magnetic hard drive and the combustion device may be disposed and operable to provide demagnetization of the storage material when combusted. In other examples, the combustion device may merely destroy or render inoperable the read head or other components of the electronic device needed for accessing stored data.

  • Publication number: 20110100245
    Abstract: A method and apparatus for incorporating nanophase elemental materials and metastable interstitial composite materials into projectiles, projectile fragments, ordnance casings, warheads and structural components. The projectile, fragments and casings include an elemental material capable of oxidizing. A coating material that is capable of preventing oxidation of the elemental material and an oxidizing agent may be present and be capable of reacting with the elemental material so that a self-propagating high temperature synthesis reaction from a stabilized solid material is yielded for the purpose of rendering terminal effects or thermal impact to a target at impact.

  • Publication number: 20110011295
    Abstract: A kinetic fireball incendiary munition is provided having an outer shell or bomb casing, one or more incendiary submunitions therein, and an igniter therefore. Each of the submunitions includes an incendiary portion, at least one rocket motor that propels the submunition inside of a target volume, and an oxidizer for the incendiary portion and rocket motor. The submunitions liberate sufficient heat to produce elevated temperatures inside of a target structure to thermalize the contents thereof without creating a substantial overpressure or explosive effect. The incendiary portion includes a solid propellant and, optionally, one or more energetic materials selected from the group consisting of phosphorous, boron, magnesium, aluminum, Fluorinert™-aluminum and BKNO3. The incendiary submunition may be in the shape of a ball or a circular disk with a rocket motor therein.

    Abstract: An arrow-type warhead (100,200,300,400,500,600,700) comprises an envelope (102,202), a filling (108), a hardened head section (104) to promote penetration of the target and a stabilizing mechanism (106,210,302,402,502,602) to stabilize the warhead in flight, hi some embodiments the filling (108) is pyrophoric and undergoes an exothermic reaction with the envelope upon impact. In other embodiments the filling is incendiary and undergoes reaction with the envelope upon impact in an oxygen rich-environment. In yet other embodiments, the filling is explosive. In all embodiments, the warhead may be equipped with a mini-rocket propulsion mechanism (802) for propelling the warhead to the target.

  • Publication number: 20100275803
    Abstract: A diversionary device has a housing having dimensions which are selected such that when the device is thrown or dropped, the device will come to rest only on one of its two primary sides. Each primary side has a circular dispersion port formed therethrough. The device includes means for blocking the first dispersion port if the device comes to rest on the first primary surface and for blocking the second dispersion port if the device comes to rest on the second primary surface. A firing mechanism is operable to discharge an ignitable composition out of a removable cartridge within the housing. The ignitable composition is discharged through the first dispersion port when the device rests on the second primary side and through the second dispersion port when the device rests on the first primary side. The composition then forms a cloud above the device and may be ignited.
