Abstract: Disclosed are devices and methods for the destruction of an explosive device, such as mines and other unexploded ordnance, without the detonation of the explosive device. The devices comprise an explosive charge that penetrates and opens the casing of an explosive device and forces reactive material into the explosive device, thus neutralizing it.

Abstract: The invention provides a system and a method for determining the direction to a radiating source, for use by a vehicle guidance system, in which optical fibers are used to both collect and transmit optical signals in which the vehicle is preferably intended to home in on its target. The optical fibers disclosed herein require no separate collection optics, but instead directly collect incident radiation arriving at one end of the optical fiber for transmission to a photodiode detector coupled to the distal end. Preferably the radiation is laser radiation radiating from a target in relation to which the vehicle is guided, and preferably the vehicle is a guided missile. Elimination of collection optics reduces the complexity and cost of the apparatus and provides an unexpected increase in and selectability of the accuracy of directional determination by the system. The system includes an array of apertures disposed in selected, non-uniform locations on the vehicle.

Abstract: A staple and stapler for injecting the staple in a manner so that the staple maintains a near constant width upon penetration of material to be joined and during staple closure/forming such that material perturbation and staple to staple spacing may be minimized. The staple has a rectilinear bridge part from which depend oppositely positioned side parts and from the side parts a pair of straight legs. In a preferred embodiment, the oppositely positioned side parts consist of a proximal arcuate section attached to the bridge part and an oppositely directed distal arcuate section attached to the legs. The legs may have sharpened points. Also disclosed is a stapler adapted to force the oppositely directed distal arcuate sections outward, in one embodiment, thereby forcing a reaction of the legs of the staple to face each other in linear alignment and form a closed staple.

Abstract: The present invention pertains to the aerial deployment of generally planar structures. Typically, these structures are explosive arrays. Such explosive arrays are typically used in standoff minefield clearing and breaching on the ground, at river crossings, on beaches, and in shallow water surf zones adjoining beaches. The invention more specifically involves devices and methods for stably deploying such structures. This stable deployment is achieved by positioning the structure in a dihedral configuration as it moves through the air.

Abstract: A multiple squib assembly is provided for use in a chaff deployment system. A method of manufacture is also provided. The assembly of this invention represents an improvement over prior art squib assemblies, such as the BBU48. In preferred embodiments, the assembly comprises a brass base plate, a pair of squibs, a center contact connected to the squibs, and a zener diode connected between one of the squibs and the baseplate. All of those components are retained within a molded rubber or plastic body, which is shaped to hold the components in the desired relative position and to form sealing elements around each of the squibs. A reliable, integral assembly is thus provided using a minimal number of parts and electrical connections. In alternative embodiments, a larger number of squibs may be incorporated into the assembly, and alternative discrimination elements may be employed.

Abstract: In a shaped-charge device, the liner is so shaped that bulges are formed in the jet without causing the jet to deviate from the central axis. The shaped-charge device includes a case defining an axisymmetrical forwardly-opening cavity uniformly disposed about a central axis; an axisymmetrical, homogeneous-material, liner of variable thickness defining a forwardly-opening cavity having a closed apex, with the cavity being uniformly disposed within the casing about the central axis; and explosive material symmetrically disposed between the casing and the liner. The liner is so shaped that in response to the explosive material being detonated to thereby explode, the liner is progressively collapsed inward by the exploding material to be formed into a fluid jet of the homogeneous liner material that is forwardly expelled at a varying velocity from the casing along the central axis, with the forward portion of the jet being squeezed from the apex of the collapsing liner.

Abstract: An integrated spacing and orientation control system is provided for carrying an array of objects and maintaining a predetermined orientation of the objects and a predetermined spacing between objects. In a presently preferred application, the spacing and orientation system carries an array of anti-mine munitions for clearing a path through a minefield. The invention deploys the anti-mine munitions in a downwardly pointed orientation with proper spacing between munitions, even when the array of munitions is deployed using rocket motors.

Abstract: An inflatable truss frame member for use in the frame of a large inflatable device such as a ship or satellite decoy. A first embodiment, developed for use in satellite decoys, comprises three main inflatable tubes separated by shear load carrying interlacing inflatable tubes. The first embodiment may be manufactured by laminating two MYLAR sheets together using a triangular pattern of adhesive print to form a series of inflatable tubes. Excess material is removed from between the tubes and the edges of the MYLAR are bonded together forming a cylinder to complete the inflatable truss frame member. A second embodiment, developed for the heavier shear loading of ship decoys, comprises three main inflatable tubes separated by a shear load carrying web. The second embodiment may be manufactured by bonding an inner and outer tube made of MYLAR along arcuately spaced strips. The bonded MYLAR forms the separating web and unbonded MYLAR forms three inflatable tubes.

Abstract: An incriment optical signal from a potential enemy threat is captured by an array of apertures which are connected to a number of broadband filters. The broadband filters have overlapping band pass regions to cover the wavelength spectrum of potential threats, but not with the spectral resolution of a larger number of narrowband filters. To further increase resolution without adding additional filters, each broadband filter is connected to an optical delay line which converts wavelength into a time delay. To enable measurement of the time delay, additional optical lines with no relative delay are connected directly from the apertures. The time difference between when a signal arrives over optical delay lines from the filters and when a signal arrives over optical lines directly from the array of apertures is then reconverted to wavelength to a high degree of resolution.

Abstract: An electronic countermeasure (ECM) simulator which fits into the housing of any actual ECM payload device and substitutes electrical components for the chaff, flares or other countermeasures which are emitted into the environment. The ECM payload simulator electrically verifies firing ability for any ECM dispensing system using a magnetic indicator which sets when the electrical signal required to fire an actual ECM payload device operates properly. The magnetic indicator can be viewed, tested and reset by a ground crew upon return of the aircraft to ground. The magnetic indicator has a parallel resistor so that the aircraft's arsenal inventorying device will indicate an unfired ECM payload device. An optional radio frequency (RF) transmitter may be substituted for the magnetic indicator to send coded transmissions to a radar site while in flight.
