  • Patent number: 8739671
    Abstract: A method is provided for producing a large-calibre explosive projectile having a projectile casing with an ogival front part, which surrounds an internal area filled with a plastic-bonded explosive charge and, at a nose end, has a mouth closed by a nose fuze, wherein an elastic liner is arranged between the explosive charge and the inner wall of the projectile casing. The projectile casing is produced in two parts, such that, in the direction of the longitudinal axis of the projectile casing, a tail-end projectile casing section and an annular front projectile casing section, which contains the mouth, can be connected to one another in the area of the ogival front part, via a screw connection. The liner is introduced into the tail-end projectile casing section and the explosive charge is introduced into the liner before the two projectile casing sections are connected to one another.

  • Patent number: 8707843
    Abstract: The present invention provides an improved kinematic countermeasure flare and method of constructing the same wherein the housing has integrated internal features. The flare nose weight is set at the end of a die core prior to molding for integration with the housing. Longitudinal grooves and other recesses in the die core allow for the formation of internal longitudinal ribs which propellant can bond to and a retaining bead for retaining the nose weight in the housing which are integrated with the housing. Propellant is cast into the formed housing. A propellant shaping mandrel is then inserted into the formed housing thereby forcing the propellant into the internal cavity created by the integrally molded longitudinal ribs, the shaping mandrel and the wall of the flare housing such that the propellant is bonded to the interior housing wall and the longitudinal ribs.

  • Patent number: 6789485
    Abstract: Assembly of a gas generator 10 includes the step of adding uncured silicone to a propellant cup 25. Granulated oxidizer is then added over the top of the silicone and allowed to disperse therein. Afterwards, the silicone is cured to provide flush communication with an inner wall 14 of the propellant cup 25. Other granulated gas generant constituents may be added as well. A gas generator 10 assembled in this manner provides more predictable burn rates of a gas generant composition 26 and therefore more predictable performance of the gas generator 10.

  • Patent number: 6635197
    Abstract: A method and apparatus for casting a molten material using a phase-change material. A funnel means is provided that includes a reservoir containing a phase-change material. The funnel means is used in conjunction with a mold. The phase-change material is heated to a temperature above its melting point. A molten material is poured into the mold, and an excess amount of the molten material is retained in the funnel means after the mold is filled. The latent heat of fusion of the phase-change material provides heat to the funnel means as the phase-change material changes from a liquid to a solid. The heat from the phase-change material maintains the temperature of the molten material within the funnel above its melting point as the molten material within the mold begins to solidify and contract, thereby permitting the excess material within the funnel means to feed into the mold and fill any voids or porosities formed by the contraction of the material within the mold.

  • Patent number: 6520089
    Abstract: A method for setting and igniting a charge of explosives for geological investigations, comprising the following steps: a hole (14) is drilled in the ground (12) which is to be investigated; an explosion chamber (22) is hollowed out, whereby said explosion chamber has an expanded form in relation to the bore hole (14) at the end of said bore hole (14); an ignition element (34) and an explosive container (36) containing an explosive in a protective blister (54) surrounding the ignition element are lowered down into the explosion chamber (22); the explosive (42) is pressed out of the explosive container (36) into the explosive chamber (22) and the ignition element (34) is ignited In comparison with conventional methods, the inventive method provides for a considerably smaller diameter of bore hole, whereby said bore hole is substantially easier to drill.

  • Patent number: 6360666
    Abstract: An apparatus for use in filling and capping artillery charge system modules or the like including a lower fixture carried by a base plate for receiving a module with an open center core tube and fixing the module in place relative to the base plate for filling and capping. An upper fixture is carried by a pivot plate for capping a filled module, the pivot plate being hingedly attached with respect to the lower fixture to enable the upper fixture to swing clear of the lower fixture during module loading and thereafter addressing a fixed module to cap same. The lower fixture further includes a centering rod that carries a peripherally disposed flexible expanding member and a shaped cam lock member which operate the expander member to receive, lock and unlock a center core tube to the centering rod to capture and fix the module in place. The cam lock member also aligns the system for lid insertion by an adjustable stroke air cylinder mounted on the pivot plate.
