  • Publication number: 20130177469
    Abstract: Methods comprising providing a composition comprising iron and a high melting point element; heating the composition to an elevated temperature up to about 3,500° F.; holding the composition at the elevated temperature for a time sufficient for the heat's temperature to stabilize; and allowing the composition to cool or solidify. Methods comprising providing a master alloy comprising iron and up to about 30% by weight of a high melting point element; and adding the master alloy to a heat of steel. Compositions comprising an alloy of iron and high melting point element in which the alloy is up to about 30% by weight of the high melting point element. Compositions comprising an alloy of iron and high melting point element having a substantially uniform microstructure.

  • Patent number: 8464639
    Abstract: A fuse booster system for a reduced collateral damage bomb or penetrating warhead is described and disclosed. The fuse booster system uses shaped charges that will ignite the main high explosive charge of the bomb or penetrating warhead, and also remove portions of the bomb or penetrating warhead to reduce the power of the bomb at the target in a measurable manner to control the lethality and collateral damage of the bomb or penetrating warhead.

  • Publication number: 20120234197
    Abstract: A reduced collateral damage bomb (RCDB) bomb casing is described and disclosed along with the system and method for making it. The RCDB bomb casing may be formed from conventional or penetrating warhead bomb casings. The RCDB bomb casing has a filler material/materials disposed on the interior walls that will assist in controlling the collateral damage caused by the finished bomb but not prevent the appropriate destructive power being delivered to a selected target. Further, the fusing system may include a shaped charge to control the ignition of the main explosive charge to control the amount of collateral damage when the bomb casing is filled with high explosives.

  • Publication number: 20110168048
    Abstract: A bomb and penetrating warhead (“PW”) casings is disclosed that has three or more exterior facets. The facets may be straight or spiraling. The resulting bomb or PW casing that results is a stronger, tougher structure that will increase the overall performance of the bomb or PW casing in delivering the desired destructive power to a selected target. The bomb and PW casings also have the advantage of being lighter in weight than a conventional bomb structure but yet provide the desired destructive power to the selected target.
