A closure ring is disposed in said aft portion, a vent also being provided in said aft portion. The warhead casing is filled with a predetermined level of explosive material. Preferably the explosive composition contain reduced amounts of explosive material and a strong oxidizer. The warhead assembly possesses superior penetration and blast performance, as well as superior Insensitive Munitions characteristics.

Abstract: Reactive foils and their uses are provided as localized heat sources useful, for example, in ignition, joining and propulsion. An improved reactive foil is preferably a freestanding multilayered foil structure made up of alternating layers selected from materials that will react with one another in an exothermic and self-propagating reaction. Upon reacting, this foil supplies highly localized heat energy that may be applied, for example, to joining layers, or directly to bulk materials that are to be joined. This foil heat-source allows rapid bonding to occur at room temperature in virtually any environment (e.g., air, vacuum, water, etc.). If a joining material is used, the foil reaction will supply enough heat to melt the joining materials, which upon cooling will form a strong bond, joining two or more bulk materials. If no joining material is used, the foil reaction supplies heat directly to at least two bulk materials, melting a portion of each bulk, which upon cooling, form a strong bond.

Abstract: The non toxic bipropellent of the present invention contains a non-toxic hypergolic miscible fuel (hereinafter referred to as “NHMF”) and a rocket grade hydrogen peroxide. This NHMF has rapid ignition capability and minimizes the formation of precipitate, even when exposed to extreme heat or water. The NHMF of this invention contains 5 species. Namely, a polar organic species miscible with hydrogen peroxide; a propagator, which may be substituted or unsubstituted amines, amides or diamines; an inorganic metal salt, which reacts to form a catalyst in solution or as a colloid; acetic acid; and alkali acetate. The inorganic metal salt is miscible with the polar organic species and the propagator in solution.

Abstract: The invention relates to a process to manufacture an object using at least one granular material (16) having a large particle size, for example greater than or equal to 0.1 mm, such process being characterised by the following stages: the granular material or materials are placed in a mould (2) at the same dimensions as the object to be made and incorporating at least one evacuation opening (6), said opening being of a size that is less than the particle size of the material, a liquid-phase binder (21) is poured into the mould, the binder is mixed between the grains of material and the excess binder is drained off through the evacuation opening using suction means (11). Application in the manufacture of igniting tubes or propellant charges for artillery ammunition.

Abstract: This substantially water-free method for preparing high density igniter granules involves uniformly coating fuel and oxidizer particulates dispersed in a non-solvent with a thermoplastic elastomer solution to produce coated igniter granules exhibiting substantially uniform size and shape distributions. The coated igniter granules are especially useful for waterless extrusion into igniters for automobile gas generating inflation devices, solid propellant rocket motors, and thrust decoys.

Abstract: This invention pertains to an article that emits infrared radiation for a period of about 15 minutes or more, depending on the size and shape, and to a process for preparing the article. The article includes, in a preferred embodiment, a combustible aerogel or other nanocellular substrate with iron metal impregnant formed by thermal decomposition of iron pentacarbonyl deposited on and in the substrate in an amount of at least about 5% or at least about 20% of the weight of the substrate, depending on the substrate. The impregnant reacts exothermically on contact with air or an oxygen-containing gas and imparts sufficient energy to the substrate to cause it to burn for about 30 seconds to about 30 minutes depending on size and shape, thereby emitting infrared radiation. The process pertains to deposition of the impregnant on and in the substrate by flowing a carrier gas saturated with the impregnant precursor over and through the substrate.
