There is provided a mold apparatus and process whereby a warhead body can be fabricated in a single over molding process which may also include therein metal fragments, metal balls, obturators, boat tails and other aerodynamic features, metal rings and/or threads. Other molds and processes are presented whereby a warhead body may be over molded in a polymer matrix in sequential steps which may include adding therein metal balls, then fragments, and any of obturators, boat tails and other aerodynamic features, metal rings and/or threads, as desired. Still another process for fabricating a warhead body is presented whereby an insert section is first preloaded with metal fragments and covered with a skin, then the insert section is inserted into an oversized area in a mold, and polymer is then loaded around the insert section to form a unitary warhead body.

Method for sequentially fabricating a cartridge casebody through injection molding

A munition is rendered less sensitive to inadvertent initiations by providing a polymer liner on the entire inside surface of the munition. A thermoplastic liner may be fabricated totally within an empty inert munition casing by spraying a layer of electrostatically charged low melt thermoplastic material particles over substantially the entire inside surfaces of the munition casing, which casing is first electrically grounded. After thickening the particle layer through heat, further such layers may be then applied there over, until a desired cumulative thickness liner is fabricated.

Insensitive munitions liner

A lightweight composite sabot useful in large, medium and small caliber rifled gun systems, wherein each of the sabot segments are reinforced with thin aluminum, or other, metal wedges to increase the torsional strength of the sabot body to survive the torsional forces created when fired from a rifled gun tube. And, which composite sabot also has a metal bulkhead about the periphery thereof, to reduce the spin and resulting hoop stresses, and to help protect the composite material during firing.

Composite sabot

An IM type steel cartridge whose base contains a central bore there through&#x2014;within which bore is a steel base plug holding a primer cup, the base plug being held in place by a low melt, 220 to 250 degree F. melt eutectic solder&#x2014;wherein, if the cartridge is subjected to an unforeseen thermal or kinetic event, the solder will melt, the base plug ejected, and the propellant will vent rather than explode. The solder bond between the base plug and the cartridge case within which it is held is capable of resisting the from about 72,000, to up to 90,000 psi, force generated within the firing chamber of the weapon by the ignition and firing of the cartridge.

Riveted cartridge venting

An improved 25 mm linked cartridge IM ammunition storage system, using existing ammunition cans, that simplifies the design of the storage system, and utilizes standoffs to separate the base of each cartridge from the ends of the ammunition can&#x2014;thereby allowing the cartridges base IM venting system to vent properly, avoiding pressure build-up, and reducing the risk of explosion or detonation of the propellant.
