Abstract: A fragmentation pattern is formed on a surface of a warhead using a lithographic process. A photoresistant material is coated on an interior surface of the warhead casing. A portion of the photoresistant material is selectively cured by projecting an image of the fragmentation pattern onto the photoresistant material. The uncured portion of the photoresistant material is removed and an etchant is applied to the exposed portion of the warhead casing surface thereby etching the fragmentation pattern. Alternatively, a protective coating is applied over the entire surface thereby creating the fragmentation pattern.

Abstract: A cluster munition may include a plurality of submunitions that are ejected from a delivery vehicle. Each submunition is single target discriminating and includes electronic self-destruct and self-deactivate capability. Each submunition includes a microprocessor and a wireless communication device connected to the microprocessor. Each submunition includes a deployable antenna/stabilizer that functions as an antenna for the wireless communication device and as a stabilizer to stabilize the descent of the submunition. Optionally, the deployable antenna/stabilizer may also facilitate ejection of the submunition from the delivery vehicle. The submunitions may wirelessly communicate with each other and with other entities.

Abstract: A venting lifting plug is provided for an unfuzed munition having a fuze cavity with internal threads, the venting lifting plug is formed of a threaded ring having both internal and external threads together with a lifting plug having a lifting ring, a neck and a round portion having external threads, external threads on the threaded ring being in threaded engagement with internal threads on the fuze cavity of the munition, internal threads on the threaded ring being in threaded engagement with external threads on the lifting plug, and a threaded joint formed between the lifting plug and threaded ring is soldered together with one or more eutectic materials having a melting point lower than a predetermined critical temperature of cook-off gases from the munition.

Abstract: The present invention shows an apparatus and method for the determination of clearances for safety of personnel and safe storage of critical assets within a structure. The method comprises the steps of choosing appropriate test locations on top of the structure, using a test apparatus including a signal generator, a receiver and a computer, injecting low-level test currents at each test locations, measuring the resulting electromagnetic fields; calculating the transfer functions for the structure, and determining the internal energy levels that lightning strikes would cause inside the structure in order to determine a safe stand-off distance for critical assets or personnel within the structure.
