  • Propellant charge arrangement for barrel-weapons or ballistic drives
    Patent number: 6334394
    Abstract: A propellant charge arrangement for barrel-weapons or ballistic drives comprises a conventional core charge having an ignition system and a consolidated propellant surrounding the core charge and having its own high electrical energy ignition system which can be controlled in a time-delayed manner after triggering the core charge ignition system. The structure and arrangement of the consolidated propellant and its ignition system are chosen such that, during combustion of the core charge, the consolidated propellant disintegrates into fragments of essentially uniform geometry in response to triggering of its associated ignition system, wherein the fragments are accelerated into the gas volume generated during combustion of the core charge.
