  • Patent number: 6591753
    Abstract: A propellant device of consisting of a compact charge and a firing system for pipe weapons or ballistic drives is proposed. At least one electromagnetic radiation absorbing medium, e.g. carbon black, is dispersed in the compact charge and can be activated by means of a firing system emitting electromagnetic radiation. The compact charge is thereby disintergrated in fragments through triggering of the firing system and the fragments are accelerated into the gas volume produced during burning of the compact charge. The inventive propellant device avoids the use of chemical firing as well as mechanical firing means. Moreover, fragmentation of the compact charge permits maintenance of the produced maximum pressure over a longer period of time to impart a higher muzzle velocity to an object to be accelerated, e.g. a projectile, a rocket or the like.
