Abstract

Abstract A device for ejecting ammunition containers from a war head has transverse to the war head longitudinal axis a bellows, which holds the ammunition containers in a plurality of concave pockets. The bellows is inflated by a gas generator including a gas-permeable tube extending along the longitudinal axis. In order to achieve a wide range of variations in the behavior of the ammunition containers in the process of being ejected, a propellant charge of the gas generator is particulate, with at least one ignition cord extending along the longitudinal axis of the tube around which a particle ignition mixture is arranged, so that the hot particles during burn-down of the ignition mixture are pressed between the particles of the propellant charge. A daming serves for building up the initial pressure required for the burning down of the propellant charge.
