Abstract

1. Multi apertured bulk propellant charge granulate shaped by extrusion moulding and with progressively variable combustion, characterised by the fact that an individual granule (30) separated from the extruded strand has the shape of two end surface zones (38, 39), altered by a process which preselectably changes the original circular cylindrical shape, the outlet openings (22, 44) of the apertures (20) being substantially reduced to the point where they are completely closed up.
