Abstract:
Propellant charge module (1) for artillery guns, comprising a predetermined quantity of propellant powder (12) enclosed in a preferably rigid cylindrical container (1) made of a combustible material, outwardly delimited by an outer cylinder wall (3) adapted to the calibre dimensions of the artillery gun, two essentially plane gable walls (4, 5) defining its ends, and a centrally arranged inner cylinder wall (10) which extends axially through the propellant charge module (1) and in turn defines a central ignition channel (11) which is delimited from the propellant powder and whose boundary wall is made up of a relay tube (10) of pyrophoric material, in at least the central part of which, as seen in the longitudinal direction, at an equal distance from the ends of the relay tube (10), there is arranged a firing charge in the form of a number of firing charge rings (14) which are arranged in succession one after the other, bear against one another and are made of a pyrotechnic material, and whose external dimensions match the internal dimensions of the relay tube (10) and whose internal dimensions form a common inner ignition channel (19), characterized in that the firing charge rings (14) together forming the firing charge have, at their gable ends directed towards each other, distancing members (16) which define ignition gaps between them.
