Abstract

The present invention relates to a propellant charge module for artillery guns, of the type which is usually referred to by the term "modular charges" (1). A special feature of this type is that, in an otherwise empty pyrophoric relay tube (10) arranged axially in the longitudinal direction of the charge, it has a firing charge which is made up of a plurality of successive powder rings (14), the different ring-shaped parts of this firing charge having distancing members (16) which are directed towards each other and give rise to narrow ignition gaps (18) between them.
