ABSTRACT:
An after-firing safety mechanism of a training ammunition that is fired through the central barrel of a full-caliber dummy projectile is described. The training ammunition includes a primer igniting an active charge upon impingement of the training ammunition on the target, as well as a locking pin ejectable perpendicularly to the axis of the training ammunition, this pin fixing the primer in place at least as long as the training ammunition is within the barrel of the dummy projectile. The locking pin is inserted in this arrangement in a cavity, to be ejectable by gas pressure. The cavity is in communication with a pyrotechnical gas generator; the latter being connected to an ignition system operating with delay. This ignition system is initiated upon firing of the training ammunition from the barrel of the dummy projectile.
