ABSTRACT:
The pyrotechnic igniter comprises a strong outer casing (3) whose bottom is equipped with divergent peripheral openings (4) and an ignition charge (5) placed in this casing. In order to obtain reproducible thermodynamic characteristics during the firing of the gas-generating charge (1) with a central channel, while withstanding the very high accelerations produced when the gun is fired, the inner surface of the casing comprises a means of axial positioning of the charge which provides a free space (6) between the downstream face of the charge and the bottom of the casing, the ignition charge (5) comprising a peripheral sleeve (7) resting on the said means of axial positioning.
