A flash guide tube arrangement utilized primarily in propellant charge igniters for large-caliber ammunition with laterally located openings from which the ignition gases, emitted by conventional ignition systems, exit, either for the ignition of an ignition booster charge or for the direct ignition of a propellant charge. Indentations emanate axially from these openings and extend into the interior of the flash guide tube, the depth of the individual indentations decreasing in the direction toward the rear end of the flash guide tube. The indentations are preferably radially arranged and several of such radially disposed indentations can be provided in the flash guide tube. The rear end of the flash guide tube can furthermore be constructed as a cone having its apex pointing toward the ignition system.

Flash guide tube arrangement for propellant charge igniters

A propellant charge igniter includes a casing that contains a central contact member, an igniter element, a sealing element associated with the igniter element, and a powder charge. The sealing element has on a side facing the powder charge, an annular collar in sealing contact with an inner wall of the casing.

Propellant charge igniter

A projectile for training ammunition wherein the projectile body is joined at its front end to a dummy detonator. The dummy detonator is constructed as a hollow body and preferably a cap-shaped hollow body.

Projectile for practice ammunition

A propellant charge igniter has an outer sleeve open at one end, an inner sleeve positioned within the outer sleeve and provided with a closed-end portion adjacent to the one end of said outer sleeve. A closed-end portion of the inner sleeve has predetermined bursting zones and contains a booster propellant charge. The propellant charge igniter is also provided with an expansion ring of a pressure-resistant material of low tensile strength which is arranged adjacent to the one end of the outer sleeve between the outer sleeve and the inner sleeve.

The present invention relates to a propellant charge igniter having a striker element with a rearward cylindrical shank portion extending through the bottom piece of the propellant charge igniter, a forward headpiece following the shank portion and having an enlarged outer diameter with respect to the shank portion, the striker element resting on an annular shoulder formed in the bottom piece and being provided with an annular, separable collar held by means of a counter member extending over the headpiece.
