14.5x51mm Sub-Calibre Ammunition for Artillery Training Systems with Impact Fuze
The 14.5x51mm sub-calible ammunition can be used in all types of 14.5×55 artillery training systems (ATS) with riffled barrels of 14.5mm calibre.
Projectile Construction
Inside the intermediate steel casing there are :
– The igniter case (13) containing the elements of the impact fuze.
– The smoke composition case (14) containing the smoke composition (15).
The base of the projectile is covered with a plastic base cap(16).
The impact fuze consists of the igniter case (13) with the firing pin (7) revetted into its head, the safety spring (8) and the firing bolt (12) with safety casing (9), igniter (10), booster (11) and the paper plate. The individual elements are joined together by crimping of the igniter case.
Functional Description
When the firing pin strikes the priming cap, the primer ignites the propellant composition. The gas pressure of the propellant composition forces the projectile out of the barrel. Owing to this impulse the safety casing slides backwards on the firing bolt thus arming the igniter. So only the safety spring sits between firing bolt and firing pin .
When the projectile impacts in the target area the safety spring is pressed together and the firing bolt strikes the firing pin with the igniter. The igniter together with the booster ignites the smoke composition, which is ejected through the back end of the projectile. This entire action results in an audible report, a flash to be seen from afare and a light grey smoke cloud. As the projectile does not contain any explosive charge there is no fragmentation when the projectile impacts.
