Propellant cartridges are used in dynamic devices in which something is moved by means of gas pressure. Principally they are blank cartridges, in which the propellant charge is converted into gas and further on into kinetic energy. The butt in its turn moves or activates another part. In addition to the described cartridges for direct mounting or animal stunning there are also special cartridges for actuating ejection seats or defusing explosives. In all spheres of their application RUAG Ammotec closely cooperates with system manufacturers and its know-how in the sphere of pyrotechnics helps to meet the most exacting requirements.
