Propellant cartridges are used in dynamic devices in which something is moved by means of gas pressure. These are mainly blank cartridges whereby the case of the propellant tank, the powder charge and the primer charge or primer cap is the igniter. The propellant charge is converted into gas in order to move a pin within a pressured chamber. The pin in turn moves or activates another part. In addition to the described cartridges for direct fastening or animal stunning there are also special cartridges for activating ejection seats or defusing explosives. In all applications RUAG Ammotec works closely with system manufacturers and with its pyrotechnical know-how is able to meet varied requirements.
