Abstract
A method is provided for an electric activation of a plasma jet igniter for firing Electro-Thermal-Chemical (ETC) guns, machine guns and other equivalent ETC barreled weapons, without complete consumption of any of the components necessary for its activation upon activating the igniter. Each activation of the igniter by means of one or several voltage pulses, which from an electric pulse generator (10) are conducted between an anode (4) and a cathode (5), is preceded by heating of the anode (4) to such high temperature that at least parts of the dielectric material (2) arranged in proximity to the anode (4) have begun to vaporize. The method may be implemented using an adapted plasma let igniter which has an anode that can be heated to a high temperature so that the igniter can be used for firing whole series of rounds or a full magazine of successively fired rounds in rapid order.
