摘要： The invention concerns a method for repeatable ignition of propellant charges in a weapon system, e.g. for firing shells from a barrel weapon, through electrical discharge in a combustion chamber duct (3) containing a combustion chamber substance (30), wherein the filling gas in the combustion chamber duct (3) is ionized by the high-voltage potential applied to the ionizing electrode (7), which is connected to a first high-voltage generator (2), thus increasing the electrical conduction capacity in the combustion chamber duct (3) such that an electrical sparkover through electrical discharge via a second high-voltage generator (5) between a rear electrode (22) and a front electrode (21) is generated and produces an effect, with subsequent ionization of the surface of the combustion chamber substance (30), which causes hot gas in a plasma-like state to be expelled from the combustion chamber duct (3). The invention also concerns a plasma generator therefor, and an ammunition unit containing said plasma generator.

摘要： The invention relates to a method for the repeatable initiation of propellent charges in a weapon system, for example in the firing of projectiles from a barrel weapon, through electrical discharge between a rear electrode (22) and a front electrode (21) in a combustion chamber channel (3) filled with filler gas and comprising a combustion chamber combustion element (30), in which the filler gas in the combustion chamber channel (3) is ionized via a high-voltage potential from at least one ionizing electrode (100, 101, 102, 103), which ionization increases the electrical conductivity in the combustion chamber channel (3) so that an electrical flashover, through electrical discharge via a high-voltage generator (5) between the rear electrode (22) and the front electrode (21), is generated from the rear electrode (22) via at least one ionizing electrode (100, 101, 102, 103) onward to the front electrode (21), which results in hot ignition gas with plasma-like state being expelled from the combustion chamber channel (3). The invention also relates to a plasma generator for the said method, and to an ammunition unit comprising the said plasma generator.
