Repeatable plasma generator and a method therefor

Abstract

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 () containing a combustion chamber substance (), wherein the filling gas in the combustion chamber duct () is ionized by the high-voltage potential applied to the ionizing electrode (), which is connected to a first high-voltage generator (), thus increasing the electrical conduction capacity in the combustion chamber duct () such that an electrical sparkover through electrical discharge via a second high-voltage generator () between a rear electrode () and a front electrode () is generated and produces an effect, with subsequent ionization of the surface of the combustion chamber substance (), which causes hot gas in a plasma-like state to be expelled from the combustion chamber duct (). The invention also concerns a plasma generator therefor, and an ammunition unit containing said plasma generator.
