Abstract
A plasma generator is provided for initiation of propellant charges in a weapons system, for example when launching projectiles from a barrel weapon, by electrical discharge between a rear electrode and a front electrode in a combustion chamber channel enclosed in a combustion chamber body and filled with filling gas, designed to ignite at least one propellant charge. An ammunition unit and a launching device including the plasma generator are also provided.

A plasma generator for initiation of propellant charges in a weapons system by electrical discharge between a rear electrode and a front electrode in a combustion chamber channel enclosed in a combustion chamber body and filled with filling gas, designed to ignite at least one propellant charge, wherein the plasma generator comprises at least one ionization electrode situated inside the enclosing combustion chamber body, not in physical contact with the combustion chamber body, where ionization electrodes are connected to an initiation circuit, comprising at least one first high-voltage generator, for ionization of the filling gas in the combustion chamber channel, and a second high-voltage generator designed for electrical discharge in the electrically conductive gas from the rear electrode via the at least one ionization electrode onward to the front electrode so that hot ignition gas under high pressure is formed.
