Repeatable plasma generator and a method therefor

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.

1. Plasma generator for repeatable ignition of propellant charges in a weapon system through electrical discharge in a combustion chamber enclosure containing a combustion chamber duct and a combustion chamber substance configured in connection with a combustion charge, wherein the plasma generator contains an ionization electrode connected to a first high-voltage generator for ionization of a filling gas in the combustion chamber duct for producing an electrically conductive gas and a front electrode connected to an electrical ground and a rear electrode electrically connected to a second high-voltage generator configured for electrical discharge in the electrically conductive gas so that hot ignition gas is formed under high pressure.
