摘要:
The invention relates to a method of, in the electrical ignition of a propellent charge (1) provided with an electrically conductive surface coating (5) and comprising one or more propellant components (3), ensuring that ignition and progressive combustion of the propellent charge take place. The method is characterized in that said electrically conductive surface coating, when ignition of the propellent charge is desired, is connected to an electrical high-voltage source (6), in that said high-voltage source is made to generate at least one high electrical pulse to said connected electrically conductive surface coating, and in that said at least one high electrical pulse produces an instantaneous flashover ignition of the electrically conductive surface coating of the propellent charge and of all its propellant components, simultaneously. The invention also relates to a propellent charge and to an ammunition shot comprising the propellent charge.

The invention relates to a plasma generator (4, 4′) for electrothermal and electrothermal-chemical weapon systems, which plasma generator comprises a combustion chamber (20) having a combustion chamber channel, and a center electrode (24, 24′) disposed inside the combustion chamber channel (20′), which combustion chamber and center electrode are electrically conductive and each comprise a respective first connector (26, 42′, 33, 45′) for an electrical connection to a respective second connector (14c, 49, 14d, 48), interacting with the respective first connector, on the back piece of the weapon system. The connector (42′) belonging to the combustion chamber and the connector (45′) belonging to the center electrode are axially displaceable relative to each one of the connectors (48, 49) belonging to the back piece (14), with a maintained, radial contact between the first and the second connectors (42′, 45′ and 48, 49). The invention also relates to a method for maintaining the electrical contact of the plasma generator.

The invention relates to a cartridge case (2) and ammunition round (1) primarily for electrothermal and/or electrothermochemical weapon systems, which round comprises the said cartridge case. According to the invention, the casing (10) of the cartridge case comprises or consists of one or more insulated or insulating shells, layers or surfaces (11, 12, 13) for, at least electrically, insulating the casing of the cartridge case from the barrel (14) of the weapon system and also preferably from at least the bottom (16) and/or firing device (5) of the ammunition round as well, but preferably also from the rest of the ammunition round, when the round is used, and also preferably from at least the bottom and/or firing device of the ammunition round as well, but preferably also from the rest of the ammunition round, when the round is stored and handled. The invention also relates to a method for manufacturing an, at least electrically, insulated or insulating cartridge case and an ammunition round primarily for electrothermal and/or electrothermochemical weapon systems, which round comprises such a cartridge case, and also use of such insulated or insulating cartridge cases and ammunition rounds in different weapon systems, but preferably in electrothermal and electrothermochemical weapon systems.

The invention relates to a plasma generator (4) for electrothermal and electrothermal-chemical weapons systems, the plasma generator being intended, via at least one emitted energy pulse, to form a plasma, which is designed to accelerate a projectile (3) along the barrel (11) of the weapons system in question, the plasma generator comprising a combustion chamber (20) having an axial combustion chamber channel (20′) and a ceramic arranged inside the combustion chamber channel for insulating the combustion chamber. According to the invention the ceramic consists of a shrink- fixed, compressively pre-stressed ceramic tube (23). The invention also relates to a method for shrink-fixing the ceramic tube in the combustion chamber channel as well as an ammunition round comprising a plasma generator according to the invention.
摘要:
An electrical energy-insulating, preferably ceramic, insert (15) which is fitted in a barrel (2) is adapted in order to prevent electrical energy transmission (16) from an electric igniter (3) to a barrel body on firing of an ammunition unit (11) which can be initiated with the electric igniter (3). The insert is arranged in a position for firing of the ammunition unit. By means of the invention, a simple solution is obtained to the problem of electrical energy transmission by virtue of the fact that other measures do not have to be taken, for example the cases of the ammunition units do not have to be adapted by complicated and cost-increasing measures.
