Abstract
A cartridge having an electrothermal ignition device, in which, ignition conduits extend axially through a first propellant-charge powder (4) filling a cartridge sleeve (5), with the conduits essentially comprising an electrical wire (11-13) that is guided axially through a tube (14-16) comprising a second propellant-charge powder. Propellant-charge-powder tubes (14-16) comprising an optically transparent propellant-charge powder are used so that even cartridges (1) having a first propellant-charge powder (4) that is difficult to ignite can be ignited rapidly and reliably, requiring the smallest possible quantity of electrical energy.
Claims10
A cartridge with an electrothermal ignition device comprising:
- a cartridge including a combustible sleeve that is at least partially filled with a first propellant-charge powder, and a metal base connected to one end of the sleeve and forming the base of the cartridge;
- a high-voltage electrode extending through and insulated from the base;
- an electrically-conductive wire, which extends axially through the first propellant-charge powder, having a first end connected to the high-voltage electrode and a second end connected to an electrical contact disposed in a forward region of the combustible sleeve for contact with an inner wall of a gun barrel when the cartridge is fired;
- and,
- a tube formed of a second propellant-charge powder disposed in the first propellant charge powder along at least an axial portion of the combustible sleeve, and through which the electrically-conductive wire is guided axially with the second propellant-charge powder being an optically transparent propellant-charge powder.
