Claims
- 1. 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.
- 2. The cartridge according to claim 1 including a plurality of tubes and a plurality of said electrically conductive wires extending through respective ones of said tubes and connected between said high voltage electrode and said contact.
- 3. The cartridge according to claim 1 wherein the contact is an annular contact extending around the sleeve.
- 4. The cartridge according to claim 1, wherein the second propellant-charge powder is nitrocellulose powder.
- 5. The cartridge according to claim 4, wherein the second propellant-charge powder is JA2 propellant-charge powder.
- 6. The cartridge according to claim 1 wherein the first propellant-charge powder is N (2-nitroxy)-nitraminethane propellant-charge powder.
- 7. The cartridge according to claim 1 wherein the first propellant-charge powder is dinitro-diaza-alkanes propellant-charge powder.
- 8. The cartridge according to claim 1 wherein the tube formed of the second propellant-charge powder is provided with a plurality of radial openings that are distributed over the tube length and circumference.
- 9. The cartridge according to claim 2 wherein at least three of said tubes extend axially through the first propellant-charge powder located in the sleeve, with each said tube having a respective one of said conductive wires extending there through and connected between said high-voltage electrode facing the interior of the sleeve, and to which the wires are connected, is formed as a current distributor.
- 10. The cartridge according to claim 9, wherein the current distributor is a metal disk.
