Definitions

  • the invention relates to a cartridge with an electrothermal igniter.
  • NENA N- (2-nitroxy) -nitramineethane
  • DNDA Dinitro-Diaza-Alkane
  • the invention lies The task is to specify a cartridge in which propellant powder, which is difficult to ignite, especially NENA or DNDA propellant powder, quickly and safely are ignitable, the need for electrical energy should be as low as possible.
  • the invention is based on the idea of transparent propellant powder tubes to use.
  • Nitrocellulose powder in particular has proven to be a propellant charge powder proven to be suitable, in particular that known under the name JA2 Propellant powder. So that this propellant powder is transparent, it must not Contain soot and the usual graphitization of the outer surface must be omitted.
  • the of the Plasma channels emit radiation without large absorption losses to build up the propellant charge the cartridge.
  • the plasma radiation produces a change in the erosion-effective surface of the transparent propellant powder tubes leading to a much faster implementation of the tubes and thus to support the ignition process leads.
  • the exploitation of these properties has a significant reduction the electrical energy requirements of the plasma ignition system.
  • Fig. 1 is a large-caliber cartridge (e.g. for firing from an armored weapon) referred to, which is connected to a current source 3 for ignition via a switch 2.
  • the corresponding weapon in which the cartridge 1 is located has been used for reasons of clarity not shown.
  • the cartridge 1 comprises a combustible filled with NENA or DNDA propellant powder 4 Sleeve 5 and a bottom of the propellant charge sleeve 5 made of metal existing sleeve bottom 6.
  • the combustible sleeve 5 is in the region of its sleeve bottom End 7 positively between an insulating molded part 8 and the sleeve bottom 6 fixed.
  • a high-voltage electrode which is electrically insulated from it 9 arranged, which passed through the molded insulating part 8 and with a metal disk 10 acting as a current distributor is connected.
  • three electrically conductive wires 11-13 are attached, each axially through a tube 14-16 made of transparent JA2 propellant powder (Fig.2) and in the area of the sleeve cover 17 of the propellant charge sleeve 5 with an annular contact part 18 are connected.
  • the contact part 18 contacts in turn the inner wall of the weapon, not shown, which is at ground potential.
  • the transparent propellant powder tubes 14-16 are of several lengths and lengths Provided circumferentially distributed radial openings 19.
  • the charge build-up can be used as a bulk load as well as a stacked or compact load be carried out.
  • the switch 2 is closed and the one with a row energy source equipped with charged capacitors (at a voltage of e.g. 40 discharged within a short time.
  • the discharge current that occurs leads to electrical Explosion of wires 11-13 and initiation of arcing within propellant powder tubes 14-16.
  • the tubes are ignited by the arcs and implemented suddenly.
  • the resulting propellant gases and the released arc radiation then causes a quick and even ignition of the propellant powder 4 located in the sleeve, which together with the combustible sleeve 5 is then implemented.
  • Such temperature compensation using electrical energy can be used of a temperature-independent DNDA propellant powder. Hereby the amount of electrical energy to be provided for the plasma ignition system is reduced.
