Definitions

  • the invention relates to a device for delayed ignition for electrically operated Ammunition, in particular dummy ammunition with pyrotechnic, pyrophoric or hypergolic active masses.
  • flares pyrotechnic infrared emitters
  • These flare ammunitions generally consist of a cartridge case with an electrical igniter and the pyrotechnic active mass. Cartridges for mock ammunition are available in many calibers. There are cylindrical ammunitions in calibers 26.5, 36, 38, 40 and 55 mm. There are also ammunitions with a rectangular cross-section in calibers 25x25, 25x52 and 52x65 mm. Sets of active ingredients based on magnesium / Teflon / Viton or based on red phosphorus are frequently used, and pyrophoric and hypergolic active compositions are also known. Characteristic of all flare active materials is the intense heat and flame formation that occurs during combustion.
  • pipe fuses For such premature burning of the active mass in the launcher to prevent, so-called pipe fuses are used. These facilities make sure that the active mass only outside the launcher is lit.
  • Examples of such pipe fuses are e.g. Sliding locks such as e.g. in US 5,561,259.
  • the principle of these fuses is based on the fact that a pyrotechnic delay element due to the combustion of the propellant charge (VZ element) is initiated in a sabot. Get the sabot outside the sleeve, the ignition channel is between by means of spring force VZ element and active mass-side firing released and it takes place Ignition of the active mass. For example, if the propellant charge were too weak and the active mass and especially the sabot was still in the sleeve, so the ignition channel between the ignited VZ element would remain closed, and there would be no triggering of the active mass.
  • Another form of pipe protection provides that a mechanical safety device, a so-called g-safety device in a sabot element, is overridden by the launch acceleration. If this sabot is now outside the cartridge case, a lock is lifted by spring force, similar to that described above, and a firing pin is triggered, which initiates the active mass via a primer.
  • a mechanical safety device a so-called g-safety device in a sabot element
  • a particular disadvantage of the latter tube safety device is the risk of unintentional triggering when such ammunition is dismantled. Only a small acceleration load is sufficient to override the g-safety device and to unlock the firing pin for triggering the primer, which causes the active mass to be released after the active substance body has been removed from the cartridge case.
  • a pipe protection that has been known for a long time and is in use works via a friction element.
  • a propellant charge is used to Active mass body pushed out of the sleeve via the sabot.
  • a sub-caliber taper ensures that the sabot is held.
  • the active mass moves due to the Acceleration continues and separates from the sabot.
  • One at the sabot fixed friction wire is therefore by a friction primer integrated in the active mass pulled and triggers the active mass (decoy flare MJU-8A / B).
  • the object of the present invention is to eliminate these disadvantages.
  • a pipe fuse for electrically actuated pyrotechnic Ammunition presented the problems in dealing with friction sets prevented and in which no inert parts after the ejection of the active mass body be expelled.
  • the ammunition according to the invention consists, as shown in FIG. 1 , of a cartridge case 10 with an inserted electric lighter 1, sabot 4 and active mass 8
  • the electrical lighter (Squib) 1 with the contact pins 1a and 1b and the Bridge wire 1c is galvanically 5 via a suitable electronic circuit 1d connected to a capacitor element 3 which is located in the sabot 4 located.
  • the capacitor element 3 in the sabot 4 is also galvanic 6, with a mechanical switching element 7 connected in the active mass 8.
  • This switching element 7 is in turn galvanically 7a with an electrical igniter 9 in the Active mass 8 connected.
  • the electrical ignition pulse triggers the propellant charge 2 over the bridge wire 1c in the squib and the charging of the capacitor element 3 in the sabot 4. Due to the gas pressure of the propellant 2 the sabot becomes 4 with the charged capacitor element 3 and the one in front Active mass 8 moved through the sleeve 10.
  • the galvanic connection between sabot 4 and Squib 1 are either interrupted or exist stay.
  • At the sleeve opening 11a causes a sub-caliber ring 11b that the sabot 4 is held.
  • the active mass 8 moves due to the acceleration continues and separates from the sabot 4.
