Definitions

  • the invention relates to a disk-shaped propellant charge module for a Layered propellant that can be assembled from several such modules.
  • An increase in the performance of large-caliber tank cannons usually requires an increase the charge density of the propellant powder. With the increase in loading density, homogeneous ignition of the entire charge is becoming increasingly problematic because the free spaces left in the cargo for the flame to spread or are called Plasmas are too low. A non-homogeneous ignition, on the other hand, can lead to the formation of cause asymmetrical pressure waves in the cargo area, which can destroy the weapon.
  • a ring tablet for gas generators which in particular is used for air bag generators.
  • the respective tablet has a central axial ignition channel, from which radial ignition channels to the tablet edge arranged on the top and bottom of the tablet extend there.
  • the invention has for its object to provide a propellant charge module of the type mentioned, which ensures a uniform and symmetrical ignition of the propellant charge of a cartridge with an increased charge density (> 1.2 g / cm 3 ).
  • the invention is based essentially on the idea of having the propellant charge module at least three, preferably six, evenly distributed on a circle axial Ignition channels and at least three, preferably also six, in the interior of the Propellant charge modules to radial ignition channels extending up to its outer surface provided, each of the radial ignition channels at least one of the axial ignition channels cuts.
  • the individual Propellant charge modules are stacked in the corresponding cartridge so that their axial Ignition channels form a continuous ignition channel.
  • the radial ignition channels provide for a better spread of the flame or the plasma (with a plasma ignition) in the entire cargo space.
  • the radial ignition channels provide possible predetermined breaking points of the powder disks. These predetermined breaking points enable a jam-free Passage of the cargo through the transition area from the cargo area to the gun barrel, because the radial ignition channels provide a defined structure for the corresponding powder fragments is achieved.
  • the propellant charge modules are each corrugated Have surface so that in the finished propellant charge between adjacent modules still a small distance for the lateral spread of the flames in the entire cargo space remains.
  • the use of multi-perforated has been used to increase the progressivity of the burn Powder disks proved to be useful, the number of perforations, each according to the desired progressiveness or wall thickness of the propellant charge modules, between approx. 1000 and about 4000 should be.
  • the perforations can occur when extruding the powder or introduced through holes in a CNC machine.
  • FIG. 1 denotes a cartridge which has a propellant charge sleeve filled with a propellant charge 2 3 and a sabot projectile 4 with protruding into the propellant charge sleeve 3
  • Bullet tail 5 includes.
  • the propellant charge 2 essentially consists of a large number side by side stacked, disc-shaped propellant charge modules 6 together.
  • the propellant charge modules 6 each have a central one Recess 7 in which loose bulk powder 8 is additionally introduced.
  • the individual propellant charge modules 6 are adapted to the propellant charge sleeve 3 and have e.g. an outer diameter of approx. 150 mm and a width of 5 to 20 mm. she each have six evenly symmetrical to the central axis 100 of the Propellant charge modules 6 lying circle arranged axial ignition channels 9 (Fig.2) and six radial ignition channels 10 located in the interior of the propellant charge module 6 (FIG. 3) on, which extend to the outer surface 11 of the respective propellant charge module 6. Each radial ignition channel 10 intersects two axial ignition channels 9.
  • the propellant charge modules 6 are stacked in the propellant charge sleeve 3 such that the axial ignition channels 9 form a continuous ignition channel 12 (Fig.1).
  • the radial ignition channels 10 serve both for better flame front broadening and to ignite the powder disks 6 from the inside and as predetermined breaking points to defined Generate fragments that provide a traffic-free passage from the cargo space of the corresponding Allow weapon into the weapon barrel.
  • the outer surface 11 of the propellant charge modules 6 is slightly corrugated, so that between adjacent propellant charge modules 6, a gap-shaped space remains which after ignition of the propellant charge 2 does not expand laterally shown igniter coming flames can take place.
  • Propellant charge modules 6 around multi-perforated powder disks, e.g. 3000 perforations 13 (FIG. 4) are present per propellant charge module 6.
