Definitions

  • the invention relates to a projectile with a cartridge, wherein a passage opening of the cartridge base contains a squib which can be fired from the outside and which ignites a damaged propellant charge provided in the interior of the cartridge in a propellant charge cartridge, and the propellant charge cartridge, the diameter of which is smaller than that of the projectile, has at least one has lateral gas outlet opening in a gas pressure chamber of the cartridge.
  • Such projectiles are known for example from AT-B 371 596 and AT-B 374 583.
  • the propellant charge cartridge is screwed into an opening in the base of the cartridge and the propellant charge covered by the squib to the outside.
  • several gas outlet openings open out laterally from the propellant charge cartridge.
  • the struck detonator ignites the damn propellant charge, the gases of which escape into the gas pressure chamber, so that the bullet is released from the cartridge after a corresponding pressure has been built up. Since the gas outlet openings are removed from the burning side of the propellant charge bordering the squib, the overflowing gases entrain propellant charge particles, which thereby escape combustion.
  • the portion that is clearly visible in the cartridge after firing is relatively large. Experiments have shown that fluctuations of 15% or more can result in the launch speed, which significantly impair the target safety.
  • the propellant cartridge diameter corresponds to that of the projectile, so that a propellant charge of maximum size can be accommodated.
  • the gas outlet openings are provided in the base of the propellant charge cartridge, which open into a comparatively small gas pressure space between the base of the propellant charge cartridge and the cartridge base. The rocket propulsion eliminates the need for a constant launch speed.
  • the invention has now set itself the task of creating a projectile of the type mentioned, which is easier to manufacture, and in which a largely constant initial speed is achieved by as complete a combustion of the propellant charge and the target safety is improved.
  • the propellant charge cartridge is connected to the projectile and has a cartridge bottom which effects the insulation of the propellant charge, which touches the cartridge bottom and is provided with an ignition opening coaxial with the passage opening in the cartridge bottom.
  • the arrangement of the propellant charge cartridge on the floor significantly simplifies the manufacture of the cartridge, since these, including their very small passage opening, can be produced in a single non-cutting operation, for example by deep drawing, while the manufacture of the floor or its base part is only insignificantly complicated.
  • the pot-shaped propellant charge cartridge in particular screwed into a protruding threaded connector of the base part, preferably contains a cover which covers the ignition opening and which can be destroyed by the ignition jet of the squib. At least the area of the cartridge base surrounding the ignition opening touches the cartridge base in the area surrounding the passage opening, a small gap being present only because of production inaccuracies, so that the propellant gases are prevented from escaping through the ignition opening. Since the propellant charge burns off from the ignition opening, there is initially a strong insulation until the firing cross-section has reached the lateral gas outlet openings, which are preferably arranged near the base of the cartridge in the peripheral wall of the propellant charge cartridge.
  • a projectile of any kind such as an explosive grenade with a delay detonator or impact detonator, a smoke grenade, a practice projectile, etc. is inserted into a cartridge 3, a gas pressure chamber 10 being formed between the base part 2 of the projectile and the cartridge base 4.
  • the floor 1 is or the like with a circumferential groove 11. to form a positive connection with an edge region 12 of the cartridge 3, which, as shown, is achieved by crimping the edge 12 or by means of embossments distributed over the circumference or by means of an annular bead.
  • the cartridge 3 is deep-drawn, for example, from an aluminum alloy, and has a central passage opening 5 in an area 16 of the cartridge base 4, into which a squib 9 is inserted.
  • a threaded connector 13 is formed, in which a propellant charge cartridge 6 is inserted, which contains the propellant charge 7.
  • the propellant charge cartridge in the cartridge base 17 has a central ignition opening 15 of small diameter and lateral gas outlet openings 8, which are provided on the inside by a cover 14 made of easily destructible material, such as paper, plastic or the like. are closed to prevent the propellant charge 7 from falling out the.
  • the cartridge base 17 touches the cartridge base 4, or at most has a small distance from it that results from production inaccuracies.
  • the ignition jet of the squib 9 acted upon from the outside hits the propellant charge 7 through the openings 5 and 15, the cover 14 being destroyed.
  • the propellant charge 7 is thus ignited at the ignition opening 15, and because of the contact or the very small gap between the cartridge base 17 and the area 16 of the cartridge base 4, there is initially a high degree of insulation.
  • the developing propellant gases then exit through the lateral gas outlet openings 8 arranged near the cartridge base 17 into the gas pressure chamber 10. Propellant particles entrained by the propellant gases from the interior of the propellant charge cartridge 8 must thereby pass through the firing cross-section which extends from the ignition opening 15 so that their complete combustion is ensured.
  • the initial speed given to a projectile 1 according to the invention after the interlock 11, 12 breaks is therefore subject to only slight fluctuations, since an approximately constant gas pressure can be achieved, and the target reliability is significantly improved.
