Definitions

  • Armor-piercing weapons have become known in which a projectile, for example with a hollow charge, is located in a weapon barrel which is open on both sides and is equipped with a firing mechanism. After firing, the projectile with rocket drive leaves the tube, which is used for setting the firing range and direction, practically without recoil, and fire from the propellant charge also emerges from the tube at its rear end. Flashes of light, smoke and a bang can easily draw an enemy's attention to the launch site.
  • the object of the present invention is now to create a weapon with a projectile, in particular an armor-piercing infantry weapon, which, based on its recoil forces when the countermass brakes when firing, has the shortest possible transport length, reduces the risk to the crew as a result of the high gas pressures in the weapon barrel and in the launch signature and the like are reduced to a minimum.
  • a simple production method, in particular by pulling or flow pressing, the hollow cylinder of the telescope system is achieved if in the region of the ends of the hollow cylinder and the displaceable wall element, mutually cooperating stops are designed in the shape of a truncated cone.
  • the projectile 2 with head 20 with, for example, armor-piercing ammunition, furthermore with tubular shaft 21 and stabilizing fins 22 displaceable on the shaft is arranged in weapon barrel 1.
  • Shaft 21 projects into an inner tube 31, which is telescopically mounted in an outer tube 30 of a tube system 3.
  • a wall element 310 which has a stop 310 'for shaft 21 of floor 2 and is convexly curved towards warhead 20, is slidably mounted.
  • the outer tube 30 is closed at its rear end by a wall element 300 which is convexly curved toward the rear of the weapon barrel 1, for example approximately hemispherical.
  • the outer tube 30 itself is embedded in a mass 6 arranged in the weapon barrel 1, for example a fibrous material weighted paper, moistened textiles, plastic strips or the like, in particular partial mass 6 'in the area between the rear wall element 300 of the outer tube 30 and back end of the gun barrel 1 for braking and partial absorption of the recoil forces. If, for example, a current surge flows through induction in line 7, the propellant charge 5 'is ignited in the previously defined space 4 within the telescopic tube system 3.
  • the fin part 22, which is displaceably mounted on the shaft 21 of floor 2 - for example made of extruded profile - is practically in contact with the warhead 20 and lies on the back, for example, on a holder 51 in the gun barrel 1 for flexible elements 5, for example bands which are connected to the Outer tube 30 of the telescopic tube system 3 are connected to its holder, or on end faces and stops 305, 315 of the tubes 30, 31 of the tube system 3 pushed together in this state.
  • An advantage of the weapon in addition to its simple construction, is that after the projectile 2 has been fired, the propellant gas is still essentially held in an expanded space 4, which is defined in its final dimension by the telescopically displaceable tubes 30, 31 and their wall-limiting elements 300, 310, and if necessary flows slowly and without leaving a signature.
  • This can be an essentially floor bang and flash of light u. The like. Avoid firing the projectiles.
  • the safety of the crew is significantly increased by the double jacket consisting of weapon barrel 1 and telescopic barrel system 3 and by avoiding a recoil fire jet when firing.
  • the counter mass 6, e.g. fibrous mass only emerges from the rear of the weapon barrel at low speed and its energy is effectively reduced by swirling.
  • the new weapon is characterized by the shortening of the overall length that can be achieved as a result of the telescopically expandable propellant gas discharge space 4.
  • the anti-tank pipe according to FIG. 2 has essentially the same components as the pipe according to FIG. 1 and for this reason analog parts are designated with the same reference numerals used in FIG. 1.
  • the stops 305, 315, 316 of the tubes 30, 31 and 310 'of the converting element 310 of the inner tube are designed differently. They are essentially of the shape of a truncated pyramid (with a tip towards the mouth side), which in particular facilitates and reduces the cost of production during flow pressing.
  • the outer tube 30 is stabilized and guided by means of a substantially axially extending guide rail 9 penetrating its rear wall element 300.
  • An electrically ignitable capsule 73 for igniting the propellant charge 5 can also be attached to this guide.
  • the inner truncated cone surface of the stop 316 of the inner tube 31 pointing towards the space 4 with the propellant charge 5 can be used to delay the effect of the propellant charge pressure on it and thus a possible premature pushing out of the inner tube 31 before pushing out the projectile 2 by means of wall element 310 with stop 310 '' to be covered by cover plates 308.
  • plug-like closures 107, 108 can be provided on both ends of the weapon barrel 1 for transport.
  • FIG. 3 shows how on a weapon barrel 1, in which the part 6 'of the countermass is visible at the open rear end, on the outside of which holders 101, 102 are arranged, into which a conventional assault rifle 8 with piston 82 and integrated sighting device 83 can be used.
  • the muzzle device 84 on the barrel 85 is located in a receptacle of the coil housing 72 with an induction coil (not shown), with which the propellant charge located inside the previously described telescopic tube system can be ignited via lines.
  • the projectile flying through a coil in the coil housing 72 triggers an induction current by means of which the propellant charge is ignited in the weapon barrel 1.
  • This preferred type of ignition has the advantage over other - also inductive - ignitions that no separate trigger mechanism has to be provided on the weapon barrel, moreover the alignment of the barrel is facilitated and thus the accuracy is increased.
