Definitions

  • the invention relates to an ejection device for grenade launcher or mortar projectiles for simulating a shot, with a propellant charge used in a separate chamber in the projectile body.
  • DE 30 33 061 A1 discloses a grenade launcher training projectile which is provided with a head part and a tail part and with a propellant charge in the tail part and with a smoke-generating signal charge arranged in front of the latter.
  • the propellant charge on this training projectile is located in a separate chamber which is inserted into the rear end of the tail part.
  • the aim of this training projectile is to have its handling largely coincide with a corresponding sharp projectile and to enable good impact marking in the target area despite the lack of explosive effect on impact.
  • the marker charge is therefore filled separately from the propellant charge in the tail tube of the practice floor. The simulation of a shot from a mortar in the smallest space is not possible with this practice floor.
  • the head part of this practice projectile has an internal gas passage with openings for the entry of the propellant gases. Further holes are provided for the exit of the propellant gases, whereby when this training projectile is fired, the resultant propellant gases are directed forward through the inlet openings along the inner passage and out of the outlet openings.
  • the inlet openings can be closed by plugs, as a result of which different cross-sectional areas arise between the inlet openings and the outlet openings. By opening or closing such entry openings, the shooting range of such a practice grenade can be varied from 250 meters to 600 meters. So this practice floor is also not suitable for shooting simulation in the smallest space and in assembly halls.
  • the ejection speed of the piston used according to the invention which is driven by the powder gases of the blank cartridge used, is always the same. This means that the same throw distances can always be achieved. Drain openings are also provided at the end of the piston acceleration path, so that when the ejection device is removed from a mortar cartridge that has been fired, there is no pressure on the piston.
  • the piston Due to the falling energy of the mortar projectile when striking the base in the mortar weapon barrel, the piston is struck against the fixed firing pin in the ejection device, whereby the blank cartridge stored in the piston is ignited. The powder gases released thereby drive the piston against its annular stop in the hollow cylinder at high speed. The piston pushes off the base of the mortar weapon barrel and thus throws the practice projectile out of the barrel only a few meters.
  • the grenade launcher or mortar projectile 1 be consists of a head part 2 and a tail part 3 with stabilizing wings 4.
  • a blind bore 5 is made from the rear side, which receives the ejection device 6.
  • the ejection device 6 for the mortar projectile 1 for simulating a shot consists of a hollow cylinder 7 which is screwed into the tail part 3 against a stop 9 by means of a thread 8.
  • the hollow cylinder 7 On its end face 10 facing the head part 2, the hollow cylinder 7 is closed by a base piece 11 with a centrally inserted firing pin 12.
  • This blind bore is located on the longitudinal axis 16 of the projectile body.
  • a blank cartridge 17 is inserted into the blind bore 15 .
  • the rear end of the piston 13 facing the base piece 11 has an enlarged diameter with an axial annular surface 18.
  • the piston 13 is provided with a radial blind bore 19.
  • a locking pin 20 is inserted, the bottom surface 21 of which has an opening 22 into which a spring 23 engages, which is supported on the bottom 24 of the blind bore 19.
  • the locking pin 20 engages in a corresponding locking groove or notch 25 in the inner wall 26 of the hollow cylinder 7.
  • a substantially parallel to the longitudinal axis 16 of the cross bore 27 in the locking pin 20 receives a locking pin 28 which is supported in a corresponding bore 29 in the piston 13.
  • a pull ring 30 is located on the securing pin 28 at the rear end of the ejection device 6.
  • the axial movement of the locking pin 20 in the blind bore 19 is limited by a pin 31 which is firmly inserted in the pin 13 and engages in an edge recess 32 of the locking pin 20.
  • the hollow cylinder 7 has gas discharge openings 33 in its front region, which are located at the end of the acceleration path of the piston 13 during a movement in the direction of the arrow 34. Because of these gas discharge openings 33, the piston 13 is without pressure when the ejection device 6 is removed from the mortar projectile 1.
  • the hollow cylinder 7 is provided with a reduced diameter in the region of the projectile end, as a result of which an axial annular surface 35 forms on the hollow cylinder 7, which faces the annular surface 18 of the piston. These two ring surfaces 18 and 35 form an end stop when the piston 13 moves within the hollow cylinder 7 in the direction of the arrow 34.
  • a further radial blind bore 36 is provided in the piston 13.
  • the shot simulation with the mortar projectile takes place in that the mortar projectile 1 is inserted into a weapon barrel of a mortar, not shown here, from the weapon barrel mouth. Due to the falling energy of the mortar projectile 1 when it strikes the bottom of the mortar tube, the piston 13 is now struck against the fixed firing pin 12 in the bottom part 11 of the ejection device 6, as a result of which the blank cartridge 17 stored in the piston 13 is ignited.
  • the now released powder propellant gases drive the piston 13 at high speed against its stop 18 and 35 in the hollow cylinder 7.
  • the piston 13 is consequently driven out of the rear end of the projectile and pushes off the base of the weapon barrel in the mortar and throws the mortar projectile 1 together with the ejection device 6 from the barrel of the mortar.
  • the range of the mortar projectile 1 thrown out in this way is only a few meters after leaving the weapon barrel, so that this device is suitable for carrying out a simulation of mortars and mortar projectiles in a hall or in very small spaces.
  • the piston 13 is held in its storage or transport position according to FIG. 2 in the cylinder by the locking pin 20. Only after pulling out the locking pin 28 via the ring 30 is it possible to move the locking pin 20 within the blind bore 19 against the action of the spring 23. The energy released when the blank cartridge 17 is ignited is sufficient to push the locking pin 20 out of the locking notch 25 against the stop pin 31 when the piston 13 moves in the direction of the arrow 34.
