Definitions

  • the invention relates to a pyrotechnic self-dismantling device for projectiles, rockets, bomblets and mines according to the preamble of claim 1.
  • a pyrotechnic self-dismantling device for projectiles, missiles, bomblets and mines is known from EP-A-0 256 320. It has an ignition device for a pyrotechnic delay device in a housing.
  • the delay device is arranged in a slide which is mounted so that it can move transversely in the housing, this slide being extendable via a lateral opening on the housing via the outer housing contour.
  • the delay device consists of an ignition charge, a delay charge and a detonator for igniting an explosive charge.
  • the detonator can be triggered by a firing pin that can be actuated when the ammunition strikes.
  • a firing needle which is biased by a spring, is mounted in the slide to ignite the deceleration rate. If the delay set is fired outside of the rule, the detonator is inevitably initiated. There is a risk that the explosive charge will be detonated. However, this risk should be excluded.
  • the invention is based on the object of proposing a pyrotechnic self-dismantling device in which it is ensured that a delay block ignited outside the rule in safety does not initiate the detonator provided for detonating the explosive charge.
  • a firing pin 15 engages securely in a bore 16 of the slide 8.
  • a detonator 17 and a sheet 18 with an ignition needle 19 are crimped in the slide 8.
  • a delay detonator 25 has: A tube 26 with the sections 27 and 28, an ignition set 29, a delay set 30 and a transmission set 31. 2, the latter lies outside the response range 32 of the detonator 17.
  • the tube 26 is slidably mounted in a slide guide 34.
  • a ball 35 is mounted in an opening 36 of the slide 8 while the slide 8 is secured.
  • the ball 35 is supported on the slide guide 34 and rests on a shoulder 37 of the delay detonator 25.
  • the opening 36 is outside the housing 4.
  • the slide 8 is provided with a spring 40.
  • the slide 8 has a center of gravity 9 at a distance 10 from the main axis 11.
  • the bomblet 1 ejected from a swirl projectile also has a corresponding swirl.
  • a stabilizing parachute lifts the firing pin 15 out of the bore 16 in a known manner. Then the centrifugal forces generated by the swirl and acting on the slide 8, supported by the spring 40, move the slide 8 into the focus shown in FIG. 3.
  • the opening 36 lies outside the jacket 6, the ball 35 is thrown out of the opening 36 and has thus released the delay detonator 25. This strikes against the sheet 18 due to the inertial forces, whereby the firing needle 19 initiates the ignition charge 29.
  • the slide 8 initially only transports the delay detonator 25 until the stop 21 hits the stop 20 of the housing 4 in its movement phase. The delay detonator 25 is unlocked.
  • the inertial forces act solely on the delay detonator 25 and move it up to the sheet metal 18.
  • the transmission set 31 immediately adjacent to the detonator 17 ignites the detonator 17 in accordance with the arrow 44. This then initiates the explosive charge 3 via the transfer charge 2.
  • the slide 8 is secured in a known manner.
  • the telescopability of the delay detonator allows a relatively large overall length, which is only limited by the run-up section 50 between the firing needle 19 and the primer. In addition, there is also a safety distance, which is defined as the response area 32. Therefore, if the delay detonator 25 is fired in a safe manner outside the rule, it is ensured that the detonator 17 is not initiated due to the spatial separation.
  • the hot gases and particles of the transmission set 31 are discharged into relaxation rooms (not shown) of the pyrotechnic igniter 5. Despite the fact that the delay detonator 25 can be telescoped, it is ensured in the focus that the transmission set 31 is in the immediate vicinity of the detonator 17.
  • the transmission set 31 penetrates the section 28, the wall 33 and the detonator cup 38.
  • a spring 12 effects or supports the setting of the delay detonator 25.
