Definitions

  • the invention relates to a pyrotechnic detonator for projectiles according to the preamble of claim 1.
  • a detonator and a primer for a housing-fixed, spirally arranged retardation are provided in a transverse slide. It has been recognized that, in the case of spiraling delay blocks, malfunctions can occur, for example the firing front of the pyrotechnic block ends prematurely. In order to overcome this disadvantage, straight or straight fuel sets are used. A disadvantage of this is the relatively short overall length in the case of delay sets arranged transversely to the main axis of the ammunition. The length of the fuel set depends on the ammunition caliber.
  • the invention is therefore based on the object of proposing a pyrotechnic detonator which allows the greatest possible length of the delay set with reliable detonator ignition.
  • a bomblet 1 with a transfer charge 2 and an explosive charge 3 carries a housing 4 of a pyrotechnic detonator 5.
  • a jacket 6 with an opening 7 for a slide 8 connects the housing 4 to the bomblet 1.
  • 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:
  • the latter is located outside of the response range 32 of the detonator 17, as shown in FIG. 2.
  • 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 slider 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.
  • 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 arming of the delay detonator 27.
  • a slide 68 with the eccentric center of gravity 69 is secured by the firing pin 15 which interacts with the detonator 17 when the bomblet 1 strikes, see FIG. 1.
  • the slide 68 is slidably mounted in the housing 4 between guide rails 61.
  • the housing 4 has the only opening 7 for the slide 68.
  • the following are arranged in the slide 68: the detonator 17, two bores 63, 63 with web 64, a spring-driven firing pin 65, the ignition charge 29 and a U-shaped delay set 70 of a pyrotechnic delay device 60 with plate 71.
  • the ball 35 secures the firing pin 65. It rests on the guide 61.
  • the guide 61 and the housing 4 are provided with a recess 14.
  • the pyrotechnic self-dismantling device is started as follows: The centrifugal forces move the slide 68 into the position 72, which is secured in a known manner.
  • the ball 35 falls into the recess 14 and thereby releases the firing pin 65, which ignites the igniter 29. After the predetermined burning time of the delay set 70, the latter ignites the detonator 17. This initiates the explosive charge, not shown, of the bomblet 1.
  • the large overall length of the delay set 70 with which relatively extremely long burning times can be realized is advantageous.
  • the easy and clear handling of the slide 68 is provided by the integrated structural units, as already described for FIG. 3, namely firing pin 65, pyrotechnic delay device and detonator 17.
  • a spring 66 brings the slide 68 into focus, including the firing function of the firing pin 65.
