Definitions

  • the invention relates to an igniter for a parachute or band-stabilized, rotating in flight bombed according to the preamble of claim 1.
  • an ignition and safety device for launching ammunition in which a slide under spring tension can be released via an ignition button that can be moved in a thread.
  • a stabilizing band connected to the firing needle brakes the firing needle with respect to the rotating ammunition, so that the firing needle tip lifts off the slide.
  • a self-dismantling device is not provided in this ignition and safety device.
  • the object of the invention is to propose a detonator for bomblets, which ensures that the detonator is ignited in any case in the absence of an ignition-relevant impact pulse.
  • the igniter should be highly sensitive and simple.
  • the pyrotechnic set serving as a timing element is arranged in the slide in a space-saving manner, together with the detonator and a disassembly needle biased by spring force.
  • This spring is the only energy storage element in the igniter. It only supports the centrifugal forces caused by the rotation, which also act on the cutting needle, for piercing the pyrotechnic block.
  • the firing needle fulfills a double function, it secures both the slide in the safe position and the disassembly needle in the safe position. This means that the self-disassembly activation is only coupled to the ignition needle, so that the pyrotechnic charge is ignited even when the ignition needle is unscrewed.
  • the time-delayed detonator firing caused by the kit runs over a period of time that is significantly greater than the flight time normally required to combat a target.
  • the required bore lengths for the pyrotechnic set in the slide are achieved in a small space, without the risk of undesired over-ignition of the set already burning in the first hole on the set arranged in the second hole.
  • a determination of the disassembly needle consisting of a few existing parts is achieved according to claim 4.
  • the ignition needle according to the invention is supported twice by the housing-side guide length and by the collar of a box-shaped sheet metal guide, so that a central ignition of the detonator is ensured.
  • a detonating needle that evades the centric ignition of the detonator cannot occur.
  • the detonator detonation achieved in a cost-effective manner is achieved by the firing needle sealing the collar of the box-shaped sheet metal guide with its cone opening. This contributes to the safe ignition of the explosive-side transmission set.
  • a single, lateral engagement of a safety slide mounted on the housing on the slide having the detonator is sufficient. Therefore, in the event of assembly errors in which, for example, the installation of the firing needle has been forgotten - within a group of several bobbins placed one on top of the other - undesired ignition of the detonator by the self-dismantling device cannot occur.
  • a spring force is not exerted on the slide.
  • the slide remains in the safe position - even if the ignition needle is missing. If the safety slide is possibly extended, it moves back into the safety hole when the impact pulse has subsided and positively fixes the slide again.
  • an additional securing of the slide is ensured in a structurally simple manner.
  • the positive locking of the slide in the association of bomblets is achieved by means of simple construction.
  • a relatively small impact pulse is sufficient for the ignition of the detonator upon impact.
  • An igniter 1 consists of a housing 2 with a guide length 11, a square opening 3, a bearing bush 4 designed as a square nut, an ignition needle 5 with thread 6, ring 7, cone opening 8, a non-rotatably fastened stabilizing band 9, a cap 10, a Safety slide 15, a bearing bore 17, a sheet metal guide 18 with a collar 19, a slide 20 with bores 25 to 29, a detonator 30, an approximately U-shaped pyrotechnic, time-delaying set 31, a disc 32, a disassembly needle 33, a spring 34, a sheet 35, a stop 36 and from a locking device, not shown, for the focusing of the slide 20th
  • the housing 2 is connected via screw connections 37 to an explosive shell 40 which has a transmission set 41.
  • Bombblets are combined in an association not shown, for example within a floor.
  • the stop 36 is located on the wall 38 of the housing.
  • the bomblets After ejection of the bomblets from a storey with swirl, the bomblets separate from one another, i.e. the bomblett bandage is dissolved and the stabilizing band 9 unfolds.
  • the sleeve 42 has released the slide 20.
  • the braking force of the stabilizing band 9 causes, compared to the rotating bomblet, that the firing needle 5 is unscrewed from the igniter housing 2 until the ring 7 rests on the bearing bush 4.
  • the ignition needle 5 unlocks the disassembly needle 33 and the safety slide 15 releases the slide 20.
  • the disassembly needle 33 ignites the pyrotechnic set 31, which burns up relatively slowly.
  • the firing needle 5 is then above the detonator 30. If the bomblet is now relevant to ignition, the firing needle 5 stings the detonator 30, which then ignites the transmission set 41 via a channel 46 in order to initiate the detonation of the bomblet.
  • the detonator 30 is ignited via the pyrotechnic charge 31 which has burned down to the detonator 30.
