Definitions

  • the invention relates to a pyrotechnic self-dismantling device for ammunition according to the preamble of claim 1.
  • DE 43 21 941 A1 describes a self-dismantling device for an igniter Ammunition described in which a U-shaped pyrotechnic delay set in a slide is arranged.
  • the slide can be moved in a housing stored.
  • a tapping hammer is in the housing and outside the slide stored and is intended to then a tap set of the delay set ignite mechanically when the slide is in focus.
  • the object of the invention is therefore on the one hand to reduce the dud rate, on the other hand to show ways that cost-effective manufacture of the pyrotechnic Allow self-decomposition with the longest possible delay time.
  • the pyrotechnic self-dismantling according to the invention is with respect to its holes easy to incorporate pyrotechnics and in terms of ignition mechanism under construction. Two holes lying next to each other at an angle intersect their ends to ensure a flammable cross section result in a V-shaped arrangement. This arrangement is simpler Way with suitable pyrotechnics and ensures a safe and timely Function.
  • a flat, spring-driven tapping hammer is at the head end the slide is stored in a space-saving manner and connected to it. That flat tapping hammer Allows long holes in the given circular cross-section the foot of a bomblet.
  • the large bore lengths are a requirement for a long delay time of the pyrotechnic self-disassembly. Ensuring the back of the tapping hammer covers the outlet side Amplifier set and protects it against possible mechanical interference, that could impair the function of the amplifier set.
  • a pyrotechnic self-destructor 1 consists of a housing 3 with a foot 14, a locking pin 46 with pocket 53, a firing pin 60 with a threaded nut 63 and threaded connection 62, one connected to the firing pin 60 Stabilizing belt 65 and a slider 7.
  • the slide 7 is mounted in guides 4 to 6 of the housing 3 so as to be linearly displaceable.
  • the slide 7 has a V-shaped recess 77 in the form of bores 78, 82 and form an angle 83.
  • An ignition device 8 is at the head end 24 on the slide 7 by approximately 180 ° pivoted.
  • the ignition device 8 consists of a tapping hammer 10 which is approximately in the form of a hinge band.
  • the tapping hammer 10 is mounted on a pin 36 fastened on the slide side and via a on the pin 36 arranged torsion spring 37 can be driven.
  • the tapping hammer 10 has a Flat piece 11 with an ignition needle 12.
  • a free end 90 of the flat piece 11 protrudes to the circumference 22 of the foot 14 and gropes a not shown, over the housing 3 inverted bomblets. This bomblet locks in addition to the locking pin 46 the tapping hammer 10.
  • the locking pin 46 is in a bore 44 the tapping hammer 10.
  • a niche 45 on the slide 7 takes the tapping hammer 10 including the Slider 7 attached pin 36.
  • the pin 36 is in a foot 43 of the Slider 7 riveted.
  • Both the foot 43 and the base side of the slide 7 are with circular arc sections 84, 85 provided corresponding to a radius 76 of the foot 14.
  • the circular arc sections 84, 85 lie on the circumference 22 of the foot 14. Thus extends the slide 7 over a maximum distance.
  • the bores 78, 82 lie in the end faces 86, 87, with a rear side 47 of the tapping hammer 10 covers a reinforcement set 32 with a cup 34.
  • the aforementioned reinforcement set 32 is located in the same way in the V-shaped Recess 77, such as the tapping set 30 with cup 34 and the time delay burning pyrotechnic set 31.
  • the intersecting bores 78, 82 overlap in the area of Base 79 of the slide 7 and form an approximately lenticular focal cross section 88 (Fig. 3) as a transition cross-section for the continuous front of the pyrotechnic Sentence 29.
  • a stop 80 is provided on the slider 7, with a shoulder 81 of the foot 14 corresponds.
  • this spring-driven has a clockwise 180 ° movement and strikes at high speed with the ignition needle 12 in the cup 33 of the tapping set 30 and ignites the set 30.
  • the trigger set 30 and thus the time-delayed set 31 are ignited So regardless of the position of the slide 7 in the housing 3. This is the great security to avoid dangerous unexploded ordinances. Interfering influences that prevent ignition of the pyrotechnic set 29 or would be excluded.
  • the firing pin 60 punctures the detonator 35, which is thereby ignited and detonates the explosive charge, not shown, of the bomblet. If the detonator 35 is not ignited due to interference, the pyrotechnic set, in particular the amplifier set 32, ensures that the detonator 35 is ignited.
