Definitions

  • the invention relates to a safety device for a pyrotechnic self-igniter for bomblets according to the preamble of claim 1.
  • DE-OS 33 33 312 it is known to provide a pyrotechnic self-dismantling device in an igniter for a bomblet. This ensures that in the event of an ignition failure, for example if the firing pin is blocked, a dud is avoided in any case.
  • the detonator which is arranged in a slide which is movable transversely to the main axis of the bomblet, is ignited via a pyrotechnic delay device after a certain time.
  • the slide is secured in a positive engagement of the firing pin in the slide.
  • the firing pin is reset against the flight direction over a certain stroke, so that the unlocked slide moves radially outward due to the centrifugal forces.
  • a firing pin arranged on the housing wall of the igniter then strikes a firing rate arranged in the slide, which in turn ignites a pyrotechnic delay rate.
  • the triggering of the delay set depends on the slide movement. Therefore, if the slide is jammed in the safety device, there is in any case a dud with a still sharp detonator. This should be avoided under all circumstances.
  • the object of the invention is therefore to propose a safety device for a pyrotechnic self-igniter, which ensures the ignition of the pyrotechnic retardation set independently of the slide movement.
  • the firing of the firing pin ensures that the pyrotechnic retardation is fired. If the stroke is not carried out, there is also a dud, which, however, is not classified as a dangerous dud due to the clearly recognizable condition.
  • the time of ignition of the pyrotechnic delay set which is more precisely than previously defined, is also advantageous, so that the delay time can be defined more precisely.
  • a bomblet 1 has a casing 2 with explosives 3 and with a transfer charge 4 and a detonator housing 5 fastened with the casing 2.
  • the igniter housing 5 there is an opening 6 on the side for a slide 7 which can be pushed out of the latter.
  • the firing pin 12 can be moved in a known manner by aerodynamically acting means.
  • the firing pin 12 is mounted in a guide 13 of the housing 5.
  • the slide 7 contains a detonator 20; in bores 21, 22 a spring-driven striking pin 23, a free space 24, an ignition set 25 and an angled pyrotechnic delay set 26.
  • a locking lever 30 is pivotally mounted via a pin 31.
  • the arm 32 of the locking lever 30 is in contact with a cylindrical portion 14 of the firing pin 12, while the arm 33 rests on a collar 27 of the firing pin 23.
  • the arm 33 sets the striking pin 23 in the securing shown.
  • the firing pin 12 is moved in the direction of the arrow 11 over a certain distance.
  • the arm 32 scans the section 14. After this section 14 has left the sensing range of the lever 32, the conical section 15 comes into the area of the arm 32. This section 15 then releases the arm 32 for the spring-powered pivoting movement of the lever 30.
  • a spring 28 can now move the striking pin 23 in the direction of arrow 29.
  • the arm 33 is pushed aside by the collar 27, causing the locking lever 30 to pivot in the direction of the arrow 35.
  • the striking pin 23 then ignites the firing rate 25, which in turn initiates the delay rate 26.
  • the detonator 20 is ignited by thermal or detonative action.
