Definitions

  • the invention relates to a detonator for a bomblet of an artillery grenade according to the preamble of claim 1.
  • a detonator for a parachute-delayed submunition of an artillery grenade, in which a detonator carrier which is pivotable about an axis is provided.
  • a spring rests on the detonator carrier; this tries to move the detonator carrier from the safeguard to the focus.
  • the detonator carrier is secured by a spring pin. The spring pin is unlocked by unfolding the parachute. Because of the two aforementioned spring elements, there is a risk that the igniter will not work properly due to material fatigue or breakage of the springs. This creates unwanted duds.
  • a fuse for an axially movable striker with a firing pin to ignite the detonator consists of detachable pins that fix the striker in a guide tube. The pins are only sheared off and the detonator fired when the ammunition accelerates accordingly.
  • the loads on the fuse parts of a bomblet are very high when an artillery shell is fired. Accordingly, the igniter parts should be robust and simple.
  • the invention is therefore based on the object of proposing a simple detonator for a bomblet which has two fuses which are independent of one another.
  • bomblet 2 In an artillery grenade 1, several bomblets 2 to 4 are stacked one behind the other.
  • the bomblet 2 which will be described in detail here, has an envelope 6 filled with explosives 5, the envelope 6 abutting on the front side of an envelope 7 of the bomblet 3.
  • the cover 7 completely covers part of the bomblet 2 with a detonator 8 and a folded parachute 9 with lines 13 of the bomblet 2.
  • the igniter 8 lies predominantly in a shaped charge lining 10 for an explosive charge 11 of the bomblet 3.
  • the lining 10 is fixed in the shell 7 by a ring 12.
  • the igniter 8 consists of a slide 16 which can be moved in the direction of the arrow 15.
  • the slide 16 contains a tapping-sensitive detonator 17 and has openings 18 and 19 for the piercing needle 20 of a racket 22 which is movable against spring force and for a driving lever 25.
  • the lever 25 is rotationally connected to a locking lever 26.
  • the locking lever 26 consists of spring plate and rests against the casing 7 in the prestressed state.
  • the striker 22 abuts a deformable locking washer 30.
  • the locking washer 30 is attached to a post 31 of a plate 34 crimped into a housing 33.
  • the function of the igniter can be seen from FIGS. 2 and 3.
  • the locking disk is deformed by the striker 22 according to FIG. 2 as a result of the launch acceleration, the striker 22 being moved in the direction of arrow 56.
  • the ignition needle 20 is disengaged from the slide 16.
  • the spring 21 holds the striker 22 in the position shown in FIG. 2.
  • the bomblets 2 to 4 are now separated from one another.
  • the prestressed securing lever 26 swings radially outward so that it is exposed to the flow of air, see arrow 57.
  • the air inflow force will now tear the safety lever 26 in the direction of arrow 56.
  • the securing lever 26 pushes the slide 16 into the armed position according to FIG. 3 via the driving lever 25.
  • the safety lever 26 disengages and flies away.
  • the lever 25 secures the slide by engaging a step 27.
  • the detonator 8 is now fully unlocked.
  • the striker 22 now moves in the direction of arrow 58 due to the delay and stings the detonator 17.
  • the ignition of the explosive charge 5 is thus initiated.
