Definitions

  • DE-Q 11 01 225 discloses a grenade of this type, the impact detonator of which has an axially displaceable impact body, the rear ignition needle of which is prevented from acting on the detonator in a secured position by a transversely displaceable slide.
  • Impact body is designed as a tube, in which an inner, forward-facing firing pin, an associated primer, two delay sets and a self-ignition set are housed.
  • the primer When fired, the primer is struck on the inner firing needle and ignites the two delay sets which are arranged on both sides of the inner firing needle.
  • the combustion of the shorter-burning delay set releases a spacer or allows it to melt, which keeps the rear firing pin of the striker pressed into a recess in the slide in a secured position, so that it is fixed against displacement.
  • the slide can move, making it possible for the rear firing needle to pass to the detonator upon impact. If this is done so that the detonator is not acted on, shortly thereafter, the self-igniting primer is ignited by the longer-burning second decelerating primer, which likewise initiates the action of the detonator by the rear firing needle.

  • a primer When fired, a primer is ignited, which in the secured position ignites the associated transfer delay charge. After leaving the tube, the combustion gases of the transfer delay charge move the slide into its end position in which the connection to the main charge has been closed.
  • the projectile provided with this device has neither a detonator nor a self-dismantling.

  • the accommodation of the ignition device in the base part improves the functional reliability of the grenades and increases the security of the front pipe and the ignition, since both can be controlled directly by firing.

  • This design enables the grenade to disassemble itself regardless of whether the impact was faulty, in particular too soft, or whether there was a malfunction, for example the striker jammed or the detonator could not be ignited, since the second ignition chain was activated when it was launched and after a period of time exceeding the flight time, detonates the explosive charge completely independently. There can therefore be practically no unsecured unexploded ordnance, since in the event of complete failure the slide is not pushed into the active position and both ignition chains are interrupted.

  • Both detonators are advantageously arranged in the passage bores of the slide itself, and in a further embodiment it is advantageous if the parallel branch of the self-dismantling delay set is divided on the slide side by a partition wall that can be destroyed by the gas pressure of the combustible self-dismantling delay set.
  • This increases the safety of the front pipe, since in the secured slide position a possible rollover of the burnable self-deceleration delay set into the burning detonator is thereby reliably avoided.
  • This danger could arise in the absence of a dividing wall in that, due to the short displacement path and bore cross sections caused by production technology, the easily ignitable burning detonator is very close to the end of the self-decomposition delay rate.

In the secured position, the impact piece is blocked in its movement, for example by a shear pin, the detonator firing needle not engaging in the third bore mentioned. When fired, the hammer is moved backwards and remains in the firing position of the primer, so that the slide movement cannot be hindered by the detonator needle.

Abstract

Grenade pouvant être tirée depuis un tube au moyen d'une charge de propulsion, et munie d'une fusée percutante constituée d'un détonateur (28) qui amorce une charge explosive (3) ou objet similaire et d'un élément de percussion qui se déplace axialement (5) avec un percuteur (8). De plus, la grenade est dotée d'une coulisse à ressort (24) pouvant être réglée à angle droit par rapport à l'élément de percussion (5) et qui est tenue par une goupille de blocage (12) pouvant se déplacer dans le sens longitudinal de la grenade. La grenade est également dotée d'une capsule-amorce (10) qui, lors de la mise à feu, est actionnée par un deuxième détonateur (7) de l'élément de percussion (5) par l'action de l'inertie de masse. Une charge pyrotechnique double (21, 22) est donc amorcée, dont la première partie (21) réalise le mouvement longitudinal de la goupille de blocage (12) et partant le dégagement de la coulisse (24), et dont la deuxième partie se présente sous la forme d'une charge à retardement qui se désagrège spontanément (22) et qui devient active en cas d'une percussion manquée. La charge à retardement qui se désagrège spontanément (22) constitue une section d'une deuxième chaîne d'amorçage qui comprend la chaîne d'amorçage à percussion, la coulisse (24) mettant les deux chaînes d'amorçage dans une position sûre et en même temps les bloquant en position active.
