Definitions

  • the present invention relates to an impact detonator for a projectile for igniting an active mass after impact on one Obstacle.
  • the well-known impact detonators have a high one Danger potential mainly due to the possible existence of duds. Because it happens, especially with Hit on a soft floor, not to ignite the Active mass, there is a dud, whose active mass can generally still be initiated.
  • claims 2 to 12 relate to particularly advantageous embodiments of the impact detonator according to the invention.
  • the pyrotechnic composition is an incandescent material such as Si / Pb 3 O 4 or the like.
  • An embodiment of the invention is characterized in that the pyrotechnic mass is preceded by a first decelerator in the ignition chain, in particular if the projectile can be fired when fired.
  • the pyrotechnic mass or the first delay piece electrical, like a primer, a primer or the like, or pyrotechnic, like over Clouds of propellant charge from black powder or the like at Firing or ejecting the projectile is ignitable.
  • the pyrotechnic igniter the active mass or a second ignition charge and the active mass includes.
  • the movable mounting of the pyrotechnic mass relative to the pyrotechnic igniter is a friction bearing that only starts a relative movement certain pressure allowed.
  • the movable mounting of the pyrotechnic mass relative to the pyrotechnic igniter comprises a shape memory element or a fuse, that a relative movement only after a certain one Heat input allowed.
  • the movable bearing can be clamped using Have shear pins.
  • Another embodiment of the invention is by a marked second delay piece, after the Delay time a self-destruction of the projectile is initiated.
  • the invention proposes that the delay time of second delay piece longer than the delay time of the first delay piece.
  • the second Decelerator of the pyrotechnic mass in the ignition chain is connected downstream or in parallel.
  • first and / or second delay piece a mechanical or electronic timer.
  • the invention is therefore the surprising finding based on the fact that a pyrotechnic impact detonator pyrotechnic mass, which, for example, at Firing a projectile or when ejecting one
  • the interior of the projectile is lit and made to glow, possibly also after a defined delay time, and in the case of normal operation by the shock of one Surcharge from a previously fixed position on a, in Ignition means arranged behind the ignition chain is moved, this ignites and thus the function of the Missile fires, or in the case of a dud, in said fixed position burns out, so that the ignition chain to Effective mass due to the lack of a link can be started again on its own, i.e. the dud for example, can be safely recovered.
  • the pyrotechnic mass can also be installed in a stationary manner, while the igniter is movably mounted.
  • mechanical or electronic timer in the invention pyrotechnic impact detonators are provided, the one Ensure overflight protection, the pyrotechnic mass ignite as well as for a certain period of time Keep the surcharge function ready and / or initiate self-destruction.
  • a pyrotechnic impact detonator according to the invention can be used in a variety of ways, for example in a bomblet storey, with a smoke missile or a practice ammunition any caliber.
  • FIG. 2 shows again schematically the essential parts of the Pyrotechnic impact igniter according to the invention of Figure 1.
  • the pyrotechnic impact detonators of Figures 3 to 7 differ from that according to FIG. 2 by using a or two timers.
  • 3 is a first Delay piece 7 is provided, particularly when the ignition of the projectile on launch is useful to a To ensure flight safety, the pyrotechnic phrase too ignite and in for a certain period of time To keep it operational.
  • the impact detonator according to FIG. 4 is a second one Delay piece 8 of the pyrotechnic mass 3 downstream to self-destruction after duds trigger a predetermined period of time.
