Definitions

  • the present invention relates to an impact igniter for a Projectile for igniting an active mass after impact on one Obstacle.
  • the known impact detonators have a high hazard potential mainly due to the possible existence of unexploded ordnance. Coming namely, especially when hitting a soft floor, not to ignite the active mass, there is a dud, whose active mass can still be initiated.
  • this object is achieved by using a Detonated chain that has a pyrotechnic mass and a pyrotechnic igniter, the pyrotechnic Mass and the pyrotechnic igniter movable relative to each other, at least before the projectile hits the bullet Obstacle are stored separately from each other and themselves after hitting the projectile on an obstacle to ignite the Moving active mass towards each other.
  • 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 a first delay in the Ignition chain is connected upstream, especially if the projectile at Firing is ignitable.
  • the pyrotechnic Ground or the first decelerator electrically, as above one Ignition initiator, a primer or the like, or pyrotechnic, such as swathes of propellant from black powder or the like when firing or firing the projectile, ignitable is.
  • the pyrotechnic igniter 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 Includes shape memory element or a fuse, or a relative movement only from a certain heat input allowed.
  • the movable bearing can be clamped using shear pins exhibit.
  • Another embodiment of the invention is by a second Marked delay piece, after its delay time Self-destruction of the projectile is initiated.
  • the invention proposes that the delay time of second delay piece longer than the delay time of 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 represents electronic timer.
  • a pyrotechnic impact detonator is a pyrotechnic mass has, for example, when firing a projectile or lit when ejecting a floor structure and to glow brought, if necessary also after a defined Delay time, and in the case of normal operation by the shock a surcharge from a previously fixed position on a Ignition agent arranged behind it in the sense of the ignition chain is moved, this ignites and thus the function of the projectile triggers, or in the case of a dud, in said fixed Position glows, so that the ignition chain to the active mass due to the Lack of a link does not start up again on its own is settable, i.e. the dud, for example, is safe can be recovered
  • the pyrotechnic Mass be installed in a fixed position while the igniter is movable is stored.
  • Impact detonators are provided, which provide overfly protection ensure to ignite the pyrotechnic mass as well as a certain time period for the service function in Maintain operational readiness and / or self-destruction initiate.
  • a pyrotechnic impact detonator according to the invention can be used in many different 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 give way thereby from that according to FIG. 2 by using one or two Timers.
  • 3 is a first delay piece 7 provided that in particular when the projectile is ignited Launch is useful to ensure flight safety ignite pyrotechnic phrase and this for a certain Keep the period of time ready for operation.
  • 4 is a second pyrotechnic impact detonator Delay piece 8 downstream of the pyrotechnic mass 3 self-destruction in the case of unexploded bombs after a predetermined one Trigger duration.
  • the mode of action of the pyrotechnic Impact igniter according to Figure 5 does not differ basically from that according to Figure 4, i.e. it is for them Self-destruction essentially doesn't matter whether the second Delay piece 8, 8 'downstream of the pyrotechnic mass 3 or is connected in parallel.
  • Self-destruction essentially doesn't matter whether the second Delay piece 8, 8 'downstream of the pyrotechnic mass 3 or is connected in parallel.
  • the embodiments of the figures 6 and 7 is both a first delay piece 7 and a second delay piece 8, 8 'provided, with regard to of the second delay piece 8, 8 'in the two alternatives of Figures 4 and 5.
