Definitions

  • the invention relates to a submunition according to the preamble of claim 1.
  • Such a submunition descending on the brake parachute into the target area is known from US Pat. No. 4,974,515 for use against hard and semi-hard targets in a protected position.
  • the cylindrical warhead has an outer surface covering made of P charges, which are fired for an all-round fan effect with a slightly increasing average splinter direction when the submunition descended into the target area hits the ground hard; while the direction of the splinter is inclined slightly downwards if the brake parachute is intercepted comparatively softly in the branches or entablature of a protective cover over the target object.
  • This mechanism of action has advantages over the conventional bomblets used as cluster munitions with axially forward-oriented beam-forming shaped charge inserts, which have to strike the target object directly for a desired effect; however, the generic effect scenario is ineffective against target objects in a semi-protected position behind earth walls, walls, sandbag barriers or the like.
  • Such protective devices can indeed be overcome by the known detonator submunition as described in DE-Z WEHRTECHNIK issue 10/1985 on page 115, that is to say by a P-charge warhead which is suspended from the rotating screen while searching for a spiraling path attacks a hard target object from above using a search detonator sensor; but the technological outlay for search detonator P-charge warheads used as submunitions is justified only for direct combat against indirect firing; when used against semi-hard or unarmored targets in a semi-protected position, the cost-benefit ratio would be too unfavorable.
  • the present invention is based on the technical problem of creating a submunition which can be used in a cost-effective and effective manner against semi-hard targets in semi-covered position and which, if possible, also opens an active component against unprotected unarmored target objects if the aforementioned main target class should have been missed.
  • submunition will self-disassemble with the formation of an essentially horizontal heavy metal splinter fan with an effect against the surrounding area unprotected target objects.
  • the submunition according to the invention thus represents an inexpensive and effective combination of a conventional bomblet with the search detonator function of intelligent submunition.
  • a submunition 11 of several that were axially linked by means of a carrier grenade from a howitzer or, preferably, by means of an artillery rocket from a launcher over a pre-enlightened target area 12, in which semi-hard targets in semi-covered position (such as armored personnel carriers or Command posts behind earth walls) must be fought.
  • the submunitions 11 ejected axially from the carrier shell are separated from one another with release from the transport shell and distributed in the course of aerodynamic braking (by means of a brake parachute or a brake ballute), before the braking device becomes ineffective (in particular thrown off) in order to release a rotating screen 13.
  • the submunition 11 on the lines 14 of the rotating screen 13 is at an aspect angle 15 of the order of about 30 ° (measured between the vertical 16 and the warhead Direction of action 17) articulated.
  • This articulation rotates around the vertical 16 in the course of the parachute-braked sinking of the submunition 11 with a few Hertz.
  • the search direction 18 of a sensor 19 in the plane of the target area 12 describes an approximately circular but Search path 20 contracting like a spiral for a target object 21 to be combated.
  • sensor 19 can work passively, that is to say respond to electromagnetic radiation energy that originates from target area 12. This can be reflected and locally shadowed by the target object 21 vertical radiation, which is recorded by means of a radiometer sensor 19, or directly emanating from the target object 21 and significant to the environment, which is recorded by an infrared sensor 19.
  • the sensor 19 can, however, also be an active one, which scans the terrain in the target area 12 according to the search path 20 according to the principle of the retroreflective technology and responds to a significant jump in height originating from the target object 21; or it is a combination sensor 19 which works both passively and actively and evaluates a signature link for the target acquisition, as is known as such from the technology of the search detonator sensor system (cf. GB 21 44 523 A).
  • the cylindrical explosive charge of the warhead 22 is ignited and a shotgun cone of heavy metal balls 23, with which the one pointing in the direction of action 17 Face of the warhead 22 in front of the explosive is accelerated obliquely from above in the direction of the target 21.
  • the target 21 is not protected against this direction of action by means of protective measures against direct fire (such as side armor and earth wall), so that a great effect of the fired warhead 22 in the selectively detected target object 21 is ensured.
  • the search path 20 is due to the small remaining residual height and the small remaining radius Acquisition of a semi-hard target 21 can no longer be expected.
  • the active sensor 19 acting as an altimeter or z. B. serve an additional radar altimeter. Now the constructive locking of the aspect angle 15 is released on the submunition 11, so that the warhead 22 still hanging on the rotating screen 13 swivels into a vertical orientation of its direction of action 17 due to gravity. Then, e.g. B.
  • spherical splinter cone is shown in Fig. 1b and only the splinter cube fan in Fig. 2b.
  • both effects occur simultaneously, but only one function is effective from a height and only the other function in the plane.
  • a targeted detonation can be brought about in order to selectively promote one of the two fragmentation mechanisms.
