Definitions

  • the invention relates to a spin-stabilized bomblet projectile with bomblets and the further features of the preamble of the claim.
  • the filling pieces are usually made of plastic or aluminum and serve both to fix the bomblets in the carrier projectile and to transfer the swirl of the carrier projectile to the bomblets.
  • the longitudinal and transverse moments of inertia of the bomblet carrier projectile, which determine the flight stability, are essentially determined in these known projectiles by the masses of the bomblets, the floor of the projectile, the carrier projectile envelope and the projectile tip and the ejection charge located in the projectile tip.
  • a rotating projectile is regarded as stable if an angle of attack generated by a fault also disappears.
  • the invention is therefore based on the object of achieving the mass distribution (or moments of inertia) required for flight stability in a particularly simple manner in bomblet carrier projectiles with a thin casing.
  • this object is achieved by a spin-stabilized bomblet projectile with the features of the characterizing part of the patent claim.
  • Fig. 1 denotes a bomblet carrier floor, 2 the carrier floor tip in which the ejection charge 20 is located, 3 the shell of the carrier floor and 4 the bottom of the carrier floor.
  • FIG. 2 shows a cross section through the above-mentioned bomblet carrier floor.
  • the bomblets were again designated with 30, the shell of the carrier storey with 3 and the filler pieces which are present in this cross-sectional position with 34.
  • the bomblet carrier storey 1 which can be, for example, a 155 mm storey, ignites the ejection charge 20 after a predetermined period of time.
  • the bomblets 30 are pushed out to the rear by the gas pressure which arises in the tip-side part of the storey. In the present example, six bomblet layers and seven bomblets per layer are dropped on the target area.
  • the thinnest possible shell 3 should be used, i.e. H.
  • the ratio of the wall thickness of the carrier shell 3 to the tube caliber should be ⁇ 0.05.
  • the fillers 31, 32 and 35, 36, 37 were chosen from steel.
