Definitions

  • the invention relates to a spin-stabilized carrier projectile with at least two submunition projectiles, as is defined in more detail by the preamble of claim 1.
  • Carrier projectiles are known, for example, from Flume: "Artillery ammunition: better effect at the target", Wehrtechnick 1985, Volume 10, pages 112 to 120.
  • the carrier floor is z. B. shot with the help of a gun.
  • the carrier projectile contains two or more target-detecting submunitions which are ejected from the projectile at a predetermined time. After this ejection process, the swirl is first reduced and the submunitions decelerated. The speed is usually braked with the help of a parachute and the swirl is reduced with the help of so-called swirl wings.
  • the swirl brake and the parachute required for speed reduction are blown off and another parachute opens, on which the submunition body glides to the ground and makes a rotating movement for scanning the target area.
  • the active part of the submunition is fired, so that, for example, a projectile-forming charge is generated which then hits the target.
  • a disadvantage of this known ammunition is above all that the submunitions fly relatively close to one another in the target area and therefore several submunitions hit a certain target, while other targets in the target area are not hit.
  • the object of the present invention is to further develop a spin-stabilized carrier projectile of the type mentioned at the outset in such a way that the submunitions are distributed over the largest possible target area in the predetermined target area.
  • Fig. 1 denotes a projectile that was fired, for example, by means of a gun, not shown.
  • This floor 1 contains z.
  • the braking elements 20 and 30 both reduce the speed of the submunitions 200 and 300 and reduce the swirl. As soon as both variables have dropped to a predetermined value, the braking element 30 is repelled by the submunitions (not shown).
  • the brake elements 20 and 30 have different dimensions (outer diameter D1 and D2) and thus provide for a separation of the submunitions 200 and 300 due to the different air resistance. It is therefore possible, by suitable selection of the diameter of the brake elements 20 and 30, for the submunitions in the predetermined target area spread over a relatively large target area.
  • the submunitions can then be braked further, for example, by unfolding a parachute, and the target area can be scanned by the rotating movement of these bodies (cf. the individual Flume, "Artillery ammunition: better effect at the target”; Wehrtechnick 1985, Issue 10, p. 112) ff).
  • the submunition body 300 contains the actual active body 31, which contains, for example, a hollow charge
  • the housing 32 which handles the signal processing and a swing-out antenna (not shown) can contain and a detachable support structure 33, on which the brake disc 30, for example by means of screws 330, is attached.
  • the annular projection 331 of the support structure body 33 encloses the packaging space for the brake element 30.
  • FIG. 3 shows a top view of the brake disc according to the invention as shown in FIG. 2 viewed from the rear.
  • 36 is a hem band, which both has the task of preventing the brake disc from tearing in its edge region 35 during the high rotations of the projectile 300. Even more important is the task of the hem band 36 to ensure that a higher mass distribution prevails in the edge region 35 than in the remaining region of the fabric brake disc.
  • a further stability of the fabric brake disk 30 is achieved by additional belt straps 37, which are preferably arranged in a cross shape. As a result, the strength of the entire brake element 30 increases considerably.
  • Polyamide or a tear-resistant plastic film has proven to be a particularly good material for the fabric brake disc, but also for the belt straps and the hem band.
