Definitions

  • the invention relates to a sabot for a sub-caliber projectile, which is segmented, and which has a support part defining a positive-locking zone between it and the projectile, a front part connected to the support part and formed with an air pocket, a rear fixing part connected to the support part and an intermediate the front part and the rear fixing part provided outer part.
  • Such a sabot is known from DE 36 25 730 A1.
  • the outer part has a fibrous portion that absorbs tensile stress and is connected to the carrier part.
  • the fibrous portion has individual parts that extend between a front and a rear fixing area.
  • This The sabot consists of a large number of individual parts, the individual parts of the fibrous portion in particular resulting in a considerable amount of assembly work in the production of such a sabot.
  • This sabot can be provided with radial projections for rear support.
  • the invention has for its object to provide a sabot of the type mentioned, which is simple in design and has relatively few individual parts, so that its manufacture is comparatively simple, and which is not pressed during its movement through an end pipe, but rather improves the flight characteristics is pulled.
  • the carrier part has a low weight in relation to the front part
  • the rear fixing part has a low weight in relation to the front part or to the carrier part and consists of a damping material.
  • the front part connected to the carrier part preferably consists of a specifically heavier material than the carrier part.
  • the carrier part can bpsw. from one Be aluminum alloy.
  • the connection between the front part and the support part can bpsw. done by screw elements.
  • the connection of the rear fixing part to the carrier part can be done by gluing, spraying or the like. respectively.
  • the rear fixing part preferably has two concentric collars which are connected to one another by means of connecting ribs.
  • Such a fixing part is simple to implement and can be mechanically firmly connected to the carrier part in a simple manner.
  • the outer collar of the rear fixing part is preferably surrounded by a retaining ring which determines the caliber of the sabot.
  • This retaining ring preferably consists of a material that is gentle on the weapon barrel.
  • the front part of the sabot may be surrounded by a second retaining ring which determines the caliber of the sabot.
  • This second retaining ring can consist of the same material as the retaining ring provided on the rear fixing part.
  • the outer part of the sabot is preferably designed as a tubular sleeve.
  • the tubular outer part serves to protect the weapon barrel and at the same time for stabilization purposes.
  • FIG. 1 shows a sabot 10 cut longitudinally on one side and a projectile 12 shown in sections
  • the sabot 10 has a carrier part 14 which forms a positive-locking zone 16 between it and the projectile 12.
  • the carrier part 14 consists, for example, of an aluminum alloy.
  • a fixing part 18 is connected at the rear to the carrier part 14, for example by gluing.
  • the fixing part 18 can consist of a polyamide.
  • the fixing part 18 has an outer collar 20 and an inner collar 22, which are arranged coaxially and are connected to one another by connecting ribs 24. From Fig. 2 it can also be seen that the fixing part 18 is divided into segments. The carrier part 14 is also segmented accordingly. The rear fixing part 18 is formed on its outer circumference with a circumferential groove 26 in which a retaining ring 28 is provided.
  • a front part 30 is connected to the carrier part 14, for example by screw elements 32, the front part 30, which is segmented like the holding part 14, made of a specifically heavier material than the carrier part 14, so that the center of gravity S (see FIG. 1 ) is displaced far forward from the middle area of the sabot 10, so that a so-called sabot 10 results.
  • the front part 30 is formed on its outer circumference with a circumferential groove 34 in which a second retaining ring 36 is arranged.
  • the retaining rings 28 and 36 determine the caliber of the sabot 10.
  • the front part 30 is formed with an air pocket 38, which is used for the targeted use of the air flowing in after leaving a gun barrel.
  • the carrier part 14 is shaped in such a way that there is a gas pressure receiving surface 40 which passes through during the launch, ie during the passage the gun barrel is exposed to the propellant gases.
  • An outer part 42 which is designed as a tubular sleeve and is held on the bow side by a ring element 44, extends between the front part 30 and the rear fixing part 18.
  • This ring element 44 can be a sealing element, which can also be provided or instead of the second retaining ring 36 for determining the caliber of the sabot 10.
