Definitions

  • the invention relates to a drive pot for spin-stabilized sub-caliber projectiles.
  • a plastic drive pot for spin-stabilized sub-caliber projectiles is known.
  • the drive pot has a circumferential groove and axial slots in the area of a projectile rear in its wall enveloping the projectile, the slots projecting from the front end of the drive pot to almost the circumferential groove.
  • the section of the thin-walled drive pot should still be divided into four parts in the weapon barrel because of the four slots, which laterally move away when the gun barrel emerges from the gun barrel.
  • the bottom, closed part of the drive pot has a greater air resistance than the projectile after leaving the gun barrel, so that the drive pot is separated from the projectile. After detaching the floating pot remnant, it flies a larger distance directly behind the projectile. There are cases, especially when working at small distances, in which this fact affects the projectile behavior.
  • a sabot for spin-stabilized lower-caliber projectiles in which a retaining ring with part of its length holds four wall sections together at the rear. These wall sections keep a projectile in a central position to the sabot. After the sabot and the projectile have been fired, the retaining ring tears after exiting the weapon barrel due to the centrifugal forces of the wall sections. Since the locking ring is not affected by the fields of the drawn weapon barrel when it is fired, it can happen that, due to the relatively high tensile strength of the locking ring, the sabot detachment occurs very late and thereby adversely affects the accuracy of the projectile.
  • the invention is based on the object of proposing a drive pot for spin-stabilized lower-caliber projectiles which separates from the projectile immediately after the weapon barrel muzzle.
  • the fields of the drawn weapon barrel advantageously cut the necessary predetermined breaking points into the guide band.
  • This ensures that the drive pot including the pot sleeve is torn open several times immediately after the pipe mouth due to the centrifugal force of the segments of the drive pot.
  • the segments can consist of steel, aluminum, titanium or plastic.
  • the guide band has predetermined breaking points exactly above the dividing joints of the drive pot. Irrespective of this, a trouble-free detachment of the segments of the drive pot is ensured in the case of offset predetermined breaking points with respect to the dividing joints. Further advantages lie in the simple and inexpensive manufacture of the drive pot with the guide belt.
  • the drive pot advantageously consists of three segments.
  • a drive pot 1 encloses a projectile tail 2.
  • the drive pot 1 has a guide band 4 with a rear cone 5 in a groove 3.
  • a pot sleeve 6 made of aluminum is crimped or glued into the cone 5.
  • the drive pot 1 consists of three segments 7. Between these there are dividing joints 8.
