Definitions

  • the invention relates to a projectile with a tubular projectile body, which has a conical, rearwardly widening inner wall at the rear end and with a sabot base part on which the projectile body is supported when fired and which detaches when the projectile emerges from the weapon , wherein the sabot base part has a conically-shaped section which also widens towards the rear and projects into the conical section of the projectile body at the rear.
  • the projectile body has at its rear end an annular shoulder on which the sabot base part is supported.
  • this shoulder has the disadvantage that it is exposed to a large surface pressure when the projectile is fired when the projectile is narrow, and on the other hand it has the disadvantage that it has an unfavorable flow in terms of flow technology.
  • the conical section of the sabot base part must not be supported on the conical inner wall of the projectile body, since otherwise the sabot body and sabot base part would wedge into one another and a detachment of the sabot base part from the projectile body after the projectile emerged from the weapon would no longer be guaranteed because the slope the conical inner wall of the projectile body is designed to be self-locking for fluidic reasons.
  • the object of the invention solves on the one hand the task of avoiding damage during the launch without reinforcing the rear edge of the tubular projectile body, since this edge is too weak for the large forces occurring during the launch and on the other hand solves the task of safely detaching the sabot base part to ensure from the projectile body, ie to avoid that the conical section of the sabot base part wedges in the conical inner wall of the projectile body.
  • this object is achieved in that an at least two-part annular wedge is arranged between the conical inner wall of the projectile body and the conical section of the sabot base part, which is conical both outside and inside.
  • This wedge has the advantage that a reliable detachment of the sabot base part is guaranteed after the projectile has been fired, without the sabot base part wedging into the tubular projectile body.
  • the bullet according to the invention is made consisting of a sabot base part 10, a three-part annular wedge 11 and a tubular projectile body 12.
  • the sabot base part 10 consists of a cylindrical rear section 13, a central conical or conical section 14 and a front cylindrical section, which is referred to as head 15.
  • the conical middle section 14 of the sabot base part 10 is surrounded by the three-part annular wedge 11.
  • the sabot base part 10 projects with the head 15 and the central conical section 14 into the interior of the tubular projectile body 12.
  • Both the inner wall and the outer wall of the tubular projectile body 12 consist of three sections, namely a cylindrical inner wall 16, a cylindrical outer wall 17, one front conical inner wall 18, a front conical outer wall 19, a rear conical inner wall 20 and a rear conical outer wall 21.
  • the front inner wall 18 and the front outer wall 19 form a sharp edge 22.
  • the rear outer wall 21 and the rear inner wall 20 define one narrow annular end face 23.
  • the three-part annular wedge 11 has a conical outer wall 24 and a conical inner wall 25. These two walls 24 and 25 delimit a wider annular end face 26 at the front and a narrower annular end face 27 at the rear.
  • the cone angle ⁇ is selected such that the annular wedge is self-locking in the tubular projectile body 12.
  • the cone angle!, J is selected such that the annular wedge 11 does not bear against the conical section 14 of the sabot base part 10 in a self-locking manner.
  • the smaller cone angle i3 ensures that after the projectile has been fired, the sabot base part 10 reliably moves away from the projectile body 12, i.e. can detach from the annular wedge 11.
  • the annular wedge 11 can reliably detach itself from the tubular projectile body 12, although the cone angle oC is selected such that the annular wedge 11 is self-locking in the tubular projectile body 12.
  • the conical outer wall 24 and the conical inner wall 25 of the annular wedge can be provided with an oxalic layer.
  • a plastic layer or a lubricating layer e.g. Fat or graphite.
  • An air gap between the parts of the annular wedge 11 facilitates detachment from the projectile body 12.
