Definitions

  • the invention relates to a sabot for a sub-caliber projectile. It consists of segments held together by known means, which form a central tube inside, which is the Floor encloses. The segments have projections at the front and rear on the outer circumference with guide surfaces for guiding the sabot in a launching device, for example in a gun barrel or a gun barrel.
  • Such a sabot known from DE-PS 17 03 507 is intended to increase the total driving force of the projectile without increasing the total mass accordingly. That is why it has to be relatively light.
  • drive cages are not designed as full-walled, cylindrical parts, but one sees areas with a smaller diameter than the diameter of the front or rear or between two projections Firing device or the guide surfaces of the sabot before. This results in a corresponding saving in material and weight.
  • One-armed ammunition cannot be used in existing loaders of some weapons, because in their magazine the charge control or effect sensors or levers are arranged so that they depend on a sabot wall with its largest diameter in the area resulting from the mentioned diameter reduction.
  • the problem cannot be solved by designing the entire sabot as a cylindrical part, since this would result in an excessive increase in the sabot weight, which would inevitably lead to a reduction in the performance of the projectile.
  • the projectile weight and sabot cage weight are coordinated with one another in the sense of optimal guidance and optimal sliding through the launch tube, so that a significant increase in the weight of the sabot cage and thus a shift in the center of gravity means that the segments slide smoothly and, if necessary, are thrown off after sliding through more is achieved.
  • the object of the invention is therefore to improve a sabot so that it can be adapted to the construction of any loader available or usable for the corresponding caliber while avoiding the disadvantages mentioned above.
  • This makes it possible to use the same ammunition even with differently designed control or actuation elements of the loaders.
  • This makes it possible to mass produce the same ammunition, of which only a part may have to be retrofitted.
  • the object is achieved in a sabot described at the outset according to the invention in that an insert piece reaching at least up to the area of the loading process of the launcher or contact levers in the magazine of the loader is bridged in such a way that the outer wall of the sabot in this area is supplemented to a cylindrical surface with the same or almost the same diameter as that of the projections, and that only a slight increase in weight compared to the weight of the sabot occurs due to the appropriate design of the insert and / or choice of material for the insert. This is in the range of about 10%.
  • the insert piece can bridge the entire space between the projections. This enables a particularly simple attachment of the insert to the segment.
  • Parts of a thin-walled, sleeve-like sheet can serve as the insert of each segment, or a plastic tube can be used from which the insert is worked.
  • each segment can be formed from parts of a plastic turned part or it can consist of a plastic injection molded part with predetermined breaking points, slots or the like. be made.
  • a particularly secure and simple attachment of the insert in the segment results from the fact that according to the invention the insert is supported on one side with an attachment part in a circumferential groove of the one projection and on the opposite projection of pins, screws or the like protruding through holes in this projection.
  • the insert is glued to the segments for secure mounting, and the pins or screws can also be glued to the segments and the insert.
  • the insert can also be a foamed plastic body filling the space between the projections, e.g. made of rigid foam. This does not increase the weight, since you can adjust the density of the rigid foam plastic.
  • the drawing shows a section through a segment.
  • Three segments are preferably provided. 1 with the segment body is designated, which has the projection 2 on the left and the projection 3 on the right. Between these projections is the insert 5, which is anchored on the left with a shoulder 6 in a circumferential groove 7, and which is / is held on the right with the pin 8, which is guided through the hole 9. 4 with the cavity in the interior of the sabot segments in which the floor is received.
  • 10 and 11 designate circumferential grooves in which a guide ring or a band for holding the segments and for guiding them can be arranged.
  • An advantage of the new sabot is that the inserts can be attached to it at any stage of manufacture.
