  • Patent number: 5404816
    Abstract: A releasable sabot for a subcaliber projectile. A relatively large danger zone exists for troops in which they can be injured by sabot splinters during the firing of subcaliber projectiles, with the releasable sabots, from a helically grooved weapon barrel, and in order to minimize this danger zone, the sabot of this invention is of a one piece plastic material construction and includes longitudinal slots and cooperative fracture point locations, wherein the longitudinal slots extend continuously from the sabot front end to the gastight region of the driving band, with the longitudinal slots, in cross section, having enlargements in the slot base regions.

  • Patent number: 5388523
    Abstract: In subcaliber projectiles at discharge, a sabot is located between the inner wall surface of the cannon and the fin-stabilized projectile, wherein the sabot, which in a known manner serves to increase the acceleration area, is comprised of a sabot body and a sabot jacket, wherein, in order that upon exit of the projectile from the weapon barrel, the sabot can readily detach itself from the subcaliber projectile, the sabot is segmented, with the contact areas between segments on one side and between the subcaliber projectile and segments on the other side leading to sealing problems, which are overcome, in accordance with this invention, via a special segmentation of the sabot body, with longitudinal slots which include at least, in part, a T-shaped cross section, and reference fracture locations in the region of its inner diameter as well as a gas-tight seal with a concave shaped forwardly-widening seal bonnet having a closing seal.
