Definitions

the invention relates to a dropable sabot for a sub-caliber floor according to the preamble of claim 1.
Sub-caliber projectiles also known as sabot or sabot projectiles
sabot or sabot projectiles are fired in particular with automatic weapons with swirl tubes, the sabotable sabots required for this purpose being known, for example, from EP-A-0 288 721.
This known sabot consists of a sabot rear, preferably made of light metal, in which the projectile body or penetrator is anchored, and a sabot jacket, preferably made of plastic, which surrounds the projectile body. At least partially, longitudinal grooves and interacting predetermined breaking points are present on both parts in order to achieve a segmentation of the formed retaining tabs of the sabot rear and the relatively large casing segments when the sabot is detached from the projectile outlet when exiting the pipe muzzle.
the rest of the light metal tail remains whole and flies a considerable distance further in the direction of the projectile body than the previously mentioned segment parts. Due to their mass, these fragments have such a high energy that it is not permissible to overshoot the troop and this results in a relatively large danger zone.
the object to be achieved by the present invention is to create a droppable sabot, with which a drastic reduction in the danger zone for the troops is achieved.
a sub-caliber or sabot projectile is only partially shown and contains a projectile body 1, preferably made of heavy metal, with a ballistic hood 2 attached to it, and a one-piece, removable plastic sabot 10 according to the invention, see also FIG has a sabot jacket 11 and a sabot rear end 12.
a sabot jacket 11 On the sabot 10 there are longitudinal grooves 13, regularly distributed around the circumference and continuously from the front (in the drawing from above) to the gas sealing area 14a at the end of a guide band 14, which have cross sections in the groove base area 15.
This forms segments 20 which are connected to one another by corresponding predetermined breaking points 16, for example six each according to FIG.
further grooves 21 are preferably provided on the sabot rear 12 to form further predetermined breaking points.
the sabot 10 has a circumferential groove 17 at the front or, on the circumference of the sabot rear 12, fastening means 18 for the protective hood or cartridge case, which is not shown, but is known per se, and the projectile body 1 is in the sabot 10, for example by grooves or grooves 19 attached.
the sabot 10 is made of fiber reinforced plastic, e.g. made of PEI, PEEK or PPS with glass, carbon and / or Armid fibers, whereby a mixed form of different fibers is also possible.
