Definitions

  • the invention relates to a sabot-missile arrangement according to the preamble of claim 1.
  • Such a projectile is no longer suitable due to its large inflow cross-section for the elongated trajectories sought today, particularly when fighting at high speed and at low altitude.
  • the invention has for its object to develop and train a substantially generic projectile in such a way that it is suitable for use in high-speed devices to combat said targets.
  • the object is achieved by the teaching according to claim 1 with the inventive features specified in its characterizing part.
  • a conical, rotationally symmetrical missile 10.1 with a large length / diameter ratio is arranged in a thin-walled, essentially sleeve-shaped sabot 20.
  • the outer wall of the sabot 20 is essentially circular-cylindrical and (see FIG. 2) has longitudinal slots 50 and 52 so that it is profiled; form the missile 10.1 surrounding elements.
  • brackets 40 projecting radially inwards, in the area of a missile center of gravity 18 of the peripheral surface 14 of the missile 10.1 in a holding area 41 and form a centering on the front.
  • a rear centering is provided in the area of the rear missile part 16 by a central pin 32 which engages on the rear side in a cavity 17 of the missile 10.1.
  • the sabot 20 is bounded on the rear by a rear surface 54, in the vicinity of which the peripheral surface 28 has a radially deformable band-shaped element 68.
  • Radially compressible elements 66 are also arranged in the area of the brackets and can be connected to form a band for better handling.
  • the brackets 40 are provided with relatively small inflow surfaces 46 which are inclined inwards against the longitudinal axis A of the floor and which form the part of an air pocket 48 but at the same time passages (not specified in more detail) into a storage space 49 which extends between the peripheral surface 14 and the inner surface 30 .
  • a front part 10.10 of the flight floor 10.1 is high dense material, preferably thanks to a high proportion of tungsten, which is followed by a rear part 10.11 of comparatively lower apparent density. In this way, the center of gravity of the missile 18 lies sufficiently far in front of an air attack point (not shown) in the acceleration direction S. With the exception of an inside arrangement in the rear area 10.21, the missile 10.2 according to FIG. 3 differs from that according to FIG.
  • a cross-section not shown largely corresponds to that according to FIG. 2 or FIG. 4, has an opening 59 on the back with an internal thread, the inside diameter of which is larger than the largest diameter D of the missile 10.3.
  • Centering surfaces 36 assigned to the sabot 24 are parts of a conical jacket and lie in the holding area 41 in a manner corresponding to the outer surface 14 of the missile. In this way, a double axial fixation of the flight floor 10.30 is guaranteed.
  • a screw-in part 60 with an external thread 62 has a circular-shaped receptacle on the front side, not specified, for a rear surface, not specified, of the missile 10.3 and is delimited on the rear side by a rear surface 58.
  • a thread circle shown in the rear surface 58 is covered by a compressible element 68, which extends on the front beyond the centering and fixing area 36 and thus for one if necessary stretches and thus provides for a seal that may be required and for a sufficient radial contact pressure.
  • the radially compressible elements 66 which are assigned to the holding area 41 on the front side, can, as already described in connection with the first exemplary embodiment, be connected to one another and formed in such a band-like manner.
  • a front cone surface 76 on each of the drive cages shown facilitates the axial insertion of the respective arrangement in the starting position in a high-acceleration device.
  • the materials of the respective sabot are adapted in such a way that, with as little dead load as possible, acceleration-related pressure forces exerted by the respective missile can be safely absorbed. If the arrangement according to the invention leaves the high-acceleration device in question, the interior 49 is already filled with air in such a way that the elements formed by the longitudinal slots 50 and 52 from the drive cage are pivoted in a lever-like manner in the direction of arrows K under the action of the air now flowing in from outside.
  • a region 37 of the sabot 34 of the sabot 24 advantageously proves to be a predetermined breaking point in such a way that the missile 10.3 can continue its movement in the S direction unhindered.
  • a smooth outer surface 14 of the missile 10.2 can be realized again, for example by an inertial body, not shown, which can move along the longitudinal axis A of the floor, or with the aid of springs of radially movable filler pieces.
