Definitions

  • the invention relates to an armor-piercing balancing projectile according to the preamble of patent claim 1.
  • a projectile of the type mentioned is known from DE-PS 14 28 679. It has different armor-piercing pre-core elements in an envelope axially one behind the other and an armor-piercing main core element adjoining these on the back. Between the core elements, which consist of hard and / or heavy metal, layers of plastic-bonded hollow spheres or a light metal alloy are provided as shock-absorbing means. By arranging the different pre-core elements, a targeted mass reduction of the projectile arrangement is to be realized in such a way that, after penetration of a pre-armor while protecting the main core element against premature destruction due to shock wave stress against a main armor of the target, a sufficient projectile mass in the form of the main core element is available.
  • missiles of the type mentioned at the outset are exposed to loads acting through multi-plate targets transverse to the longitudinal axis of the projectile, which regularly lead to premature bending of the missile.
  • a penetration channel inclined towards the extension of the projectile trajectory can reach the main core element the main armor and thus affect the effect of the projectile in a very sensitive way.
  • the invention has for its object to provide a projectile of the type mentioned, which is suitable to combat modern multi-plate targets with the greatest possible use of the energy inherent in the projectile.
  • a first exemplary embodiment has a first pre-core element 10 in the tip region and a second pre-core element 20, which is arranged axially downstream of this, to which a main core element 30 is connected on the rear side.
  • a front surface 12 of the pre-core element 10 is designed as a hemispherical surface. It runs on the back into a circular cylindrical peripheral surface 18.

  • a rear surface 26 of the pre-core element 20 is designed as a hollow spherical cap and is delimited in the circumferential area by an annular surface 28 crossing the longitudinal axis A of the projectile.
  • a main core element 30 adjoining on the rear is adapted with its front surface 32 to the rear surface 26 and is delimited in the peripheral region by an annular surface 34 crossing the longitudinal axis A of the projectile.
  • An axial distance, not specified, between the mutually facing circular ring surfaces 28 and 34 is to be assigned to a second intermediate area 42.
  • a sleeve 36 extends axially over the two pre-core elements 10 and 20 and at least one unspecified front area of the main core element 30 and encloses them.
  • a tip element 46 with a hemispherical head 48 is fixed with a circular cylindrical bolt 50 in a central axial bore 52.
  • a second exemplary embodiment differs from that according to FIG. 1 by the formation of a rear side surface 27 of the front core element 20 and a front surface 33 of the main core element 30.
  • the latter is circular-conical and funnel-shaped, the surfaces 27 and 33 touch each other.

  • the pre-core element 20 is adapted with a front hollow spherical surface 22 "of the hemispherical surface 14 'and is delimited in the circumferential area by a circular ring surface 24 crossing the longitudinal axis A of the projectile 27 "limited.
  • An unspecified axial distance between the surfaces 16 "and 24 is to be assigned to a first intermediate region 40.
  • Circular cylindrical area 39 has an external thread 39 'to which it is attached on the back a groove 31 connects.
  • the casing 36 extends from a rear edge 37 in the immediate vicinity of an internal thread, which corresponds to the external thread 39 'and is not designated in any more detail, to the ballistic hood 44.

  • the shell 36 extends with substantially the same wall thickness over the region 10 "of the pre-core element 10 and points in the vicinity of the region 10 'A reinforcement 45 with a circular cylindrical inner surface 45' of smaller inner diameter.
  • the reinforcement 45 can already be assigned to a ballistic hood 44, the tip design of which corresponds to that of the aforementioned exemplary embodiments.
  • the screw connection of the sleeve 36 to the main core element 30 advantageously allows one or both of the pre-core elements 10, 20 to be replaced, for example to adapt to a particular target to be combated.
  • a pre-core element 10 in turn has two circular cylindrical regions 10 ′, 10 ′′ of different diameters.
  • the latter is delimited by a rear surface 14 designed as a hollow spherical cap with a circumferential annular surface 16 that crosses the longitudinal axis A of the floor 14, a hemispherical damping element 54 is fitted on the front side.
  • the damping element 54 has a circular cylindrical receptacle for a front region of the front core element 20 with a circular end face 22 and a circumferential surface 23, which meet in a circular edge 22 ', in a rear surface, which is not designated in any more detail.
  • a pin formed in this way protrudes over an annular surface 24 ', the peripheral region of which is not covered by the damping element 54.
  • An axial distance between the surfaces 16 and 24, like the damping element 54, is to be assigned to a first intermediate region 40 '.
  • the front core element 20 is bounded on the back by a circular funnel surface 27, to which a damping element 56 is adapted.
  • the latter is designed in the shape of a circular funnel with a predetermined wall thickness and is adapted on the back to a circular conical surface 33 of the main core element 30.
  • the damping element 56 is to be assigned to a second intermediate area 42 ′, while a predetermined breaking point 38 formed as a wall weakening of the casing 36 is included in the first intermediate area.
  • the pre-core element 10 has a hemispherical front surface 12 and a central rear surface 14 'which crosses the longitudinal axis A of the projectile.
  • a circular cylindrical surface 15 projects beyond the latter and is delimited in the peripheral region by an annular surface 16 '.
  • a damping element 58 is adapted with a front region of the rear side 14 ', 15, 16' of the front core element 10, which is not specified in any more detail, and is delimited on the rear side by a surface 58 'in the form of a spherical cap, to which an annular surface 60 which crosses the longitudinal axis A of the floor is connected on the circumference .
  • the pre-core element 20 is designed essentially circular-cylindrical, the circular-cylindrical region being delimited by a circular ring surface 24 on the front and a circular ring surface 25 on the rear. Over the former is a spherical cap with a front surface 22 which is adapted to the surface 58 'of the damping layer 58. An axial distance between the circular ring surfaces 60, which is not specified in any more detail and 24 is to be assigned to a first intermediate region 40 '. A hemispherical part with a rear surface 26 'protrudes beyond the rear circular surface 25. With a predetermined axial distance, a front region of the main core element 30 adjoins with a surface 32, formed in mirror image.
  • the damping element 62 is designed on the tip side in accordance with the exemplary embodiments described above.
  • a shell 36 is essentially of the same wall thickness over its entire length
  • the sixth exemplary embodiment differs according to FIG. 6 through a sleeve 36 ', the wall thickness of which increases substantially continuously from a front edge 36 "to an area 37" with the same outside diameter.
  • the sleeve 36' has an external thread 37 for releasable Connection to the ballistic hood 44.
  • the latter is provided in a region 45 with a circular cylindrical inner surface 45 'which extends to an edge 43.
  • a pre-core element 10 has a circular cylindrical region 10 ′ on the front side with a circumferential surface 13 ′ adapted to the inner surface 45 ′.
  • a front surface 12 ° is delimited by a circular edge 13 in which the surfaces 12 ′ and 13 ′ collide.
  • At the back of the area 10 there is an area 10 ′′ frustoconical shape.
  • a pre-core element 20 (like the following pre-core elements 70 ... 80) is also designed as a circular cone frustum. Not abbreviated planar abutting surfaces of the aforementioned pre-core elements are each of the same size.
  • a front annular surface 34 'of area 30 is in close contact with surface 37'.
  • the area 30 ' has an external thread 39' and the sleeve 36 'has the corresponding internal thread, not designated in any more detail.
  • the arrangement described allows, if necessary, a field-like replacement of the pre-core elements 10, 20, 70 ... 80 to adapt to a particular target. There are advantageously no special tools for this required. Since the largest diameter of the pre-core element 10 provides a corresponding penetration area in a pre-armor, the subsequent pre-core elements 20, 70 ... 80 can be effective against numerous armor elements arranged after the pre-armor without significant hindrance. This favors the effectiveness of the main core member 30 against main armor.
  • the threads 37 and 39 ' are assigned to the respective intermediate areas 40 "and 42".
  • an advantageous mass ratio of 1: 12: 6 is particularly to be mentioned, in connection with a corresponding arrangement the first numerical value of the first preliminary core element 10, the second numerical value of the preliminary core element 20 and the third numerical value of the Main core element 30 is assigned.
  • the main core element 30 is preferably made of a high-strength, ductile shear metal alloy, for example a sintered alloy containing a high proportion of tungsten, while the two pre-core elements consist of a corresponding material with lower ductility. However, this can also be done when using damping elements first pre-core element 10 can be made from a ductile heavy metal alloy.
  • the core elements can move in their mutually facing and articulated regions, namely in the intermediate regions 40, 42; 40 ', 42', pivot against each other.
  • the sleeve 36 made of ductile material of sufficient strength, can absorb part of the transverse forces through deformation and ensures the greatest possible frictional connection between the adjacent surfaces of the core elements. This ensures that an axial impact component directed against the target is sufficient Size remains effective.
  • target break point 38 is advantageously only effective when the intermediate area in question gets into a penetration channel on the target side, which results from the effect of pre-core element 10 and is inclined against the projectile flight path in the majority of the cases examined.
  • envelope design according to FIG. 6 can advantageously also be applied to the exemplary embodiments according to FIGS. 1 to 5.
