Definitions

  • the invention relates to an armor-piercing projectile according to the preamble of patent claim 1.
  • a projectile of the aforementioned type is known from DE-P5 11 58 871. It has a rear main part of the projectile made of hard metal, which is connected to a soft cast brass layer in the ogival tip region.
  • the cast brass layer has a ring-shaped body made of hard metal on the front, the front edge of which lies on the circumference of the floor and delimits a flat end face of the missile. This end face is preferably provided with a ballistic hood. When hitting an armored target surface very flat, the front edge of the annular hard metal body should penetrate into the target surface without damaging the tip of the main body part.
  • the projectile Due to the friction between the ring-shaped hard metal body and the target surface, the projectile becomes larger Angle rotated with the target surface so that it can penetrate them more easily.
  • the cast brass layer is provided between the tip of the main body part and the annular body, the impact impact can already lead to the destruction of the main body part.
  • Another risk of breakage for the main part of the projectile arises from the transmission of the torque, so that the effect of the main part of the projectile is already consumed on the outermost plate when the multi-plate target is used.
  • the front edge of the annular hard metal body must also be arranged with a sufficient radial distance from the longitudinal axis of the projectile, which disadvantageously leads to a large missile diameter.
  • the invention has for its object to provide a projectile of the type mentioned, which is sufficiently effective when striking flat against a multi-layer target of different design.
  • a front area 14 of a main projectile part 12 of a sub-caliber flight projectile 10 includes on the front side Front part 18 with a tip area 20 and a rear area 22.
  • the former is provided with a ballistic hood 66, while a predetermined breaking point 90 to be explained in more detail is arranged in the border region between the latter and the front region 14.
  • the tip region 20 is delimited on the rear by a peripheral edge 24, to which an edge 44 is adjoined by a first surface 34 which is inclined in the firing direction 5 against the longitudinal axis A and which surrounds it as a truncated cone.
  • the edge 44 delimits a second surface 36 in the weft direction S more than the surface 34 inclined towards the projectile longitudinal axis A, which also encompasses the projectile longitudinal axis A as a truncated cone.
  • the surface 36 is delimited on the front by an edge 46.
  • a third surface 38 which is more inclined in the weft direction S than the surface 36 against the longitudinal axis A of the projectile, extends between the rear edge 46 and a front edge 48. This delimits on the rear side a further, more inclined than the surface 38 in the weft direction S against the longitudinal axis A of the projectile Surface 40 which extends on the front side to an edge 42 which encircles the longitudinal axis of the projectile in a circle.
  • the latter includes a flat front surface 42 on which the longitudinal axis A of the floor is perpendicular.
  • a circular cylindrical part 26 extends between the front edge 24 and a rear annular surface 28.
  • the ballistic hood 66 with a wall 68 covers the tip region 20 of the front part 18, a cap 70 extending from an outer edge 74 to a rear annular surface 72, whose clear diameter is adapted to the outer diameter of the circular cylindrical part 26.
  • the ballistic hood 66 is arranged in such a way that the two circular ring surfaces 28 and 72 are adjacent to one another and are firmly connected to one another, for example by means of soldering or another joining method.
  • a circular cylindrical circumferential surface 30 extends continuously to the outer edge 74.
  • the circular cylindrical part 2b can also be provided with an external thread, not shown, which corresponds to an internal thread, also not shown, in the cap 70.
  • the surfaces 34, 36, 38 and 40 in the tip region 20 of the front part 18 form a device G. This has the task, when the flying bullet hits the target surface 82 (see FIG. 3) with its respective surface 34, 36 involved, 38 or 40 to serve as a friction-reducing sliding aid.
  • the latter can be provided with a lubricant L.
  • a lubricant L for example, there are: graphite, molybdenum disulfide, glass and lead, and other low-melting metals.
  • a plurality of lubricants L can also be provided, a corresponding layer being applied to the surfaces 34, 36, 38 and 40 and / or an interior 80 of the ballistic hood 66 being filled with the lubricant L.
  • both glass and lead or another metal can be in powder form and the arrangement mentioned with a thread in the cap 70 and on the circular cylindrical part 26 can prove to be particularly advantageous.
  • the front part 18 is equipped in its tip region 20 with a rotatably mounted ball 52, which is provided as a device R for reducing friction.
  • a hollow spherical surface 58 is formed in the front part 18 as a ball socket 56.
  • the hollow spherical surface 58 is delimited on the front by an annular surface 60, up to which a circular cylindrical part 62 of the front part 18 extends from a rear annular surface 64.
  • the ballistic hood 66 has an area 78 of contact with the spherical surface 54 on its inner surface 76 of the wall 68 which encloses the interior 80.
  • connection of the ballistic hood 66 to the front part 18 is realized analogously to that described in the first exemplary embodiment according to FIG. 1.
  • the friction-reducing lubricant L is advantageously arranged in a region, not shown and designated, between the hollow spherical surface 58 of the ball socket 56 and the spherical surface 54.
  • the mode of operation of the invention is described below with reference to FIG. 3.
  • the missile 10 (its ballistic hood is not shown for reasons of clarity) has approached an armored target 81 shown in detail on a trajectory not shown and touches the target surface 82 with the device G (or R) in an impact area Z.
  • the track the target surface 82 in the plane of the drawing includes with the longitudinal axis A an acute angle, not specified. Thanks to the friction-reducing sliding effect of the device G (or R), the tip region 20 of the front part 18 is deflected from the target surface 82 in the direction of an arrow 84 pointing away from the target surface 82.
  • the rear area 22 of the front part 18 is pivoted in the direction of an arrow 86 opposite the arrow 84 against the target surface 82.
  • the predetermined breaking point 90 is designed such that a substantial part of the pulse rotating in the direction of arrow 86 is effective via the front part 14 on the projectile main part 12, so that the latter rotates against the target surface 82 and the projectile longitudinal axis A with the track of the target surface 82 now includes an angle that is greater than that at the moment the device G (or R) touches the target surface 82. As a result, comparatively much better penetration conditions are advantageously created for the main projectile part 12.
  • the projectile main part 12 breaks as a result of a hard impact impact and thereby loses considerable effectiveness. Since the used front part 18 also moves away from the impact area Z in the direction of an arrow 88, it cannot interfere with the penetration process of the main projectile part 12.
  • a stabilizing tail 32 arranged in the rear area 16 of the main projectile part 12 is advantageously detachably arranged, which is already the subject of an older patent application by the applicant, so as not to impair the penetration effect of the main projectile body 12.
  • a front flat end face 15 of the front region 14 of the main projectile part 12 and a likewise flat rear surface 23 of the rear region 22 of the front part 18 form a butt joint forming the predetermined breaking point 90.
  • a connection between the two surfaces 15 and 23 is formed in such a way that as large a part of the rotating impulse as possible acts on the main projectile part 12 in the course of the breaking process.
  • An edge region delimiting the surface 15 on the circumference advantageously has a sharp, tough-hard bite edge 92 in each case in order to achieve a greater target effectiveness.
  • the predetermined breaking point 90 is realized by a targeted structural weakening.
  • material radiation for example neutron radiation
  • the predetermined breaking point 90 can also be realized by joining in such a way that the front part 18 is connected to the front area 14 of the main projectile part 12 via the surfaces 15 and 23 which have just been formed, in a predeterminable manner.
  • a pulse deflecting against the target surface 82 is sufficiently effective on the front region 14 of the main projectile part 12: between the longitudinal axis of the latter and the target surface 82 there should be a angles which favor the intended penetration process can be achieved.
  • An example of a design of the predetermined breaking point 90 adapted to the latter requirement is shown in dashed lines in FIG.
  • the surface 23 has a convex region 23 ', with which it is connected via an annular surface 23 ".
  • the counter surface with a recess 15' and 151 ' is adapted accordingly.
