Definitions

  • the invention relates to a wing-stabilized balancing projectile (penetrator) according to the preamble of patent claim 1.
  • Such a projectile is known from US Pat. No. 4,098,194. It has a core made of a tungsten alloy steel in a cylindrical aluminum body. In the tubular aluminum body there are recesses for releasable axial positive locking with a sabot arrangement. A rear part of the floor is designed as a support for the stabilizing tail.
  • bullets made of heavy metal sintered alloys, preferably based on tungsten, have been proposed.
  • the largest possible penetrator mass and thus the largest possible amount of energy should still be available after penetration of pre-armor and before striking a main armor arranged behind it.
  • the object of the invention is to have the mass of the rear part of the penetrator, which is designed as a tail boom, still available for further penetration after the pre-armor has been penetrated.
  • the invention achieves a double effect: the detachment of the tail unit from the penetrator not only prevents a loss of mass, which would occur when the penetrator part in question was torn off, but also a loss of speed, which would occur if the tail unit remained connected to the penetrator with undesired enlargement of the penetration channel participate in the target passage.
  • the invention advantageously results in an increase in output in the range of up to 15%.
  • a penetrator 1 has a rear part 6 of circular cross section with a peripheral region 8 and a rear surface 9.
  • the rear part 6 is designed as a support for a stabilizing tail unit 10.
  • Fins 12 of the tail unit 10 which extend radially outwards and parallel to the central longitudinal axis A, are connected in one piece with a thin tubular sleeve 14; whose inside diameter is adapted to the outside diameter of the part 6 for fastening the sleeve 14 in the peripheral region 8 by soldering or gluing.
  • the mechanical strength of the fastening is essentially adapted exclusively to the launch acceleration.
  • the parts 12 and 14 of the tail unit 10 are made very thin-walled, in order to represent not only a low drag coefficient but also the lowest possible dead load. The latter is defined here as the mass, which is not involved in the breakthrough and therefore should not exceed a function-related minimum dimension.
  • the tail unit 10 Because of the behavior of the tail unit 10 when it hits the target, it also does not constitute a braking obstacle. This would be the case if the fastening did not take sufficient account of the braking forces when striking the target, especially since the entire rear part 6 can often even be torn off, the mass of which is disadvantageously lost for the penetration.
  • the second exemplary embodiment according to FIG. 2 differs from that according to FIG. 1 by an arrangement of the tail unit 10, in which the sleeve 14 protrudes beyond the rear surface 9 and thus forms an only indicated receptacle 22 for a tracer or the like 24.
  • the peripheral region 8 of the rear part 6 of the penetrator 1 has an axially parallel groove 4 with an axially parallel groove base 4 ′ for each fin 12.
  • the fin 12 is inserted into the groove 4 in such a way that a boundary surface 13 is immediately adjacent to the groove base 4 'and is then fastened in the peripheral region 8 of the rear part 6 by soldering or gluing.
  • the soldered or adhesive connection is designed so that it can withstand the forces that occur during the launch acceleration resists and is lifted at the latest when the fin 12 contacts each other with target material.
  • each fin 12 of the tail unit 10 has an essentially triangular part 16 which is adapted to a groove 4 in the peripheral region 8 for attachment by gluing or soldering.
  • a groove base has a surface 5 inclined in the weft direction S against the longitudinal axis A of the penetration, to which a surface 7 adjoins in the weft direction S with respect to the longitudinal axis A of the penetrator comparatively flat to the peripheral surface of the penetrator 1.
  • the surface 5 (7) of the groove 4 corresponds to a surface 18 (20) on the part 16 of the fin 12.
  • the surface 5 fulfills a supporting function when firing, while the surface 7 acts as a deflector surface when it hits the target.
  • Via a surface 13 of the fin 12 facing the circumferential surface of the rear part 6 of the penetrator 1, the latter can be additionally fastened to the rear part 6 of the penetrator 1, for example in the region of the rear surface 9 or at a point 11.
  • the surface 5 of the groove 4 loses its supporting function in that the fin 12 moves further in the direction of the arrow S due to its inertia. This removes the attachment, the surface 18 moves away from the surface 5, and the surface 20 starts moving at high speed along the surface 7 and moves away from the rear part 6 with a radial and axial component of movement, so that the latter is unimpeded can participate in the breakthrough.
