Definitions

  • the invention relates to an armor-piercing balancing projectile (penetrator) according to the preamble of patent claim 1.
  • a front area has different cores, each provided with a bore, which are connected to one another and as a stack by means of a holding element designed as a stud with a few threads, with a main penetrator adjoining on the rear.
  • predetermined breaking points are arranged in the stud in the joint areas between the cores.
  • the main penetrator can break in an uncontrolled manner. As a result, the energy bound to the mass of the fragments is lost for the further breakthrough work. As a result, the suitability for use against new multiple targets is significantly impaired.
  • the invention has for its object to provide a more effective penetrator and a method for its manufacture.
  • a penetrator 1 with a large length / diameter ratio and high density (for example by using a heavy metal sintered composite material) with a peripheral surface 2 and facing end faces 3 and 4 has a central bore 5 extending along a central longitudinal axis.
  • a holding element 10 with a wire 10 ' is arranged in the central bore 5, in which regions 13 and 15 of different diameters are adjacent to one another. Between circumferential surfaces 14 of the areas 13 and the wall surface 6 there is frictional engagement due to the shrink fit.
  • the respective ends 11, 12 of the stud bolts 17 and 18 forming the holding element 10 are also shrunk into the penetrator.
  • a transition 14 'between the areas 13 and 15 is rounded.
  • the areas 15 are surrounded by cavities 16.
  • a holding element 10 is formed by a plurality of wires 10 '.
  • the wires 10 ' are spaced apart from one another by a layer 13', the peripheral region 14 of which is provided for the frictional connection with the wall surface 6 of the central bore 5.
  • the wires 10 ' can be twisted.
  • a holding element 30 is formed as a rope made of twisted wires 31. Between the peripheral surfaces 14 'of the wires 31 and the wall surface 6 of the bore 5 there is frictional connection. The non-positive zones extend along screw bands which delimit regions 16 'from one another.
  • the penetrator 1 is heated and the inside diameter of the central bore 5 increases from an initial value d to d 1 .
  • the holding element 10 with a largest outside diameter D is now introduced into the central bore 5, positioned, and the penetrator 1 is cooled again.
  • the outer diameter D fulfills the condition d 0 ⁇ D ⁇ d 1 , so that when the initial temperature is reached due to shrinkage between the surface regions 14 and the wall surface 6, frictional connection is achieved.
  • a bundle of wires 31 is introduced into the central bore 5, the ends of which protrude on both sides beyond the end faces of the penetrator 1, not shown.
  • the wire bundle fills the entire cross section of the hole. Both ends are now pulled apart, the wires 31 are stretched and twisted at the same time.
  • a bundle cross section which is reduced as a result of constriction of the wires 31 increases as a result of the twisting.
  • the penetrator 1 is cooled and the holding element 30 is shrunk in, so that mutual adhesion occurs. As soon as the penetrator 1 has reached its initial temperature again, in addition to the radially acting surface pressure, one of these superimposed axial tension components remains in the adhesion areas.
  • a penetrator according to the invention has significant advantages over one with a sleeve as a holding element, for example made of steel: with regard to a thread or the like required for the circumference for the axial positive locking with a sabot, the sleeve must have a sufficient wall thickness, which disadvantageously means that medium density is significantly affected.
  • a holding element with a comparatively substantially smaller volume is realized in the arrangement according to the invention. Since this is also arranged inside the cross-section, the target material is always exposed to a sharp-edged edge of the dense composite material.
  • the holding element can have a stud at at least one of its two ends, which is also shrunk in and protrudes with a free end, which has a thread, over a respective end face 3 or 4 of the penetrator 1. It can therefore be used to connect a pre-penetrator or to accommodate a rear-side support for a stabilizing tail unit via the thread 19 or 20.
  • the layer 13 '(Fig. 2) can consist of ductile and thus shock-absorbing material of sufficient strength.
  • copper alloys are suitable, for example, which also ensure sufficient friction with the penetrator material under the existing mutual adhesion.
