Definitions

  • the invention relates to a fragmentary projectile according to the preamble of the claim 1.
  • an explosive projectile in which the outside and at least one layer of preformed splinter bodies in a recess in the casing are arranged.
  • the fragments arranged at the back of the igniter are replaced by the intermediate charge radially accelerated, with a front, thick-walled section for attachment of the detonator can act as an inhibitor to the spread of the splinters.
  • the invention has for its object to propose a shell for a fragmentary projectile, which has a large splintering effect when the splinters are arranged in the front area of the envelope has the greatest possible forward effect in the direction of flight owns and with delayed ignition the breakdown of a concrete component enables.
  • the splintering effect after the breakthrough of the concrete component to be guaranteed.
  • the invention enables high splinter speeds in which the wall, is minimized so far in particular in the front projectile envelope area that by Stiffening ribs / webs or by another support still one there is sufficient structural strength to the penetration ability of the fragmentary floor to ensure penetration of concrete parts such as concrete ceilings.
  • the window can be ring-shaped or divided by rungs or ribs or can be provided several times in succession in the splinter casing in the axial direction.
  • the window itself is formed by a considerable weakening of the material of the splinter casing, the outer contour of the splinter casing not being impaired by the formation of the window, ie there are no features recognizable on the outer contour that indicate the formation of a window. Gaps or steps on the outer contour are therefore omitted, so that no notch effect of the splinter casing is provoked.
  • the arrangement of the window in the front area of the projectile shell in connection with the initiation of the explosive charge on the rear or the bottom providing a high level of directionality and speed of the splinters to the front . Due to the initiation of the explosive charge on the bottom side, the detonation wave or the detonation front runs from the bottom side forward through the projectile and results in a particularly small radiation angle of the fragments in relation to the longitudinal axis of the fragmentary storey.
  • a shell 1 has a not shown Splinter floor in its front area differently structured sections namely on a thick-walled section 2 for receiving a not shown detonator or a floor hood also not shown in a thread 3, a thin-walled section 4, a section 5 with increasing Thickness and a section 6 with the usual thickness of a known projectile casing according to DE 38 04 351 A1.
  • the section 4 is formed by an inner recess 7, the outer contour 8 remains unchanged.
  • the thickness 9 of the shell in section 4 is a few millimeters. Starting from this thickness 9, this thickness then increases in the direction of the arrow 10 continuously until the beginning of section 6.
  • a support body 12 is screwed into a recess 11 against the direction of the arrow 10.
  • the support body 12 consists of a hollow pin 13 with a thread 14, a central tube 15 and four stiffening ribs 16 with intermediate, segment-shaped free spaces 17 for receiving fragments 21 from construction splinters 18.
  • the stiffening ribs 16 support the thin wall 19 in the section 4.
  • the thickness 9 of the wall 19 is a fraction of the thickness 20 of the shell 1 in section 6.
  • the decisive factor for the thickness 9 is the penetration to be guaranteed of a concrete target. Depending on the projectile caliber, it can be 30 to 70% the thickness be 20.
  • a support effect also comes from between the stiffening ribs 16 arranged splitter packs 21.
  • the splinter packs 21 extend in the longitudinal direction between the levels 30, 31 according to a section 29
  • the splitter packs 21 can also be dash-dotted drawn, drawn round contour 32.
  • the construction splinters 18 are designed as spheres, cubes, ellipsoids and embedded in a filler material 24, which is the shock wave impedance or largely the shock wave impedance of the construction splitter 18. This leads to, in conjunction with the measures described above to a large kinetic Energy of the constructional fragments 18 upon detonation of the fragmentary floor.
  • the central tube 15 serves to accommodate an ignition path or not shown Ignition cable for a base-side igniter or also for an implied one Explosive charge 33 of a main explosive charge 34.
  • the ignition tube 15 can also be omitted in favor of the volume of the fragments 21.
  • the Ignition point is at or in the area of the floor of the fragmentary floor, one great effect in the direction of flight or towards the ground.
  • the Construction splinters 18 reach a long range, because to break up the Wall 19 in section 29 requires a relatively small amount of deformation work is.
  • the pin 13 is threaded 43 connected to a central tube 44 with flange 45.
  • a ring-shaped fragment package 46 lies around the ignition tube 44 and between walls 47, 48.
  • a splinter shirt 49 made of steel which also bears against the wall 47 covers this Splitter packet 46 on the circumferential side and lies in a shoulder 50 of the flange 45 of the homogeneous splinter package 46 with continuous construction splinters 18 there is a higher number of construction splinters 18 than in the splinter packs 21 within the support body 12 according to FIGS. 1-3.
  • the supporting effect of the wall 19 of the shell 1 is due to the fragment package 46 with the splinter shirt 49 and the flange 45 in front.
  • a fragmentary projectile 51 has a proximity fuse 53 and in the projectile casing 1 one-piece stiffening ribs 52. These extend through sections 4 and 5.
  • the main explosive charge 34 corresponds to the beveled stiffening ribs 52 and an ignition tube 54 through a neck 35 in the shape of a bottle neck.
  • Splinter packs 56 lie between the stiffening ribs 52 and between the levels 30 and a plane 55. Seen radially, the fragment packets 56 are delimited by a thin-walled sleeve 57 between the main explosive charge 34, 35 and the fragments 56 and through the wall 19 and a cone wall 22.
  • An ignition transformer is designated 58 and fills the sleeve 57 in a short section 59. The sleeve 57 is thus only partially filled with explosives 36 by approximately 67%.
  • a much larger explosive charge level of 100% lies with the fragmentary floor 60 with not shown Boder Zünder according to FIGS. 7, 8 before.
  • the Projectile casing 1 is screwed to a projectile hood 61.
  • the main explosive charge 34 extends - bottle-shaped tapered - to level 30. Thereby If the main explosive charge 34 detonates, there is an acceleration of the construction splinters 18 also in the front section 59, see FIG. 5 before. Otherwise corresponds the splitter device of the splitter device described for FIGS. 5, 6.
  • a top detonator can also be used instead of the ground igniter.
  • a fragment packet 76 is plug-shaped, that is to say without a central one Recess or bore formed and with a washer 77 made of steel on the rear side completely covered against the explosive charge 34.
  • the fragment packet 76 lies against one after the penetration of a concrete target easily dismantled or detachable screw-in body 78 and on a wall 79 of the shell 1.
  • the one-piece with the projectile casing 1 ribs 52.1 are embedded in the construction splinters 18.
  • the splinter effect to the front at an angle 80 of approx. 120 ° is due to - without a dead splinter area given a ground igniter used.
  • the screw-in body 78 consists of Carbide or a suitable steel.
  • construction splinters 18 instead of the drawn spherical construction splinters 18 there is also one other shapes of the construction splinters 18 such as cubes, plate shape, possible.
