Definitions

  • the invention relates to a penetrator according to the preamble of patent claim 1.
  • a penetrator of the aforementioned type is the subject of the patent (patent application P 27 43 732.7-15). This is very suitable for penetrating multiple targets (bulkhead armor).
  • the puncture performance on a heavy single target or a multiple target with a particularly strong pre-armor - under the same impact conditions - is comparatively lower than that of a monobloc penetrator, which in turn shows a comparatively higher penetration performance on the heavy single target or the multiple target with a particularly strong pre-armor.
  • the object of the invention is to provide such a penetrator.
  • a pre-penetrator 10 to which a main penetrator 80 is arranged axially, has three core elements 12, 30 and 50 arranged one behind the other along a longitudinal axis A of the projectile.
  • the tip-side core element 12 is provided with a front surface 14 which delimits a spherical cap.
  • a conical outer surface 16 Connected to them on the back is a conical outer surface 16 which has a common peripheral edge 18 with a circular cylindrical surface 20.
  • the circular cylinder surface 20 is followed on the rear by a rounding 22 which merges into a circular funnel area 24 with a central rounding 26.
  • a front surface 32 of a second core element 30 has a circular cone jacket region 34 with a central rounding 36 and is delimited by a groove 38 which extends radially to the circumference with a circumferential circular edge 40.
  • a circular cylinder part with a circumferential surface 42 connects to the rear of the latter. This is delimited on the back by a rounding 44, which, together with a circular funnel area 46 with a central rounding 48, forms a rear side surface, not specified.
  • a third core element 50 has a front surface 52 with a circular cone jacket region 54 and a central rounding 56. The front surface 52 is adjoined by a circular-conical transition region 58 with a groove 60 delimiting it around the circumference, which is delimited on the circumference by a circular edge 62.
  • a front part 82 of a main penetrator 80 is delimited by a front surface 84 with a circular cone region 86, a central fillet 88 and a circular edge 90.
  • the latter delimits a circular-cylindrical transition region 92 on the front with an adjoining groove 94 ending in a circumferential circular edge 96.
  • the sleeve 110 extends with a circumferential surface 112 up to an external thread 116 on an unspecified sleeve front part of lesser wall thickness.
  • An inner surface 113 of the sheath 110 closely surrounds the core elements 30 and 50 and the front part 82.
  • a back cover (not specified in more detail) with an internal thread of a ballistic hood 118 serves to releasably fasten the latter to the sheath 110, an inner surface 119 of the ballistic hood 118 being tight bears against the conical outer surface 16 of the core element 12 and this in the axial direction with its rear sides - against the front surface 32 of the core element 30 which is adapted to its central region, this with its rear sides - against the front surface 52 of the core element 50 which is adapted to its central region and this finally with its Backside - presses against the front surface 84 of the front part 82 which is adapted to its central area.
  • the joint areas 1, 2 and 3 are, in order, between the inner surface 113 of the casing 10 and the rounding 22 and the groove 38, the rounding 44 and the groove 62 and finally the rounding 66 and the groove 54 are assigned an annular cavity 120, 122 or 124 in question.
  • the core elements 12, 30 and 70, with each other and with the front part 82 having the same outside diameter, as well as the main penetrator 80 and the sleeve 110 are made of a metallic material of high density, for example a sintered alloy with a high proportion of tungsten.
  • the ballistic hood 118 is made of steel.
  • a pre-penetrator 10 to which a main penetrator 190 is axially arranged, in turn has three core elements 130, 150 and 180 arranged one behind the other along the longitudinal axis A of the floor.
  • Core element 130 with a front surface 132, which delimits a spherical cap, has a circular cone-shaped circumferential surface 134, which meets a circular cylindrical surface 138 in a rear circular edge 136.
  • the latter extends up to a circular rear edge 140 which delimits a circular funnel surface 142 on the circumference. This extends up to a circular edge 144 of a central blind hole 146 with an inner surface 148.
  • the tip-side core element 130 is followed by the second core element 150 with a front circular conical surface 150, which extends from a circumferential circular edge 154 to a front circular edge 156 of a central axial one Passage 166 extends.
  • a circular cylindrical peripheral surface 158 extends from the front circular edge 154 to a rear circular edge 160 which delimits a circular funnel surface 162 on the peripheral side. The latter extends up to a rear circular edge 164 of the passage L66 with an inner surface 168.
  • the second core element L50 is followed by the third core element 170 with a front circular cone surface 172 which extends from a circumferential circular edge 174 to a front circular edge 176 of a passage 186 an inner surface 188.
  • a circular cylindrical circumferential surface 178 is delimited on the front by the circular edge 174 and on the rear by a rear edge 180, in which the circumferential surface 178 collides with a circular funnel surface 182 which extends up to a rear circular edge 184 of the passage 186.
  • the third core element 170 is adjoined on the rear by a front part 192 of the main penetrator 190 which has a circular cylindrical peripheral surface 194.
  • the circumferential surface 194 is delimited on the front by a circular edge 196, which is followed by a circular truncated cone 198.
  • the peripheral surface 194 terminates in a fillet 208 with an outer circular edge 210 of a peripheral surface 214 with a thread 216 of the main part 212 of the main penetrator 190.
  • the mandrel 202 passes through the passages 186 and 166 of the two core elements 170 and 150 and extends with its free one End 206 in the blind hole 146 of the core element 130.
  • the sleeve 10 and the ballistic hood 118 are designed analogously to FIG. 1, the rear surface 114 being adapted to the fillet 208 and the circumferential surface 112 having the same outside diameter as that of the main part 212.
  • the core elements 130 and 150, 150 and 170 are pressed axially against one another and the core element 170 is pressed against the front part 192.
  • the inner surfaces 188 and 168 of the passages 186 and 166 and the inner surface 148 of the blind hole 146 closely enclose the mandrel 202.
  • the penetration is improved in the manner described.
  • the process described is repeated at least on each thick plate.
  • the core elements of the pre-penetrator 10 can be adapted in terms of their number, the material and their length and thus also the respective mass of a respective target plate number.
  • the described deflection of the respective core element of the pre-penetrator 10 designed according to the invention results in an enlargement of the entry opening in relation to the penetrator diameter in the relevant target plate.
  • This proves to be advantageous for the subsequent penetrator part - especially with novel targets, for example with glass and / or ceramic modules: it promotes its passage through the relevant plate and thus improves its effect against downstream target plates.
