Definitions

  • the invention relates to an explosive projectile for splinter generation according to the preamble of claim 1.
  • Such an explosive projectile in the form of a spin-stabilized artillery projectile in the caliber 105 mm is known, for example, from the Rheinmetall Weapons Technical Manual, 6th edition, 1983, page 467, image 1102 (or from Rheinmetall Handbook on weaponry, first english edition, 1982, page 509, fig. 1102).
  • such an explosive projectile is used as a multipurpose explosive projectile in the ammunition equipment of the Leopard II main battle tank Goals on.
  • these spin-stabilized or wing-stabilized explosive projectiles are designed to be relatively thick-walled, in particular in the rear area and below the guide band (sealing band).
  • This thick-walledness requires a certain coarse splinter size in this area, the splinter characteristic of the floor and shell, or the thick-walled rear area and thinner front area, being very different.
  • the thick-walled rear area is only broken down into a few, quite large and therefore comparatively slow fragments.
  • the arrangement of the guide or sealing tape which is shifted far back to almost directly to the floor of the floor, results in a significant reduction in the radial pressure load on the rear floor area by the propellant gases when firing from the barrel weapon.
  • the wall thickness in the rear casing and rear area (splinter-active floor) of the explosive projectile can be substantially reduced, which is made possible by the reduction in the sensitivity of the projectile rear area against radial pressurization achieved by means of the measures according to the invention; this makes the entire shell material of the projectile lighter, the number of fragments is standardized and enlarged, and more explosives can also be filled into the projectile.
  • the reference number 10 denotes an explosive projectile which has a projectile casing 12, an explosive mass 14 cast therein and a head detonator 16, e.g. B. has a impact detonator or adjustable detonator.
  • the projectile casing 12 is reinforced in the rear area of the explosive projectile to ensure the firing strength and the wall thickness here, as in the storey floor 18, is approximately twice as large as in the front projectile casing area.
  • a circumferential guide band 20 is arranged from the floor 18 at a distance of approximately the order of a caliber diameter.
  • the width of the guide band 20 is approximately as thick as the wall thickness of the thick-walled projectile shell in this rear area.
  • the problem of firing strength and bullet durability is due to the fact that the sensitivity to radial loads increases with increasing thin-walled casing.
  • the main radial load on the projectile shell arises from the gas pressure of the propellant gases behind the guide band when the explosive projectile is fired from a large-caliber barrel weapon.
  • FIG. 2 shows an exemplary embodiment according to the invention, which shows a swirl-stabilized, full-caliber explosive projectile 30 in which the wall thickness (t) of the projectile shell in the rear projectile area 32 is approximately the same or in the same order of magnitude as the central projectile shell 12.
  • FIG. 1 shows a swirl-stabilized, full-caliber explosive projectile 30 in which the wall thickness (t) of the projectile shell in the rear projectile area 32 is approximately the same or in the same order of magnitude as the central projectile shell 12.
  • the projectile envelope 12 is cylindrical in the rear projectile area up to the transition into the projectile floor 38.
  • the guide band 40 is arranged with its rear gas pressure-absorbing side in close proximity to the transition region from the projectile envelope 12 (or rear projectile region 32) into the projectile floor 40, or very close to a circumferential edge 42 formed thereby.
  • the distance of the guide belt 40 from this circumferential edge 42 is denoted by delta ( ⁇ ) and, according to the invention, should be an amount between 0 and less than or equal to 2 x t: 0 ⁇ ⁇ ⁇ 2 x t (wall thickness t).
  • the guide band 40 can therefore also be arranged at the very back and begin directly at the edge 42.
  • the cylindrical projectile shape extends to the storey floor and the storey floor 38 is dome-shaped (e.g. spherical dome, elliptical dome) to bulge outwards or backwards to increase the pressure resistance results in the rear inclination angle ⁇ at the location of the circumferential edge 42 a value of> than 10 ° between the cylindrical projectile casing 12 (or the inside of the weapon barrel) and a tangent applied to the projectile floor.
  • the preferred range of the rear tilt angle ⁇ is between approximately 20 to 70 °, preferably approximately 30 °.
  • Figure 3 shows a known full-caliber wing-stabilized multi-purpose explosive projectile 50 (z. B. 120 mm MZ DM 12 A1) whose warhead has a thin-walled projectile shell 12, an explosive mass 14 filled therein and a base detonator 52 connected thereto.
  • the same reference numbers have been used for the same components); the same statements apply to the warhead 50 as to the explosive projectile 10 described above.
  • the shell 12 and the floor 18 are here in the rear of the explosive projectile or the warhead 50 also designed to ensure the firing strength about twice as thick as the front shell 12.
  • the warhead has a sealing tape 54 in the rear cylindrical shell area.
  • An almost caliber-sized wing guide 56 is attached to the housing of the ground igniter 52.
  • the warhead 50 assigns for its multi-purpose function Penetration of armor plates a shaped charge insert 58 and a forward ignition tube 62 (standoff) with z. B. means for trigger ignition.
  • the different wall thickness in the cylindrical wall area and in the rear floor area leads to the previously described uneven splinter formation and effect in the target.
  • the explosive projectile 60 (warhead) according to the invention shown in FIG. 4 with sealing tape 66 has a thickness of the wall thickness in the rear floor area 32 of approximately the same order of magnitude as the wall thickness (t) of the casing 12 in the central warhead area.
  • the shell 12 is cylindrical in the rear warhead area 32 up to the transition to the floor 38 and the sealing tape 66 is arranged with its rear gas pressure-absorbing side in close proximity to the transition area of the shell 12 in the floor 38.
  • the distance delta of the sealing band 66 from the peripheral edge 42 in the transition region from the shell 12 into the floor 38 is approximately equal to or less than twice the wall thickness (t) of the shell 12.
  • the sealing band 66 can have a width of at least twice the wall thickness (t ) have the shell 12.
  • the floor 38 of the warhead 60 is characterized, at least in its outer edge region, by the same wall thickness as the floor shell 12 and a dome-shaped bulge towards the outside.
  • the preferred value of the rear angle of inclination Phi on the peripheral edge 42 is approximately 25 ° to 35 °.
  • the shaping and sealing measures according to the invention significantly reduce the sensitivity of the rear shell or warhead shell and the floor of the floor to gas pressure when fired. This enables a considerable reduction in the wall thickness in the rear area to approximately the wall thickness of the shell in the front storey or warhead area. As a result, when the projectile is disassembled, many small high-speed splinters also arise from the rear region thereof, which thus bring about an adjustment of the splinter characteristic between the projectile shell and the rear region of the projectile.
  • splitters-active floor Since at least a considerable part of the floor of the floor is broken down into small fragments during the detonation (splitter-active floor), these splitters are able to cover the rear battle area in the target - viewed in the opposite direction of flight - with splinters.
