Definitions

  • the invention relates to a fragmentation body for grenades, in particular hand grenades, consisting of a hollow body, the wall of which consists of metal particles embedded in plastic and which has a different shape from the spherical shape, in the axis of which the fragmentation body has at least one opening, the wall of the splinter body has an axially symmetrical thickening with an increased accumulation of metal particles compared to the adjacent wall regions of the splinter body
  • the spherical shape of the splinter body with a detonator arranged in the center of the ball would in itself be ideal.
  • the detonation wave emanating from the detonator reaches all points of the inner spherical surface of the splinter body at the same moment, so that the entire splinter shell is also disassembled at the same time - especially with hand grenades - for reasons of dimensioning.
  • the required number of fragments and the amount of explosives required would result in a relatively large ball as a splinter body, the handiness of such a hand grenade would be impaired however, the splinter distribution is irregular, ie in different directions based on the three-dimensional axis system of the hand grenade.
  • Splinter bodies for hand grenades have become known which have an inward thickening approximately in the central region or somewhat above the middle of the side wall, as a result of which the interior of the hand grenade is divided into two subspaces, a usually smaller upper and a larger lower one (AT- A-357 90 4 , AT-A-368 280).
  • This measure was intended to influence the propagation of the detonation wave inside the hand grenade in the sense of a uniform spreading of the fragments or metal particles.
  • this effect has not shown sufficient effect in practice.
  • the thickening of the wall of the splinter body is formed in the transition region between the bottom surface and the side surface, and / or between the shoulder surface and the side surface
  • the bottom surface is the inner surface of the splinter body opposite the opening for the igniter.
  • the shoulder surface is the inner surface of the splinter body surrounding the opening for the igniter
  • the thickening of the wall of the splinter body according to the invention is advantageously directed into the interior of the hand grenade, in the form of an inward curvature of the inner wall, since an outward thickening would have a rather unfavorable effect on the outer shape of the hand grenade.
  • an increased accumulation of metal particles in the wall of the splinter body in the transition region between the bottom surface and the side surface of the splinter body is important, because a noticeable defect in splinter penetration was perceived in the splinter scattering sector corresponding to this region.
  • a similar fragmentation defect can also occur in the fragmentation sector assigned to the wall area of the fragment body between the shoulder surface and the side surface.
  • the measure according to the invention is particularly effective in the case of a grenade or hand grenade in which the detonator or detonator center is at least approximately in the region of the center of the splinter body, but above all for a detonator which extends along the axis of the splinter body and with Distance above the lower thickening or (if there is also an upper thickening) ends at a distance below the upper thickening of the splinter body
  • the invention is explained in more detail with reference to the drawing using an exemplary embodiment.
  • the drawing shows a hand grenade, partly in vertical section
  • the hand grenade shown in the drawing has a hand grenade body 1, which consists of an inner fragment body 2 designed as a hollow body and an outer housing shell 3.
  • the outer housing shell 3 is made of tough-elastic plastic, for example polyethylene, and has a neck-shaped extension 4 with an external thread .
  • the wall of the splinter body 2 consists of metal particles embedded in plastic in the form of steel balls. The metal particles are arranged in a tight packing.
  • the plastic connecting the metal particles can be made of polystyrene, for example.
  • a detonator head 5 is screwed onto the hand grenade body and carries the usual functional elements, such as bats, safety clips and detonator tubes 6.
  • the wall of the splinter body 2 has an axially symmetrical thickening 10 in the form of an inward bulge in the transition region between the bottom surface 8 and the side surface 9. In this thickening 10 there is an increased accumulation of metal particles compared to the adjacent wall areas of the splinter body 2.
  • an axially symmetrical thickening 11 in the form of an inward bulge may also be present in the transition region between the shoulder surface 12 and the side surface 9 of the splinter body.
  • the drawing also shows a spherical surface K which is concentric with the center M of the splinter body
  • the axis of the spherical surface K which coincides with the axis A of the splinter body and points from the center M in the direction of the igniter opening is defined as its zero degree axis.
  • the thickening 10 of the wall of the splinter body is in the illustrated embodiment between the spherical sectors S, 135 ° and S 2 of 160 °.
  • the possible upper thickening 11 of the wall of the splinter body is between the spherical sector S 3 of 20 ° and S4 of 45 °.
  • the center point M of the splinter body is the bisection point of the axial extent (external dimension) of the splitter body 2.
  • the detonator 13 which is arranged in the lower part of the ignition tube 6 and consists, for example, of four partial charges, is arranged such that its center is at the center M of the fragment body.
  • the detonator extending in the direction of the axis A of the splinter body ends at a distance above the thickening 10 and above at a distance below the thickening 11 (if there is one).
  • the illustrated embodiment shows an essentially egg-shaped splinter body.
  • the measure according to the invention can advantageously but also in other "stretched" forms of fragmentation shell Einset - zen, such as Splitterkörpem in the form of an ellipsoid, a cylinder, possibly with up and molded bottom cone or hemispheres, etc..
  • the invention is also not limited to hand grenades, although it is of particular importance in this area of application
