Definitions

  • the invention relates to a splinter body for grenades, in particular hand grenades, consisting of a hollow body, the wall of which consists of plastic particles embedded in plastic and which has a different shape from the spherical shape, in the axis of which the splinter 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 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 jacket is also dismantled at the same time.
  • Spherical splinter bodies cannot always be realized in practice, on the one hand for ballistic reasons, and on the other hand - especially in the case of hand grenades - for reasons of dimensioning.
  • Hand grenades for larger fragments and detonation powers are therefore usually not designed with spherical, but rather with egg-shaped or otherwise elongated fragment bodies.
  • the splinter distribution is irregular, ie different in different directions with respect to 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-357 904, 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, that the detonator or the detonator center is at least approximately in the region of the center of the splinter body, and that the thickening of the wall of the splinter body, based on a spherical surface concentric to the center of the splinter body, lies in the region between the spherical sectors of 130 ° and 165 °, preferably 135 ° and 160 °, the zero degree axis coinciding with the axis of the splinter body and pointing to the opening of the splitter body.
  • the bottom surface is the inner surface of the splinter body opposite 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 area between the bottom surface and the side surface of the splinter body is important, because a noticeable deficit of splinter penetration was perceived in the splinter scattering sector corresponding to this area.
  • a similar splinter penetration deficit can also occur in the splinter scattering sector assigned to the wall area of the splinter body between the shoulder surface and the side surface. It may therefore be advantageous if a thickening is also formed in the transition region between the shoulder surface and the side surface, which thickening lies in the region between the spherical sectors of 15 ° and 50 °, preferably of 20 ° and 45 °.
  • the shoulder surface is the inner surface of the splinter body surrounding the opening for the igniter.
  • the detonator is located along the axis of the splinter body extends and ends at a distance above the lower thickening or at a distance below the upper thickening of the splinter body.
  • the invention is explained in more detail with reference to the drawing by an 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 casing shell 3.
  • the outer casing 3 is made of tough elastic plastic, e.g. Polyethylene, manufactured 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 consist, for example, of polystyrene.
  • a detonator head 5 is screwed onto the grenade body and carries the usual functional elements, such as bats, safety clips and detonator tubes 6.
  • the detonating tube 6 projects through the central opening of the splinter body 2 into the interior of the hand grenade, specifically into a recess in the explosive device 7.
  • 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 can 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 S1 of 135 ° and S2 of 160 °.
  • the possible upper thickening 11 of the wall of the splinter body is between the spherical sector S3 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 splinter 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, however, also advantageously be used in other “elongated” shapes of the splinter body, for example in the case of splinter bodies in the form of an ellipsoid, a cylinder, optionally with conical or hemispherical surfaces formed on top and bottom, and the like.
