Description

Die Erfindung bezieht sich auf einen Splitterkörper für Granaten, insbesondere Handgranaten, bestehend aus einem Hohlkörper, dessen Wandung aus in Kunststoff eingebetteten Metallpartikeln besteht und der eine von der Kugelform abweichende gestreckte Gestalt aufweist, in deren Achse der Splitterkörper mindestens eine Öffnung besitzt, wobei die Wand des Splitterkörpers eine achssymmetrische Verdickung mit einer gegenüber den benachbarten Wandbereichen des Splitterkörpers erhöhten Anhäufung von Metallpartikeln aufweist.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.

Um bei einer Granate, insbesondere Handgranate, eine möglichst gleichmäßige Splitterverteilung zu erreichen, wäre an sich die Kugelform des Splitterkörpers mit einem im Zentrum der Kugel angeordneten Detonator ideal. In diesem Falle erreicht nämlich die vom Detonator ausgehende Detonationswelle alle Punkte der inneren Kugelfläche des Splitterkörpers im gleichen Augenblick, sodaß auch die Zerlegung des gesamten Splittermantels gleichzeitig erfolgt. Kugelförmige Splitterkörper lassen sich jedoch in der Praxis nicht immer realisieren, und zwar einerseits aus ballistischen Gründen, andererseits - insbesondere bei Handgranaten - aus Gründen der Dimensionierung. Wenn nämlich die erforderliche Splitteranzahl und die benötigte Sprengstoffmenge eine relativ große Kugel als Splitterkörper ergäbe, wäre die Handlichkeit einer solchen Handgranate beeinträchtigt. Es werden daher Handgranaten für größere Splitter- und Detonationsleistungen üblicherweise nicht mit kugelförmigen, sondern mit eiförmigen oder sonstwie gestreckten Splitterkörpern ausgebildet. Bei diesen Handgranaten ist jedoch die Splitterverteilung unregelmäßig, d.h. in verschiedenen Richtungen bezogen auf das dreidimensionale Achssystem der Handgranate unterschiedlich.In order to achieve the most uniform possible splinter distribution in a grenade, in particular a hand grenade, the spherical shape of the splinter body with a detonator arranged in the center of the ball would be ideal. In this case, 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. If the required number of fragments and the amount of explosives required resulted in a relatively large ball as a splinter body, the handiness of such a hand grenade would be impaired. 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. In the case of these hand grenades, however, the splinter distribution is irregular, ie different in different directions with respect to the three-dimensional axis system of the hand grenade.

Es sind Splitterkörper für Handgranaten bekannt geworden, die etwa im mittleren Bereich oder etwas über der Mitte der Seitenwand eine nach innen gerichtete Verdickung aufweisen, wodurch der Innenraum der Handgranate in zwei Teilräume, einen meist kleineren oberen und einen größeren unteren, unterteilt wird (AT-A-357 904, AT-A 368 280). Mit dieser Maßnahme sollte die Ausbreitung der Detonationswelle im Inneren der Handgranate im Sinne einer gleichmäßigen Austreuung der Splitter bzw. Metallpartikel beeinflußt werden. Dieser Effekt hat jedoch in der Praxis keine ausreichende Wirkung gezeigt.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. However, this effect has not shown sufficient effect in practice.

Es blieb daher nach wie vor die Aufgabe ungelöst, einen Splitterkörper für eine Granate, insbesondere Handgranate zu schaffen, der - obgleich nicht von kugelförmiger Gestalt - ähnlich wie ein kugelförmiger Splitterkörper eine möglichst gleichmäßige Splitterverteilung garantiert.It was therefore still unsolved the task of creating a splinter body for a grenade, in particular a hand grenade, which - although not of a spherical shape - similarly to a spherical splinter body, guarantees the most uniform possible splinter distribution.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß die Verdickung der Wand der Splitterkörpers im Übergangsbereich zwischen der Bodenfläche und der Seitenfläche ausgebildet ist, daß sich der Detonator bzw. das Detonatorzentrum wenigstens annähernd im Bereich des Mittelpunktes des Splitterkörpers befindet, und daß die Verdickung der Wand des Splitterkörpers, bezogen auf eine zum Mittelpunkt des Splitterkörpers konzentrische Kugelfläche, im Bereich zwischen den Kugelsektoren von 130° und 165°, vorzugsweise von 135° und 160° liegt, wobei die Nullgradachse mit der Achse des Splitterkörpers zusammenfällt und zur Öffnung des Splitterkörpers weist. Die Bodenfläche ist die der Öffnung für den Zünder gegenüberliegende Innenfläche des Splitterkörpers.The solution to this problem is according to the invention that 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.

Es hat sich herausgestellt, daß mit Hilfe der erfindungsgemäßen Maßnahme im Vergleich zu einer Handgranate mit einem Splitterkörper von eiförmiger Gestalt in bekannter Ausführung eine gleichmäßigere Verteilung von wirksamen Splittern, d.h. eine gleichmäßigere Verteilung der Splitterdurchschläge durch eine Prüfwand erzielt wird, die die zu prüfende Handgranate in einem bestimmten Abstand zylinderförmig umgibt.It has been found that with the aid of the measure according to the invention, in comparison with a hand grenade with a splinter body of egg-shaped shape in a known design, a more uniform distribution of effective splinters, i.e. a more even distribution of the chip penetration is achieved by a test wall, which surrounds the hand grenade to be tested at a certain distance in a cylindrical shape.

Die erfindungsgemäße Verdickung der Wand des Splitterkörpers wird vorteilhafterweise in das Innere der Handgranate gerichtet, und zwar in Form einer nach innen gerichteten Auswölbung der Innenwand, da eine nach außen gerichtete Verdickung die Außenform der Handgranate eher ungünstig beeinflussen würde.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.

Wichtig ist vor allem eine erhöhte Anhäufung von Metallpartikeln in der Wand des Splitterkörpers im Übergangsbereich zwischen der Bodenfläche und der Seitenfläche des Splitterkörpers, weil gerade in dem diesem Bereich entsprechenden Splitterstreusektor ein auffälliges Defizit an Splitterdurchschlägen wahrgenommen wurde. Ein ähnliches Splitterdurchschlagsdefizit kann aber auch in der dem Wandbereich des Splitterkörpers zwischen Schulterfläche und Seitenfläche zugeordneten Splitterstreusektor auftreten. Es ist daher gegebenenfalls vorteilhaft, wenn auch im Übergangsbereich zwischen der Schulterfläche und der Seitenfläche eine Verdickung ausgebildet ist, welche Verdickung im Bereich zwischen den Kugelsektoren 15° und 50°, vorzugsweise von 20° und 45° liegt. Als Schulterfläche wird die die Öffnung für den Zünder umgebende Innenfläche des Splitterkörpers bezeichnet.Above all, 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.

Im Hinblick auf die gestreckte Gestalt der Granate ist für eine optimale Splitterverteilung auch zweckmäßig, wenn sich der Detonator längs der Achse des Splitterkörpers erstreckt und mit Abstand oberhalb der unteren Verdickung bzw. mit Abstand unterhalb der oberen Verdickung des Splitterkörpers endet.In view of the elongated shape of the grenade, it is also expedient for an optimal splinter distribution if 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.

Die Erfindung wird anhand der Zeichnung durch ein Ausführungsbeispiel näher erläutert. Die Zeichnung zeigt eine Handgranate, teilweise im Vertikalschnitt.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.

Die in der Zeichnung dargestellte Handgranate weist einen Handgranatenkörper 1 auf, der aus einem inneren, als Hohlkörper ausgebildeten Splitterkörper 2 und einem äußeren Gehäusemantel 3 besteht. Der äußere Gehäusemantel 3 ist aus zähelastischem Kunststoff, z.B. Polyäthylen, gefertigt und weist einen halsförmigen Ansatz 4 mit Außengewinde auf. Die Wand des Splitterkörpers 2 besteht aus in Kunststoff eingebetteten Metallpartikeln in Form von Stahlkugeln. Die Metallpartikel sind in dichter Packung angeordnet. Der die Metallpartikel verbindende Kunststoff kann beispielsweise aus Polystyrol bestehen.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.

Auf dem Handgranatenkörper ist ein Zünderkopf 5 aufgeschraubt, der die üblichen Funktionselemente, wie Schläger, Sicherungsbügel und Zündröhrchen 6 trägt. Das Zündröhrchen 6 ragt durch die zentrale Öffnung des Splitterkörpers 2 in das Innere der Handgranate, und zwar in eine Aussparung des Sprengsatzes 7.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.

Die Wand des Splitterkörpers 2 weist im Übergangsbereich zwischen der Bodenfläche 8 und der Seitenfläche 9 eine achssymmetrische Verdickung 10 in Form einer nach innen gerichteten Auswölbung auf. In dieser Verdickung 10 befindet sich eine gegenüber den benachbarten Wandbereichen des Splitterkörpers 2 erhöhte Anhäufung von Metallpartikeln.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.

Gegebenenfalls kann auch im Übergangsbereich zwischen der Schulterfläche 12 und der Seitenfläche 9 des Splitterkörpers eine achssymmetrische Verdickung 11 (in der Zeichnung strichliert angedeutet) in Form einer nach innen gerichteten Auswölbung vorhanden sein.Optionally, an axially symmetrical thickening 11 (indicated by dashed lines in the drawing) 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.

In der Zeichnung ist auch eine zum Mittelpunkt M des Splitterkörpers konzentrische Kugelfläche K dargestellt.The drawing also shows a spherical surface K which is concentric with the center M of the splinter body.

Die mit der Achse A des Splitterkörpers zusammenfallende und vom Mittelpunkt M in Richtung zur Zünderöffnung weisende Achse der Kugelfläche K wird als deren Nullgradachse definiert. Die Verdickung 10 der Wand des Splitterkörpers liegt beim dargestellten Ausführungsbeispiel zwischen den Kugelsektoren S₁ von 135° und S₂ von 160°. Die allfällige obere Verdickung 11 der Wand des Splitterkörpers liegt zwischen dem Kugelsektor S₃ von 20° und S₄ von 45°. Der Mittelpunkt M des Splitterkörpers ist der Halbierungspunkt der axialen Erstreckung (Außenmaß) des Splitterkörpers 2.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.

Der Detonator 13, der im unteren Teil des Zündröhrchens 6 angeordnet ist und beispielsweise aus vier Teilladungen besteht, ist so angeordnet, daß sein Zentrum sich im mittelpunkt M des Splitterkörpers befindet. Der sich in Richtung der Achse A des Splitterkörpers erstreckende Detonator endet unten mit Abstand oberhalb der Verdickung 10 und oben mit Abstand unterhalb der Verdickung 11 (falls eine solche vorhanden ist).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).

Das dargestellte Ausführungsbeispiel zeigt einen im wesentlichen eiförmigen Splitterkörper. Die erfindungsgemäße Maßnahme läßt sich mit Vorteil aber auch bei anderen "gestreckten" Formen des Splitterkörpers einsetzen, beispielsweise bei Splitterkörpern in Form eines Ellipsoides, eines Zylinders,gegebenenfalls mit oben und unten angeformten Kegel- oder Halbkugelflächen,u.dgl.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.
