Description

Die Erfindung bezieht sich auf ein Splittergeschoß nach dem Oberbegriff des Anspruchs 1.The invention relates to a fragmentary projectile according to the preamble of the claim 1.

Aus der EP-B1-0 101 795 ist ein Sprenggeschoß bekannt, bei dem außenseitig und zwar in einer Ausnehmung der Hülle mindestens eine Schicht vorgeformter Splitterkörper angeordnet sind. Zur Vergrößerung der Splitterwirkung im Kopfbereich des Sprenggeschosses sind am rückwärtigen Teil des Zünders eine Zwischenladung zur Beschleunigung von ebenfalls am Zünder angeordneten Splittern vorgesehen. Die am Zünder rückwärtig angeordneten Splitter werden durch die Zwischenladung radial beschleunigt, wobei ein vorderer, dickwandiger Abschnitt zur Befestigung des Zünders als Hemmung für die Ausbreitung der Splitter wirken kann.From EP-B1-0 101 795 an explosive projectile is known in which the outside and at least one layer of preformed splinter bodies in a recess in the casing are arranged. To increase the splinter effect in the head area of the explosive device are an intermediate charge on the rear part of the detonator intended to accelerate splinters also arranged on the igniter. The fragments arranged at the back of the igniter are replaced by the intermediate charge radially accelerated, with a front, thick-walled section for attachment of the detonator can act as an inhibitor to the spreading of the fragments.

Der Erfindung liegt die Aufgabe zugrunde, für ein Splittergeschoß eine Hülle vorzuschlagen, die eine große Splitterwirkung aufweist, bei Anordnung der Splitter im vorderen Bereich der Hülle eine möglichst große Wirkung nach vorne in Flugrichtung besitzt und bei verzögerter Zündung den Durchschlag eines Betonbauteils ermöglicht. Hierbei soll die Splitterwirkung nach dem Durchschlag des Betonbauteils gewährleistet sein.The invention has for its object to propose a shell for a fragmentary projectile, which has a large splintering effect when the splinters are arranged in the front area of the envelope has the greatest possible forward effect in the direction of flight owns and with delayed ignition the breakdown of a concrete component allows. Here, the splintering effect after the breakthrough of the concrete component to be guaranteed.

Die Erfindung löst diese Aufgabe entsprechend den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen. The invention solves this problem in accordance with the characterizing features of claim 1. Advantageous further developments of the invention are the dependent claims refer to.

Die Erfindung ermöglicht hohe Splittergeschwindigkeiten, in dem die Wandung, insbesondere im vorderen Geschoßhüllenbereich so weit minimiert wird, daß durch Versteifungsrippen/-stege oder durch eine andere Abstützung immer noch eine ausreichende Strukturfestigkeit vorliegt, um die Penetrationsfähigkeit des Splittergeschosses bei Durchschlag von Betonteilen, wie Betondecken zu gewährleisten.The invention enables high splinter speeds in which the wall, is minimized so far, in particular in the front projectile envelope area, that by Stiffening ribs / webs or by another support still one there is sufficient structural strength to the penetration ability of the fragmentary floor to ensure penetration of concrete parts such as concrete ceilings.

Wesentlich für die Erfindung ist die Bildung eines Fensters in der Splitterhülle, aus dem die Konstruktionssplitter mit großer Geschwindigkeit ausstoßbar sind. Das Fenster kann ringförmig oder durch Sprossen bzw. Rippen unterteilt oder auch in axialer Richtung mehrfach hintereinander in der Splitterhülle vorgesehen sein. Das Fenster selbst ist durch eine erhebliche Materialschwächung der Splitterhülle gebildet, wobei die Außenkontur der Splitterhülle durch die Bildung des Fensters nicht beeinträchtigt ist, d. h., es sind an der Außenkontur keinerlei Merkmale erkennbar, die auf die Bildung eines Fensters deuten lassen. Spalten oder Stufen an der Außenkontur entfallen daher, so daß keinerlei Kerbwirkung der Splitterhülle provoziert wird.
Erfindungsgemäß ist es erstmals möglich, durch konstruktiv einfache Maßnahmen eine winkelmäßig bevorzugte Splitterstreuung zu erreichen, wobei durch die Anordnung des Fensters im vorderen Bereich der Geschoßhülle in Verbindung mit der heckseitigen bzw. bodenseitigen Initiierung der Sprengladung eine hohe Richtwirkung und Geschwindigkeit der Splitter nach vorn erreicht wird. Durch die bodenseitige Initiierung der Sprengladung verläuft die Detonationswelle bzw. die Detonationsfront von der Bodenseite nach vorn durch das Geschoß und ergibt einen besonders kleinen Abstrahlwinkel der Splitter in Bezug auf die Längsachse des Splittergeschosses.It is essential for the invention to form a window in the splinter cover from which the construction splinters can be ejected at high speed. The window can be ring-shaped or divided by rungs or ribs or can be provided several times in succession in the splinter casing in the axial direction. The window itself is formed by a considerable weakening of the material of the splinter casing, the outer contour of the splinter casing not being impaired by the formation of the window, ie there are no features recognizable on the outer contour that indicate the formation of a window. Gaps or steps on the outer contour are therefore omitted, so that no notch effect of the splinter casing is provoked.
According to the invention, it is possible for the first time to achieve structurally simple measures to achieve an angularly preferred splinter scatter, the arrangement of the window in the front area of the projectile shell in conjunction with the initiation of the explosive charge on the rear or the bottom providing a high level of directionality and speed of the splinters to the front , Due to the initiation of the explosive charge on the bottom side, the detonation wave or the detonation front runs from the bottom side forward through the projectile and results in a particularly small radiation angle of the fragments with respect to the longitudinal axis of the fragmentary storey.

Entsprechend den Fig. 1 bis 3 weist ein Geschoßhülle 1 eines nicht weiter dargestellten Splittergeschosses in ihrem vorderen Bereich verschieden strukturierte Abschnitte auf, nämlich einen dickwandigen Abschnitt 2 zur Aufnahme eines nicht dargestellten Zünders bzw. einer ebenfalls nicht dargestellten Geschoßhaube in einem Gewinde 3, einen dünnwandigen Abschnitt 4, einen Abschnitt 5 mit zunehmender Dicke und einen Abschnitt 6 mit üblicher Dicke einer bekannten Geschoßhülle nach der DE 38 04 351 A1.According to FIGS. 1 to 3, a shell 1 has one not shown Splinter floor in its front area differently structured sections on, namely a thick-walled section 2 for receiving a not shown detonator or a floor hood also not shown in a thread 3, a thin-walled section 4, a section 5 with increasing Thickness and a section 6 with the usual thickness of a known projectile casing according to DE 38 04 351 A1.

Der Abschnitt 4 ist durch eine innere Ausnehmung 7 gebildet, wobei die Außenkontur 8 unverändert bleibt. Die Dicke 9 der Geschoßhülle im Abschnitt 4 beträgt wenige Millimeter. Ausgehend von dieser Dicke 9 steigt dann diese Dicke in Pfeilrichtung 10 kontinuierlich an bis zu Beginn des Abschnittes 6.The section 4 is formed by an inner recess 7, the outer contour 8 remains unchanged. The thickness 9 of the shell in section 4 is a few millimeters. Starting from this thickness 9, this thickness then increases in the direction of the arrow 10 continuously until the beginning of section 6.

Ein Stützkörper 12 ist in einer Ausnehmung 11 entgegen der Pfeilrichtung 10 eingeschraubt. Der Stützkörper 12 besteht aus einem hohlen Zapfen 13 mit Gewinde 14, einem Zentralrohr 15 und vier Versteifungsrippen 16 mit dazwischen liegenden, segmentförmigen Freiräumen 17 zur Aufnahme von Splitterpaketen 21, bestehend aus Konstruktionssplittern 18.A support body 12 is screwed into a recess 11 against the direction of the arrow 10. The support body 12 consists of a hollow pin 13 with a thread 14, a central tube 15 and four stiffening ribs 16 with intermediate, segment-shaped free spaces 17 for receiving fragments 21 from construction splinters 18.

Gemäß Fig. 1 stützen die Versteifungsrippen 16 die dünne Wand 19 im Abschnitt 4. Die Dicke 9 der Wand 19 beträgt einen Bruchteil der Dicke 20 der Geschoßhülle 1 im Abschnitt 6. Maßgebend für die Dicke 9 ist die zu gewährleistende Penetration eines Betonzieles. Sie kann in Abhängigkeit vom Geschoßkaliber 30 bis 70% der Dicke 20 betragen. Ein Stützwirkung geht auch von den zwischen den Versteifungsrippen 16 angeordneten Splitterpaketen 21 aus.1, the stiffening ribs 16 support the thin wall 19 in the section 4. The thickness 9 of the wall 19 is a fraction of the thickness 20 of the shell 1 in section 6. The decisive factor for the thickness 9 is the penetration to be guaranteed of a concrete target. Depending on the projectile caliber, it can be 30 to 70% the thickness be 20. A support effect also comes from between the stiffening ribs 16 arranged splinter packs 21.

Die Splitterpakete 21 erstrecken sich in Längsrichtung zwischen den Ebenen 30, 31 gemäß einem Abschnitt 29 Die Splitterpakete 21 können sich auch bis zur strichpunktiert gezeichneten, rund gezeichneten Kontur 32 erstrecken. The splinter packs 21 extend in the longitudinal direction between the levels 30, 31 according to a section 29 The splinter packs 21 can also be dash-dotted drawn, drawn round contour 32.

Die Konstruktionssplitter 18 sind als Kugeln, Kuben, Ellipsoide ausgebildet und in einem Füllmaterial 24 eingebettet, das die Stoßwellenimpedanz bzw. weitgehend die Stoßwellenimpedanz der Konstruktionssplitter 18 aufweist. Dies führt, in Verbindung mit den vorbeschriebenen Maßnahmen zu einer großen kinetischen Energie der Konstruktionssplitter 18 bei Detonation des Splittergeschosses.The construction splinters 18 are designed as spheres, cubes, ellipsoids and embedded in a filler material 24, which is the shock wave impedance or largely the shock wave impedance of the construction splitter 18. This leads to, in conjunction with the measures described above to a large kinetic Energy of the constructional fragments 18 upon detonation of the fragmentary floor.

Das Zentralrohr 15 dient zur Aufnahme einer nicht gezeichneten Zündstrecke oder Zündleitung für einen bodenseitigen Zünder oder auch für eine nur angedeutete Sprengladung 33 einer Hauptsprengladung 34. Das Zündrohr 15 kann auch entfallen zugunsten des Volumens der Splitterpakete 21.The central tube 15 serves to accommodate an ignition path or not shown Ignition cable for a base-side igniter or also for an implied one Explosive charge 33 of a main explosive charge 34. The ignition tube 15 can also be omitted in favor of the volume of the fragments 21.

Bei Einsatz von Bodenabstandszündern bzw. Annäherungszündern, wobei der Zündpunkt an oder im Bereich des Bodens des Splittergeschosses liegt, wird eine große Wirkung nach vorne in Flugrichtung bzw. zum Boden hin erreicht. Die Konstruktionssplitter 18 erreichen eine große Reichweite, da zum Aufbrechen der Wand 19 im Abschnitt 29 eine verhältnismäßig geringe Verformungsarbeit erforderlich ist.When using ground-based detonators or proximity detonators, the Ignition point is at or in the area of the floor of the fragmentary floor, one great effect in the direction of flight or towards the ground. The Construction splinters 18 reach a long range, because to break up the Wall 19 in section 29 requires a relatively small amount of deformation work is.

Andererseits ist die Penetrationsfähigkeit des Splittergeschosses von Betondecken gewahrleistet. Die dafür notwendige Strukturfestigkeit des Splittergeschosses ist durch die Versteifungsrippen 16 inklusive der Splitterpakete 21 gegeben.On the other hand, the penetrability of the fragmentary floor of concrete ceilings ensured. The structural strength of the splinter floor required for this is given by the stiffening ribs 16 including the splinter packs 21.

Bei einem Stützkörper 42 entsprechend Fig. 4 ist der Zapfen 13 über ein Gewinde 43 mit einem Zentralrohr 44 mit Flansch 45 verbunden. Ein ringförmiges Splitterpaket 46 liegt um das Zündrohr 44 und zwischen Wänden 47, 48.
Ein ebenfalls an der Wand 47 anliegendes Splitterhemd 49 aus Stahl bedeckt das Splitterpaket 46 umfangsseitig und liegt in einem Absatz 50 des Flansches 45. Aufgrund des homogenen Splitterpaketes 46 mit durchgängigen Konstruktionssplittern 18 liegt eine höhere Anzahl von Konstruktionssplittern 18 vor als bei den Splitterpaketen 21 innerhalb des Stützkörpers 12 nach den Fig. 1 - 3.
Die Stützwirkung der Wand 19 der Geschoßhülle 1 liegt durch das Splitterpaket 46 mit dem Splitterhemd 49 und dem Flansch 45 vor. In a support body 42 according to FIG. 4, the pin 13 is connected via a thread 43 to a central tube 44 with a flange 45. An annular splinter packet 46 lies around the ignition tube 44 and between walls 47, 48.
A splinter shirt 49 made of steel, which also lies against the wall 47, covers the splinter packet 46 on the circumferential side and lies in a shoulder 50 of the flange 45. Because of the homogeneous splinter packet 46 with continuous construction splinters 18, there is a higher number of construction splinters 18 than with the splinter packs 21 within the Support body 12 according to FIGS. 1-3.
The support effect of the wall 19 of the projectile casing 1 is provided by the fragment package 46 with the fragment shirt 49 and the flange 45.

Nach den Fig. 5, 6 weist ein Splittergeschoß 51 einen Annäherungszünder 53 und in der Geschoßhülle 1 einstückige Versteifungsrippen 52 auf. Diese erstrecken sich über die Abschnitte 4 und 5.5, 6, a fragmentary projectile 51 has a proximity fuse 53 and in the projectile casing 1 one-piece stiffening ribs 52. These extend through sections 4 and 5.

Die Hauptsprengladung 34 ist entsprechend den angeschrägten Versteifungsrippen 52 und einem Zündrohr 54 durch einen Hals 35 flaschenhalsförmig. Splitterpakete 56 liegen zwischen den Versteifungsrippen 52 und zwischen den Ebenen 30 und einer Ebene 55. Radial gesehen sind die Splitterpakete 56 begrenzt durch eine dünnwandige Hülse 57 zwischen der Hauptsprengladung 34, 35 und den Splitterpaketen 56 sowie durch die Wand 19 und eine Konuswand 22. Ein Zündübertrager ist mit 58 bezeichnet und füllt in einem kurzen Abschnitt 59 die Hülse 57 aus. Damit ist die Hülse 57 nur zu einem Teil von ca. 67% mit Sprengstoff 36 gefüllt.The main explosive charge 34 corresponds to the beveled stiffening ribs 52 and an ignition tube 54 through a neck 35 in the shape of a bottle neck. splitter packages 56 lie between the stiffening ribs 52 and between the levels 30 and a plane 55. Seen radially, the fragment packets 56 are delimited by a thin-walled sleeve 57 between the main explosive charge 34, 35 and the fragments 56 and through the wall 19 and a cone wall 22. An ignition transformer is designated 58 and fills the sleeve 57 in a short section 59. The sleeve 57 is thus only partially filled with explosives 36 by approximately 67%.

Ein wesentlich größerer Sprengstofffüllungsgrand von 100% liegt bei dem Splittergeschoß 60 mit nicht gezeichnetem Bodenzünder nach den Fig. 7, 8 vor. Die Geschoßhülle 1 ist mit einer Geschoßhaube 61 verschraubt. Die Hauptsprengladung 34 erstreckt sich - flaschenförmig verjüngt - bis in die Ebene 30. Dadurch liegt bei Detonation der Hauptsprengladung 34 eine Beschleunigung der Konstruktionssplitter 18 auch im vorderen Abschnitt 59, siehe Fig. 5 vor. Ansonst entspricht die Splittereinrichtung der zu den Fig. 5, 6 beschriebenen Splittereinrichtung. Anstelle des Bodenzünders kann auch ein Kopfzünder eingesetzt sein.A much larger explosive charge level of 100% lies with the fragmentary floor 60 with undrawn ground igniter according to FIGS. 7, 8 before. The Projectile casing 1 is screwed to a projectile hood 61. The main explosive charge 34 extends - tapered in a bottle shape - up to level 30 If the main explosive charge 34 detonates, there is an acceleration of the construction splinters 18 also in the front section 59, see FIG. 5 before. Otherwise corresponds the splitter device of the splitter device described for FIGS. 5, 6. A top detonator can also be used instead of the ground igniter.

Nach den Fig. 9, 10 ist ein Splitterpaket 76 pfropfenförmig, also ohne zentrale Ausnehmung bzw. Bohrung ausgebildet und mit einer Scheibe 77 aus Stahl heckseitig vollständig gegenüber der Sprengladung 34 abgedeckt. Zur Geschoßspitze hin liegt das Splitterpaket 76 an einem, nach der Penetration eines Betonzieles leicht zerlegbaren bzw. absprengbaren Einschraubkörper 78 sowie an einer Wand 79 der Geschoßhülle 1 an. Die mit der Geschoßhülle 1 einstückigen Rippen 52.1 sind in den Konstruktionssplittern 18 eingebettet. Die Splitterwirkung nach vorne in einem Winkel 80 von ca. 120° ist - ohne einen toten Splitterbereich - aufgrund eines verwendeten Bodenzünders gegeben. Der Einschraubkörper 78 besteht aus Hartmetall oder einem geeigneten Stahl.9, 10, a fragment packet 76 is plug-shaped, that is to say without a central one Recess or bore formed and with a washer 77 made of steel on the rear side completely covered against the explosive charge 34. To the top of the floor the fragment packet 76 lies against one after penetration of a concrete target easily dismantled or detachable screw-in body 78 and on a wall 79 of the shell 1. The one-piece with the projectile casing 1 ribs 52.1 are embedded in the construction splinters 18. The splinter effect to the front at an angle 80 of approx. 120 ° is due to - without a dead splinter area given a ground igniter used. The screw-in body 78 consists of Carbide or a suitable steel.

Anstelle der gezeichneten kugelförmigen Konstruktionssplitter 18 ist auch eine andere Formgebung der Konstruktionssplitter 18 wie Kuben, Plattenform, möglich.Instead of the drawn spherical construction splinters 18 there is also one other shapes of the construction splinters 18 such as cubes, plate shape, possible.
