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
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
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.
