Abstract

A projectile (10), where necessary covered with a jacket, possesses a front-side core (1) and a rear-side core (2). The rear-side core (2) here bears positively in a centered manner against the front-side core (1) and this rear-side core (2) fills the entire cylindrical and the frustoconically configured rear region (2) of the projectile (10). A contact zone (11, 12 is respectively configured on the two cores (1, 2), which contact zone allows the projectile (10) to be joined together in a press fit, a perfectly aligned external form (3) of the projectile (10) being obtained and the contact faces (15; 13; 11 to 12) of the cores (1, 2) directly touching one another substantially without a clearance or gap over the whole of the contact face (15; 13; 11 to 12). When the projectile (10) impacts upon a surface oriented in any chosen manner relative to the firing direction (20), the projectile (10) is split into two less dangerous projectile parts.

Description

Die Erfindung betrifft ein Geschoss mit einem frontseitigen Kern und mit einem heckseitigen Kern, wobei die Aussenform des Geschosses, von der Geschossspitze ausgehend betrachtet, in ogiver Form ausgebildet ist, in einen zylindrischen Mittelbereich übergeht und in einem konischen Heckbereich endet, wobei der heckseitige Kern formschlüssig zentriert an dem frontseitigen Kern anliegt und wobei dieser heckseitige Kern den gesamten zylindrischen und den kegelstumpfförmig ausgebildeten Heckbereich des Geschosses ausfüllt.The invention relates to a projectile having a front core and a rear core, wherein the outer shape of the projectile, viewed from the projectile nose, is formed in ogiver form, merges into a cylindrical central region and ends in a conical rear region, wherein the rear core form-fitting centered on the front core is present and wherein this rear-side core fills the entire cylindrical and the truncated cone shaped rear portion of the projectile.

Ein solches Geschoss ist als Mantelgeschoss aus der WO 99/10703 bekannt, wobei zweiteilige Geschosse schon seit mehr als 60 Jahren, beispielsweise aus GB 601 686 , bekannt sind. Die zentrische formschlüssige Anpassung des heckseitigen Kerns an den frontseitigen Kern gestattet es einem nach der WO 99/10703 konzipierten Geschoss, gute aerodynamische, ballistische und vor allem Durchdringungs-Eigenschaften für Scharfschützeneinsätze zu bieten.Such a projectile is as a coat bullet from the WO 99/10703 known, with two-part projectiles for more than 60 years, for example GB 601 686 , are known. The centric positive fit of the rear core to the front core allows one after the WO 99/10703 designed missile to provide good aerodynamic, ballistic and, above all, penetration characteristics for sniper missions.

Aus der DE 100 05 412 ist ein Übungsgeschoss bekannt, welches eine reduzierte Reichweite aufweist. Es besteht aus einer Geschossspitze, die über Sollbruchstellen mit einem Heckkern verbunden ist. Beim Abschuss des Geschosses zerbricht durch die Massenträgheit der Geschossspitze das Geschoss, so dass nur eine reduzierte Flugweite erreicht wird.From the DE 100 05 412 is a practice floor known, which has a reduced range. It consists of a projectile nose, which is connected via predetermined breaking points with a tail core. When shooting the projectile breaks through the inertia of the projectile nose the bullet, so that only a reduced flying distance is achieved.

Die US 6,263,798 beschreibt ein Geschoss, welches bei erhöhter Temperatur aber unterhalb der Sintertemperatur erzeugt wird, so dass es sich beim Einschlag direkt und vollständig in Pulverform zerlegt. Diese Druckschrift gibt an, dass sich dieses Verfahren zudem für die Herstellung von bleifreier Übungsmunition eignet.The US 6,263,798 describes a projectile which is generated at elevated temperature but below the sintering temperature, so that it decomposes directly and completely in powder form during the impact. This document indicates that this method is also suitable for the production of lead-free practice ammunition.

Die genannten Übungsmunitionen nach dem Stand der Technik sind teuer in der Herstellung und ihr Schussverhalten entspricht auf grösseren Entfernungen nicht dem von Kampfmunition.The aforementioned practice munitions according to the prior art are expensive to produce and their shooting behavior does not correspond to that of combat ammunition at greater distances.

Aus der EP 0 563 552 ist ein Geschoss bekannt, welches für Weitflugzwecke geeignet ist. Das Geschoss ist dabei zweiteilig ausgebildet, wobei beispielsweise die Spitze aus Schwermetall und ein Führungsteil aus Tombak ist. Dieses Geschoss bildet eine Grundlage für den Oberbegriff des Anspruchs 1.From the EP 0 563 552 is a projectile known which is suitable for long-haul flights. The projectile is formed in two parts, wherein, for example, the tip of heavy metal and a guide member is Tombak. This bullet forms a basis for the preamble of claim 1.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Geschoss anzugeben, welches als Übungsmunition billiger und zudem bleifrei herstellbar ist.Based on this prior art, the present invention seeks to provide a bullet, which is cheaper than exercise ammunition and also lead-free manufacture.

Eine weitere Aufgabe besteht darin, bei einem nicht frontalen Aufprallen des als Übungsmunition konzipierten Geschosses das Ricochet-Verhalten zu verbessern, das heisst die Gefährdung von Dritten durch Abprallen und weiterflug des Geschosses sicherer auszuschliessen.A further object is to improve the ricochet behavior in the event of a non-frontal impact of the projectile designed as a training ammunition, that is to say to exclude the danger to third parties by rebounds and onward flight of the projectile more securely.

Schliesslich ist es Aufgabe der vorliegenden Erfindung, eine Übungsmunition anzugeben, die auf die gleichen Distanzen eingesetzt werden kann wie Kampfmunition, das heisst, die im wesentlichen bis zum Einschlag dieselben ballistischen Eigenschaften aufweist.Finally, it is an object of the present invention to provide a training ammunition that can be used at the same distances as combat ammunition, that is, which has the same ballistic properties substantially until the impact.

Diese Aufgabe wird für ein Geschoss der eingangs genannten Art durch die Merkmale des Anspruchs 1 gelöst.This object is achieved for a projectile of the type mentioned by the features of claim 1.

Dadurch, dass das Geschoss als einstückiges Element den Lauf der Feuerwaffe verlässt, ist eine der Kampfmunition ähnliches Flugverhalten für Geschwindigkeit und Flugbahn erreichbar. Durch das Zerlegen des Geschosses in zwei beispielsweise ungefähr gleich grosse Teile beim Aufprall unter einem mehr oder weniger beliebigen Abprallwinkel, wird eine Gefährdung Dritter ausgeschlossen, ohne dass man zu einem Zerplatzen der Übungsmunition in Puderform oder ähnliches zurückgreifen muss. Die Konzeption der Munition als reines Stahlgeschoss verbilligt die Herstellung. Es sind weiter Sonderfunktionen wie Leuchtspur etc. in einfacher Weise integrierbar.The fact that the projectile as an integral element leaves the barrel of the firearm, a combat ammunition similar flight behavior for speed and trajectory is achievable. By dismantling the projectile into two, for example, approximately equal parts upon impact under a more or less arbitrary rebound angle, a risk to third parties is excluded, without having to fall back to a bursting of the training ammunition in powder form or the like. The conception of ammunition as a pure steel bullet makes production less costly. There are further special functions such as tracer, etc. integrated in a simple manner.

Vorteilhafte Ausführungsformen sind in den Unteransprüchen gekennzeichnet.Advantageous embodiments are characterized in the subclaims.

Die Erfindung wird nun unter Bezugnahme auf die einzige Figur näher beschrieben, die eine Explosionsansicht eines Geschosses darstellt.The invention will now be described in more detail with reference to the single figure, which is an exploded view of a projectile.

Die einzige Figur zeigt ein zweiteiliges Geschoss 10, welches hier ohne Mantel ausgestaltet ist. Es verfügt über einen frontseitigen Kern 1 und einen heckseitigen Kern 2. Die Aussenform 3 des Geschosses 10, von der Geschossspitze 4 ausgehend betrachtet, ist in ogiver Form ausgebildet und geht in einen zylindrischen Mittelbereich 5 über und endet in einem konischen Heckbereich 6. Der Mittelbereich 5 verfügt über eine umlaufende gerundete Nut 7. Die beiden Kerne 1 und 2 bestehen aus Vollmaterial.The single figure shows a two-part projectile 10, which is designed here without a coat. It has a front core 1 and a rear core 2. The outer shape 3 of the projectile 10, viewed from the projectile nose 4, is formed in ogiver shape and merges into a cylindrical central region 5 and ends in a conical rear region 6. The middle region 5 has a circumferential rounded groove 7. The two cores 1 and 2 are made of solid material.

Dabei ist der heckseitige Kern 2 formschlüssig zentriert auf dem frontseitigen Kern 1 mit Hilfe eines Eingriffbereichs aufgesetzt, der die Bezugszeichen 11 und 12 trägt. Die Grössenverhältnisse von frontseitigem Kern 1 und heckseitigem Kern 2 sind dabei so, dass dieser heckseitige Kern 2 den gesamten zylindrischen Mittelbereich 5 und den kegelstumpfförmig ausgebildeten Heckbereich 6 des Geschosses 10 ausfüllt. Die Verbindung zwischen den beiden Kernen 1 und 2 kann ein Presssitz sein, was beispielsweise hier bedeutet, dass durch einfache Beaufschlagung von beiden Kernen 1 und 2 mit Scherkräften durch einen Benutzer die beiden Kerne 1 und 2 nicht getrennt werden können. Die Passungen können entsprechend genau nach ISA spezifiziert sein. Insofern sind auch andere Sitze möglich. Wesentlich ist die Wirkung des Zusammenfügen des Geschosses 10, was zu einer gegenüber der Schwerkraft nicht lösenden Verbindung führt. Es ist auch möglich, dass die Verbindung der Geschosshälften eine Klemmverbindung ist und/oder ein Reibschluss, sofern gewährleistet ist, dass nur die Teile sich nur bei einem Aufprall, selbst unter geringem Winkel voneinander lösen. Unterstützend wirkt beim Zusammenhalt der Geschosses, das beim Einsatz im wesentlichen Kräfte in Längsrichtung auf das Geschoss 10 einwirken.In this case, the rear-side core 2 is positively placed centered on the front core 1 by means of an engagement region which carries the reference numerals 11 and 12. The size ratios of the front-side core 1 and the rear-side core 2 are such that this rear-side core 2 fills the entire cylindrical central region 5 and the truncated cone-shaped rear region 6 of the projectile 10. The connection between the two cores 1 and 2 may be an interference fit, which means here, for example, that by simply loading both cores 1 and 2 with shearing forces by a user, the two cores 1 and 2 can not be separated. The fits can be specified exactly according to ISA. In this respect, other seats are possible. Essential is the effect of the assembly of the projectile 10, which leads to a non-gravity connection. It is also possible that the connection of the projectile halves is a clamping connection and / or a frictional connection, provided that it is ensured that only the parts only come apart in the event of an impact, even at a low angle. Supportive acts in the cohesion of the projectile, which act on the projectile 10 in the use of substantially forces in the longitudinal direction.

Wenn dagegen das Geschoss 10, aus einer Feuerwaffe abgeschossen, nicht frontal auf eine Fläche auftrifft, beispielsweise auf eine Fläche, die beispielsweise in einem Winkel zwischen 5 und 30 Grad zur Flugrichtung, das heisst Längsachse 20, des Geschosses 10 steht, dann beaufschlagen ausreichende Scherkräfte das Geschoss 10 und es zerlegt sich in die zwei Kerne 1 und 2, womit der weitere Gefährdungsbereich nach dem Abpraller stark verkleinert wird. Bei einem Aufprall des Geschosses 10 auf eine beliebig zur Schussrichtung 20 orientierten Fläche wird das Geschoss 10 also in zwei ungefährlichere Geschossteile zerlegt.If, on the other hand, the projectile 10 fired from a firearm does not strike a surface face-to-face, for example a surface which is at an angle between 5 and 30 degrees to the direction of flight, ie longitudinal axis 20, of the projectile 10, sufficient shear forces are applied the projectile 10 and it breaks down into the two cores 1 and 2, whereby the other danger area is greatly reduced after the rebound. In a collision of the projectile 10 on an arbitrary oriented to the firing direction 20 surface, the projectile 10 is thus decomposed into two safer bullets.

Geeignete Ausführungen des Eingriffsbereiches der beiden Kerne 1 und 2 umfassen einen zentralen Stumpfkonus 11 des frontseitigen Kerns 1 mit einem Winkel zwischen 1 und 20 Grad, vorzugsweise zwischen 2 und 10 Grad, insbesondere von 3 Grad gegenüber der Längsachse 20 des Geschosses 10, und einem für den Presssitz oder einer Klemmverbindung geeigneten komplementären Konus 12 des heckseitigen Kerns 2. Dieser weist vorteilhafterweise fast den gleichen Winkel, insbesondere einen etwas kleineren Winkel, auf wie der Stumpfkonus 11, beispielsweise einen um 0,2 bis 1 Grad, insbesondere 0,5 Grad kleineren Winkel, das heisst hier einen Winkel von 2,5 Grad gegenüber der Längsachse 20 mit einem um 0,03 Millimeter kleineren Innendurchmesser des heckseitigen stumpfkegeligen Kernkonus 12, wenn die beiden Anschlagflächen 13 der beiden Kerne 1 und 2 aufeinandergedrückt werden, so dass kein Luftspalt an den Flächen 13 besteht.Suitable embodiments of the engagement region of the two cores 1 and 2 comprise a central butt cone 11 of the front core 1 at an angle between 1 and 20 degrees, preferably between 2 and 10 degrees, in particular 3 degrees relative to the longitudinal axis 20 of the projectile 10, and a for This advantageously has almost the same angle, in particular a slightly smaller angle, as the truncated cone 11, for example a smaller by 0.2 to 1 degree, in particular 0.5 degrees smaller Angle, that means here an angle of 2.5 degrees with respect to the longitudinal axis 20 by 0.03 millimeters smaller inner diameter of the rear frustoconical core cone 12 when the two abutment surfaces 13 of the two cores 1 and 2 are pressed together, so that no air gap at the surfaces 13 is.

Die Dicke der Wandung 14 des heckseitigen Kernkonus 12 beträgt in dem hier dargestellten Ausführungsbeispiel an der Anschlagfläche 13, das heisst im zylindrischen Mittelbereich 5, 1,17 Millimeter bei einem Aussendurchmesser von 10,884 Millimeter. Insbesondere kann die Wandstärke des stumpfkegeligen Hohlkonus 12 zwischen 1/5 und 1/3 des Durchmessers des Geschosses 10 in seinem zylindrischen Abschnitt betragen.The thickness of the wall 14 of the rear core cone 12 is in the embodiment shown here on the stop surface 13, that is, in the cylindrical central region 5, 1.17 millimeters at an outer diameter of 10.884 millimeters. In particular, the wall thickness of the frustoconical hollow cone 12 can be between 1/5 and 1/3 of the diameter of the projectile 10 in its cylindrical section.

Die Ausmasse der Anschlagflächen 15 sind dagegen an beiden Kernen 1 und 2 identisch. Die Anschlagflächen 15 verlaufen wie die Flächen 13 in einer Ebene senkrecht zur Längsrichtung 20 des Geschosses 10. Die Tiefe beziehungsweise Höhe der Koni 11 und 12 ist vorzugsweise identisch, so dass sich bei aufeinander gesetzten und angedrückten oder angepressten Kernen 1 und 2 ein auf der Aussenseite bündiges Geschoss 10 ergibt. Die Höhe des frontseitigen Kernkonus 11 beträgt bei diesem Ausführungsbeispiel 4 Millimeter und somit zwischen 1/4 bis 1/8, hier 1/6 der Länge eines der beiden Kerne 1 oder 2.The dimensions of the stop surfaces 15, however, are identical on both cores 1 and 2. The stop surfaces 15 extend like the surfaces 13 in a plane perpendicular to the longitudinal direction 20 of the projectile 10. The depth or height of the cones 11 and 12 is preferably identical, so that in successive set and pressed or pressed cores 1 and 2 on the outside flush bullet 10 results. The height of the front core cone 11 in this embodiment is 4 millimeters and thus between 1/4 to 1/8, here 1/6 of the length of one of the two cores 1 or 2.

Anstelle der Koni 11 und 12 der Kerne 1 und 2 können auch im wesentlichen komplementäre zylindrische Elemente ineinander greifen.Instead of the cones 11 and 12 of the cores 1 and 2 also substantially complementary cylindrical elements can interlock.

Die Kerne 1 und 2 hier sind vorteilhafterweise aus identischem Material ausgebildet. Insbesondere können die beiden Kerne 1 und 2 beide aus Stahl ähnlicher Härte oder gleichem Stahl bestehen, so dass sich eine Material-gleiche Verbindung, Klemmverbindung oder Presssitz ergibt. Die Herstellung ist gegenüber den Geschossen nach dem Stand der Technik sehr einfach. Insbesondere muss nicht der harte frontseitige Kern 1 und dann der weiche heckseitige Kern 2 in einen Mantel des Geschosses 10 gepresst werden.The cores 1 and 2 here are advantageously formed of identical material. In particular, the two cores 1 and 2 can both be made of steel of similar hardness or the same steel, resulting in a material-like connection, clamping connection or press fit. The production is opposite the storeys very simple according to the state of the art. In particular, it is not necessary to press the hard front core 1 and then the soft rear core 2 into a shell of the projectile 10.

Die Länge des frontseitigen Kerns 1 beträgt beispielsweise 24 Millimeter, während die Länge des heckseitigen Kerns 2 beispielsweise 23 Millimeter beträgt. Somit ist auf Grund der äusseren Form der Kerne 1 und 2 eine gleiche Gewichtsverteilung gegeben. Somit entstehen bei einem Aufprall des Geschosses 10 zwei im wesentlichen gleichgrosse und gleich schwere Bruchstücke. Das Längen- oder das Gewichtsverhältnis der Kerne 1 und 2 zueinander kann beispielsweise zwischen 1:3 bis 3:1, vorteilhafterweise zwischen 1:2 bis 2:1 und noch bevorzugter zwischen 1:1,3 bis 1,3:1 gewählt werden.The length of the front core 1 is for example 24 millimeters, while the length of the rear core 2 is for example 23 millimeters. Thus, due to the external shape of the cores 1 and 2, an equal weight distribution is given. Thus, in an impact of the projectile 10, two substantially equal and equally heavy fragments. The length or weight ratio of the cores 1 and 2 to one another can be selected, for example, between 1: 3 to 3: 1, advantageously between 1: 2 to 2: 1 and even more preferably between 1: 1.3 to 1.3: 1.

Das Geschoss 10 kann bei einem anderen Ausführungsbeispiel der Erfindung auch als Mantelgeschoss ausgestaltet sein, wobei der Mantel des Geschosses 10 dann nur Führungseigenschaften im Rohr aufweist und so dünn ausgestaltet ist, dass der Mantel in keiner Weise mit der Zerstörung des Geschosses 10 beim Auftreffen des Geschosses 10 auf ein Ziel interferiert. Bei der Herstellung eines solchen Mantelgeschosses werden dann vorteilhafterweise zuerst die in der Figur dargestellte zweiteiligen Kerne 1 und 2 zusammengedrückt, bevor ein Mantel über das so entstandene Geschoss 10 übergepresst wird. Dieser Mantel kann insbesondere in die Nut 7 eingebördelt werden.The projectile 10 may be configured as a shell projectile in another embodiment of the invention, the shell of the projectile 10 then only has leadership properties in the tube and is made so thin that the mantle in any way with the destruction of the projectile 10 upon impact of the projectile 10 interferes with a target. In the production of such a mantle projectile then advantageously the two-piece cores 1 and 2 shown in the figure are first compressed before a jacket is over-pressed over the resulting projectile 10. This jacket can be crimped in particular in the groove 7.

Statt einem Stumpfkegel 11 an dem frontseitigen Kern 1 und einem Hohlstumpfkegel 12 an dem heckseitigen Kern 2 kann das zweiteilige Geschoss 10 auch genau anders herum aufgebaut sein, wobei somit die wandungen 14 an dem frontseitigen Kern 1 ausgebildet sind.Instead of a truncated cone 11 on the front core 1 and a hollow truncated cone 12 on the rear core 2, the two-part projectile 10 can also be constructed exactly the other way round, whereby the walls 14 are thus formed on the front core 1.
