Description

Geschoss für Infanteriemunition Bullet for infantry ammunition
Die Erfindung betrifft ein Geschoss für Infanteriemunition nach dem Oberbegriff des Anspruchs 1.The invention relates to a projectile for infantry ammunition according to the preamble of claim 1.
Geschosse für Infanteriemunition bestehen bekanntermaßen aus einem Ge- schosskern mit einer Geschossspitze und einem Metallmantel, wobei der Geschosskem aus Blei besteht. Das Verschießen von Bleigeschossen erzeugt blei- staubhaltige Gase, die gesundheitsschädlich sind. Außerdem gefährdet Blei die Umwelt.Bullets for infantry ammunition are known to consist of a bullet core with a bullet tip and a metal jacket, the bullet core being made of lead. The firing of lead bullets produces gases containing lead dust that are harmful to health. Lead also endangers the environment.
Der Erfindung liegt die Aufgabe zu Grunde, ein Geschoss für Infanteriemunition nach dem Oberbegriff des Anspruchs 1 so zu verbessern, dass eine haltbare Verbindung zwischen Geschosskem und Metallmantel erreicht ist.The invention is based on the object of improving a projectile for infantry ammunition according to the preamble of claim 1 in such a way that a durable connection between the projectile core and the metal jacket is achieved.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass der Metallmantel eine stirnseitig offene Hülse ist, die von hinten auf den Geschosskem aufgezogen ist, wobei die Geschossspitze aus dem Metallmantel herausragt und am Geschoss- kern eine Einschnürung angeordnet ist, in die das offene stimseitige Mantelende hineinragt.According to the invention, this object is achieved in that the metal jacket is a sleeve which is open at the end and which is drawn onto the projectile core from behind, the projectile tip protruding from the metal jacket and a constriction being arranged on the projectile core, into which the open end-side jacket end projects.
Die Einschnürung hält so den Metallmantel fest und verhindert ein Abziehen desselben beim Eindringen in ein weiches Medium. Außerdem ist von großem Vorteil, dass das Mantelende hierdurch im Strömungsschatten der Geschossspitze liegt.The constriction thus holds the metal jacket in place and prevents it from being pulled off when penetrating into a soft medium. It is also of great advantage that the jacket end is thereby in the flow shadow of the top of the projectile.
In vorteilhafter Ausgestaltung der Erfindung besteht der Geschosskern aus härtbarem Stahl, Wolfram, Metallkarbiden, Sintermetallen oder Keramik.In an advantageous embodiment of the invention, the projectile core consists of hardenable steel, tungsten, metal carbides, sintered metals or ceramics.
Der Metallmantel ist bevorzugt aus Kupfer, einer Kupferlegierung, plattiertem Stahl, Weicheisen oder einer Zink-Zinn-Legierung hergestellt.The metal jacket is preferably made of copper, a copper alloy, plated steel, soft iron or a zinc-tin alloy.
BESTÄTSGÖMGSKOPIE Zweckmäßigerweise ist am Außenumfang des Geschosskerns zumindest eine Entlastungsrille angeordnet, wobei der Metallmantel im Bereich der Entlastungsrille am Geschosskem anliegen kann. Diese Entlastungsrillen können unterschiedliche Durchmesser und Breiten haben und über die gesamte Länge des Geschosses verteilt angeordnet sein.BESTÄTSGÖMGSKOPIE At least one relief groove is expediently arranged on the outer circumference of the projectile core, it being possible for the metal jacket to bear against the projectile core in the region of the relief groove. These relief grooves can have different diameters and widths and can be arranged distributed over the entire length of the projectile.
Eine Drallübertragung erfolgt durch die Geschossabschnitte, deren Durchmesser dem entsprechenden Geschosskaliber entsprechen.A swirl transmission takes place through the projectile sections, the diameters of which correspond to the corresponding projectile caliber.
Vorteilhaft weist der Boden des Metallmantels eine größere Dicke als die Wandstärke des zylindrischen Teils auf. Die Dicke des Bodens des Metallmantels kann jedoch auch kleiner oder gleich der Dicke der Wandstärke des zylindrischen Teils sein. Der Boden kann konvex oder konkav mit z. B. Radien zwischen 0,5 und 10 Kalibern oder flach sein. Alternativ kann der Boden des Metallmantels auch eine konkave oder konvexe Kegelspitze bilden.The bottom of the metal jacket advantageously has a greater thickness than the wall thickness of the cylindrical part. However, the thickness of the bottom of the metal jacket can also be less than or equal to the thickness of the wall thickness of the cylindrical part. The bottom can be convex or concave with z. B. Radii between 0.5 and 10 calibers or flat. Alternatively, the bottom of the metal shell can also form a concave or convex cone tip.
Die Heckform des Metallmantels kann konisch ausgebildet sein mit einem Winkel zwischen 0° und 90°. Das Heck ist der an den Boden angrenzende Bereich des Metallmantels.The rear shape of the metal jacket can be conical with an angle between 0 ° and 90 °. The rear is the area of the metal jacket adjacent to the floor.
Vorteilhafterweise ist der Geschosskem aufgeraut oder gerändelt, wodurch ein besserer Sitz des Geschossmantels bzw. Metallmantels auf dem Geschosskern erreicht ist.The projectile core is advantageously roughened or knurled, as a result of which a better fit of the projectile casing or metal casing on the projectile core is achieved.
Weitere Merkmale der Erfindung ergeben sich aus der einzigen Figur, die nachfolgend beschrieben ist.Further features of the invention result from the single figure, which is described below.
Mit dem Bezugszeichen 1 ist der Geschosskern bezeichnet, der aus härtbarem Stahl, Wolfram, Metallkorbiden, Sintermetallen oder Keramik besteht. Der Geschosskem 1 weist eine Geschossspitze 13 auf, die aus einem Metallmantel 2 herausragt. Der Metallmantel 2 besteht entweder aus Kupfer, einer Kufperlegierung, plattiertem Stahl, Weicheisen oder einer Zink- Zinn- Legierung. Es sind jedoch auch andere Metalle denkbar.Reference number 1 denotes the projectile core, which consists of hardenable steel, tungsten, metal basket, sintered metal or ceramic. The projectile core 1 has a projectile tip 13 which protrudes from a metal jacket 2. The metal jacket 2 consists of either copper, a copper alloy, plated steel, soft iron or a zinc-tin alloy. However, other metals are also conceivable.
Der Metallmantel 2 ist von hinten, also vom Heck 12 auf den Geschosskem 1 aufgezogen, wobei die Geschossspitze 13, wie schon erwähnt, freiliegt.The metal jacket 2 is drawn onto the projectile core 1 from the rear, that is to say from the rear 12, the projectile tip 13 being exposed, as already mentioned.
Zur dauerhaften Befestigung ist am Geschosskern 1 eine Einschnürung 4 angeordnet, in die das offene stirnseitige Mantelende 5 hineinragt. Hierdurch liegt das Mantelende 5 im Strömungsschatten der Geschossspitze 13.For permanent attachment, a constriction 4 is arranged on the projectile core 1, into which the open front-side jacket end 5 projects. As a result, the jacket end 5 lies in the flow shadow of the projectile tip 13.
Der Durchmesser der Geschossspitze ist kleiner als der Felddurchmesser.The diameter of the bullet tip is smaller than the field diameter.
Am Außenumfang des Geschosskems 1 ist in diesem speziellen Falle eine einzige Entlastungsrille 7 vorgesehen, wobei der Metallmantel 2 am Geschosskem 1 anliegt. Es kann jedoch auch eine Ausführungsform mit mehreren Entlastungsrillen gewählt werden, z. B. mit unterschiedlichen Breiten und Durchmessern.In this special case, a single relief groove 7 is provided on the outer circumference of the projectile core 1, the metal jacket 2 abutting the projectile core 1. However, an embodiment with several relief grooves can also be selected, e.g. B. with different widths and diameters.
Eine Drallübertragung erfolgt durch Geschossabschnitte deren Zylinderdurch- messer dem entsprechenden Geschosskaliber entsprechen (siehe z. B. Abschnitte 9).Swirl transmission takes place through projectile sections whose cylinder diameter corresponds to the corresponding projectile caliber (see eg section 9).
Der Boden 10 des Metallmantels 2 weist eine größere Dicke als die Wandstärke im zylindrischen Bereich auf. In diesem Ausführungsbeispiel ist der Boden flach ausgebildet. Er kann jedoch auch konvex oder konkav mit Radien zwischen 0,5 und 10 Kalibern ausgebildet sein. Die Bodenform kann auch als konvexe oder konkave Kegelspitze ausgeprägt sein.The bottom 10 of the metal jacket 2 has a greater thickness than the wall thickness in the cylindrical region. In this embodiment, the bottom is flat. However, it can also be convex or concave with radii between 0.5 and 10 calibers. The bottom shape can also be shaped as a convex or concave cone tip.
Das an den Boden angrenzende Heck 12 ist in der hier gezeigten Ausführungsform zylindrisch ausgebildet. Es kann jedoch auch konisch geformt sein.The rear 12 adjacent to the floor is cylindrical in the embodiment shown here. However, it can also have a conical shape.
Die Geschossspitze kann jede übliche Form aufweisen, d. h. spitz bis abgeflacht. The bullet tip can have any conventional shape, i. H. pointed to flattened.
