Description

Die Erfindung betrifft eine Patrone mit einem Geschoss und einer von hinten auf das Geschoss aufgezogenen Hülse mit einem Hülsenmund am vorderen Ende, wobei das Geschoss eine Spitze aufweist und diese Spitze heckseitig in ein umlaufendes vorderes Führungsband, welches den Geschossaußendurchmesser definiert, übergeht und unmittelbar angrenzend an dieses vordere Führungsband in Richtung Geschossboden ein sich in Axialrichtung des Geschosses erstreckender umlaufender Hülsenmundaufnahmeraum im Geschoss angeordnet ist, in den der Hülsenmund eingreift.The invention relates to a cartridge with a projectile and a rear-mounted on the bullet sleeve with a sleeve mouth at the front end, wherein the projectile has a tip and this tip on the rear side in a circumferential front guide band, which defines the projectile outer diameter passes, and immediately adjacent to this front guide band is arranged in the direction of the floor of the floor in the axial direction of the projectile extending circumferential sleeve mouth receiving space in the projectile, in which the sleeve mouth engages.

Ein derartiges Geschoss ist aus der EP 1 774 251 B1 bekannt. NL 7203827 offenbart eine Projektil-Hülsenverbindung für Munition.Such a projectile is from the EP 1 774 251 B1 known. NL 7203827 discloses a projectile sleeve connection for ammunition.

Der Erfindung liegt die Aufgabe zugrunde, eine Patrone nach dem Oberbegriff des Anspruchs 1 so zu verbessern, dass beim Schuss der rotationslose Geschossweg auf ein Minimum reduziert ist. Ebenso soll der Gasdruck frühzeitig aufgebaut werden. Außerdem soll unter anderem der Hülsenmund zum Geschoss hin gegen Feuchtigkeit jeglicher Form abgedichtet werden.The invention has for its object to improve a cartridge according to the preamble of claim 1 so that when shooting the non-rotating bullet path is reduced to a minimum. Likewise, the gas pressure should be built up early. In addition, among other things, the sleeve mouth to the floor towards moisture of any shape to be sealed.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention, this object is solved by the features of claim 1.

Dadurch, dass zwischen dem vorderen Führungsband und dem Hülsenmund ein sich in Axialrichtung des Geschosses erstreckender freiliegender Teilabschnitt des Hülsenmundaufnahmeraums angeordnet ist, d. h. der Hülsenmund füllt den Hülsenmundaufnahmeraum in Richtung Bug des Geschosses nicht vollständig aus, ist das vordere Führungsband nach vorne zur Spitze hin verlagert, wodurch der rotationslose Geschossweg auf ein Minimum reduziert ist. Außerdem ist
dadurch ein Aufnahmeraum geschaffen, der mit einem Abdichtungsmittel gefüllt werden kann, wodurch der Hülsenmund zum Geschoss hin gegen Feuchtigkeit jeglicher Form abgedichtet ist.
Characterized in that between the front guide band and the sleeve mouth an extending in the axial direction of the projectile exposed portion of the Sülsenmundaufnahmeraums is arranged, ie the sleeve mouth does not completely fill the Sülmundmundaufnahmeraum towards the bow of the projectile, the front guide band is displaced forward toward the top, whereby the rotationless bullet path is reduced to a minimum. Besides that is
thereby creating a receiving space that can be filled with a sealing agent, whereby the sleeve mouth is sealed to the projectile against moisture of any shape.

Erfindungsgemäss ist der freiliegende Teilabschnitt des Hülsenmundaufnahmeraums mit einem Abdichtungsmittel, wie z.B. ein Lack abgedichtet.According to the invention, the exposed section of the sleeve mouth receiving space is provided with a sealing means, such as e.g. a varnish sealed.

In einer Ausführungsform geht die Geschossspitze ogival oder kegelig über eine oder mehrere Formen in das vordere Führungsband, d.h. auf den Geschossaußendurchmesser über. Optimaler Weise hat die Übergangsform von Spitze zum Führungsband am Führungsband eine Kegelform im Winkel des Übergangskonusses des Patronenlagers. Der damit erreichte Anstieg auf den Geschossaußendurchmesser reduziert den rotationslosen Geschossweg und baut den Gasdruck auf. Die Kegelform am Führungsband bewirkt die Zentrierung des Geschosses zur Laufseelenachse. Eine so erzeugte Zentrierung bewirkt eine Präzisionsverbesserung.In one embodiment, the bullet tip passes ogivally or conically over one or more shapes into the leading guide band, i. on the bullet outside diameter over. Optimally, the transitional shape of the tip to the guide band on the guide band has a conical shape at the angle of the transition cone of the cartridge chamber. The increase to the outside diameter of the projectile thus reduces the non-rotating projectile path and builds up the gas pressure. The conical shape on the guide belt causes the centering of the projectile to Laufseelenachse. A centering thus produced causes a precision improvement.

Der freiliegende Teilabschnitt des Hülsenmundaufnahmeraums geht erfindungsgemäss geradlinig in das vordere Führungsband über und verläuft in einem Winkel kleiner gleich 16 Grad zur Geschossachse hin. Aus aerodynamischen gründen wird dieser Winkel von ≤ 16° zur Geschossachse bevorzugt. Eine Ausführungsform ist dadurch gekennzeichnet, dass von der radial tiefsten Stelle im Hülsenmundaufnahmeraum, d.h. dem Feldmaßdurchmesser oder kleiner, die Geschossform in Richtung Heck konkav, konvex oder geradlinig, über ein oder mehrere Formen, auf den Geschossdurchmesser oder kleiner übergeht. Das vordere Führungsband im Geschossaußendurchmesser ermöglicht eine kleinere Gestaltung des hintern Geschossteils, da dieser somit nicht zum Druckaufbau benötigt wird. Außerdem reduziert sich so auch die Laufbelastung (Reibungswiederstände und damit verbundene Lauferwärmung, Laufablagerungen). Die Geschossform ist bestenfalls so gestaltet, dass sie sich zum Abdichten des Hülsenmundes zum Geschoss und zum Kneifen des Hülsenmundes eignet.The exposed portion of the sleeve mouth receiving space according to the invention goes straight into the front guide band and extends at an angle less than or equal to 16 degrees to the projectile axis. For aerodynamic reasons, this angle of ≤ 16 ° to the projectile axis is preferred. An embodiment is characterized in that from the radially lowest point in the sleeve mouth receiving space, ie the Feldmaßdurchmesser or smaller, the projectile shape in the direction of the rear concave, convex or rectilinear, over one or more forms, on the projectile diameter or smaller passes. The front guide band in the bullet outside diameter allows for a smaller design of the rear bullet, since this is not required for pressure build-up. It also reduces the running load (Friction resistance and associated warming, running deposits). At best, the bullet shape is designed to be suitable for sealing the mouth of the mouth to the bullet and for pinching the mouth of the bullet.

In einer Ausgestaltung ist im Heck des Geschosses ein Aufnahmeraum angeordnet, in dem sich ein Stoff befindet, der bei Initiierung eine Leuchtspur erzeugt. Es handelt sich dann um ein Leuchtspurgeschoss bzw. eine Leuchtspur-Patrone.In one embodiment, a receiving space is arranged in the rear of the projectile, in which there is a substance that generates a tracer path upon initiation. It is then a tracer or a tracer cartridge.

In einer Ausführungsform ist im Geschoss eine zur Geschossachse koaxiale Bohrung angeordnet, die zur Geschossspitze offen ist und ist in der Bohrung ein Geschosskern aus Wolfram oder Wolframkarbid angeordnet und ist die Bohrung durch ein Geschossspitzeneinsatz aus Titan oder Zirkonium verschlossen, wobei der Außenmantel des Geschossspitzeneinsatzes ein Teil der Spitze des Geschosses ist. Es handelt sich dann um ein API Geschoss (Armor Piercing Incendiary Geschoss = Panzerbrandgeschoss) bzw. API- Patrone.In one embodiment, a bullet axis coaxial to the bullet axis is disposed in the bullet, which is open to the projectile nose and in the bore a bullet core of tungsten or tungsten carbide is disposed and the bore is closed by a bullet tip insert made of titanium or zirconium, wherein the outer shell of the bullet tip insert a part the top of the projectile is. It is then an API bullet (Armor Piercing Incendiary projectile = Panzerbrand) or API cartridge.

Grundsätzlich ist die Ausführungsform mit dem nach vorn verlagertem Führungsband auf weitere Geschossarten übertragbar. Weitere Geschossarten sind z.B. AP-Geschosse (Armor Piercing = panzerbrechende Geschosse), Teilzerlegungsgeschosse, Vollmantelgeschosse, Monolithen, Deformationsgeschosse und weitere.In principle, the embodiment with the guide band displaced to the front can be transferred to further types of projectile. Other bullet types are e.g. AP projectiles (armor piercing = armor-piercing projectiles), partial separation projectiles, full-shell projectiles, monoliths, deformation projectiles and others.

Nachfolgend wird die Erfindung anhand von Figuren näher erläutert.The invention will be explained in more detail with reference to figures.

Figur 1a zeigt eine erfindungsgemäße Patrone 10 und Figur 1b einen Ausschnitt A von Figur 1a vergrößert. Figur 2 zeigt das Geschoss 11 gemäß Figuren 1a und 1b, jedoch ohne Hülse 12. Figur 3 zeigt im Schnitt ein erfindungsgemäße Patrone 10, eingesetzt in einen Lauf 23 einer Waffe. Gleiche Bezugszeichen zeigen auch den gleichen Gegenstand und dies in allen Figuren. FIG. 1a shows a cartridge 10 according to the invention and FIG. 1b a section A of FIG. 1a increased. FIG. 2 shows the projectile 11 according to FIGS. 1a and 1b but without sleeve 12. FIG. 3 shows in section a cartridge 10 according to the invention, inserted into a barrel 23 of a weapon. Like reference numerals also show the same subject matter and in all figures.

Die Patrone 10 besteht aus einem Geschoss 11 und einer von hinten auf das Geschoss 11 aufgezogenen Hülse 12 mit einem Hülsenmund 13 am vorderen Ende, wobei das Geschoss 11 eine Spitze 1 aufweist und diese Spitze 1 heckseitig in ein umlaufendes vorderes Führungsband 4, welches den Geschossaußendurchmesser definiert, übergeht. Unmittelbar angrenzend an dieses vordere Führungsband 4 in Richtung Geschossboden 14 ist ein sich in Axialrichtung des Geschosses 11 erstreckender umlaufender Hülsenmundaufnahmeraum 15 im Geschoss 11 angeordnet, in den der Hülsenmund 13 eingreift. Zwischen dem vorderen Führungsband 4 und dem Hülsenmund 13 ist ein sich in Axialrichtung des Geschosses 11 erstreckender freiliegender Teilabschnitt 16 des Hülsenmundaufnahmeraums 15 angeordnet. Der Hülsenmund 13 füllt daher den Hülsenmundaufnahmeraum 15 in Richtung Bug des Geschosses 11 nicht vollständig aus. Der Hülsenmund 13 füllt also nur einen Teil des Hülsenmundaufnahmeraums 15 aus und der verbleibende Teil ist außerhalb der Hülse 12 angeordnet.The cartridge 10 consists of a projectile 11 and a rearwardly mounted on the projectile 11 sleeve 12 with a sleeve mouth 13 at the front end, wherein the projectile 11 has a tip 1 and this tip 1 rear side in a circumferential front guide band 4, which the projectile outer diameter defined, passes. Immediately adjacent to this front guide band 4 in the direction of the floor 14 is a projecting in the axial direction of the projectile 11 circumferential sleeve mouth receiving space 15 in the projectile 11, in which the sleeve mouth 13 engages. Between the front guide band 4 and the sleeve mouth 13, an exposed partial section 16 of the sleeve mouth receiving space 15 is arranged which extends in the axial direction of the projectile 11. The sleeve mouth 13 therefore does not completely fill the sleeve mouth receiving space 15 in the direction of the nose of the projectile 11. The sleeve mouth 13 thus fills only a part of the sleeve mouth receiving space 15 and the remaining part is arranged outside the sleeve 12.

Durch das so nach vorne verlagerte vordere Führungsband 4, im Folgenden auch Geschossaußendurchmesser genannt, am Geschoss 11, wird der rotationslose Geschossweg beim Schuss auf ein Minimum reduziert. Ebenso ist durch das vordere Führungsband 4 der Gasdruck frühzeitig aufgebaut, wodurch die Möglichkeit entsteht, den Bereich hinter dem vorderen Führungsband 4 im Durchmesser kleiner zu gestalten. Eine Verringerung des Durchmessers reduziert die Geschossreibung im Lauf 23. Durch weniger Reibung entsteht weniger Wärmeenergie. Die Erwärmung des Laufes 23 wird somit zeitlich verzögert. Die Präzision wird erhöht und bleibt länger erhalten. Auf Grund der reduzierten Geschossreibung steigt die Geschwindigkeit, was eine gestreckte Flugbahn erzeugt. Durch den freiliegenden Teilabschnitt 16 des Hülsenmundaufnahmeraums 15 kann der Hülsenmund 13 und ein Bereich 7 des Hülsenmundaufnahmeraums 15 leicht gegen Feuchtigkeit jeglicher Form abgedichtet werden, zum Beispiel durch einen Lack in diesem freiliegenden Teilabschnitt 16 des Hülsenmundaufnahmeraums 15.As a result of the forward guide band 4, which is also referred to below as the projectile outer diameter, on the projectile 11, the rotationally free projectile path during firing is reduced to a minimum. Likewise, the gas pressure is built up early by the front guide strip 4, whereby the possibility arises to make the area behind the front guide strip 4 smaller in diameter. Reducing the diameter reduces bullet friction in run 23. Less friction results in less heat energy. The heating of the barrel 23 is thus delayed in time. The precision is increased and retained longer. Due to the reduced bullet friction, the speed increases, creating a stretched trajectory. By the exposed portion 16 of the sleeve mouth receiving space 15 of the sleeve mouth 13 and a portion 7 of the sleeve mouth receiving space 15 can be easily sealed against moisture of any shape, for example by a paint in this exposed portion 16 of the sleeve mouth receiving space 15th

Die Geschossspitze 1 kann rund, flach oder spitz sein.The bullet tip 1 can be round, flat or pointed.

Die Geschossspitze 1 verläuft ogival 2 oder kegelig über ein oder mehrere Formen, wie konkav, konvex oder geradlinig 3 bis zum Geschossaußendurchmesser, bzw. bis zum vorderen Führungsband 4. Optimaler Weise hat die Übergangsform von Spitzte zum Führungsband am Führungsband eine Kegelform im Winkel des Übergangskonusses des Patronenlagers. Die Kegelform am Führungsband bewirkt die Zentrierung des Geschosses zur Laufseelenachse. Eine so erzeugte Zentrierung bewirkt zusätzlich eine Präzisionsverbesserung.The projectile nose 1 extends ogival 2 or conically over one or more forms, such as concave, convex or rectilinear 3 to the projectile outer diameter, or to the front guide 4. Optimally, the transition form of tip to the guide band on the guide band has a cone shape at the angle of the transition cone the cartridge warehouse. The conical shape on the guide belt causes the centering of the projectile to Laufseelenachse. A centering thus produced additionally causes a precision improvement.

Der damit erreichte Anstieg auf den Geschossaußendurchmesser soll den rotationslosen Geschossweg reduzieren und den Gasdruck aufbauen. Der Geschossaußendurchmesser bzw. das vordere Führungsband 4 wird in jedem Kaliber definiert über den größten zulässigen Geschossdurchmesser. In CIP Mitgliedsländern ist dies der Wert für "G1" bei "Patrone Maxi."The increase to the outside diameter of the projectile is supposed to reduce the non-rotating projectile path and build up the gas pressure. The bullet outside diameter or front guide band 4 is defined in each caliber over the largest permissible bullet diameter. In CIP member countries, this is the value for "G1" on "Patrons Maxi."

Abweichend von dem oben genannten Außendurchmesser wird im Militär- und Behörden-Bereich dessen definierter maximal zulässiger Geschossaußendurchmesser verwendet. Die Toleranzbereich am vorderen Führungsband 4 liegt bei - 0.1 mm zum zulässigen Geschossdurchmesser.Deviating from the above-mentioned outside diameter, the defined maximum permissible projectile outside diameter is used in the military and government sector. The tolerance range at the front guide band 4 is - 0.1 mm to the permissible projectile diameter.

Der Geschossaußendurchmesser bzw. die axiale Ausdehnung des vorderen Führungsbandes wird nur kurzzeitig gehalten und verläuft aus aerodynamischen Gründen langsam geradlinig 5 auslaufend, auf einen Durchmesser entsprechend Feldmaßdurchmesser 6 oder kleiner.The projectile outer diameter or the axial extent of the front guide strip is held only briefly and runs for aerodynamic reasons slowly straight 5 expiring, to a diameter corresponding to Feldmaßdurchmesser 6 or smaller.

Der Abstand zwischen dem vordersten Führungsbandes 4 und dem Feldmaßdurchmesser 6 richtet sich nach dem Kaliber mit unterschiedlichen übergangslängen. Das vordere Führungsband 4 ist jedoch so positioniert, dass möglichst wenig bis kein rotationsloser Geschossweg vorhanden ist. Dabei ist ein Abstand zwischen Hülsenmund 13 und dem vordersten Führungsband 4 wesentlich.The distance between the foremost guide belt 4 and the Feldmaßdurchmesser 6 depends on the caliber with different transition lengths. However, the front guide band 4 is positioned so that as possible Little to no rotating bullet path is available. In this case, a distance between the sleeve mouth 13 and the foremost guide band 4 is essential.

Der Feldmaßdurchmesser 6 am tiefsten Punkt des Hülsenmundaufnahmeraums 15 wird in jedem Kaliber definiert. In CIP Mitgliedsländern ist dies der Wert für "F" bei "Patronenlager Mini." Abweichend von dem oben genannten Feldmaßdurchmesser 6 wird im Militär- und Behörden- Bereich dessen minimal zulässiges Feldmaß verwendet. Die auslaufende Form kann konkav, konvex oder geradlinig verlaufen. Aus aerodynamischen Gründen wird ein Winkel 9 von ≤ 16° zur Geschossachse 17 bevorzugt. Bei Radien wird der Winkel der entstehenden Geraden zwischen dem vorderen Führungsband 4 und dem Feldmaßdurchmesser 6 verwendet.The Feldmaßdurchmesser 6 at the lowest point of the sleeve mouth receiving space 15 is defined in each caliber. In CIP member countries, this is the value for "F" in "Cartridge Mini." Deviating from the above-mentioned field diameter 6, the minimum permissible field size is used in the military and government sector. The expiring form can be concave, convex or rectilinear. For aerodynamic reasons, an angle 9 of ≦ 16 ° to the projectile axis 17 is preferred. For radii, the angle of the resulting straight line between the front guide band 4 and the Feldmaßdurchmesser 6 is used.

Vom Feldmaßdurchmesser 6 oder kleiner, verläuft die Geschossform in Richtung Heck konkav, konvex oder geradlinig 7 (siehe Figur 1b), über ein oder mehrere Formen, auf den Geschossdurchmesser. Die Geschossform 7 ist bestenfalls so gestaltet das sie sich zum Abdichten des Hülsenhalses 24 und zum Kneifen der Hülse 12 eignet.From the field diameter 6 or smaller, the projectile shape is concave, convex or straight 7 toward the rear (see FIG. 1b ), via one or more shapes, on the bullet diameter. The bullet mold 7 is at best designed so that it is suitable for sealing the sleeve neck 24 and for pinching the sleeve 12.

Das Geschoss 11 ist im Bereich des Hülsenhalses 24 zylindrisch oder mit hinteren Führungsbändern 8 versehen.The projectile 11 is cylindrical or provided with rear guide bands 8 in the region of the sleeve neck 24.

In einem Aufnahmeraum 19 im Heck des Geschosses 11 kann ein Stoff enthalten sein, der eine Leuchtspur erzeugt. In diesem Fall spricht man von einem Leuchtspurgeschoss.In a receiving space 19 in the rear of the projectile 11, a substance may be contained, which generates a tracer. In this case we speak of a tracer bullet.

Bevorzugt ist im Geschoss 11 (siehe Figur 3) eine zur Geschossachse 17 koaxiale Bohrung 20 angeordnet, die zur Geschossspitze 1 offen ist und ist in der Bohrung 20 ein Geschosskern 21 aus Wolfram oder Wolframkarbid angeordnet und ist die Bohrung 20 durch einen Geschossspitzeneinsatz 22 aus Titan oder Zirkonium verschlossen, wobei der Außenmantel des Geschossspitzeneinsatzes 22 ein Teil der Spitze 1 des Geschosses 11 ist.Preferably in the projectile 11 (see FIG. 3 ) arranged a coaxial bore 17 to the projectile axis, which is open to the projectile nose 1 and is disposed in the bore 20, a projectile core 21 made of tungsten or tungsten carbide and the bore 20 is closed by a bullet tip insert 22 made of titanium or zirconium, wherein the outer shell of the bullet tip insert 22 is part of the tip 1 of the projectile 11.
