Abstract

The invention relates to a training cartridge for an automatic rapid-fire weapon. Said training cartridge ( 1 ) has a central channel ( 4 ) running therethrough which accommodates a propellant charge ( 6 ) in the rear area of the cartridge ( 1 ) and is closed at the rear by a detonator charge ( 7 ) for the propellant charge ( 6 ). The training cartridge and weapon barrel are configured in such a way that no live ammunition can be fired from said weapon barrel. The channel which is open at the cartridge tip is preferably used during the firing of the training cartridge to receive a mandrel ( 28 ) of a gas choke ( 22 ) which is mounted in the weapon barrel ( 21 ). The propulsion gases which escape through the opening ( 8 ) at the cartridge tip propel the training cartridge backwards towards the weapon bolt and expel said cartridge from said bolt of the rapid-fire weapon. The bolt is simultaneously primed for the next shot.

Description

Die Erfindung bezieht sich auf ein Übungsgeschoss mittleren Kalibers für eine automatische Schnellfeuerwaffe sowie auf ein System aus einem solchen Übungsgeschoss und einem Waffenrohr.The invention relates to a middle practice floor Caliber for an automatic rapid-fire weapon as well as a System consisting of such a practice floor and a weapon barrel.

Für Übungszwecke ist es erwünscht, über eine Übungs- bzw. Manövermunition zu verfügen, die in ihren Eigenschaften zumindest im Bereich der Schnellfeuerwaffe der scharfen Munition entspricht, damit alle Funktionen ungestört ablaufen. Hierbei sollten keine wesentlichen Änderungen an der Waffe vorgenommen werden müssen. Gleichzeitig sollten das Übungsgeschoss und ein etwa notwendiger Umbausatz für die Waffe so ausgebildet sein, dass scharfe Munition während des Schießens mit Manövermunition nicht versehentlich abgeschossen werden kann.For exercise purposes, it is desirable to use an exercise or To have maneuvering ammunition in their properties at least in the area of the rapid firearm of the sharp Ammunition corresponds so that all functions run undisturbed. There should be no significant changes to the weapon must be made. At the same time Practice floor and any necessary conversion kit for the Weapon should be designed so that live ammunition during the Shooting with maneuvering ammunition not accidentally fired can be.

Aus der US-A-5438907 ist ein Übungsgeschoss bekannt, das einen durchgehenden zentralen Kanal aufweist, der im Heckbereich des Geschosses eine Treibladung enthält :und am Heck durch eine Anzündladung für die Treibladung abgeschlossen ist. Der Kanal ist an der Geschossspitze offen. Das zugeordnete Waffenrohr weist einen Dorn auf, der an einem in das Waffenrohr einzusetzenden Einsatz befestigt ist und bei vollständig in das Waffenrohr eingeschobenem Übungsgeschoss in das offene Ende des Kanales des Geschosses taucht. Dadurch wird ein Einsetzen eines scharfen Geschosses, das keinen vorne offenen Kanal aufweist, verhindert.From US-A-5438907 a practice floor is known that one Continuous central channel which in the rear area of the Projectile contains a propellant charge: and at the rear through a Ignition charge for the propellant charge is complete. The channel is open at the top of the floor. The assigned gun barrel has a thorn on one in the gun barrel insert to be used and when completely in the weapon barrel inserted training floor in the open End of the channel of the projectile dives. This will make a Insert a sharp bullet that does not have an open front Channel has prevented.

Nach der Zündung der Treibladung des Geschosses breiten sich die Treibgase vehement in Richtung auf das offene Ende des zentralen Kanales des Übungsgeschosses aus, wobei sich in dem relativ kleinen Raum zwischen Treibladung und Dornspitze rasch ein hoher Gasdruck aufbaut, der das Geschoss zurück in das Waffenschloss treibt und dieses weiterschaltet.After firing the propellant charge of the projectile spread the propellant gases vehemently towards the open end of the central channel of the practice floor, whereby in the relatively small space between the propellant charge and the tip of the mandrel quickly a high gas pressure builds up which pushes the projectile back into the Gun lock drives and switches it on.

Als weiterer Stand der Technik sei auf die DE-A-37 33 216 oder die DE-A-14 53 827 verwiesen, wobei allerdings bei dem System gemäß der letzteren Schrift jedoch nicht sichergestellt ist , dass versehentlich auch scharfe Munition verschossen wird.Another state of the art is on DE-A-37 33 216 or referred to DE-A-14 53 827, but with the system however, according to the latter, it is not guaranteed that live ammunition is accidentally fired.

Der Erfindung liegt die Aufgabe zugrunde, ein Übungsgeschoss, insbesondere für großkalibrige Schnellfeuerwaffen, zur Verfügung zu stellen, das in der Funktion zuverlässig ist, einfach aufgebaut ist, nur aus wenigen Teilen besteht und daher kostengünstig hergestellt werden kann.The invention has for its object a practice floor, especially for large caliber rapid firearms, for To make available that is reliable in function, is simple, consists of only a few parts and can therefore be manufactured inexpensively.

Diese Aufgabe ist für ein Übungsgeschoss durch die Merkmale des Anspruches 1 gelöst.This task is for a practice floor by the characteristics of claim 1 solved.

Das Übungsgeschoss kann im wesentlichen aus vier Teilen aufgebaut werden, nämlich einem Geschossboden, einem in den Geschossboden eingefügten, in Längsrichtung des Geschosses verlaufenden zentralen Rohr zur Aufnahme der Treibladung, einem in den Geschossboden eingesetzten Anzündhütchen zur Zündung der Treibladung und einem einstückigen Geschosskörper, der vom Geschossboden ausgehend das zentrale Rohr umhüllt, die an der Spitze des Geschosses gelegene Öffnung des zentralen Rohres jedoch freilässt. Der Geschosskörper wird hierbei bevorzugt aus gespritztem Kunststoff hergestellt. Der Geschossboden ist üblicherweise ein Metallteil und vorzugsweise aus Aluminium oder Stahl; das zentrale Rohr ist bevorzugt aus Stahl, um den bei der Zündung der Treibladung auftretenden Gasdrücken standzuhalten.The practice floor can essentially consist of four parts be built, namely one floor, one in the Floor inserted, in the longitudinal direction of the floor running central tube for receiving the propellant charge, a primer plug inserted in the floor Ignition of the propellant charge and a one-piece projectile body, which envelops the central tube starting from the floor, the opening of the central at the top of the floor Rohres however leaves free. The projectile body is hereby preferably made of injection molded plastic. The Floor is usually a metal part and preferably made of aluminum or steel; is the central tube preferably made of steel in order to ignite the propellant charge to withstand occurring gas pressures.

Es ist ferner möglich, am bugseitigen Ende der Treibladung diese mit einer zerstörbaren Kappe oder einer Berstscheibe abzudecken und/oder noch eine Düse oder Düsenanordnung in dem zentralen Rohr vorzusehen, wodurch die Entwicklung des Gasdruckes in dem Waffenrohr nach der Zündung der Treibladung weiter optimiert werden kann.It is also possible at the bow end of the propellant charge this with a destructible cap or a rupture disc cover and / or another nozzle or nozzle arrangement in the provide central tube, thereby the development of the Gas pressure in the gun barrel after the propellant charge is ignited can be further optimized.

Bei einem Übungsgeschoss gemäß der Erfindung wird beim simulierten Abschuss kein unmittelbarer Gasdruck hinter dem Übungsgeschoss aufgebaut; vielmehr werden die Treibgase der Treibladung durch entsprechende Führung in dem Geschoss über dessen Spitze freigegeben, so dass sich zwischen der Geschossspitze und dem Einsatz in dem Waffenrohr ein Gasdruck aufbaut, der das Übungsgeschoss zur Betätigung des Schlosses in dieses zurückdrückt.In a practice floor according to the invention, the simulated launch no immediate gas pressure behind the Practice floor built up; rather the propellants are the Propellant charge through appropriate guidance in the floor above its tip released, so that between the Bullet tip and use in the gun barrel a gas pressure builds up the practice floor to operate the lock pushes back into this.

Bei entsprechender Dimensionierung von Dorn, zentralem Kanal und Gasdrossel können im wesentlichen die gleichen Erscheinungen wie bei einem scharfen Schuss erreicht werden, d.h. Blitz-, Knall- und Rauchentwicklung.With appropriate dimensioning of mandrel, central channel and gas throttle can be essentially the same Appearances like a sharp shot are achieved i.e. Lightning, bang and smoke development.

Die Erfindung ist in einem Ausführungsbeispiel anhand der Zeichnung näher erläutert. In dieser stellen dar:

Wie aus Figur 1 ersichtlich, weist das Übungsgeschoss 1 einen Geschossboden 2 aus Aluminium, ein in ein zentrales Gewinde 3 des Geschossbodens eingeschraubtes zentrales Stahlrohr 4 und einen vom Geschossboden ausgehenden kappenförmigen Geschosskörper 5 aus, der ein einstückiges gespritztes Kunststoffteil ist und bis zu dem vorderen Ende des Stahlrohres 4 reicht. Die heckseitige Hälfte des Stahlrohres 4 ist mit einer Treibladung 6 gefüllt, die über ein in das Heck des Geschosses in den Geschossboden eingesetztes Anzündhütchen 7 mit Hilfe eines Schlagbolzens zündbar ist. Das zentrale Stahlrohr 4 weist an seiner Spitze eine freie Öffnung 8 auf, an deren Rand sich der erwähnte Geschosskörper 5 unmittelbar anschließt.As can be seen from Figure 1, the practice floor 1 has one Floor 2 made of aluminum, one in a central thread 3 screwed central steel tube 4 and a cap-shaped starting from the floor Projectile body 5 made of a one-piece injection molded Is plastic part and up to the front end of the Steel tube 4 is enough. The rear half of the steel tube 4 is filled with a propellant charge 6, which is in the rear primer inserted into the floor of the floor 7 is ignitable with the help of a firing pin. The central Steel tube 4 has a free opening 8 at its tip, on the edge of which the projectile body 5 mentioned is located directly followed.

Wie in Figur 1 angedeutet, kann das zentrale Stahlrohr 4 etwa in seiner Mitte durch eine Trennwand 9 unterbrochen werden, in der eine Düse 10 vorgesehen ist, die den Raum der Treibladung 6 mit dem leeren Raum des Stahlrohres bis zur Öffnung 8 verbindet.As indicated in Figure 1, the central steel tube 4 can be interrupted in the middle by a partition 9, in which is provided a nozzle 10, the space of the propellant charge 6 with the empty space of the steel pipe up to the opening 8 combines.

In Figur 2 ist mit 21 ein Waffenrohr einer nicht weiter dargestellten automatischen Schnellfeuerwaffe bezeichnet. In dieses Waffenrohr wird für den Übungsbetrieb vom vorderen Ende aus ein Einsatz 22 eingeschoben, wobei dieser Einsatz aus einem Rohr 23 und einem Kolben 24 besteht. Das Rohr 23 liegt bündig an der Innenseite des Waffenrohres 21 an und ist an dem dem Kolben 24 gegenüberliegenden Ende mit einem Anschlag 25 versehen, der an dem vorderen Rand des Waffenrohres 21 anliegt. Das Rohr 23 wird durch eine Überwurfmutter 26 mit einer zentralen Öffnung 27 gehalten, die in ein Außengewinde des Waffenrohres 21 eingeschraubt wird.In FIG. 2, a weapon barrel is no further at 21 Automatic Rapid Firearm shown. In this gun barrel is used for training operations from the front end inserted from an insert 22, this insert from a tube 23 and a piston 24. The tube 23 is flush on the inside of the gun barrel 21 and is on the end opposite piston 24 with a stop 25 provided at the front edge of the gun barrel 21st is applied. The tube 23 is with a union nut 26 a central opening 27 held in an external thread the gun barrel 21 is screwed.

Der Kolben 24 weist einen zentralen Dorn 28 auf, dessen Außendurchmesser kleiner als der lichte Durchmesser des Stahlrohres 4 ist. Die Länge des Dornes entspricht maximal der Distanz zwischen der Öffnung 8 des Stahlrohres 4 und der Trennwand 9 in dem Stahlrohr 4. The piston 24 has a central mandrel 28, the Outside diameter smaller than the inside diameter of the Steel tube 4 is. The length of the mandrel corresponds to the maximum Distance between the opening 8 of the steel tube 4 and the Partition 9 in the steel tube 4th

In dem Kolben 24 sind um den zentralen Dorn 28 herum noch einige Überströmkanäle 29 vorgesehen.In the piston 24 there are still around the central mandrel 28 some overflow channels 29 are provided.

In den Figuren 2 bis 7 ist der Funktionsablauf der automatischen Schnellfeuerwaffe bei der Verwendung mit dem Übungsgeschoss dargestellt.In Figures 2 to 7, the functional flow is automatic rapid firearm when used with the Practice floor shown.

In Figur 2 ist der Zeitpunkt gezeigt, in dem das Übungsgeschoss 1 von dem Verschluss in das Waffenrohr 21 geladen wird: der zentrale Dorn 28 des Einsatzes 22 dringt hierbei in das zentrale Stahlrohr 4 ein.FIG. 2 shows the time at which the Practice floor 1 from the breech in the barrel 21 is loaded: the central mandrel 28 of the insert 22 penetrates here in the central steel tube 4.

In Figur 3 hat das Übungsgeschoss 1 den Verschluss verlassen und befindet sich vollständig in dem Waffenrohr 21; in diesem Moment wird das Anzündhütchen 7 durch einen Schlagbolzen des Verschlusses gezündet. Praktisch gleichzeitig wird auch die Treibladung 6 gezündet.In Figure 3, practice floor 1 has left the lock and is completely in the gun barrel 21; in this Moment is the primer 7 by a firing pin Ignition locked. That becomes practically at the same time Propellant charge 6 ignited.

Die beim Abbrennen der Treibladung erzeugten, in Figur 4 schematisch dargestellten Treibladungsgase 31 breiten sich in Richtung auf die Geschossspitze aus, wobei diese Ausbreitung durch den Spalt zwischen dem zentralen Dorn 28 und der lichten Weite des zentralen Stahlrohres 4 gedrosselt erfolgt. Die Gase strömen in den einen Gasraum 30 bildenden Zwischenraum zwischen dem vorderen Ende der Treibladung und der Spitze des Dornes; hier entwickelt sich ein hoher Gasdruck, durch den, wie in Figur 4 durch den Pfeil angedeutet, das Übungsgeschoss bereits wieder in Richtung des Schlosses zurückbewegt wird.The generated during the burning of the propellant charge in Figure 4 propellant gases 31 shown schematically spread in Direction to the top of the projectile, this spread through the gap between the central mandrel 28 and the clear one Width of the central steel tube 4 is throttled. The gases flow into the intermediate space forming a gas space 30 between the front end of the propellant and the tip of the arbor; a high gas pressure develops here, through which as indicated in Figure 4 by the arrow, the practice floor is already being moved back towards the castle.

Durch den Spalt zwischen Dorn 28 und Stahlrohr 4 treten aus der freien Öffnung 8 des Stahlrohres die Treibgase vermehrt in den Gasraum 30 zwischen der Geschossspitze und dem Kolben 24 aus, so dass der Druck dieser Treibgase, wie in Figur 5 angedeutet, nunmehr auf die volle Stirnfläche des Geschosses wirkt und dieses weiter nach rückwärts in das Schloss zurückbeschleunigt. Die Treibgase strömen jetzt auch durch die Überströmkanäle 29 und treten dann aus der zentralen Öffnung 27 der Überwurfmutter 26 ins Freie aus.Exit through the gap between mandrel 28 and steel tube 4 the free opening 8 of the steel pipe increases the propellant gases in the gas space 30 between the projectile tip and the piston 24 off, so that the pressure of these propellant gases, as in FIG indicated, now on the full face of the floor acts and this backwards into the lock accelerated back. The propellants are now flowing through the Overflow channels 29 and then emerge from the central opening 27 of the union nut 26 from the outside.

In dem in Figur 6 gezeigten Zeitpunkt ist das Übungsgeschoss vollständig von dem zentralen Dorn 28 geglitten und in das Schloss zurückgeführt, aus dem es anschließend ausgeworfen wird.At the time shown in Figure 6 is the practice floor completely slid from the central mandrel 28 and into the Castle returned from which it was subsequently ejected becomes.

Durch Optimierung der Dimensionen von Durchmesser des Dornes 28, lichtem Durchmesser des Stahlrohres 4, Anzahl und Durchmesser der Überströmkanäle 29 sowie Distanz des Kolbens 24 des Einsatzes 22 und gegebenenfalls durch die Anordnung und Dimensionierung der Düse 10 in der Trennwand 9 können der Druckaufbau in dem Waffenrohr 21 zum Zurücktreiben des Übungsgeschosses in das Schloss optimiert werden. Durch den Aufbau des Gasdruckes zunächst in einem kleinen Hochdruckraum zwischen Treibladung und Spitze des Dornes und dem anschließenden Aufbau eines weiteren Druckraumes zwischen dem Kolben und der gesamten Geschossquerschnittsfläche können auch die für die Funktion des Schlosses der automatischen Waffe notwendigen hohen Kräfte erreicht werden. Ebenso ist es möglich, durch die angegebene Dimensionierung sowie natürlich auch die Zusammensetzung der Treibladung an der Mündung des Waffenrohres 21 beim simulierten Abschuss die bei einer scharfen Munition auftretenden Erscheinungen nachzubilden, d.h. Blitz-, Knall- und Raucheffekte.By optimizing the dimensions of the diameter of the mandrel 28, clear diameter of the steel tube 4, number and Diameter of the overflow channels 29 and distance of the piston 24 of the insert 22 and possibly by the arrangement and Dimensioning of the nozzle 10 in the partition 9 can Pressure build-up in the gun barrel 21 to drive back the Practice floor in the castle can be optimized. By the The gas pressure is initially built up in a small high-pressure room between propellant charge and tip of the mandrel and the subsequent construction of a further pressure space between the Pistons and the entire floor area can also for the function of the lock of the automatic weapon necessary high forces can be achieved. It is the same possible due to the specified dimensioning and of course also the composition of the propellant charge at the mouth of the Gun barrel 21 in the simulated launch the one to reproduce appearances of live ammunition, i.e. Lightning, bang and smoke effects.

In Figur 7 ist ein modifiziertes Übungsgeschoss dargestellt. Für gleiche Elemente wie bei dem Ausführungsbeispiel gemäß Figur 1 sind gleiche Bezugszeichen verwendet. Bei diesem Geschoss ist die heckseitig gelegene Treibladung 6 durch eine zerstörbare Abdeckkappe oder eine Berstscheibe 71 abgedeckt; die Trennwand mit der Düse fehlt. Im Bugbereich ist der Durchmesser des Übungsgeschosses verringert, so dass sich ein Anschlag 72 ergibt, der dann an einem korrespondierenden Anschlag 73 des hier schematisch angedeuteten Waffenrohres 21 anliegt. Das Waffenrohr in diesem bugseitigen Bereich des Geschosses weist einen geringeren Durchmesser auf als im heckseitigen Bereich des Geschosse. Scharfe Munition, die im Bug- und im Heckbereich den gleichen Durchmesser hat, lässt sich nicht in dieses Waffenrohr einführen.A modified training floor is shown in FIG. For the same elements as in the embodiment according to Figure 1, the same reference numerals are used. With this The propellant charge 6 located at the rear is shot through a destructible cap or rupture disk 71 covered; the partition with the nozzle is missing. In the bow area is the Diameter of the practice floor reduced, so that a Stop 72 results, which then on a corresponding Stop 73 of the weapon barrel 21 schematically indicated here is applied. The gun barrel in this bow area of the Bullet has a smaller diameter than in rear area of the projectile. Live ammunition released in Bow and stern area has the same diameter do not introduce yourself into this gun barrel.

Die Funktionen beim Abschuss sind die gleichen wie oben beschrieben; der Dorn, der bei der obigen Ausführung in den Kanal 8 eintauchte, ist bei dieser Ausführung nicht nötig. Es können allerdings auch Dorn und Anschlag gemeinsam benutzt werden. Ebenso ist es möglich, nicht ein Waffenrohr für scharfe Munition durch einen Einsatz zu modifizieren, sondern ein eigenes Übungsrohr bereit zu stellen. Falls Blitz-, Rauchund Knallentwicklung nicht simuliert werden, können die erwähnten Überströmkanäle in der Gasdrossel auch fortgelassen werden, sodass der gesamte Gasdruck für das Rücktreiben des Geschosses und das Weiterschalten des Waffenschlosses genutzt wird. The functions at launch are the same as above described; the mandrel, which in the above execution in the Channel 8 immersed is not necessary with this version. It can also use thorn and stop together become. It is also possible not to use a gun barrel for to modify live ammunition through an insert, but to provide your own practice tube. If lightning, smoke and Bang development can not be simulated, the mentioned overflow channels in the gas throttle also omitted so that the total gas pressure for driving back the Bullet and the switching of the weapon lock used becomes.
