Abstract

There is proposed an ejector device (6) for grenade projector or mortar projectiles (1), which permits simulation of mortar firing even in halls or very limited areas. It is known that blank cartridges (17) for rifles, pistols or bolt firing devices have only a slight degree of scatter in terms of gas pressure. Therefore the ejection speed of a piston (13) which is inserted into the ejector device (6) and which is driven by the powder propellent gases of the blank cartridge (17) is always the same. In that way it is always possible to achieve the same firing ranges of only a few meters.

Description

Die Erfindung betrifft eine Auswurfeinrichtung für Granatwerfer- bzw. Mörsergeschosse zur Simulation eines Schusses, mit einer in einer separaten Kammer im Geschoßkörper eingesetzten Treibladung.The invention relates to an ejection device for grenade launcher or mortar projectiles for simulating a shot, with a propellant charge used in a separate chamber in the projectile body.

Aus der den nächsten Stand der Technik bildenden DE 30 33 061 A1 ist ein Granatwerfer-Übungsgeschoß bekannt, welches mit einem Kopf- und einem Schwanzteil sowie mit einer Treibladung im Schwanzteil und mit einer vor dieser angeordneten, raucherzeugenden Signalladung versehen ist. Die Treibladung bei diesem Übungsgeschoß befindet sich in einer separaten, in das hintere Ende des Schwanzteiles eingesteckten Kammer. Ziel bei diesem Übungsgeschoß ist es, seine Handhabung weitgehend mit einem entsprechenden scharfen Geschoß übereinstimmen zu lassen und trotz fehlender Sprengwirkung beim Aufschlag eine gute Einschlagsmarkierung im Zielgebiet zu ermöglichen. Die Markierungsladung ist deshalb von der Treibladung getrennt im Schwanzrohr des Übungsgeschosses eingefüllt. Die Simulation eines Schusses aus einem Mörser auf kleinstem Raum ist mit diesem Übungsgeschoß nicht möglich.From DE 30 33 061 A1, which forms the closest prior art, a grenade launcher training projectile is known, which is provided with a head part and a tail part as well as with a propellant charge in the tail part and with a smoke-generating signal charge arranged in front of it. The propellant charge on this training projectile is located in a separate chamber which is inserted into the rear end of the tail part. The aim of this training projectile is to have its handling largely correspond to a corresponding sharp projectile and to enable good impact marking in the target area despite the lack of explosive effect on impact. The marker charge is therefore filled separately from the propellant charge in the tail tube of the practice floor. The simulation of a shot from a mortar in the smallest space is not possible with this practice floor.

Aus dem DE 84 24 969 U1 ist ein großkalibriges Übungsgeschoß und ein Simulatorsystem für dieses Übungsgeschoß offenbart worden. Dabei wird insbesondere die Nachbildung von tatsächlichen Geschossen angestrebt, die im wesentlichen mit der vorschriftsmäßigen Ausrüstung übereinstimmt, so daß tatsächliche Schießbedingungen nachgeahmt werden können.DE 84 24 969 U1 has disclosed a large-caliber training floor and a simulator system for this training floor. In particular, the aim is to reproduce actual projectiles that essentially correspond to the correct equipment, so that actual shooting conditions can be imitated.

Um dieses Übungsgeschoß über variable Reichweiten abschießen zu können und die Übungsgranate unter Nachahmung der tatsächlichen Schießbedingungen schnell in einer vorschriftsmäßigen Waffe zu Ausbildungszwecken laden zu können, besitzt der Kopfteil dieses Übungsgeschosses einen Innengasdurchlaß mit Öffnungen für den Eintritt der Treibgase. Für den Austritt der Treibgase sind weitere Bohrungen vorgesehen, wodurch beim Abschuß dieses Übungsgeschosses bewirkt wird, daß die entstehenden Treibgase durch die Einlaßöffnungen vorwärts entlang dem Innendurchlaß und aus den Austrittsöffnungen wieder herausgeleitet werden. Durch Stöpsel sind die Eintrittsöffnungen verschließbar, wodurch zwischen den Eintrittsöffnungen und den Austrittsöffnungen unterschiedliche Querschnittsflächen entstehen. Durch das Öffnen bzw. das Verschließen von solchen Eintrittsöffnungen kann der Schußbereich einer solchen Übungsgranate von 250 Metern bis zu 600 Metern variiert werden. Damit ist auch dieses Übungsgeschoß nicht für die Schußsimulation auf kleinstem Raum und in Montagehallen geeignet.In order to be able to fire this practice projectile over variable ranges and to be able to load the practice grenade quickly in a prescribed weapon for training purposes, imitating the actual shooting conditions, the head section of this practice projectile has an internal gas passage with openings for the entry of the propellant gases. Further holes are provided for the exit of the propellant gases, whereby when this training projectile is fired, the resultant propellant gases are directed forward through the inlet openings along the inner passage and out of the outlet openings. The inlet openings can be closed by plugs, as a result of which different cross-sectional areas arise between the inlet openings and the outlet openings. By opening or closing such entry openings, the shooting range of such a practice grenade can be varied from 250 meters to 600 meters. So this practice floor is also not suitable for shooting simulation in the smallest space and in assembly halls.

Es ist Aufgabe der Erfindung, eine Auswurfeinrichtung für Granatwerfer- bzw. Mörsergeschosse zur Simulation eines Schusses zu schaffen, die mit einfachen Mitteln das Handling eines Mörsers oder eines Granatwerfers in einer Halle oder auf einem begrenzten Übungsplatz ermöglicht und sämtliche Bewegungsabläufe wie bei einem scharfen Geschoß beibehält.It is an object of the invention to provide an ejection device for grenade launcher or mortar projectiles for simulating a shot, which enables the handling of a mortar or a grenade launcher in a hall or on a limited exercise area with simple means and maintains all movement sequences as with a sharp projectile .

Erfindungsgemäß ist diese Aufgabe durch die Merkmale des Patentanspruches 1 gelöst. Ausgestaltungen und Weiterbildungen dieser im Patentanspruch 1 aufgezeigten Lösung sind den Unteransprüchen 2 bis 7 zu entnehmen.According to the invention, this object is achieved by the features of patent claim 1. Refinements and developments of this solution indicated in claim 1 can be found in the subclaims 2 to 7.

Bei den bekannten großkalibrigen Übungsgeschossen für Mörser und Granatwerfer nach dem Stand der Technik gibt es derzeit keine Möglichkeit, in einer Montagehalle oder bei nur beschränkt zur Verfügung stehendem Raum die Beladung eines Mörsers zu simulieren. Selbst spezielle Ladungen für Übungsgeschosse benötigen einen relativ großen und abgesicherten Platz. Bedingt durch den relativ großen Anfangsbrennraum und dem durch den Luftspalt zwischen dem Abschußrohr und dem Geschoß großen Gasschlupf ist es oft schwierig, eine entsprechende Ladung zu laborieren, die das großkalibrige Übungsgeschoß zuverlässig nur wenige Meter weit schleudert. Hier geht die Erfindung nun einen völlig neuen Weg. Es ist bekannt, daß Platzpatronen für Gewehre oder Pistolen oder für Bolzenschußgeräte nur eine sehr geringe Streuung im Gasdruck aufweisen. Daher ist die Ausstoßgeschwindigkeit des erfindungsgemäß eingesetzten Kolbens, der von den Pulvergasen der eingesetzten Platzpatrone getrieben wird, immer gleich. Dadurch lassen sich immer gleiche Wurfweiten erzielen. Am Ende des Beschleunigungsweges des Kolbens sind ferner Ablaßöffnungen angebracht, so daß bei der Demontage der Auswurfeinrichtung aus einer abgeschossenen Mörserpatrone kein Druck auf dem Kolben vorhanden ist.In the known large-caliber practice projectiles for mortars and grenade launchers according to the prior art, there is currently no possibility of simulating the loading of a mortar in an assembly hall or in the case of only a limited amount of space. Even special loads for training projectiles require a relatively large and secure space. Due to the relatively large initial combustion chamber and the large amount of gas slippage due to the air gap between the launch tube and the projectile, it is often difficult to laboratoryize a corresponding charge that reliably throws the large-caliber practice projectile only a few meters away. Here, the invention now goes a completely new way. It is known that blank cartridges for rifles or pistols or for nail guns have only a very small variation in gas pressure. Therefore, the ejection speed of the piston used according to the invention, which is driven by the powder gases of the blank cartridge used, is always the same. This means that the same throw distances can always be achieved. At the end of the acceleration path of the piston, drain openings are also provided, so that there is no pressure on the piston when the ejection device is removed from a mortar cartridge that has been fired.

Durch die Fallenergie des Mörsergeschosses beim Aufschlagen auf das Bodenstück im Mörser-Waffenrohr wird der Kolben gegen den feststehenden Schlagbolzen in der Auswurfeinrichtung geschlagen, wodurch die im Kolben gelagerte Platzpatrone gezündet wird. Die dabei freigesetzten Pulvergase treiben den Kolben mit hoher Geschwindigkeit gegen seinen ringförmigen Anschlag im Hohlzylinder. Der Kolben stößt sich vom Bodenstück des Mörser-Waffenrohres ab und schleudert damit das Übungsgeschoß nur wenige Meter aus dem Rohr heraus.Due to the falling energy of the mortar projectile when it strikes the base in the mortar weapon barrel, the piston is struck against the fixed firing pin in the ejection device, whereby the blank cartridge stored in the piston is ignited. The powder gases released thereby drive the piston at high speed against its annular stop in the hollow cylinder. The piston pushes off the base of the mortar weapon barrel and thus throws the practice projectile out of the barrel only a few meters.

Das Granatwerfer- bzw. Mörsergeschoß 1 besteht aus einem Kopfteil 2 und einem Schwanzteil 3 mit Stabilisierungsflügeln 4. Im Schwanzteil 3 ist von der rückwärtigen Seite eine Sackbohrung 5 eingebracht, welche die Auswurfeinrichtung 6 aufnimmt. Die Auswurfeinrichtung 6 für das Mörsergeschoß 1 zur Simulation eines Schusses besteht aus einem Hohlzylinder 7, der mittels eines Gewindes 8 in den Schwanzteil 3 bis gegen einen Anschlag 9 eingeschraubt ist. An seiner dem Kopfteil 2 zugewandten Stirnseite 10 ist der Hohlzylinder 7 durch ein Bodenstück 11 mit einem zentral eingesetzten Schlagbolzen 12 verschlossen. In einem axialen Abstand zum Bodenstück 11 befindet sich in dem Hohlzylinder 7 ein Kolben 13 mit einer von der dem Bodenstück 11 zugewandten Stirnseite 14 eingebrachten Sackbohrung 15. Diese Sackbohrung befindet sich auf der Geschoßkörper-Längsachse 16. In die Sackbohrung 15 ist eine Platzpatrone 17 eingesetzt.The grenade launcher or mortar projectile 1 consists of a head part 2 and a tail part 3 with stabilizing wings 4. In the tail part 3, a blind bore 5 is made from the rear side, which receives the ejection device 6. The ejection device 6 for the mortar projectile 1 for simulating a shot consists of a hollow cylinder 7 which is screwed into the tail part 3 against a stop 9 by means of a thread 8. On its end face 10 facing the head part 2, the hollow cylinder 7 is closed by a base piece 11 with a centrally inserted firing pin 12. At an axial distance from the base piece 11 there is a piston 13 in the hollow cylinder 7 with a blind bore 15 introduced from the end face 14 facing the base piece 11. This blind bore is located on the longitudinal axis 16 of the projectile body. A blank cartridge 17 is inserted into the blind bore 15 .

Das dem Bodenstück 11 zugewandte hintere Ende des Kolbens 13 weist einen erweiterten Durchmesser mit einer axialen Ringfläche 18 auf.The rear end of the piston 13 facing the base piece 11 has an enlarged diameter with an axial annular surface 18.

An dem zum Bodenstück 11 abgewandten Ende ist der Kolben 13 mit einer radialen Sackbohrung 19 versehen. In diese Sackbohrung 19 ist ein Rastbolzen 20 eingesetzt, dessen Bodenfläche 21 eine Öffnung 22 besitzt, in die eine Feder 23 eingreift, welche sich am Boden 24 der Sackbohrung 19 abstützt. Kopfseitig greift der Rastbolzen 20 in eine entsprechende Rastnute oder Rastkerbe 25 in der Innenwand 26 des Hohlzylinders 7 ein.At the end facing away from the base piece 11, the piston 13 is provided with a radial blind bore 19. In this blind bore 19, a locking pin 20 is inserted, the bottom surface 21 of which has an opening 22 into which a spring 23 engages, which is supported on the bottom 24 of the blind bore 19. On the head side, the locking pin 20 engages in a corresponding locking groove or notch 25 in the inner wall 26 of the hollow cylinder 7.

Eine im wesentlichen parallel zur Geschoßlängsachse 16 verlaufende Querbohrung 27 im Rastbolzen 20 nimmt einen Sicherungsstift 28 auf, der sich in einer entsprechenden Bohrung 29 im Kolben 13 abstützt. An dem Sicherungsstift 28 befindet sich zum hinteren Ende der Auswurfeinrichtung 6 ein Zugring 30.A substantially parallel to the longitudinal axis 16 of the cross bore 27 in the locking pin 20 receives a locking pin 28 which is supported in a corresponding bore 29 in the piston 13. A pull ring 30 is located on the locking pin 28 toward the rear end of the ejection device 6.

Die axiale Bewegung des Rastbolzens 20 in der Sackbohrung 19 ist durch einen Stift 31 begrenzt, der fest im Bolzen 13 eingesetzt ist und in eine Randausnehmung 32 des Rastbolzens 20 eingreift.The axial movement of the locking pin 20 in the blind bore 19 is limited by a pin 31 which is firmly inserted in the pin 13 and engages in an edge recess 32 of the locking pin 20.

Der Hohlzylinder 7 besitzt in seinem vorderen Bereich Gasablaßöffnungen 33, die sich am Ende des Beschleunigungsweges des Kolbens 13 bei einer Bewegung in Richtung des Pfeiles 34 befinden. Aufgrund dieser Gasablaßöffnungen 33 ist der Kolben 13 bei der Demontage der Auswurfeinrichtung 6 aus dem Mörsergeschoß 1 ohne Druck.The hollow cylinder 7 has gas discharge openings 33 in its front region, which are located at the end of the acceleration path of the piston 13 during a movement in the direction of the arrow 34. Because of these gas discharge openings 33, the piston 13 is without pressure when the ejection device 6 is removed from the mortar projectile 1.

Der Hohlzylinder 7 ist im Bereich des Geschoßendes mit einem verringerten Durchmesser versehen, wodurch sich eine axiale Ringfläche 35 am Hohlzylinder 7 bildet, die der Ringfläche 18 des Kolbens gegenübersteht. Diese beiden Ringflächen 18 und 35 bilden einen Endanschlag bei Bewegung des Kolbens 13 innerhalb des Hohlzylinders 7 in Richtung des Pfeiles 34.The hollow cylinder 7 is provided with a reduced diameter in the region of the projectile end, as a result of which an axial annular surface 35 forms on the hollow cylinder 7, which faces the annular surface 18 of the piston. These two ring surfaces 18 and 35 form an end stop when the piston 13 moves within the hollow cylinder 7 in the direction of the arrow 34.

Vor der Sackbohrung 19 ist in dem Kolben 13 eine weitere radiale Sackbohrung 36 vorgesehen.A further radial blind bore 36 is provided in the piston 13 in front of the blind bore 19.

Die Schußsimulation mit dem Mörsergeschoß erfolgt dadurch, daß das Mörsergeschoß 1 in ein hier nicht gezeigtes Waffenrohr eines Mörsers von der Waffenrohrmündung her eingebracht wird. Durch die Fallenergie des Mörsergeschosses 1 beim Aufschlagen auf das Mörserrohrbodenstück wird nun der Kolben 13 gegen den feststehenden Schlagbolzen 12 in dem Bodenstück 11 der Auswurfeinrichtung 6 geschlagen, wodurch die in dem Kolben 13 gelagerte Platzpatrone 17 gezündet wird.The shot simulation with the mortar projectile takes place in that the mortar projectile 1 is inserted into a weapon barrel (not shown here) of a mortar from the weapon barrel mouth. Due to the falling energy of the mortar projectile 1 when it strikes the bottom of the mortar tube, the piston 13 is now struck against the fixed firing pin 12 in the bottom part 11 of the ejection device 6, as a result of which the blank cartridge 17 stored in the piston 13 is ignited.

Die dabei nun freigesetzten Pulvertreibgase treiben den Kolben 13 mit hoher Geschwindigkeit gegen seinen Anschlag 18 und 35 im Hohlzylinder 7. Der Kolben 13 wird demzufolge aus dem hinteren Ende des Geschosses herausgetrieben und stößt sich dabei von dem Bodenstück des Waffenrohres im Mörsers ab und schleudert das Mörsergeschoß 1 zusammen mit der Auswurfeinrichtung 6 aus dem Waffenrohr des Mörsers. Die Reichweite des so herausgeschleuderten Mörsergeschosses 1 beträgt nur wenige Meter nach Verlassen des Waffenrohres, so daß sich diese Einrichtung eignet, auch eine Simulation von Mörsern und Mörsergeschossen in einer Halle oder auf sehr kleinen Plätzen durchzuführen.The now released powder propellant gases drive the piston 13 at high speed against its stop 18 and 35 in the hollow cylinder 7. The piston 13 is consequently driven out of the rear end of the projectile and pushes off the base of the weapon barrel in the mortar and throws the mortar projectile 1 together with the ejection device 6 from the barrel of the mortar. The range of the mortar projectile 1 thrown out in this way is only a few meters after leaving the weapon barrel, so that this device is suitable for carrying out a simulation of mortars and mortar projectiles in a hall or in very small spaces.

Durch den Rastbolzen 20 wird der Kolben 13 in seiner Lager- bzw. Transportstellung gemäß Figur 2 im Zylinder gehalten. Erst nach dem Herausziehen des Sicherungsstiftes 28 über den Ring 30 ist eine Bewegung des Rastbolzens 20 innerhalb der Sackbohrung 19 gegen die Wirkung der Feder 23 möglich. Die bei Zündung der Platzpatrone 17 freiwerdende Energie reicht aus, um bei einer Bewegung des Kolbens 13 in Richtung des Pfeiles 34 den Rastbolzen 20 aus der Rastkerbe 25 bis gegen den Anschlagstift 31 herauszudrücken.The piston 13 is held in its storage or transport position according to FIG. 2 in the cylinder by the locking pin 20. Only after pulling out the locking pin 28 via the ring 30 is it possible to move the locking pin 20 within the blind bore 19 against the action of the spring 23. The energy released when the blank cartridge 17 is ignited is sufficient to push the locking pin 20 out of the locking notch 25 against the stop pin 31 when the piston 13 moves in the direction of the arrow 34.
