Description

Die vorliegende Erfindung betrifft eine Übungspatrone für rückstoßfreie Abwehrwaffen, wie z.B. die Panzer­faust. Sie geht dabei von einem Stand der Technik aus, wie er z.B. in der DE-AS 20 59 202 beschrieben ist. Danach besteht eine derartige Übungspatrone aus einer Treibladungshülse zur Unterbringung einer Treibladung und eines Unterkalibergeschosses, das aus einem in einem Scheingeschoß untergebrachten Unterkaliberlauf ver­schossen wird, wobei das Scheingeschoß mit seinem, den Unterkaliberlauf koaxial umgebenden Hohlschaft in die Laufmündung eingeführt wird und mittels einer das Ausstoßen des Scheingeschosses bewirkenden sowie den Abschußknall simulierenden Ausstoßladung versehen ist, die in einer an den Boden der Treibladungshülse an­schließenden, im Lauf geführten Ausstoßladungshülse untergebracht ist und deren Pulverladung seitlich durch die Hülsenwand im Bereich einer ringnutförmigen, den Zündstrahl durchlassenden Querschnittsschwächung gezündet wird und die Zündung durch einen axialen Kanal in einem Zwischenboden auf die Treibladung überträgt.The present invention relates to a training cartridge for recoil-free defense weapons, such as the bazooka. It is based on a state of the art, as described for example in DE-AS 20 59 202. According to this, such a practice cartridge consists of a propellant charge sleeve for accommodating a propellant charge and a sub-caliber projectile which is fired from a sub-caliber barrel accommodated in a dummy storey, the dummy projectile being inserted into the barrel muzzle with its hollow shaft coaxially surrounding the sub-caliber barrel and by means of an ejection of the dummy projectile effecting and the firing bang simulating ejection charge is provided, which is accommodated in an ejection charge sleeve connected to the bottom of the propellant charge sleeve and guided in the barrel and the powder charge of which is ignited laterally through the sleeve wall in the region of an annular groove-shaped cross-sectional weakening which allows the ignition beam to pass through and the ignition through an axial channel transfers to the propellant charge in an intermediate floor.

Zur Stabilisierung der Flugeigenschaften des Geschosses weist dieses ein in zusammengebauten, d. h. in der Patronen­hülse befindlichem Zustand, in gleicher Drehrichtung gefal­tetes Leitwerk aus Metallblech auf. Nach dem Abschuß und dem Verlassen der Patronenhülse entfaltet sich dieses Leitwerk um die Flugbahn zu stabilisieren bzw. bei Anbringung unter einem bestimmten Einstellwinkel erzeugt es einen Geschoß­drall.To stabilize the flight characteristics of the projectile, this has an assembled, ie. H. state in the cartridge case, tail unit made of sheet metal folded in the same direction of rotation. After firing and leaving the cartridge case, this tail unit unfolds in order to stabilize the trajectory or, when attached at a certain setting angle, generates a projectile swirl.

Zum Massenausgleich, d. h. zur Vermeidung eine Rückstoßes, weisen derartige Patronen hinter ihrer Deutladung eine Ver­dämmung aus Pappscheiben (DE-AS 20 59 202) oder aus Kunst­stoffgranulat auf.For mass balance, d. H. To avoid recoil, such cartridges have an insulation made of cardboard disks (DE-AS 20 59 202) or plastic granules behind their Deut loading.

Letztlich ist noch aus der DE-OS 33 18 201 bekannt, den Ge­schoßkopf mit Metallpulver oder Keramikpulver zu füllen, um diesen beim Auftreffen auf die Übungsscheibe zu zerlegen und dem Geschoß schlagartig kinetische Energie zu entziehen.Ultimately, it is also known from DE-OS 33 18 201 to fill the projectile head with metal powder or ceramic powder in order to disassemble it when it hits the training disc and to suddenly withdraw kinetic energy from the projectile.

Nachteilig ist bei herkömmlichen Übungspatronen, daß sie ein nicht befriedigendes Flugverhalten aufweisen und bisweilen sogar in Querlage auf die Zielscheibe auftreffen, d. h. tru­deln und daß nach dem Übungsschießen nicht verrottendes Ma­terial aus der Verdämmung auf dem Boden verbleibt (Kunst­stoff) oder, daß durch diese Feuchtigkeit bei der Montage eingeschleppt wird, die die Lagerstabilität beeinträchtigt (Pappscheiben).A disadvantage of conventional practice cartridges is that they have unsatisfactory flight behavior and sometimes even hit the target in a transverse position, ie. H. spin and that after the practice shooting non-rotting material from the dam remains on the floor (plastic) or that moisture is introduced during assembly, which affects storage stability (cardboard disks).

Die vorliegende Erfindung hat sich daher die Aufgabe ge­stellt, eine kostengünstige Übungspatrone mit verbesserten Flugeigenschaften des Geschosses und somit erhöhter Treffer­genauigkeit zu schaffen und weiterhin durch Verwendung eines bestimmten Materials für die Verdämmung dieses einerseits verrottbar und gleichzeitig platzsparend und lagerstabil zu gestalten.The present invention has therefore set itself the task of creating a cost-effective practice cartridge with improved flight characteristics of the projectile and thus increased hit accuracy and further by using a certain material for the insulation on the one hand rotten and at the same time space-saving and storage-stable.

Die Lösung dieser Aufgabe gelingt mit einer Übungspatrone für rückstoßfreie Abwehrwaffen bestehend aus in einer Patro­nenhülse untergebrachtem hochgewichtigen Geschoßkopf vor­zugsweise mit Zerlegerkern und einem Leitwerk sowie Deut­ladung und Verdämmung dadurch gekennzeichnet, daß der Ge­schoßkopf stirnseitig eine Stufe aufweist und daß zwischen Geschoßkopf und Leitwerk ein sich zum Leitwerk hin verjün­gendes Zwischenstück angeordnet ist, wobei Zwischenstück und Leitwerk aus Leichtmaterial wie Kunststoff oder vorzugsweise Aluminium gefertigt sind und daß das Leitwerk kalibergleich ausgeführt ist.The solution to this problem is achieved with a practice cartridge for recoil-free defense weapons consisting of a high-weight projectile head housed in a cartridge case, preferably with a disassembly core and a tail unit, as well as loading and unloading, characterized in that the projectile head has a step on the end face and that between the projectile head and the tail unit there is a tail unit Tapered intermediate piece is arranged, wherein the intermediate piece and tail unit are made of light material such as plastic or preferably aluminum and that the tail unit is of the same caliber.

Überraschenderweise werden quer einschlagende Treffer mit einem derartigen Geschoß nicht beobachtet und die Treffer­genauigkeit ist erheblich gesteigert, obwohl der Durchmesser des Leitwerks nunmehr lediglich maximal genauso groß sein kann wie der Durchmesser des Geschoßkopfes bzw. der Innen­durchmesser der Patronenhülse. Dies bedeutet, daß die erfin­dungsgemäße Merkmalskombination aus Schwerpunktlage und aerodynamischer Besonderheit eine bessere Anströmung des Leitwerkes und eine Vermeidung der Taumelbewegung des Ge­schosses bewirken.Surprisingly, hits with such a projectile are not observed transversely and the accuracy of the hit is considerably increased, although the diameter of the tail unit can now only be as large as the diameter of the projectile head or the inner diameter of the cartridge case. This means that the combination of features according to the invention consisting of the center of gravity and the aerodynamic peculiarity result in a better flow towards the tail unit and avoid the tumbling movement of the projectile.

Das Leitwerk selbst ist in der Patronenhülse vorzugsweise im Gleitsitz geführt, wodurch ein präziser und bis zum Austritt aus der Hülse kippmomentfreier Abschuß möglich ist.The empennage itself is guided in the cartridge case, preferably in a sliding fit, which enables a precise launch that is free of tilting moment until it emerges from the case.

Die vordere Stufe des Geschoßkopfes kann im einfachsten Falle eine ebene Fläche sein, die jedoch einen relativ hohen Stirnwiderstand bedingt. Es wird daher weiterhin vorge­schlagen, auf dieser Stufe zentral einen Kegel anzuordnen, dessen Fußdurchmesser geringer als der des Geschoßkopfes ist, so daß außen um diesen ein randseitiger Ring entsteht.In the simplest case, the front step of the projectile head can be a flat surface, but this requires a relatively high face resistance. It is therefore still proposed to arrange a cone centrally at this level, whose foot diameter is smaller than that of the projectile head, so that an outer ring is formed around it.

Der Kegel selbst ist vorzugsweise ebenfalls abgestumpft.The cone itself is preferably also truncated.

Das Leitwerk besteht ebenso wie das Zwischenstück in beson­ders vorteilhafter, d. h. kostengünstiger Weise aus strang­gepreßtem Aluminium oder ähnlichem duktilem Material oder aber auch aus Kunststoff.The tail unit, like the intermediate piece, is particularly advantageous, i.e. H. inexpensively made of extruded aluminum or similar ductile material or of plastic.

Das Geschoß ist vorzugsweise dreiteilig aufgebaut und besteht aus dem Geschoßkopf der massiv oder hohl und mit Metall­pulver oder Keramikpulver gefüllt sein kann und einem sich zum Leitwerk hin verjüngenden Zwischenstück, wobei alle Teile miteinander verschraubt sind.The projectile is preferably constructed in three parts and consists of the projectile head which can be solid or hollow and filled with metal powder or ceramic powder and an intermediate piece which tapers towards the tail unit, all parts being screwed together.

Das Leitwerk besitzt einen nach rückwärts offenen Napf zur Aufnahme der Leuchtspur. Bei Ausführung des Leitwerks als Kunststoffteil kann es daher erforderlich sein, diese in einem Metalleinsatz unterzubringen.The tail unit has a backward-open bowl to accommodate the tracer. If the tail unit is designed as a plastic part, it may be necessary to place it in a metal insert.

Mit der vorliegenden Anordnung ist eine genaue ballistische Abstimmung des Schwerpunktes auf die Raummaße möglich. Als besonders flugstabil und treffergenau hat sich eine Kon­struktion erwiesen, bei der die Breite der Ringfläche etwa das 0,1 bis 0,2-fache und die Länge des Geschosses etwa das 3,8 bis 5,2-fache des Geschoß­ kopfdurchmessers bzw. des Kalibers beträgt, wobei die Masse des Geschoßkopfes etwa 84 bis 94 % des Gesamt­gewichtes und dessen Länge bzw. die Länge der Zerleger­ladung 40-60 % der Gesamtlänge ausmacht.With the present arrangement, an exact ballistic adjustment of the center of gravity to the room dimensions is possible. A construction has proven to be particularly flight-stable and accurate, in which the width of the ring surface is approximately 0.1 to 0.2 times the length of the projectile and 3.8 to 5.2 times the projectile Head diameter or caliber, the mass of the projectile head makes up about 84 to 94% of the total weight and its length or the length of the fragmentation charge 40-60% of the total length.

Die Leitwerksflossen weisen vorzugsweise äußere achs­parallele Kanten auf, die an der Innenwandung der Patrone anliegen und das Geschoß beim Austritt aus dieser führen. Mit der Zahl der Flossen steigt dabei auch die Führungs­genauigkeit. Andererseits ist aber auch zur einwand­freien Anströmung eine gewisse Öffnung der Flossen zwischeneinander erforderlich. Für herkömmliche Panzerfaustübungsmunition hat sich ein achtzähliges Leitwerk besonders bewährt.The tail fins preferably have outer, axially parallel edges, which abut the inner wall of the cartridge and guide the projectile as it exits. The number of fins increases the accuracy of guidance. On the other hand, however, a certain opening of the fins between one another is also necessary for a perfect flow. An eight-tail empennage has proven particularly useful for conventional bazooka practice ammunition.

Erfindungsgemäß besteht weiterhin die Verdämmung aus Eisenpulver bzw. vorzugsweise aus gepreßtem oder gesintertem Metall- vorzugsweise Eisenpulver.According to the invention, the insulation further consists of iron powder or preferably of pressed or sintered metal, preferably iron powder.

Metallpulver, wie vorzugsweise Eisenpulver, weist gegen­über Kunststoffgranulat oder Pappscheiben wesentliche Vorteile auf. Zum einen ist wegen des höheren spezifischen Gewichtes eine Verkleinerung der Baumaße möglich. Zum anderen verrottet feines Eisenpulver gut.Metal powder, such as preferably iron powder, has significant advantages over plastic granules or cardboard disks. Firstly, because of the higher specific weight, it is possible to reduce the dimensions. On the other hand, fine iron powder rots well.

Wegen der höheren spezifische Wärme des Metalls gegen­über Kunststoff oder Pappmaterial ist dieses jedoch in der Lage, die gegen die Schußrichtung ausgestoßene Flamme weit besser zu kühlen, so daß auch die Ver­letzungsgefahr herabgesetzt ist.Because of the higher specific heat of the metal compared to plastic or cardboard material, however, it is able to cool the flame expelled against the direction of the shot far better, so that the risk of injury is also reduced.

Die Metallpulver können vorzugsweise als Preßkörper oder Sintermaterialien eingegeben werden, diese haben zum einen eine sehr geringe Oberfläche und bringen somit wenig adsorptives Wasser ein, sie können zusätzlich mit einem Lacküberzug versehen sein und so die Lager­stabilität beträchtlich erhöhen.The metal powders can preferably be entered as pressed bodies or sintered materials, on the one hand they have a very small surface area and thus introduce little adsorptive water, they can additionally be provided with a lacquer coating and thus considerably increase the storage stability.

Die Preßkörper müssen jedoch Austritt aus der Deut­ladungspatrone vollständig in ihre Pulverteilchen zer­legt werden. Es hat sich durch Versuche herausgestellt, daß dies im Falle von Preßkörpern besonders zuverlässig geschieht, die die Form von Lochscheiben aufweisen.However, the compacts must be completely disassembled into their powder particles as they emerge from the Deutladungs cartridge. It has been found through tests that this takes place particularly reliably in the case of pressed bodies which have the shape of perforated disks.

Eine weitere Verbesserung der Übungspatrone besteht in der Auftrennung der Deutladung in eine vordere aus Schwarzpulver und eine hintere aus Nitrocellulosepulver, die beide voneinander durch eine geeignete Scheibe ge­trennt sind. In Verbindung mit der Ausbildung der Treib­ladung aus Nitroglycerinpulver entsteht u. a. eine rück­standsarme Verbrennung bei gleichzeitig verbessertem Abschußverhalten.Another improvement of the practice cartridge is the separation of the Deut charge into a front one made of black powder and a rear one made of nitrocellulose powder, both of which are separated from each other by a suitable disc. In connection with the formation of the propellant charge from nitroglycerin powder, u. a. low residue combustion with improved firing behavior.

Die Treibladung wird dabei durch einen Durchzündkanal angefeuert, der in der Patronenhülse angeordnet ist.The propellant charge is fired through an ignition channel, which is arranged in the cartridge case.

Anhand der beiliegenden Figuren wird die vorliegende Erfindung näher erläutert.

The present invention is explained in more detail with reference to the accompanying figures.
  • Fig. 1 shows the entire structure of the practice cartridge.
  • Fig. 2 shows the floor.

Fig. 1 zeigt die Übungspatrone mit dem Geschoß. Dieses besteht aus dem Geschoßkopf 2, dem sich verjüngenden Zwischenstück 11 und dem daran anschließenden Leitwerk 4.Fig. 1 shows the practice cartridge with the projectile. This consists of the projectile head 2, the tapering intermediate piece 11 and the tail assembly 4 connected to it.

Das Geschoß ist in der Patronenhülse 1 gelagert und durch die Leitwerkskanten 8 in der Hülseninnenwandung geführt. Die Hülse hält das Geschoß im Klemmsitz 12, in dem die Patronenhülse 1 an der Schraubstelle zwischen dem Geschoßkopf 2 und Zwischenstück 11 rechtwinklig um­gelegt und durch Verschrauben von Teil 2 und 11 verklemmt wird.The projectile is mounted in the cartridge case 1 and guided through the tail edges 8 in the inner wall of the case. The sleeve holds the projectile in the clamp seat 12, in which the cartridge case 1 is folded over at right angles at the screwing point between the projectile head 2 and the intermediate piece 11 and is clamped by screwing parts 2 and 11 together.

Das Leitwerk stößt auf eine Liderungskappe 13, die eine zentrale Bohrung zur Zündung der Leuchtspur im Inneren des Leitwerkträgers 14 aufweist. Unterhalb der Liderungskappe befindet sich die Treibladung 15 in einer entsprechenden Ausnehmung der Patronenhülse 1.The tail unit encounters a eyelid cap 13 which has a central bore for igniting the tracer in the interior of the tail unit carrier 14. The propellant charge 15 is located below the eyelid cap in a corresponding recess in the cartridge case 1.

Die Patronenhülse 1 ist mit der nach rückwärts an­schließenden Deutladungshülse 16 verschraubt.The cartridge case 1 is screwed to the Deutladungshülse 16 connecting to the rear.

In der Deutladungshülse 16, der als Ringnut ausge­bildeten Zündkerbe 17 zugeordnet, befindet sich die vordere Deutladung 18, an die die hintere Deutladung 19 und die Verdämmung 5 anschließen. Diese Verdämmung besteht aus durch Sintern oder Pressen verdichtetem Eisenpulver in Form von Scheiben, die beim Ausstoßen pulveri­siert werden und durch ihre große Oberfläche und ihre spezifische Wärme die austretende Flamme kühlen und andererseits wegen ihrer geringen Korngröße auch schlag­artig abgebremst werden. Letztlich verrottet Eisenpulver relativ schnell.In the Deutladungshülse 16, which is designed as an annular groove spark notch 17, the front Deutchar 18 is to which the rear Deutchar 19 and the dam 5 connect. This insulation consists of iron powder compacted by sintering or pressing in the form of disks, which are pulverized when ejected and cool the escaping flame due to their large surface area and their specific heat and, on the other hand, are abruptly braked due to their small grain size. Ultimately, iron powder rots relatively quickly.

Die Preßlinge der Verdämmung 5 weisen die Form von Lochscheiben auf.The compacts of the dam 5 have the shape of perforated disks.

Die Treibladung 15 besteht aus Nitroglycerinpulver und ist beidseitig von mit Seidenpapier beklebten Kunststoffscheiben abgedeckt. Die vordere Deutladung 18 aus Nitrocellulosepulver. Mit 21 ist der Zündkanal bezeichnet.The propellant charge 15 consists of nitroglycerin powder and is covered on both sides by plastic discs glued with tissue paper.

Fig. 2 zeigt das Geschoß in Draufsicht und im Schnitt mit zwei Versionen der erfindungsgemäßen Stufe.Fig. 2 shows the floor in plan view and in section with two versions of the stage according to the invention.

Der Geschoßkopf 2 kann massiv ausgebildet oder mit einer pulverförmigen Zerlegerladung 3 gefüllt sein. In letzterem Falle kann der Hohlkörper 20 auch aus Kunststoff, z. B. Ultramid, bestehen. An die Stufe 6 schließt der abge­stumpfte Kegel 9 an, wodurch eine Ringfläche 10 entsteht, deren Breite z. B. etwa ein Drittel der gesamten pro­jizierten Fläche betragen kann, dabei beträgt der Außen­durchmesser z. B. 18 mm und der Durchmesser des Kegel­fußes 13 mm.The projectile head 2 can be solid or can be filled with a pulverized charge 3. In the latter case, the hollow body 20 can also be made of plastic, e.g. B. Ultramid exist. At the stage 6, the truncated cone 9 connects, creating an annular surface 10, the width of z. B. can be about a third of the total projected area, the outer diameter is z. B. 18 mm and the diameter of the conical foot 13 mm.

Der Geschoßkopf 2 ist mit dem sich anschließenden sich verjüngenden Zwischenstück 11 verschraubt. Dieses besteht aus Stabilitätsgründen vorzugsweise aus Metall (Alu­minium).The projectile head 2 is screwed to the adjoining tapered intermediate piece 11. For reasons of stability, this is preferably made of metal (aluminum).

Mit dem Zwischenstück 11 wiederum ist der Leitwerks­träger 14 verschraubt. Dieser ist zylinderförmig aus­gebildet und trägt die Leitwerksflossen 4 mit den Führungskanten 8.The tail boom 14 is in turn screwed to the intermediate piece 11. This is cylindrical and carries the tail fins 4 with the guide edges 8.

Diese Art der Raumform ermöglicht eine einfache Her­stellung des gesamten Leitwerks aus z. B. strang­gepreßtem Aluminium oder einer Fertigung als Guß- oder Spritzgußteil, auch aus Kunststoff.This type of room shape enables easy manufacture of the entire tail unit from e.g. B. extruded aluminum or a production as a cast or injection molded part, also made of plastic.

Der Geschoßkopf 2 kann in einfacher Weise auch voll­kommen flach mit einer Zylinderfläche 21 ausgebildet sein, wobei die Flugstabilität erhalten bleibt, der Stirnwiderstand jedoch ansteigt.The projectile head 2 can also be designed in a simple manner to be completely flat with a cylindrical surface 21, the flight stability being retained, but the face resistance increasing.

Im Inneren des Leitwerkträgers 14 befindet sich die Leuchtspur 22.The tracer 22 is located inside the tail boom 14.
