Definitions
- the present invention relates to a training cartridge for recoil-free defense weapons, such as the apelooka.
- DE-A-2 059 202 describes such a training cartridge, which is housed in a cartridge case, has a high-weight projectile head and a Deut loading and insulation from cardboard disks or plastic granules.
- 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 angle of attack, generates a projectile swirl.
- a disadvantage of conventional practice cartridges is that they have unsatisfactory flight behavior and sometimes even hit the target in a transverse position, i.e. 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 that affects storage stability (cardboard discs).
- 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 of this on the one hand rotten and at the same time space-saving and storage-stable.
- 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, 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.
- the empennage itself is preferably guided in the cartridge case in a sliding fit, which enables a precise launch that is free of tilting moment until it emerges from the 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.
- the cone itself is preferably also truncated.
- 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.
- 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.
- 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.
- a design has proven to be particularly stable in flight 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 diameter of the projectile head or of the caliber, the mass of the projectile head making up approximately 84 to 94% of the total weight and its length or the length of the fragmentation charge 40-60% of the total length.
- 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.
- a certain opening of the fins between each other is also required for a perfect flow.
- An eight-fold tail has proven particularly useful for conventional rocket propellant ammunition.
- the insulation further consists of iron powder or preferably of pressed or sintered metal, preferably iron powder.
- Metal powder such as preferably iron powder
- Metal 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.
- the metal powders can preferably be entered as compacts 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.
- 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.
- a suitable disc In connection with the formation of the propellant charge from nitroglycerin powder, u. a. low residue combustion with improved firing behavior.
- the propellant charge is fired through an ignition channel, which is arranged in the cartridge case.
- 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.
- 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 clamping seat 12, in which the cartridge case 1 is folded over at right angles at the screwing point between the projectile head 2 and intermediate piece 11 and is clamped by screwing parts 2 and 11 together.
- 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.
- the cartridge case is screwed to the rearward-engaging deuteration case 16.
- the front Deutch 18 is to which the rear Deutch 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 braked suddenly because of their small grain size. Ultimately, iron powder rots relatively quickly.
- the compaction compacts are in the form of perforated disks.
- the propellant charge 15 consists of nitroglycerin powder and is covered on both sides by plastic discs glued with tissue paper.
- the front Deut charge 18 consists of black powder, the rear Deut charge 19 made of nitrocellulose powder. With 22 the ignition channel is designated.
- Fig. 2 shows the floor in plan view and in section with two versions of the stage according to the invention.
- the projectile head 2 can be solid or can be filled with a pulverized charge 3.
- the hollow body 20 can also be made of plastic, e.g. B. Ultramid exist.
- 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.
- the projectile head 2 is screwed to the adjoining tapered intermediate piece 11.
- this is preferably made of metal (aluminum).
- 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.
- 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.
- 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.
- the tracer 22 is located inside the tail boom 14.

Abstract
Description
Die vorliegende Erfindung betrifft eine Übungspatrone für rückstoßfreie Abwehrwaffen, wie z.B. die Panzerfaust. In der DE-A-2 059 202 ist eine derartige Übungspatrone beschrieben, die in einer Patronenhülse untergebracht ist, einen hochgewichtigen Geschoßkopf sowie eine Deutladung und eine Verdämmung aus Pappscheiben oder Kunststoffgranulat besitzt.The present invention relates to a training cartridge for recoil-free defense weapons, such as the bazooka. DE-A-2 059 202 describes such a training cartridge, which is housed in a cartridge case, has a high-weight projectile head and a Deut loading and insulation from cardboard disks or plastic granules.
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.In order to stabilize the flight characteristics of the projectile, it has an assembled, i.e. 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 angle of attack, generates a projectile swirl.
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, i.e. 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 that affects storage stability (cardboard discs).
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 of this 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, 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, transverse hits are not observed with such a projectile 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 preferably guided in the cartridge case 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 Geschoßkopfdurchmessers 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 design has proven to be particularly stable in flight 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 diameter of the projectile head or of the caliber, the mass of the projectile head making up approximately 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, a certain opening of the fins between each other is also required for a perfect flow. An eight-fold tail has proven particularly useful for conventional rocket propellant 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 compacts 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.
