Description

Die Erfindung beschäftigt sich mit einem so genannten selbstverzehrendem Geschoss bzw. einer Munition, auch mit einem Übungsgeschoss bzw. einer Übungsmunition, die bis zu einer vordefinierten Wirkentfernung wirkt, andererseits bei Überschreitung dieser Entfernung deutlich schnell die Geschwindigkeit abbaut.The invention deals with a so-called self-consumable projectile or ammunition, also with a practice projectile or practice ammunition, which is effective up to a predefined effective distance, but which, on the other hand, quickly reduces the speed when this distance is exceeded.

Aus der DE 10 2005 030 263 B3 ist ein Sicherheitssystem für tempierbare Munition mit Selbstzerlegung bekannt. Dabei bleibt ein Selbstzerlegungsmechanismus solange aktiv, bis eine Überprüfung der Funktion eines Zünders abgeschlossen ist. Bei negativem Ergebnis erfolgt eine Selbstzerlegung, die somit an den Anfang der Mission gelegt wird. Weitere Selbstzerlegungseinrichtungen sind der DE 100 20 637 C1 , EP 0 169 171 A1 oder der DE 43 35 938 C2 entnehmbar.From the DE 10 2005 030 263 B3 is a safety system for temporable ammunition with self-disassembly known. A self-destruct mechanism remains active until the function of a detonator has been checked. If the result is negative, self-disassembly takes place, which is thus placed at the beginning of the mission. Other self-decomposition facilities are the DE 100 20 637 C1 , EP 0 169 171 A1 or the DE 43 35 938 C2 removable.

Es sind zudem Gefechtsmunitionen bekannt, bei denen eine im Geschossheck integrierte Leuchtspur kurz vor dem Ende ihrer Brenndauer genutzt wird, die im Geschoss integrierte Sprengladung zu zünden. Dadurch wird verhindert, dass Blindgänger im Kampffeld herumliegen, wenn die Gefechtsmunition das Ziel nicht getroffen hat. Nachteilig ist, dass die notwendige Zuverlässigkeit der Selbstvernichtung nicht immer gewährleistet ist.Combat munitions are also known in which a tracer integrated in the rear of the projectile is used shortly before the end of its burn time to ignite the explosive charge integrated in the projectile. This prevents duds from lying around in the battlefield when the battle ammunition hasn't hit the target. The disadvantage is that the necessary reliability of self-destruction is not always guaranteed.

Konventionelle Geschosse verfügen entsprechend ihrer Mündungsgeschwindigkeit und ihrem Geschossgewicht über eine teilweise hohe Mündungsenergie. Diese wird häufig jedoch ausschließlich über den Luftwiderstand während des Fluges abgebaut. Daraus resultiert abhängig vom Abschusswinkel eine große Schussweite. Diese liegt bei Kalibern im Handwaffenbereich bei einer Flugweite bis zu 2000 m. Die Wirkentfernung insbesondere im Kaliber 9x19 mm sollte aber nur im Bereich bis zu 200 m liegen. Selbst in diesen Entfernungen besitzen derartige Geschosse noch ausreichende Restenergie, um ernsthafte Verletzungen etc. hervorzurufen. Derartige Geschosse weisen keine Selbstzerlegungsmechanismen auf.Depending on their muzzle velocity and bullet weight, conventional bullets sometimes have high muzzle energy. However, this is often reduced exclusively by air resistance during flight. Depending on the firing angle, this results in a large firing range. This is for calibers in the handgun range with a flight range of up to 2000 m. The effective distance, especially in the caliber 9x19 mm, should only be in the range of up to 200 m. Even at these distances, such projectiles still have sufficient residual energy to cause serious injuries, etc. Such projectiles have no self-destructive mechanisms.

Die US 9,121,679 B1 offenbart ein Geschoss mit einer Regulierung bzw. Begrenzung der Reichweite. Dazu weist das Geschoss neben einem pyrotechnischen Zündsatz ein reaktives Material auf. Der Zündsatz ist in einem Innenraum angeordnet und erstreckt sich vom hinteren Ende des Geschosses nach vorn in den Innenraum. Das reaktive Material umgibt das pyrotechnische Material im Inneren vollständig. Am hinteren Ende des Geschosses kann eine kleine Öffnung ausgebildet und mit einer Membran bedeckt sein. Das reaktive Material hat die Aufgabe, eine Instabilität des Geschosses zu erreichen, das Flugverhalten des Geschosses zu stören. Eine mögliche Nichtletalität des Geschosse ist hierbei nicht vorgehsehen.the US 9,121,679 B1 discloses a bullet with a range regulation. For this purpose, the projectile has a reactive material in addition to a pyrotechnic primer. The primer is located in an interior space and extends forwardly into the interior space from the rear end of the projectile. The reactive material completely surrounds the pyrotechnic material inside. A small opening may be formed at the rear of the bullet and covered with a membrane. The reactive material has the task of making the projectile unstable, disrupting the flight behavior of the projectile. A possible non-lethality of the projectile is not provided for here.

Hier greift die Erfindung die Aufgabe auf, eine Munition aufzuzeigen, die Wirkung (Energie) bis zu einem definierten Entfernungsbereich zu erhalten und die Energie danach sehr schnell abzubauen. Es soll eine vorgebbare Entfernung nicht überschritten werden, damit keine Gefährdung im Hinterland entsteht.Here the invention takes on the task of demonstrating ammunition that maintains the effect (energy) up to a defined distance range and then dissipates the energy very quickly. A predetermined distance should not be exceeded, so that there is no danger in the hinterland.

Gelöst wird die Aufgabe durch die Merkmale des Patentanspruchs 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.The object is achieved by the features of patent claim 1. Advantageous configurations can be found in the dependent claims.

Der Erfindung liegt die Idee zugrunde, eine Munition bzw. ein Geschoss anzugeben, die in einer so genannten Hauptkampfentfernung außenballistisch keinerlei Störungen unterliegt, die dann aber, wenn das Ziel nicht getroffen wurde, deutlich schneller die Geschwindigkeit abbauen kann. Insbesondere bei Übungsmunitionen müssen diese innerhalb der Übungshauptkampfentfernung möglichst identische Eigenschaften vorweisen, wie die entsprechende Gefechtsmunition, dann aber deutlich schneller die Geschwindigkeit abbauen können.The invention is based on the idea of specifying ammunition or a projectile which, at a so-called main combat range, is not subject to any external ballistic interference, but which can then reduce the speed significantly more quickly if the target has not been hit. In the case of training ammunition in particular, these must have properties that are as identical as possible to the corresponding combat ammunition within the training main combat distance, but then be able to reduce the speed much more quickly.

Dieser Geschwindigkeitsabbau erfolgt erfindungsgemäß dadurch, dass sich das Geschoss nach einer bestimmten Zeit bzw. nach einer bestimmten Flugstrecke sich selbst verzehrt, d.h., sich abbaut, sein Gewicht minimiert und sich damit eliminiert. Der Gewichtsabbau und damit die Eliminierung erfolgt dadurch, dass mindestens ein pyrotechnischer Satz im Geschoss eingebunden ist, der das Gewicht bzw. die Masse des Geschosses bestimmt und erst beim Überschreiten der Wirkentfernung gezündet wird. Dadurch verliert das Geschoss über die Flugzeit bzw. Flugstrecke an Gewicht bzw. Masse. Das Geschoss wird über die Brenngeschwindigkeit seines bzw. seiner pyrotechnischen Sätze an die gewünschte Wirkentfernung angepasst.According to the invention, this reduction in velocity takes place in that the projectile consumes itself after a certain time or after a certain flight distance, i.e. it reduces, minimizes its weight and thus eliminates itself. The weight reduction and thus the elimination takes place in that at least one pyrotechnic charge is integrated in the projectile, which determines the weight or the mass of the projectile and is only ignited when the effective distance is exceeded. As a result, the bullet loses weight or mass over the flight time or flight distance. The projectile is adjusted to the desired effective distance via the firing rate of its pyrotechnic charge(s).

Das Geschoss besteht aus einem Geschossmantel, z.B. aus Metall oder einem Kunststoff. Der Mantel ist mit wenigstens einem pyrotechnischen Satz gefüllt. Mantel und pyrotechnischer Satz bilden zusammen das Geschoss, d.h., das Abschuss- und Wirkgewicht die Ausgangsmasse des Geschosses. Ein nicht näher dargestellter Treibladungssatz einer gleichfalls nicht näher dargestellten Munition zündet den pyrotechnischen Satz beim Abschuss. Der pyrotechnische Satz brennt dann während der Flugphase bzw. Flugzeit mit einer definierten Geschwindigkeit ab. Dieses definierte Abbrennen kann durch die Zusammensetzung der pyrotechnischen Mischung des Satzes eingestellt werden. Auch über die Volumenwahl der Sätze ist eine Einstellung möglich. Kombinationen bekannter Möglichkeiten sind dem Fachmann bekannt und bieten sich hier an. Die Brenngeschwindigkeit ist so einzustellen, dass die Geschwindigkeit und Geschossmasse in der definierten Wirkentfernung noch die geforderte Energie besitzen und die Funktionsfähigkeit gewährleisten.The projectile consists of a projectile jacket, for example made of metal or a plastic. The shell is filled with at least one pyrotechnic charge. Jacket and pyrotechnic charge together form the projectile, ie the firing and effective weight the initial mass of the projectile. A propellant charge, not shown in detail, of an ammunition, also not shown in detail, ignites the pyrotechnic charge when it is fired. The pyrotechnic charge then burns off at a defined speed during the flight phase or flight time. This defined burning can be adjusted by the composition of the pyrotechnic mixture of the set. A setting is also possible via the volume selection of the sets. Combinations of known possibilities are known to the person skilled in the art and are available here. The firing speed is to be adjusted in such a way that the speed and projectile mass still have the required energy at the defined effective distance and ensure functionality.

Für einen stufenweisen Abbrand sind zwei oder mehrere Sätze vorzusehen. Bevorzugt sind dann auch unterschiedliche pyrotechnische Sätze eingebunden.Two or more sets are to be provided for a gradual burn-up. Different pyrotechnic charges are then preferably also involved.

Auch die Einbindung von Verzögerungsstrecken (Verzögerungselementen) kann hier vorgesehen werden.The integration of delay sections (delay elements) can also be provided here.

Sobald der pyrotechnische Satz bzw. die pyrotechnischen Sätze abgebrannt ist/sind, bleibt die leichte Hülle übrig, sodass die Restenergie bzw. Restgeschwindigkeit schneller abgebaut wird. Alternativ kann die Hülle beim Abbrand des pyrotechnischen Satzes auch verbrennen, bzw. zeitlich danach, sodass sich das Geschoss vollständig verzehrt. Brennbares Hülsenmaterial ist beispielsweise aus der EP 1 123 482 B1 bekannt.Once the pyrotechnic composition(s) has/have burned off, the lightweight envelope remains, so the residual energy or residual velocity dissipates faster. Alternatively, the casing can also burn when the pyrotechnic charge burns up, or afterwards, so that the projectile is completely consumed. Combustible sleeve material is, for example, from the EP 1 123 482 B1 famous.

Derartige Geschosse sind bevorzugt bei Abschusswinkeln >30° anwendbar, um eine Nichtletalität zu gewährleisten. Wichtig ist, dass bis das Geschoss auf den Boden auftrifft, der pyrotechnische Satz abgebrannt ist, sodass, wenn überhaupt, nur noch die leichten Geschosshüllen mit geringer Restenergie zu Boden fallen. Diese Geschosse sind besonders für eine nicht letale Bekämpfung von Luftzielen bzw. Luftleichtzielen, wie Drohnen, geeignet.Projectiles of this type can preferably be used at firing angles >30° in order to ensure non-lethality. It is important that by the time the projectile hits the ground, the pyrotechnic charge has burned off so that only the light projectile casings with little residual energy fall to the ground, if at all. These projectiles are particularly suitable for non-lethal combating of air targets or light air targets such as drones.

Durch diese konstruktive Maßnahme bzw. Maßnahmen wird gewährleistet, dass für den Wirkbereich bzw. die Wirkentfernung die Munition außenballistisch identische Eigenschaften (Flugbahn) aufweisen wie die entsprechende Gefechtsmunition, eine maximale Gesamt-Reichweite aber nicht überschritten wird. Dadurch wird die Sicherheit im Allgemeinen erhöht.This constructive measure or measures ensures that the ammunition has identical external ballistic properties (trajectory) for the effective range or the effective distance as the corresponding combat ammunition, but a maximum overall range is not exceeded. This increases security in general.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden. Es zeigt die einzige Figur skizzenhaft ein Geschoss 1 mit einem Geschossmantel bzw. Geschosshülle 2 sowie in diesem Ausführungsbeispiel zwei in den Geschossmantel 2 eingebundenen pyrotechnischen Sätzen 3, 4. Beide Sätze 3, 4 ermöglichen einen stufenweisen Abbrand. Das Geschoss 1 bzw. die Geschosshülle 2 weist einen offenen Geschossboden 5 auf, der bis zum Abschuss mit einer zerstörbaren Membran 6 verschlossen ist. Zwischen den beiden pyrotechnischen Sätzen 3, 4 kann eine Membran 7 eingebracht sein.The invention will be explained in more detail using an exemplary embodiment with a drawing. The only figure shows a sketch of a projectile 1 with a projectile casing or projectile casing 2 and, in this exemplary embodiment, two pyrotechnic charges 3, 4 integrated into the projectile casing 2. Both sets 3, 4 enable gradual combustion. The projectile 1 or the projectile casing 2 has an open projectile base 5 which is closed with a destructible membrane 6 until it is fired. A membrane 7 can be inserted between the two pyrotechnic charges 3, 4.

Der pyrotechnische Satz 3 wird beim Abschuss des Geschosses 1 aus einem nicht näher dargestellten Waffenrohr oder Waffenlauf angezündet. Dieses Anzünden kann direkt erfolgen. Der pyrotechnische Satz 3 ist so bemessen (Volumen, Mischung etc.), dass dieser den weiteren pyrotechnischen Satz 4 erst dann entzündet, wenn eine Wirkentfernung für das Geschoss 1 überschritten wird.The pyrotechnic charge 3 is ignited when the projectile 1 is fired from a weapon barrel or weapon barrel, which is not shown in detail. This lighting can be done directly. The pyrotechnic charge 3 is dimensioned (volume, mixture, etc.) such that it only ignites the other pyrotechnic charge 4 when an effective distance for the projectile 1 is exceeded.

Das Anzünden des pyrotechnischen Satzes 3 kann aber auch über eine Verzögerung erfolgen. Verzögerungselemente und deren Einstellung zeigen beispielsweise die DE 10 2013 013 705 A1 , die DE 10 2012 014 1450 A1 oder DE 10 2012 014 149 B3 , auf die hiermit Bezug genommen wird.However, the pyrotechnic charge 3 can also be ignited with a delay. Delay elements and their setting show, for example, the DE 10 2013 013 705 A1 , the DE 10 2012 014 1450 A1 or DE 10 2012 014 149 B3 , which is hereby incorporated by reference.

Durch die Umsetzung der pyrotechnischen Sätze 3 und 4 verliert das Geschoss 1 an Masse bzw. Gewicht. Die Masse tendiert gegen Null. Dadurch wird eine geringe Restmasse des Geschosses 1 außerhalb der Wirkentfernung gewährleistet. Es wird die Sicherheit erhöht und eine nicht letale Wirkung des Restgeschosses insbesondere außerhalb der Wirkentfernung erreicht.Due to the implementation of the pyrotechnic charges 3 and 4, the projectile 1 loses mass or weight. The mass tends towards zero. This ensures a low residual mass of the projectile 1 outside the effective range. Safety is increased and a non-lethal effect of the remaining projectile is achieved, especially outside the effective range.
