Description

Die Erfindung betrifft ein Sicherheitssystem für eine tempierbare Munition, vorzugsweise für eine nicht letale Munition mit nicht letalen Wirkmitteln.The invention relates to a security system for a malleable ammunition, preferably for a non-lethal ammunition with non-lethal agents.

Nicht letale Munitionen finden u. a. Anwendung zum Schutz gegen Bedrohung von Schiffen im Hafenbereich, beispielsweise durch Schnellboote, durch Scharfschützen in Gebäuden oder dergleichen, sowie durch gewaltbereite Menschenmengen. In diesen Szenarien ist die Erkennung der Gefahr erschwert bzw. der Einsatz konventioneller Waffen führt zu nicht gewollten Schäden.Non lethal ammunitions find u. a. Application for protection against threats to ships in the port area, for example by speed boats, by snipers in buildings or the like, as well as by violent crowds. In these scenarios, the recognition of the danger is more difficult or the use of conventional weapons leads to unwanted damage.

Bekannt sind nicht letale Geschosse, die mittels Hochleistungspulsen zielgerichtet ein Zerstören der Elektronik eines Zieles bewirken. Sie können aber auch durch Stören oder durch Blenden die Funktion des Zieles beeinträchtigen.Non-lethal projectiles are known which purposefully destroy the electronics of a target by means of high-power pulses. But you can also interfere with the function of the target by disturbing or blinding.

Eine andere Gattung der nicht letalen Munition enthält nicht letale Wirkmittel, wie beispielsweise Farbe, chemische Reizstoffe, Nebel oder auch Einrichtungen mit Blitz- und Knalleffekten. Sie zeichnet sich zudem dadurch aus, dass sie mit Hilfe einer herkömmlichen Waffenanlage verschossen werden kann, im Ziel aber keine letale Funktion besitzt. Wichtig beim Einsatz derartiger nicht letaler Munitionen ist, dass eine Nichtletalität über die gesamte Flugdauer sichergestellt wird.Another type of non-lethal ammunition contains non-lethal agents, such as color, chemical irritants, fog or even devices with lightning and blast effects. It is also characterized by the fact that it can be fired with the help of a conventional weapon system, but has no lethal function in the target. Important in the use of such non-lethal ammunition is that non-lethality over the entire duration of flight is ensured.

Bekannt sind Vorrichtungen zur Vermeidung gefährlicher Blindgänger, also dann, wenn das eigentliche Ziel nicht erreicht wird oder die Flugphase als beendet gilt, d.h., am Ende der Mission. In diesen Situationen wird im Allgemeinen der Zünder zumindest deaktiviert, beispielsweise durch Sicherstellung des Zünders, oder aber die Munition selbst zerstört. Diverse Zünd- und Sicherungsvorrichtungen mit dem Sicherheitskriterium der so genannten Selbstzerlegung sind aus der DE 43 35 022 C2 , DE 82 36 369 U1 oder der DE 100 40 800 A1 bekannt. Eine elektronische Selbstzerlegereinrichtung benennt die DE 100 20 037 C1 , ein pyrotechnischer Selbstzerleger kann der DE 199 19 001A1 entnommen werden. Insbesondere die DE 100 20 037 C1 besitzt dazu eine Vorrichtung, die eine zeitgesteuerte Selbstzerlegung eines Geschosses bewirkt. Zum Betrieb werden in der Flugphase mehrere während des Abschusses durch ein Piezoelement aufgeladene Kondensatoren verwendet, wobei sichergestellt wird, dass sich Spannungsveränderungen nicht auf die Zeitfunktion auswirken.Devices are known to avoid dangerous duds, so if the actual goal is not achieved or the flight phase is considered to be completed, ie, at the end of the mission. In these situations, the detonator is generally at least deactivated, for example by securing the fuse, or destroying the ammunition itself. Diverse ignition and safety devices with the safety criterion of the so-called self-decomposition are from the DE 43 35 022 C2 . DE 82 36 369 U1 or the DE 100 40 800 A1 known. An electronic self-destructor designates the DE 100 20 037 C1 , a pyrotechnic self-destructor can DE 199 19 001A1 be removed. especially the DE 100 20 037 C1 has a device that causes a time-controlled self-decomposition of a projectile. To operate in the flight phase several during of firing capacitors charged by a piezo element, ensuring that voltage changes do not affect the timing function.

Die DE 698 17 496 T2 beschreibt eine Sicherheitsvorrichtung, bei der die Ladung eines Projektils erst in einem bestimmten Abstand zum Schützen ausgelöst wird, damit dieser keine Splitter abbekommt.The DE 698 17 496 T2 describes a safety device in which the charge of a projectile is triggered only at a certain distance from the shooter so that it does not get splinters.

Die sich stellende Aufgabe liegt nun darin, ein Sicherheitssystem aufzuzeigen, die einen Schutz insbesondere nach Verschuss gewährleistet, da die Nichtletalität entfernungsabhängig und ein Wirkmittel, das in seinem Einsatzbereich nicht letal ausgelegt ist, in anderen Bereichen durchaus in seiner Funktion letal sein kann.The self-evident task is now to show a security system that ensures protection especially after Verschuß, since the non-lethality dependent on distance and an agent that is not designed lethal in its field of application, in other areas can be quite lethal in its function.

Die Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den Unteransprüchen aufgezählt.The object is solved by the features of patent claim 1. Advantageous developments are enumerated in the subclaims.

Der Erfindung liegt die Idee zugrunde, dass mit Verschuss ein vorhandener und / oder zusätzlicher Selbstzerlegungsmechanismus im Projektil aktiviert ist, der so lange aktiv bleibt, bis eine Überprüfung der Zünderfunktion positiv abgeschlossen ist. In diesem Fall wird dieser Mechanismus deaktiviert und die Auslösefunktion erfolgt zum programmierten Zeitpunkt. Die Idee liegt somit darin, die Selbstzerlegungsfunktion, wenn gefordert auch unter Beibehaltung dieser Funktion am Ende der Mission, an den Anfang der Mission zu legen. Dadurch wird auch eine vollständige Nichtletalität der Munition über die gesamte Flugphase / -bahn gewährleistet.The invention is based on the idea that with Verschuss an existing and / or additional self-separation mechanism is activated in the projectile, which remains active until a check of the igniter function is completed positively. In this case, this mechanism is deactivated and the triggering function takes place at the programmed time. The idea is thus to place the self-decomposition function, if required, while maintaining this function at the end of the mission, at the beginning of the mission. This also ensures complete non-lethality of the ammunition over the entire flight phase / course.

Die Munition bzw. das Projektil besitzt bevorzugt einen tempierbaren Zünder. Es sind verschiedene Zeitprogrammierungen und Zünder für Munitionen bekannt. Die Tempierungen erfolgen entweder vor dem Schuss manuell außerhalb des Ladungsraums oder elektrisch im Ladungsraum über eine Anzündelektronik. Letztgenannte Tempierung ist beispielsweise in der DE 101 52 862 A1 beschrieben. Ein Verfahren und eine Vorrichtung zur Übertragung von Informationen auf programmierbare Geschosse sind der EP 0 992 762 B1 entnehmbar. In der EP 0 918 209 B1 wird ein Geschoss mit programmierbarem Zeitzünder offenbart, welches auch als AHEAD- Munition bekannt ist. Ein Verfahren und eine Vorrichtung zum Programmieren von Zeitzündern von Geschossen werden auch in der EP 0 769 673 B1 behandelt. Zur Berechnung einer Zerlegungsdauer werden eine vorbestimmte Mündungsgeschwindigkeit des Geschosses und eine vorbestimmte Distanz zu einem Zielobjekt benutzt.The ammunition or the projectile preferably has a heatable detonator. There are various time programs and detonators for ammunition known. The tempings are done either manually before the shot outside the cargo space or electrically in the cargo space via a Anzündelektronik. The latter temping is for example in the DE 101 52 862 A1 described. A method and a device for transmitting information to programmable projectiles are the EP 0 992 762 B1 removable. In the EP 0 918 209 B1 a bullet with programmable time fuse is disclosed, which is also known as AHEAD ammunition. A method and apparatus for programming firefighters from projectiles are also used in the EP 0 769 673 B1 treated. For calculating a decomposition time, a predetermined muzzle velocity of the projectile and a predetermined distance to a target object are used.

Aus Sicherheitsgründen ist die Zündkette so aufgebaut, dass ein vorzugsweise separater Selbstzerlegungsmechanismus zumindest so lange aktiv bleibt, bis das Geschoss die für die reguläre Zündung erforderliche Zündspannung erreicht hat und die Funktion des Zünders nach einem durchgeführten Selbsttest nachgewiesen ist. In der Zündkette wird die Funktion implantiert, vor Eintritt in den Bereich der nicht letalen Wirkung bei fehlender Zünderfunktion eine Selbstzerlegung des Geschosses einzuleiten. Die Selbstzerlegung wird bei nachgewiesener Zünderfunktion übersteuert wird. Der Selbsttest ist damit ein Sicherheitskriterium.For safety reasons, the ignition chain is constructed such that a preferably separate self-decomposition mechanism remains active at least until the projectile has reached the ignition voltage required for the regular ignition and the function of the igniter is proven after a self-test has been carried out. In the firing chain, the function is implanted to initiate a self-decomposition of the projectile before it enters the area of non-lethal effect in the absence of detonator function. The self-decomposition is overridden when the detonator function is proven. The self-test is thus a safety criterion.

Die Vorteile der vorgeschlagenen Lösung liegen in der Vermeidung von Kollateralschäden insbesondere während einer ersten Flugphase sowie der Neudefinierung der Sicherheits-und Selbstzerlegungskriterien.The advantages of the proposed solution are the avoidance of collateral damage, especially during a first phase of flight, and the redefinition of safety and self-destruction criteria.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden.Reference to an embodiment with drawing, the invention will be explained in more detail.

Die einzige Figur zeigt das Prinzip des Sicherheitssystems für eine nicht letale Munition 1, die von einem Waffensystem 2 verschossen, in der Flugphase B eine aktivierte Selbstzerlegung 3 besitzt und welcher zu einem Zeitpunkt A ein Zündzeitpunktsignal S übertragen wird, beispielsweise durch einen waffenseitigen Feuerleitrechner 4. Der Zeitpunkt A kann der Durchgang der Munition 1 durch eine in der Figur angedeutete Mündungsbremse 5 am Waffensystem 2 oder ein späterer Zeitpunkt sein, wie beispielsweise in der DE 38 35 656 A1 beschrieben. Vorzugsweise bis zum Zündzeitpunkt C bleibt die Selbstzerlegung 3 aktiviert, wobei in dieser Phase eine Überprüfung der Funktion eines Zünders 6 in der Munition 1 abgeschlossen ist. Stellt diese Abfrage ein positives Ergebnis fest, wird spätestens am Zündzeitpunkt C die Selbstzerlegung 3 deaktiviert. Zum Zeitpunkt der Zündung in Punkt C kann dann der Austritt des nicht letalen Wirkmittels (nicht näher dargestellt) erfolgen, wobei die Munition 1 die nicht näher dargestellten Wirkmittel im Punkt D (Zeitpunkt D) frei gibt und sich dabei selbst zerlegt, damit nicht Splitter oder Rückstände der Munition 1 im Ziel selbst letal wirken.The single figure shows the principle of the safety system for a non-lethal ammunition 1, which is fired by a weapon system 2, in the flight phase B has an activated self-decomposition 3 and which at a time A, an ignition timing signal S is transmitted, for example by an arms fire control computer. The point in time A may be the passage of the ammunition 1 through a muzzle brake 5 on the weapon system 2, as indicated in the figure, or a later point in time, such as in FIG DE 38 35 656 A1 described. Preferably, until the ignition time C, the self-decomposition 3 remains activated, wherein in this phase, a check of the function of a fuze 6 in the ammunition 1 is completed. If this query determines a positive result, the self-decomposition 3 is deactivated at the latest at the ignition point C. At the time of ignition in point C then the outlet of the non-lethal agent (not shown), the ammunition 1, the non-illustrated active agent at point D (time D) releases and itself decomposed, so that splinters or Residues of ammunition 1 in the target itself lethal effect.

Wird innerhalb der Zündkette in der Munition 1 eine fehlende Zünderfunktion detektiert, wird mittels weiterer, bekannter Maßnahmen sichergestellt, dass keine Zerlegung der Munition erfolgt und somit das Wirkmittel nicht freigegeben wird. Dabei kann es offen bleiben, ob dies über ein weiteres Signal erfolgt, wodurch der Flug als solches abrupt beendet wird, so dass die Munition nicht in die Nähe des anvisierten Zieles gelangt, oder eine andere Möglichkeit in Erwägung gezogen wird.If a missing igniter function is detected within the firing chain in the ammunition 1, it is ensured by means of further, known measures that no dismantling of the ammunition takes place and thus the active agent is not released. It may remain unclear whether this is done via another signal, whereby the flight itself is terminated abruptly, so that the ammunition does not get in the vicinity of the targeted target, or another possibility is considered.

Bevorzugt ist die Munition 1 eine AHEAD -Munition, welcher der Zeitpunkt der Zündung C über eine Induktionsschleife in der Mündungsbremse 5 der Waffe 2 oder nach Verlassen der Waffe 2 über eine Fernübertragung, wie beispielsweise in der DE 10 2005 024 179.4 beschrieben, übermittelt wird.Preferably, the ammunition 1 is an AHEAD ammunition, which is the time of ignition C via an induction loop in the muzzle brake 5 of the weapon 2 or after leaving the weapon 2 via a remote transmission, such as in the DE 10 2005 024 179.4 described, is transmitted.

Das Ausführungsbeispiel ist aber nicht auf nicht letale Munition beschränkt. Auch eine Einschränkung auf die Nutzung bei so genannten AHEAD- oder ABM ― Munitionen ist nicht gegeben. Vielmehr sind sämtliche, in der Regel tempierbare Geschosse eingeschlossen.The embodiment is not limited to non-lethal ammunition. There is also no restriction on the use of so-called AHEAD or ABM ammunition. Rather, all, usually malleable bullets are included.
