Abstract

The invention relates to ammunition comprising a launcher (1) and an active charge (2) to be fired from the latter, the active charge being propelled from the launcher with the aid of a propulsive charge (14). According to the invention, it is proposed that the launcher (1) has in the bottom region an electromagnetic coil (6), which can be connected to an electrical supply source and has a movably mounted armature (10), the armature being designed as a striker pin (10) for a percussion cap (13), which fires the propulsive charge (14). In this way, the previously customary electrical ignition of the propulsive charge (14) is replaced by a reliable striker-pin ignition (5). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Munition aus einem Wurfbecher und einem Wirkkörper gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an ammunition consisting of a throwing cup and an active body according to the preamble of claim 1.

Eine solche Munition dient vornehmlich dem Selbstschutz von Fahrzeugen, insbesondere von Kampfpanzern. Die Wirkkörper, z. B. Nebelwurfkörper werden aus Wurfbechern verschossen, die an dem Kampfpanzer befestigt sind, um in einiger Entfernung von dem zu schützenden Fahrzeug Nebel zu erzeugen und im Schutze dieses Nebels z. B. einen Stellungswechsel vorzunehmen; vgl. etwa die DE-A-35 01 468.Such ammunition is used primarily for the self-protection of vehicles, in particular main battle tanks. The active bodies, e.g. B. smoke missiles are fired from throwing cups which are attached to the main battle tank in order to generate fog at some distance from the vehicle to be protected and under the protection of this fog z. B. make a change of position; see. such as DE-A-35 01 468.

Wurfbecher weisen in ihrem unteren Seitenbereich in das Becherinnere ragende Kontaktstifte auf, die über einen Anschlußblock mit einer externen elektrischen Versorgungsquelle verbunden sind. In einen solchen Wurfbecher wird der Wirkkörper eingesetzt, der aus einem Wirkladungsteil mit z. B. einer Nebelladung und einem Kontaktkopf besteht. In dem Kontaktkopf ist eine Treibkammer mit einer Treibladung vorgesehen, die elektrisch gezündet wird. Die Zündenergie für eine Zündpille oder dgl. wird dem Kontaktkopf über die Kontaktstifte im Wurfbecher und Kontaktringe am Umfang des Kontaktkopfes zugeführt. In dem Kontaktkopf sind ferner Schutzschaltungen gegen elektromagnetische Störungen, sog. EMV-Schaltungen vorgesehen. Nach dem Zünden der Treibladung strömen die Treibgase aus Ausblasöffnungen am Boden des Wirkkörpers in den Wurfbecher, so daß durch den sich aufbauenden Gasdruck zwischen dem Boden des Wurfbechers und dem Wirkkörper dieser aus dem Wurfbecher ausgestoßen wird.Throw cups have contact pins projecting into the cup interior in their lower side area, which are connected to an external electrical supply source via a connection block. In such a throwing cup, the active body is used, which consists of an active charge part with z. B. there is a fog charge and a contact head. A propellant chamber with a propellant charge is provided in the contact head and is electrically ignited. The ignition energy for a squib or the like is supplied to the contact head via the contact pins in the throwing cup and contact rings on the circumference of the contact head. Protection circuits against electromagnetic interference, so-called EMC circuits, are also provided in the contact head. After the propellant charge is ignited, the propellant gases flow out Blow-out openings at the bottom of the active body into the throwing cup, so that the gas pressure which builds up between the bottom of the throwing cup and the active body pushes it out of the throwing cup.

Die Treibgase verschmutzen jedoch die Kontaktstifte, so daß diese routinemäßig gereinigt werden müssen, um einen für die Zündung der Treibladung notwendigen sauberen elektrischen Kontakt zwischen den Kontaktstiften und den Kontaktringen zu gewährleisten. Bisher ist es nicht gelungen, dieses Problem zu lösen.However, the propellant gases contaminate the contact pins, so that they have to be routinely cleaned in order to ensure a clean electrical contact between the contact pins and the contact rings necessary for the ignition of the propellant charge. So far, this problem has not been solved.

Der Kontaktkopf, der die Treibkammer mit der Treibladung sowie Zündeinrichtungen für die Treibladung und die EMV-Schaltungen enthält, wird mit dem Wirkkörper verschossen. Allein die somit nur einmal verwendeten EMV-Schaltungen im Kontaktkopf sind relativ aufwendig und teuer, da die elektrisch initiierte Zündladung für die Treibladung schon auf relativ geringe Störströme reagiert. Eine einfachere Konstruktion wäre wünschenswert, um u. a. die Herstellungskosten von Wurfbecher und Wirkkörper zu reduzieren.The contact head, which contains the propellant chamber with the propellant charge as well as ignition devices for the propellant charge and the EMC circuits, is fired with the active body. The EMC circuits in the contact head, which are used only once, are relatively complex and expensive, since the electrically initiated ignition charge for the propellant charge already reacts to relatively low interference currents. A simpler construction would be desirable to u. a. reduce the manufacturing costs of throwing cups and active bodies.

Die bisherigen Konstruktionen von Wirkkörpern sind ferner sämtlich auf vorhandene Wurfbecher abgestellt und dahingehend ausgerichtet, daß im Wurfbecher ein maximaler Gasdruck im Bereich von etwa 13 bar nicht überschritten wird. Bei höheren Gasdrücken könnten die Führungen der beweglichen Kontaktstifte zerstört und der Bodendeckel vom Wurfbecher abgesprengt werden. Um mit solchen Gasdrücken die Mindestwurfweiten zu erreichen oder gar zu überschreiten, sind spezielle Ausbildungen der Treibkammer und der Ausblasöffnungen notwendig; vgl. die DE-A-35 01 468. Mit höheren, jedoch bislang von Wurfbechern nicht erträglichen Gasdrücken, die auch einfachere Konstruktionen der Treibkammer und der Ausblasöffnungen erlaubten, waren gleiche oder weitere Wurfweiten der Wirkkörper erzielbar.The previous designs of active bodies are also all based on existing throwing cups and are oriented in such a way that a maximum gas pressure in the range of approximately 13 bar is not exceeded in the throwing cup. At higher gas pressures, the guides of the movable contact pins could be destroyed and the bottom cover of the throwing cup could be blown off. In order to reach or even exceed the minimum throw distances with such gas pressures, special designs of the drive chamber and the blow-out openings are necessary; see. DE-A-35 01 468. With higher gas pressures, which were not yet tolerable by throwing cups and which also allowed simpler constructions of the drive chamber and the blow-out openings, the same or further throwing distances of the active bodies could be achieved.

Alle bekannten Lösungen erfüllen die genannten Zielvorstellungen nur unvollkommen.All known solutions only incompletely meet the stated objectives.

Der Erfindung liegt daher die Aufgabe zugrunde, für eine Munition aus Wurfbecher und Wirkkörper eine einfachere Konstruktion anzugeben, mit der diese Zielvorstellungen erreicht werden können, das sind insbesondere Konstaktsicherheit bei der Zündung der Treibladung, Erzielung großer Wurfweiten, geringe elektromagnetische Störanfälligkeit und geringe Herstellungskosten. Ferner wird angestrebt, bisher verwendete Wurfbecher ohne großen Aufwand umrüsten zu können.The invention is therefore based on the object of specifying a simpler construction for an ammunition consisting of a throwing cup and active body, with which these objectives can be achieved, that is, in particular, reliability of contact in the ignition of the propellant charge, achieving long throw ranges, low susceptibility to electromagnetic interference and low manufacturing costs. Furthermore, the aim is to be able to retrofit throwing cups used without great effort.

Diese Aufgabe ist gemäß der Erfindung durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the features specified in the characterizing part of patent claim 1.

Ein wesentlicher Gedanke der Erfindung liegt demgemäß darin, die bisher übliche Zündung der Treibladung über eine elektrisch initiierte Zündladung durch eine Schlagbolzenzündung zu ersetzen. Das Zünden von Ladungen durch Schlagbolzen ist natürlich bekannt vgl. etwa die DE-A1-2 404 053, in der eine derartige Schlagbolzenzündung für Pistolen, Druckluftgewehre oder automatischen Waffen beschrieben ist. In dem vorliegenden Fall, d. h. dem Zünden einer Treibladung zum Ausstoßen einer Wirkladung, z. B. eines Nebelwurfkörpers, aus einem Wurfbecher bringt eine Schlagbolzen- bzw. Perkussionszündung jedoch überraschende Vorteile.An essential idea of the invention is accordingly to replace the previously usual ignition of the propellant charge by means of an electrically initiated ignition charge by firing a firing pin. The ignition of charges by firing bolts is of course known, cf. about DE-A1-2 404 053, in which such a firing pin firing for pistols, compressed air rifles or automatic weapons is described. In the present case, ie the ignition of a propellant charge to eject a real charge, e.g. B. a smoke missile, firing a firing pin or percussion ignition brings surprising advantages.

Die elektrischen Anschlüsse für die Betätigung des Schlagbolzens werden nicht wie die bisherigen Kontaktstifte durch die Treibgase der Treibladung beim Abschuß des Wirkkörpers verschmutzt, da die Treibgase gar nicht an diese Anschlüsse gelangen. Eine Zündung der Treibladung ist daher immer gewährleistet.The electrical connections for the actuation of the firing pin are not, like the previous contact pins, soiled by the propellant gases of the propellant charge when the active body is fired, since the propellant gases do not reach these connections at all. An ignition of the propellant charge is therefore always guaranteed.

Der Wirkkörper benötigt keinen eigenen Kontaktkopf, wodurch die Herstellungskosten für die Munition reduziert werden.The active body does not need its own contact head, which reduces the production costs for the ammunition.

EMV-Schaltungen sind nicht notwendig, da der Schlagbolzen als Anker der Elektromagnetspule nur mit hohen, durch Störimpulse nicht erreichbaren Stromstößen bewegt werden kann.EMC circuits are not necessary because the firing pin as the armature of the electromagnetic coil can only be moved with high current surges that cannot be reached by interference pulses.

Der Wirkkörper ist gemäß der Erfindung ferner in eine Patronenhülse eingesetzt, wobei dann die Patronenhülse beim Ausstoß des Wirkkörpers aus dem Wurfbecher in diesem verbleibt. Der Vorteil hierbei ist, daß der durch das Treibgas erzeugte Gasdruck nur zwischen Wirkladung und Patronenhülse, nicht jedoch auf den Wurfbecher wirkt. Dieser muß nur die Rückstoßkräfte aufgrund der Beschleunigung des Wirkkörpers aufnehmen. Der Wirkkörper kann dadurch mit wesentlich höheren Gasdrücken ausgestoßen werden als dies bisher möglich war. Bei einer solchen Konstruktion verbleibt der Wurfbecher nach dem Abschuß verschlossen und kann nicht verschmutzt werden.According to the invention, the active body is also inserted into a cartridge case, the cartridge case then remaining in the throw cup when the active body is ejected from the throw cup. The advantage here is that the gas pressure generated by the propellant only acts between the active charge and the cartridge case, but not on the throwing cup. This only has to absorb the recoil forces due to the acceleration of the active body. The active body can thereby be expelled at significantly higher gas pressures than was previously possible. With such a construction, the throwing cup remains closed after firing and cannot be soiled.

Weitere Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further embodiments of the invention emerge from the subclaims.

Die in Fig. 1 dargestellte Munition besteht aus einem zylindrischen Wurfbecher 1 und einem darin eingesetzten Wirkkörper 2, z. B. einem Nebelwurfkörper. Der Wurfbecher 1 ist am Boden mit einem abschraubbaren Bodendeckel 3 verschlossen, der nach Art einer Dose ausgebildet ist und in dessen Innenraum 4 ein Schlagbolzenzünder 5 angeordnet ist. Der Schlagbolzenzünder weist eine Elektromagnetspule 6 auf, die auf einen Spulenträger 7 gewickelt ist und die über eine Ansteuerschaltung 8 mit elektrischen Anschlüssen 9 verbunden ist, die zu einer nicht dargestellten Versorgungsquelle führen. Als Anker der Elektromagnetspule 6 ist ein Schlagbolzen 10 vorgesehen, der in der Mittelbohrung des Spulenträgers 7 gelagert ist und im Bereich seiner Spitze in einer Bohrung 11 einer Erhebung 12 an der Oberseite des Bodendeckels 3 geführt ist. Die Längsachse des Schlagbolzens 10 liegt in der Mittellängsachse A von Wurfbecher und Nebelwurfkörper. Der Nebelwurfkörper 2 liegt mit seinem Boden auf der Oberseite der Erhebung 12 und trägt dort ein Anzündhütchen 13 für eine nur angedeutete Treibladung 14.The ammunition shown in Fig. 1 consists of a cylindrical shot cup 1 and an active body 2 inserted therein, for. B. a smoke missile. The throwing cup 1 is closed at the bottom with a screwable bottom cover 3 which is designed in the manner of a can and in the interior 4 of which a firing pin igniter 5 is arranged. The firing pin igniter has an electromagnetic coil 6 which is wound on a coil carrier 7 and which is connected via a control circuit 8 to electrical connections 9 which lead to a supply source (not shown). A firing pin 10 is provided as the armature of the electromagnetic coil 6, which is mounted in the central bore of the coil carrier 7 and in the region of its tip in a bore 11 a survey 12 is performed on the top of the bottom cover 3. The longitudinal axis of the firing pin 10 lies in the central longitudinal axis A of the throwing cup and the smoke projectile. The base of the smoke throwing body 2 lies on the top of the elevation 12 and there carries an ignition cap 13 for a propellant charge 14, which is only indicated.

Wird die Elektromagnetspule 6 aktiviert, so schnellt der Schlagbolzen 10 in Richtung auf das Anzündhütchen 13 und initiiert dieses, wodurch die Treibladung 14 gezündet wird. Die bei der Verbrennung der Treibladung 14 erzeugten Treibgase treten aus Ausblasöffnungen 15 in den freien Raum zwischen Unterseite des Nebelwurfkörpers 2 und Oberseite des Bodendeckels 3 in den Wurfbecher 1, so daß hier ein Gasdruck erzeugt wird, der den Nebelwurfkörper 2 aus dem Wurfbecher 1 ausstößt. Die Treibgase gelangen dabei nicht in den Bereich der elektrischen Anschlüsse für die Elektromagnetspule, so daß diese durch Treibgase auch nicht verschmutzt werden.If the electromagnetic coil 6 is activated, the firing pin 10 snaps in the direction of the primer 13 and initiates this, as a result of which the propellant charge 14 is ignited. The propellant gases generated during the combustion of the propellant charge 14 emerge from blow-out openings 15 into the free space between the underside of the mist launcher 2 and the top of the base cover 3 in the throwing cup 1, so that a gas pressure is generated here which ejects the mist throwing body 2 from the throwing cup 1. The propellant gases do not reach the area of the electrical connections for the electromagnetic coil, so that they are not contaminated by propellant gases.

In Fig. 2 ist ein Wurfbecher 1a dargestellt, der bis auf den Bodendeckel 3a herkömmlichen Wurfbechern gleicht. Dieser Wurfbecher weist im unteren Seitenbereich einen Anschlußblock 21 auf, der über elektrische Anschlüsse 8 mit einer nicht dargestellten elektrischen Versorgungsquelle verbunden ist. In dem Anschlußblock 21 sind Anpaß- und EMV-Schaltungen vorgesehen, die die elektrischen Anschlüsse 9 mit zwei Kontaktstiften 22 verbinden, die in das Innere des Wurfbechers 1a hineinragen. Der Bodendeckel 3a, der hinsichtlich der Schlagbolzenzündung genauso aufgebaut ist wie der Bodendeckel 3 gemäß Fig. 1, weist einen von seiner Oberseite ausgehenden zylindrischen Steg 23 auf, der an seinem Umfang mit zwei Kontaktringen 24 versehen ist, die in elektrischem Kontakt mit den Kontaktstiften 22 stehen. Von den Kontaktringen 24 führen hier nicht gezeigte Leitungen zu der Elektromagnetspule des Schlagbolzenzünders.In Fig. 2, a throw cup 1a is shown, which is similar to conventional throw cups except for the bottom cover 3a. This throw cup has a connection block 21 in the lower side area, which is connected via electrical connections 8 to an electrical supply source, not shown. In the connection block 21, matching and EMC circuits are provided which connect the electrical connections 9 to two contact pins 22 which protrude into the interior of the throwing cup 1a. The bottom cover 3a, which is constructed in the same way with respect to the firing pin ignition as the bottom cover 3 according to FIG. 1, has one of its On the outgoing cylindrical web 23, which is provided on its circumference with two contact rings 24 which are in electrical contact with the contact pins 22. Cables (not shown) lead from the contact rings 24 to the electromagnetic coil of the firing pin igniter.

Diese Ausführungsform hat den Vorteil, daß herkömmliche Wurfbecher einfach durch Austauschen des Bodendeckels gegen einen modifizierten Bodendeckel 3a auf eine Schlagbolzenzündung gemäß der Erfindung umgerüstet werden können.This embodiment has the advantage that conventional throwing cups can be converted to a firing pin ignition according to the invention simply by replacing the bottom cover with a modified bottom cover 3a.

In Fig. 3 ist ein Nebelwurfkörper 2 dargestellt, der aus Wurfbechern gemäß den Fig. 1 und 2 abgeschossen werden kann. Der Nebelwurfkörper 2, der üblicherweise mit einer Gummikappe 31 abgedeckt ist, weist an seinem Boden einen nach unten weisenden zylindrischen Fortsatz 32 auf, der bei eingesetztem Wurfkörper auf der Erhebung 12 des Bodendeckels 3 liegt. In dem zylindrischen Fortsatz 32 ist das Anzündhütchen 13 und die Treibladung 14 vorgesehen. Mehrere Ausblasöffnungen 15 sind um das Anzündhütchen 13 gelegt. Die Treibladung 14 zündet ferner eine hier nur angedeutete Verzögerungsladung 33, mit der die in dem Wurfkörper 2 enthaltene Wirkladung, z. B. ein Nebelsalz gezündet wird.In Fig. 3, a smoke missile 2 is shown, which can be shot from throwing cups according to FIGS. 1 and 2. The mist launcher 2, which is usually covered with a rubber cap 31, has on its bottom a downward-pointing cylindrical extension 32, which lies on the elevation 12 of the bottom cover 3 when the launcher is inserted. The primer 13 and the propellant charge 14 are provided in the cylindrical extension 32. Several blow-out openings 15 are placed around the primer 13. The propellant charge 14 also ignites a delay charge 33, only indicated here, with which the active charge contained in the throwing body 2, e.g. B. a fog salt is ignited.

In Fig. 4 ist ein Wirkkörper 2a in Art einer Patronenmunition dargestellt. Er besteht aus einer Hülse 41, z. B. aus Stahl und einem darin eingesetzten, eine Wirkladung enthaltenden Nebelwurfkörper 42. Hülse und Nebelwurfkörper sind an ihrer Oberseite mit einer Gummikappe 31 abgedichtet. Im flachen Boden der Hülse 41 ist mittig das Anzündhütchen 13 eingesetzt, durch das die in dem Boden der Hülse 41 angeordnete Treibladung 14 gezündet wird. In dem Wurfkörper 42 ist wiederum eine nur angedeutete Verzögerungsladung 33 für die Wirkladung des Wirkkörpers gelegen, die durch die Treibladung 14 angezündet wird.4 shows an active body 2a in the manner of a cartridge ammunition. It consists of a sleeve 41, for. B. made of steel and a smoke charge body 42 inserted therein, containing an active charge. The sleeve and smoke body are sealed on their upper side with a rubber cap 31. In the flat bottom of the sleeve 41 the primer 13 is inserted in the center, by means of which the propellant charge 14 arranged in the bottom of the sleeve 41 is ignited. In the throwing body 42 there is in turn an only indicated delay charge 33 for the active charge of the active body, which is ignited by the propellant charge 14.

Zum Abschuß wird die dargestellte Munition aus Hülse 41 und Wirkkörper 42 in einen Wurfbecher gemäß Fig.1 oder 2 eingesetzt. Die Gummikappe umgreift mit einem Randbereich 31a den oberen Rand des Wurfbechers. Längs des oberen Randes des Wirkkörpers 42 weist die Gummikappe einen Stanzschnitt oder eine Sollbruchstelle 43 auf, so daß die Gummikappe in Randbereich 31a und einen Deckelbereich 31b unterteilt ist. Wird das Anzündhütchen 13 durch den Schlagbolzenzünder angezündet, so brennt die Treibladung 14 ab und erzeugt zwischen dem Boden der Hülse 41 und dem Wirkkörper 42 einen Gasdruck, durch den der Wirkkörper 42 mit dem Deckelbereich 31b der Gummikappe 31 aus der Hülse 41 ausgestoßen wird. Die Hülse 41 verbleibt beim Abschuß in dem Wurfbecher, wobei auch der Randbereich 31a der Gummikappe 31 an seinem Platz bleibt und den Wurfbecher weiterhin verschließt. Das Innere des Wurfbechers kann somit auch dann nicht etwa durch Regen oder Schmutz verunreinigt werden. Vor dem nächsten Abschuß wird die Hülse 41 aus dem Wurfbecher entfernt und eine neue Patronenmunition aus Hülse und Wirkkörper eingesetzt. Mit einer solchen Konstruktion kann der Wirkkörper 42 mit hoben Gasdrücken ausgestoßen werden.To shoot, the ammunition shown from the sleeve 41 and the active body 42 is inserted into a shot cup according to FIG. 1 or 2. The rubber cap surrounds the upper edge of the throwing cup with an edge region 31a. Along the upper edge of the active body 42, the rubber cap has a punch cut or a predetermined breaking point 43, so that the rubber cap is divided into edge region 31a and a cover region 31b. If the primer cap 13 is ignited by the firing pin igniter, the propellant charge 14 burns off and generates a gas pressure between the bottom of the sleeve 41 and the active body 42, through which the active body 42 with the cover region 31b of the rubber cap 31 is ejected from the sleeve 41. The sleeve 41 remains in the throw cup when it is fired, the edge region 31a of the rubber cap 31 also remaining in place and continuing to close the throw cup. The inside of the throwing cup cannot be contaminated by rain or dirt. Before the next launch, the sleeve 41 is removed from the throwing cup and a new cartridge ammunition consisting of the sleeve and the active body is inserted. With such a construction, the active body 42 can be ejected with raised gas pressures.
