Description

BESCHREIBUNG  DESCRIPTION
Wirkteilzünder für eine Mörsergranate und aus einem Zapfenmörser verschießbare Impact particle igniter for a mortar shell and from a mortise mortar shootable
Mörsergranate mit einem derartigen Wirkteilzünder  Mortar shell with such an active part fuze
Die Erfindung betrifft den Wirkteilzünder einer Mörsergranate. Ferner bezieht sich die Erfindung auf eine aus einem Zapfenmörser (auch als Spigot Mörser oder Fly-K Mörser bezeichnet) verschießbare, mit einem derartigen Wirkteilzünder versehene Mörsergranate. Ausganspunkt der Erfindung ist die Schaffung einer treibladungspulvergas-initiierten Zündersicherung für einen mechanisch wirkenden Bodenzünder, beispielsweise einer Fly- k-Mörsergranate. The invention relates to the active partial igniter of a mortar shell. Furthermore, the invention relates to a mortar from a mortar (also known as Spigot mortar or Fly-K mortar), provided with such an active part igniter mortar shell. The starting point of the invention is the provision of a spark ignition powder gas-initiated fuze fuse for a mechanically acting bottom detonator, for example a fly-k mortar shell.
Aus einem Zapfenmörser verschießbare Mörsergranaten sind beispielsweise aus dem Buch von lan V. Hogg:„Munition für Leichtwaffen Mörser und Artillerie", LAufl. 1989, Motorbuch Verlag, Stuttgart, Seite 106f. und 138f. bekannt. Sie bestehen üblicherweise aus einem als Treibrohr dienenden hohlen Leitwerksteil, der wirkteilseitig durch einen Stoßboden begrenzt ist. Im Inneren des Treibrohres stützt sich über eine Treibladung ein Treibkolben an dem Stoßboden ab. Der Wirkteilzünder ist dabei häufig als Bodenzünder ausgebildet. Mortar shells which can be fired from a mortar are known, for example, from the book by lan V. Hogg: "Ammunition for Light Weapons, Mortars and Artillery", LAufl., 1989, Motorbuch Verlag, Stuttgart, pages 106f and 138f They usually consist of a serving as a driving tube In the interior of the driving tube, a driving piston is supported by a propellant charge on the thrusting surface, the active part igniter being often designed as a bottom igniter.
Zum Abfeuern einer Mörsergranate wird das hohle Leitwerksteil der Mörsergranate über den Zapfen (Spigot) geschoben. Dieses erfährt dadurch zunächst eine ausreichende Positionierung bzw. Führung. Zentrisch im Inneren dieses Spigots befindet sich waffenseitig ein Zündnadelmechanismus, welcher beim Abschuss einen Schlagkontakt auf ein An- zündhütchen tätigt. Dieses Anzündhütchen wiederum befindet sich munitionsseitig in einem, in oberer Position dieses hohlen Leitwerksteiles befindlichen Treibkolben. Mit dem Schlagkontakt vom waffenseitigen Zündnadelmechanismus erfolgt über dieses Anzündhütchen die Initiierung jenes in diesem Kolben befindlichen Treibladungspulvers. Jene hieraufhin expandierenden Treibladungspulvergase treiben sodann diesen Kolben im hohlen Leitwerksteil rückwärtig (also entgegen der Schussrichtung) rasant nach unten, wodurch sich die Fly-k-Granate, abstützend vom Spigot, mit hoher Geschwindigkeit entgegengesetzt vorwärts von diesem entfernt und hierüber den kontrolliert beherrschbaren Abschuss herbeiführt. In der unteren finalen Position beim Durchgang dieses Treibkolbens durch das hohle Antriebsteil wird dieser sodann dort gasdicht gefangen, was jene ansonsten mörserübliche übliche Abschusssignatur (Knall/Rauch/Lichtblitz) hier erheblich minimiert. Der Treibladungsanzünder wird also beispielsweise durch einen Schlagbolzen, der in den Zapfen eingelassen ist, gezündet. Dadurch wird der Treibkolben durch die Treibladungsgase mit hoher Kraft und Geschwindigkeit zum heckseitigen Ende der Mörsergranate bewegt. Diese Bewegung wirkt auf den Zapfen des Mörsers und die Mörsergranate wird mit ihrem eine Wirkladung (z.B. Sprengladung) einhaltenden Wirkteil (Gefechtskopf) in die Luft geschleudert. To fire a mortar shell, the hollow tail part of the mortar shell over the pin (spigot) is pushed. This first experiences sufficient positioning or guidance. Centrally inside this spigot there is a firing needle mechanism on the weapon side, which makes a striking contact on a firing cap when firing. This primer cap is in turn located ammunition side in a, located in the upper position of this hollow tail section driving piston. With the impact of the weapon-side Zündnadelmechanismus done via this primer the initiation of that located in this piston propellant charge powder. Those In this case, expanding propellant charge powder gases then drive this piston in the hollow tail part backwards (ie counter to the firing direction) down rapidly, causing the fly-k grenade, supported by the spigot, at high speed opposite forward of this and hereby brought about controlled controlled launch. In the lower final position during the passage of this drive piston through the hollow drive part of this is then trapped there gas-tight, which significantly minimizes that otherwise usual mortar usual Abschusssignatur (bang / smoke / flash of light) here. The propellant charge igniter is thus ignited, for example by a firing pin, which is embedded in the pin. Thereby, the driving piston is moved by the propellant gases with high power and speed to the tail end of the mortar shell. This movement acts on the pin of the mortar and the mortar shell is thrown with its one active charge (eg explosive charge) completing active part (warhead) in the air.
Zur Vermeidung einer unbeabsichtigten Aktivierung der Wirkladung während des Transportes der Mörsergranate oder vor Erreichung des Zieles wird bei bekannten, derartigen Mörsergranaten als Sicherheitseinrichtung häufig ein durch die Abschussbeschleunigung verschiebbarer Sicherungsbolzen verwendet. Dieser greift zunächst in eine Ausnehmung eines schwenkbaren Detonatorträgers des Geschosszünders ein und hält diesen in seiner gesicherten Position, so dass der Detonator außerhalb der Fluchtung einer Zündkette gehalten wird, durch welche die Wirkladung zündbar ist. Sobald die Abschussbeschleunigung der Mörsergranate einen vorgegebenen Wert erreicht hat, wird der Sicherungsbolzen gegen den Druck eines elastischen Rückstellelementes (Feder) axial verschoben und der Detonatorträger freigegeben, so dass dieser (beispielsweise durch eine vorgespannte Drehfeder) in seine Zündposition geschwenkt und der Detonator in Fluchtung mit einer Anstichnadel gebracht wird. In order to avoid unintentional activation of the active charge during transport of the mortar shell or before reaching the target is used in known, such mortar shells as a safety device often displaceable by the firing acceleration securing bolt. This first engages in a recess of a pivotable Detonatorträgers of the projectile fuse and keeps it in its secure position, so that the detonator is held outside the alignment of a detonating chain, through which the effective charge is ignited. Once the firing acceleration of the mortar shell has reached a predetermined value, the locking pin is axially displaced against the pressure of an elastic return element (spring) and the Detonatorträger released so that this (for example, by a preloaded torsion spring) pivoted to its firing position and the detonator in alignment with a puncture needle is brought.
Ähnlich wie bei drallstabilisierten Artilleriegeschossen wird auch bei aus glatten Rohren verschießbaren Mörsergranaten häufig gefordert, dass der Geschosszünder zusätzlich zu der bekannten Sicherheitseinrichtung eine weitere Sicherheitseinrichtung umfasst, die unabhängig von der Abschussbeschleunigung wirkt. Insbesondere sehen die durch die NATO erlassenen Vorschriften (STANANG 4157 und/oder MIL-STD-1316E) das Vorhandensein einer derartigen zweiten Sicherheitseinrichtung vor. Similar to spin-stabilized artillery shells, mortar shells which can be fired from smooth pipes are frequently required, in addition to the known safety device, to include a safety device which acts independently of the launch acceleration. In particular, the rules adopted by NATO (STANANG 4157 and / or MIL-STD-1316E) provide for the existence of such a second security device.
Aus der DE 198 31 645 A1 ist bekannt, bei Mörsergranaten mit Kopfzünder als weitere Sicherheitseinrichtung den Druckabfall des Luftstromes heranzuziehen, der sich beim Flug der Mörsergranate entlang der spitzbogenförmigen Gestalt des Zünderkörpers ergibt. From DE 198 31 645 A1 it is known to use the pressure drop of the air stream in mortar shells with head detonator as a further safety device, which occurs during the Flight of the mortar shell along the pointed arch shape of the fuse body results.
Eine derartige Lösung wäre bei Verwendung einer Mörsergranate mit bodenseitig angeordnetem Wirkteilzünder nur sehr aufwendig realisierbar, sofern diese Sicherheitseinrichtung ohne Zwischenschaltung elektrischer oder elektronischer Systeme direkt auf den Detonatorträger des Zünders wirken soll. Such a solution would be very expensive to implement when using a mortar shell with bottom side arranged active partial igniters, if this safety device should act directly on the Detonatorträger the igniter without the interposition of electrical or electronic systems.
Der Erfindung liegt die Aufgabe zugrunde, einen Wirkteilzünder für eine Mörsergranate, insbesondere für eine aus einem Zapfenmörser verschießbare Mörsergranate mit bodenseitig (stoßbodenseitig) angeordnetem Wirkteilzünder zu offenbaren, die ein Sicherungssystem zur Vermeidung einer unbeabsichtigten Aktivierung der Wirkladung enthält, dessen Funktionsweise im Wesentlichen unabhängig von der Abschussbeschleunigung der Mörsergranate ist. Ferner soll eine aus einem Zapfenmörser verschießbare, mit einem derartigen Wirkteilzünder versehene Mörsergranate offenbart werden. The invention has for its object to disclose an active partial igniter for a mortar shell, in particular for a mortar mortar fireable from a mortar with bottom side (bottom side) arranged Wirkteilzünder containing a security system to prevent inadvertent activation of the active charge, whose operation is essentially independent of the Mortar Grenade launch acceleration is. Furthermore, it is intended to disclose a mortar shell which can be fired from a mortise and mortar, provided with such an active particle igniter.
Diese Aufgabe wird erfindungsgemäß hinsichtlich des Wirkteilzünders durch die Merkmale des Anspruchs 1 und hinsichtlich der Mörsergranate durch die Merkmale des Anspruchs 4 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche. This object is achieved with respect to the active part igniter by the features of claim 1 and with respect to the mortar shell by the features of claim 4. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
Das Wesen dieser Erfindung besteht darin, nach konstruktionstechnisch minimalinvasiven Maßstäben und unter hinreichender Berücksichtigung jener Fly-k-spezifischen Bauartbesonderheiten, bzw. der funktionell unveränderten Beibehaltung derselben, hier eine zweite Sicherungsvorrichtung in dieses Design zu implementieren. In diesem Zusammenhang greift diese Erfindung darauf zurück, anteilig expandierende Treibladungsgase bypassartig durch den geschoßseitigen Stoßboden hindurch zu führen und derart kontrolliert auf die Frontseite eines in Schussrichtung vorzugsweise nunmehr quer und gas- schlupfdicht verbauten Scherkragenbolzen zu leiten. Da bei einem regulären Abschuss von Fly-k-Granaten das Druckniveau der Abschussgase einem Vielfachen der Scherkraft im Kragen von diesem Scherkragenbolzen entspricht, ist hierüber in Verbindung mit der bereits hierzu vorhandenen ersten Sicherungsvorrichtung (g-Schalter mit nachgeschaltetem Hemmwerk) sichergestellt, dass periphere Kräfte hier zu keiner irregulären Zünderauslösung führen können. Die Erfindung beruht daher im Wesentlichen auf dem Gedanken, daß der Wirkteilzünder einen von einer gesicherten Position in eine Zündposition schwenkbaren Detonatorträger umfasst, der mit einer ersten Sicherungseinrichtung in Wirkverbindung steht, die, bei ihrer bestimmungsgemäßen Verwendung, einen sich in Längsrichtung der entsprechenden Mörsergranate erstreckenden, durch eine Feder belasteten Sperrstift umfasst, welcher sich mit seinem ersten Ende an einem Scherbolzen abstützt. Dabei ist der Scherbolzen innerhalb einer Querbohrung angeordnet und weist auf seiner dem ersten Ende des Sperrbolzens zugewandten Seite eine Führungskontur auf, derart, dass in der gesicherten Position des Detonatorträgers das zweite Ende des Sperrbolzens gegen den Druck der Feder in eine Ausnehmung des Detonatorträgers gedrückt wird und eine Schwenkbewegung des Detonatorträgers in seine Zündposition verhindert. Die Querbohrung weist eine Verbindungsbohrung auf, über welche die beim Abschuss der entsprechenden Mörsergranate Treibladungsgase in die Querbohrung gelangen können und dort eine Druckerhöhung bewirken, die ausreicht, um den mit der Führungskontur versehenen Teil des Scherbolzens von dem restlichen Teil des Scherbolzens abzutrennen und entlang der Querbohrung in Richtung auf die Außenwand der Mörsergranate zu verschieben, so dass der sich auf der Führungskontur mit seinem ersten Ende abstützende Sperrstift aufgrund der sich ändernden Führungskontur aus der ersten Ausnehmung des Detonatorträgers herausgedrückt wird und der Detonatorträger in seine Zündposition schwenkbar ist. The essence of this invention is, according to design minimally invasive standards and with sufficient consideration of those fly-k-specific design features, or the functionally unchanged retention thereof, to implement here a second security device in this design. In this context, this invention is based on partially bypassing propellant charge gases passing through the bullet-side thrusting surface and guiding it in a controlled manner to the front side of a shearing collar bolt which is preferably now transversely and gas-tightly installed in the firing direction. Since in a regular launch of fly-k-grenades the pressure level of the launching gases corresponds to a multiple of the shearing force in the collar of this shear collar bolt, this is in connection with the already existing first safety device (g-switch with downstream escapement) ensures that peripheral forces here can lead to any irregular trigger detonation. The invention is therefore based essentially on the idea that the active partial igniter comprises a detonator carrier which can be pivoted from a secured position into an ignition position and which is operatively connected to a first securing device which, when used as intended, extends in the longitudinal direction of the corresponding mortar shell. comprises a spring loaded locking pin, which is supported with its first end to a shear pin. In this case, the shear pin is arranged within a transverse bore and has on its the first end of the locking pin side facing a guide contour, such that in the secured position of the Detonatorträgers the second end of the locking pin is pressed against the pressure of the spring in a recess of the Detonatorträgers and prevents a pivoting movement of the Detonatorträgers in its ignition position. The transverse bore has a connection bore through which the propellant charge gases can pass into the transverse bore when the mortar shell is fired and cause an increase in pressure sufficient to separate the part of the shear bolt provided with the guide contour from the remaining part of the shear bolt and along the transverse bore move in the direction of the outer wall of the mortar shell, so that the resting on the guide contour with its first end locking pin is pushed out of the first recess of the Detonatorträgers due to the changing guide contour and the Detonatorträger is pivotable into its firing position.
Im Gegensatz zu bekannten Wirkteilzündern von Mörsergranaten mit Kopfzünder schlägt die Erfindung also vor, nicht die äußere Luftströmung zur Betätigung der Sicherheitseinrichtung des Wirkteilzünders heranzuziehen, sondern die bei Abschuss heckseitig auf den Stoßboden der Mörsergranate wirkenden Treibladungsgase. In contrast to known active partial igniters of mortar shells with a head detonator, the invention therefore proposes not to use the external air flow for actuating the safety device of the active part igniter, but the propellant charge gases acting on the bottom of the mortar shell at the firing point.
Als besonders vorteilhaft hat es sich erwiesen, wenn der Scherbolzen als Scherkragenbolzen ausgebildet ist. It has proved to be particularly advantageous if the shear pin is designed as a shearing collar pin.
Bei einem bevorzugten Ausführungsbeispiel der Erfindung umfasst der erfindungsgemäße Wirkteilzünder zusätzlich zu der ersten Sicherungseinrichtung eine von der Abschussbeschleunigung der Mörsergranate abhängige zweite Sicherheitseinrichtung, die einen axial verschiebbaren Sicherungsbolzen aufweist, der in der Ruheposition der Mörsergranate mittels eines Rückstellelementes in eine zweite Ausnehmung des Detonatorzünders eingreift, und der bei Erreichen einer vorgegebenen Abschussbeschleunigung durch die Trägheitskräfte gegen den Druck des Rückstellelementes aus der zweiten Ausnehmung herausgedrückt wird. Bei einer erfindungsgemäßen aus einem Zapfenmörser verschießbaren Mörsergranate mit einem als Bodenzünder ausgebildeten Wirkteilzünder wird vorgeschlagen, dass der Scherbolzen innerhalb einer in dem Stoßboden der Mörsergranate befindlichen Querbohrung angeordnet ist, welche über die in dem Stoßboden axial angeordnete Verbindungsbohrung mit dem Treibrohr verbunden ist. In a preferred embodiment of the invention, the active part igniter according to the invention comprises in addition to the first safety device dependent on the mortar shell launching second safety device having an axially displaceable safety pin which engages in the rest position of the mortar shell by means of a return element in a second recess of the detonator igniter, and which is pressed upon reaching a predetermined launch acceleration by the inertial forces against the pressure of the return element of the second recess. In a mortar shell of the invention, which can be fired from a mortise mortiser, with a live igniter designed as a bottom igniter, it is proposed that the shearbolt be arranged within a transverse bore located in the bottom of the mortar shell, which is connected to the propellant tube via the connecting bore arranged axially in the thrust plate.
Allerdings kann auch vorgesehen werden, dass der Wirkteilzünder ein Zündergehäuse umfasst, welches in die Mörsergranate einsetzbar ist, und in dem sich sowohl die Querbohrung mit Scherbolzen als auch der Sperrstift befinden. However, it can also be provided that the active partial igniter comprises an igniter housing, which can be inserted into the mortar shell, and in which both the transverse bore with shear pins and the locking pin are located.

In den Fig.1 und 2 ist mit 1 eine aus einem Zapfenmörser verschießbare Mörsergranate bezeichnet, wobei allerdings lediglich die Mörsergranate im Bereich ihres mit 2 bezeichneten Stoßbodens dargestellt ist. In FIGS. 1 and 2, 1 designates a mortar shell which can be fired from a mortise mortar, although only the mortar shell is shown in the region of its collision surface designated by 2.
Die Mörsergranate 1 weist heckseitig ein als zugleich als Treibrohr 3 dienendes hohles Leitwerksteil auf, wobei das Treibrohr 3 nach oben hin (in Schussrichtung) durch den Stoßboden 2 begrenzt ist. Im Inneren 4 des Treibrohres 3 befindet sich der vordere Teil des Zapfens 5 eines nicht weiter dargestellten Zapfenmörsers. In diesem Zapfen 5 ist ein durch eine nicht dargestellte Abschussvorrichtung betätigbarer Schlagbolzen 30 eingelassen. An den Stoßboden 2 der Mörsergranate 1 schließt sich innerhalb des Treibrohres 3 eine Treibladung 6 an, die sich in einem zum heckseitigen Ende der Granate axial verschiebbarer Treibkolben 7 befindet. The mortar shell 1 has at the rear as at the same time serving as a driving tube 3 hollow tail part, wherein the driving tube 3 is bounded at the top (in the weft direction) by the impact bottom 2. Inside the 4 of the driving tube 3 is the front part of the pin 5 of a mortise not shown. In this pin 5 an actuatable by a launcher, not shown firing pin 30 is inserted. To the bottom 2 of the mortar pestle 1 is followed within the driving tube 3, a propellant charge 6, which is located in a rear end of the grenade axially displaceable driving piston 7.
Die Mörsergranate 1 umfasst einen als Bodenzünder ausgebildeten Wirkteilzünder 8 mit einem von einer gesicherten Position in eine Zündposition schwenkbaren Detonatorträger 9. The mortar shell 1 comprises an effective partial igniter 8 designed as a bottom igniter with a detonator carrier 9 which can be pivoted from a secured position into an ignition position.
Dieser Detonatorträger 9 steht mit einer erfindungsgemäßen ersten Sicherungseinrichtung 10 des Wirkteilzünders 8 in Wirkverbindung. Hierzu umfasst die erste Sicherungseinrichtung 10 einen sich in Richtung der Längsachse 100 der Mörsergranate 1 erstreckenden, durch eine Feder 1 1 entgegen der Schussrichtung belasteten Sperrstift 12. Dabei stützt sich der Sperrstift 12 mit seinem ersten Ende 13 an einem Scherkragenbolzen 14 ab (vgl. auch Fig.3). This detonator carrier 9 is in operative connection with a first securing device 10 according to the invention of the active part igniter 8. For this purpose, the first securing device 10 comprises a locking pin 12 which extends in the direction of the longitudinal axis 100 of the mortar shell 1 and is loaded by a spring 11 against the weft direction. The locking pin 12 is supported at its first end 13 on a shearing collar bolt 14 (cf. Figure 3).
Der Scherkragenbolzen 14 ist innerhalb einer Querbohrung 15 in dem Stoßboden 2 der Mörsergranate 1 angeordnet und wird hinsichtlich seines axialen Freiheitsgrades in der Querbohrung 15 durch den Scherkragen 31 des Scherkragenbolzens 14 positioniert. Der Scherkragenbolzen 14 weist auf seiner dem ersten Ende 13 des dem Sperrstift 12 zugewandten Seite eine Führungskontur 16 auf, derart, dass in der in den Fig.1 und 3 dargestellten gesicherten Position, bei welcher der auf dem Detonatorträger 9 befindliche Detonator (nicht dargestellt) außerhalb der Fluchtung einer Zündkette gehalten wird, das zweite Ende 17 des Sperrstiftes 12 gegen den Druck der Feder 1 1 in eine erste Ausnehmung 18 (Fig.2) des Detonatorträgers 9 formschlüssig gedrückt wird und eine Schwenkbewegung des Detonatorträgers 9 in seine Zündposition verhindert. The shear collar bolt 14 is disposed within a transverse bore 15 in the buttock 2 of the mortar shell 1 and is positioned in the transverse bore 15 with respect to its axial degree of freedom by the shear collar 31 of the shear collar bolt 14. The shearing collar pin 14 has on its the first end 13 of the locking pin 12 side facing a guide contour 16, such that in the illustrated in Figures 1 and 3 secured position in which the detonator 9 located on the detonator (not shown) is held outside the alignment of a detonating chain, the second end 17 of the locking pin 12 against the pressure of the spring 1 1 in a first recess 18 (Fig.2) of the Detonatorträgers 9 is positively pressed and prevents pivotal movement of the Detonatorträgers 9 in its ignition position.
Die Querbohrung 15 ist über eine in dem Stoßboden 2 axial angeordnete Verbindungsbohrung 19 mit dem Treibrohr 3 verbunden. The transverse bore 15 is connected via a in the joint bottom 2 axially arranged connecting bore 19 with the driving tube 3.
Zusätzlich zu der ersten Sicherungseinrichtung 10 ist eine zweite Sicherungseinrichtung 20 vorgesehen, welche in Abhängigkeit von der Abschussbeschleunigung der Mörsergranate 1 wirkt. Diese besteht im Wesentlichen aus einem in eine zweite Ausnehmung 21 des Detonatorträgers 9 eingreifenden Sicherungsbolzen 22, welcher durch ein elastisches Rückstellelement 23 beaufschlagt ist. Nachfolgend wird auf die Wirkungsweise der beiden Sicherungseinrichtungen 10 und 20 des Wirkteilzünders 8 beim Abschuss der erfindungsgemäßen Mörsergranate 1 eingegangen: In addition to the first securing device 10, a second securing device 20 is provided, which acts as a function of the firing acceleration of the mortar shell 1. This consists essentially of a engaging in a second recess 21 of the Detonatorträgers 9 securing bolt 22 which is acted upon by an elastic return element 23. Subsequently, the mode of action of the two safety devices 10 and 20 of the active part igniter 8 when firing the mortar shell 1 according to the invention will be discussed below:
Wie in Fig.1 angedeutet, befindet sich die Mörsergranate 1 auf dem Zapfen 5 des Mörsers (geladener Zustand des Mörsers). Trifft nun durch Betätigung einer entsprechenden Abschusseinrichtung (nicht dargestellt) der Schlagbolzen 30 auf den Treibladungsanzünder 24, so wird die Treibladung 6 gezündet, und der Treibkolben 7 wird durch die sich bildenden Treibladungsgase 25 mit hoher Kraft und Geschwindigkeit zum heckseitigen Ende der Mörsergranate 1 hinbewegt (Fig.2). Dabei wirkt der Treibkolben 7 auf den Zapfen 5 des Mörsers, so dass die Mörsergranate 1 in die Luft geschleudert wird. As indicated in Figure 1, the mortar shell 1 is on the pin 5 of the mortar (charged state of the mortar). If the firing pin 30 strikes the propellant charge igniter 24 by actuation of a corresponding firing device (not shown), the propellant charge 6 is ignited and the propellant piston 7 is moved by the propellant charge gases 25 with high force and velocity to the rear end of the mortar shell 1 ( Figure 2). In this case, the driving piston 7 acts on the pin 5 of the mortar, so that the mortar shell 1 is thrown into the air.
Nach Zündung der Treibladung 6 gelangt ein Teil bzw. eine dosierte Teilmenge der (expandierenden) Treibladungsgase 25 durch die Verbindungsbohrung 19 in die Querbohrung 15 und wirkt auf die Frontseite 32 des in der Querbohrung 15 durch den Scherkragen 31 fixierten Scherkragenbolzens 14 (Fig.3) und bewirkt dort eine Druckerhöhung. Die hieraus resultierende Druckkraft reicht aus, um ein Abscheren des Scherkragens 31 zu bewirken, so dass die axiale Lagefixierung des Scherkragenbolzens 14 aufgehoben wird. Der mit der Führungskontur 16 versehenen Teil 26 des Scherkragenbolzens 14 wird daher entlang der Querbohrung 15 in Richtung auf die Außenwand 27 der Mörsergranate 1 verschoben. Dadurch wird der sich auf der Führungskontur 16 mit seinem ersten Ende 13 abstützende und durch die Feder 1 1 vorgespannte Sperrstift 12 aufgrund der sich ändernden Führungskontur 16 aus der ersten Ausnehmung 18 des Detonatorträgers 9 herausgedrückt. D.h., nach Zündung der Treibladung 6 ergibt sich in der Querbohrung 15 eine Druckerhöhung, die ausreicht, um den mit der Führungskontur 16 versehenen Teil 26 des Scherkragenbolzens 14 von dem restlichen Teil des Scherkragenbolzen 14 abzutrennen und entlang der Querbohrung 15 in Richtung auf die Außenwand 27 der Mörsergranate 1 zu verschieben, sodass der sich auf der Führungskontur (16) mit seinem ersten Ende 13 abstützende Sperrstift 12 aufgrund der sich ändernden Führungskontur 16 aus der ersten Ausnehmung 18 des Detonatorträgers 9 herausgedrückt wird und der Detonatorträger 9 in seine Zündposition schwenkbar ist. After ignition of the propellant charge 6 enters a portion or a metered subset of the (expanding) propellant charge gases 25 through the connecting hole 19 in the transverse bore 15 and acts on the front side 32 of the transverse bore 15 through the shear collar 31 fixed shear collar bolt 14 (Figure 3). and causes a pressure increase there. The resulting compressive force is sufficient to cause a shearing of the shearing collar 31, so that the axial positional fixation of the shear collar pin 14 is released. The provided with the guide contour 16 portion 26 of the shear collar pin 14 is therefore displaced along the transverse bore 15 in the direction of the outer wall 27 of the mortar shell 1. As a result, the locking pin 12 supported on the guide contour 16 with its first end 13 and biased by the spring 11 is pressed out of the first recess 18 of the detonator carrier 9 due to the changing guide contour 16. That is, after ignition of the propellant charge 6 results in the transverse bore 15, a pressure increase sufficient to separate the provided with the guide contour 16 portion 26 of the shear collar pin 14 of the remaining part of the shear collar pin 14 and along the transverse bore 15 in the direction of the outer wall 27th to move the mortar shell 1, so that on the guide contour (16) with its first end 13 supporting locking pin 12 is pushed out of the first recess 18 of the Detonatorträgers 9 due to the changing guide contour 16 and the Detonatorträger 9 is pivotable in its firing position.
Außerdem wird durch die Beschleunigung der Mörsergranate 1 auch der Sicherungsbolzen 22 der zweiten Sicherungseinrichtung 20 gegen den Druck des Rückstellelementes 23 aus der zweiten Ausnehmung 21 herausgedrückt, so dass der Detonatorträger 9 mit- tels einer nicht dargestellten Drehfeder nun in seine Zündposition geschwenkt wird und damit der Detonator mit einer nicht dargestellten Anstichnadel einer Zündkette fluchtet. Moreover, as a result of the acceleration of the mortar shell 1, the securing bolt 22 of the second securing device 20 is pushed out of the second recess 21 against the pressure of the restoring element 23, so that the detonator carrier 9 Tels a torsion spring, not shown, is now pivoted to its ignition position and thus the detonator with a tapping needle, not shown, a Zündkette aligned.
Die Erfindung ist selbstverständlich nicht auf das beschriebene Ausführungsbeispiel beschränkt. So kann der erfindungsgemäße Wirkteilzünder nicht nur in Verbindung mit aus Zapfenmörsern verschießbaren Mörsergranaten verwendet werden, sondern er kann auch für Wirkteilzünder rohrgebundener Mörsergranaten eingesetzt werden. Allerdings ist für eine derartige Verwendung ebenfalls Voraussetzung, dass ein Teil des beim Abschuss der Mörsergranate gebildeten Treibladungsgases auf einen entsprechenden Scherbolzen des Wirkteilzünders wirken. The invention is of course not limited to the described embodiment. Thus, the active partial igniter according to the invention can not only be used in conjunction with mortar shells that can be fired from mortise mortars, but it can also be used for active partial igniters of mortar shells connected to tubular mortars. However, such a use is also a prerequisite that a part of the propellant charge gas formed during the firing of the mortar shell on a corresponding shear pin of the active part igniter act.
Die Erfindung ist zudem nicht auf die Verwendung eines Scherbolzens beschränkt. Auch so genannte Scherkragenbolzen können hierfür alternativ verwendet werden. The invention is also not limited to the use of a shear pin. Also so-called shear collar bolts can be used alternatively for this purpose.
