Description

Die Erfindung bezieht sich auf eine Splitterhülle eines Sekundärgeschosses eines Tandemgefechtskopfes nach dem Oberbegriff des Anspruches 1.The invention relates to a splinter shell of a secondary floor Tandem warhead according to the preamble of claim 1.

Entsprechend der US-A1 5,198 615 (siehe den Oberbegriff des Anspruchs 1) ist ein Tandemgefechtskopf mit einer kopfseitigen Hohlladung und einem nachgeordneten Sekundärgeschoß bekannt. Die Hohlladung hat die Aufgabe, in einer Deckung einer Durchschußkanal für das nachfolgende Sekundärgeschoß zu erzeugen. Nach dem Heraustreten des Sekundärgeschosses aus dem Durchschußkanal zerlegt sich das Sekundärgeschoß mit Splitterwirkung. Die Splitterwirkung wird durch die detonative Zerlegung der Geschoßhülle bewirkt.According to US-A1 5,198,615 (see the preamble of claim 1) is a tandem warhead with a head Hollow charge and a subordinate secondary storey known. The Hollow charge has the task of covering a bullet channel for the generate subsequent secondary storey. After stepping out of the secondary floor the secondary storey also breaks down from the bullet channel Splintering effect. The splintering effect is caused by the detonative dismantling of the shell causes.

Eine demgegenüber gesteigerte Splitterwirkung wird durch die DE-A1 39 41 445 erzeugt. Eine Infanteriegranate weist vorder- und rückseitig in ihren Ogiven vorgefertigte Splitter auf. Die Splitter sind an den Außenseiten der Ogiven angeordnet. Dadurch besteht keine Eignung als Sekundärgeschoß mit der Fähigkeit, einen Durchschußkanal unbeschädigt zu durchdringen, da die Gefahr besteht, daß beim Durchtritt durch den Durchschußkanal der Splittermantel zerstört wird. Andererseits würde der Splittermantel durch die Sprengstoffschwaden der vorgelagerten Hohlladung zerstört werden.In contrast, an increased splintering effect is described in DE-A1 39 41 445 generated. An infantry grenade has prefabricated front and back in their ogives Splinters on. The splinters are arranged on the outside of the ogives. As a result, there is no suitability as a secondary storey with the ability to Penetration channel to penetrate undamaged, since there is a risk that the Passing through the bullet channel, the splinter jacket is destroyed. On the other hand would the splinter coat through the explosive clouds of the upstream Hollow charge can be destroyed.

Die Aufgabe der Erfindung besteht darin, ein funktionssicheres Sekundärgeschoß eines Tandemgefechtskopfes mit gesteigerter Splitterwirkung vorzuschlagen, wobei das Sekundärgeschoß sowohl den Beanspruchungen nach Zündung der Hohlladung unbeeinflußt durch die Sprengstoffschwaden bleibt als auch den Beanspruchungen beim Durchtritt durch den Durchschußkanal stand hält. The object of the invention is to provide a functionally reliable secondary floor to propose a tandem warhead with increased splintering, whereby the secondary floor both the stresses after ignition of the shaped charge remains unaffected by the explosive swaths as well as the stresses withstands when passing through the bullet channel.

Die Aufgabe wird entsprechend den kennzeichnenden Merkmalen des Anspruches 1 gelöst.The task is in accordance with the characterizing features of the claim 1 solved.

Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen hervor.Advantageous developments of the invention emerge from the subclaims.

Erfindungsgemäß liegt ein sogenanntes gehärtetes Sekundärgeschoß vor; es werden daher keine, dem Sekundärgeschoß vorgelagerten, also separaten Schutzeinrichtungen gegen Sprengstoffschwaden der vorgelagerten Hohlladung benötigt. Andererseits ist die Splitterwirkung gegenüber dem Stand der Technik wesentlich gesteigert, da die Splitter spaltfrei an der Geschoßhülle, und zwar unter Vorspannung anliegen. Die gerundete Form der beiden Ogiven ergibt eine große Dichte der Splitter pro Raumwinkel bei hoher Splitterenergie. Beim Durchtritt des Sekundärgeschoß durch den Durchschußkanal ermöglicht die Form der vorderen Ogive ein problemloses Einfädeln in den Durchschußkanal bzw. zielseitigen Krater des Durchschußkanals. Die massive und gleichdicke Ogive gewährleistet auch, daß bei Hindernissen im Durchschußkanal, wie Reste von Armierungen, diese zur Seite hin verdrängt werden.According to the invention, there is a so-called hardened secondary floor; it will therefore no separate protective devices upstream of the secondary floor against explosives of the upstream shaped charge. On the other hand, the splintering effect is essential compared to the prior art increased, because the splinters on the projectile shell without gaps, and indeed under tension issue. The rounded shape of the two ogives results in a high density of Splinters per solid angle with high splinter energy. When passing through the secondary floor through the bullet channel the shape of the front ogive allows one problem-free threading into the bullet channel or target crater of the Bullet channel. The massive and equally thick ogive also ensures that at Obstacles in the bullet channel, such as remains of reinforcements, move them to the side to be ousted.

An embodiment of the invention is shown in the drawing. It shows:

Figure 2
an enlarged view of a secondary floor according to Figure 1 in longitudinal section.

Nach Figur 1 ist ein Sekundärgeschoß 1 in einem Rohrabschnitt 2 eines Gehäuses 3 eines Tandemgefechtskopfes 4 gelagert und über eine Gewindeverbindung 5 mit dem Gehäuse 3 verbunden. Ein Schwadenschutz ist mit 6 bezeichnet.According to Figure 1 is a secondary floor 1 in a pipe section 2 of a housing 3rd a tandem warhead 4 mounted and with a threaded connection 5 with connected to the housing 3. A steam protection is designated 6.

Der vordere Teil des Tandemgefechtskopfes 4 weist einen Abstandszünder 7 und eine Hohlladung 8 mit einem Zünder 9 auf.The front part of the tandem warhead 4 has a detonator 7 and a shaped charge 8 with an igniter 9.

Das Sekundärgeschoß 1 besteht aus zwei, über ein Gewinde 35 miteinander verschraubten Gehäuseteilen 10, 11. An den Gehäuseteilen 10, 11 sind Ogiven 44, 45 vorgesehen. Die Ogiven 44, 45 sind zueinander spiegelbildlich ausgebildet und bestehen bezüglich ihrer Außen- und Innenkontur aus insgesamt 4 Kreisbögen entsprechend den Radien 46 bis 49. Die Dicke der Ogiven ist in jedem Bogenabschnitt gleichdick, wobei ein zylindrischer Abschnitt 36 ebenfalls mit dieser Dicke versehen ist.The secondary floor 1 consists of two, screwed together via a thread 35 Housing parts 10, 11. On the housing parts 10, 11 there are ogives 44, 45 intended. The ogives 44, 45 are mirror images of one another and consist of a total of 4 arcs with regard to their outer and inner contours the radii 46 to 49. The thickness of the ogives is in each arc section equally thick, a cylindrical section 36 also being provided with this thickness is.

Beide Ogiven 44, 45 weisen an ihrer Innenwand 37, 38 jeweils eine Splitterladung 23, 24 aus vorgefertigten Splittern 39 auf. Die Splitterladung 24 erstreckt sich im hinteren Gehäuseteil 11 auch über den zylindrischen Abschnitt 36 und ist dort mit 24.1 bezeichnet.Both ogives 44, 45 each have a fragmentary charge on their inner wall 37, 38 23, 24 from prefabricated splinters 39. The fragmentary charge 24 extends in the rear housing part 11 also over the cylindrical portion 36 and is there with 24.1 designated.

Die Splitterladungen 23, 24 sind durch Stufen 65, 66 der Gehäuseteile 10, 11 begrenzt und durch Hüllen 67, 68 gegen, aus Sprengstoff bestehenden Wirkladungen 13, 14 abgedeckt.The fragment charges 23, 24 are limited by steps 65, 66 of the housing parts 10, 11 and by envelopes 67, 68 against explosive charges consisting of explosives 13, 14 covered.

Ein Zünder 20 trennt die beiden Wirkladungen 13, 14 voneinander, wobei der Zünder 20 durch die beiden Gehäuseteile 10, 11 bei 69 fest eingespannt ist.An igniter 20 separates the two active charges 13, 14, the Igniter 20 is firmly clamped at 69 by the two housing parts 10, 11.

Die Wirkladungen 13, 14 sind mit hohem Preßdruck gegen die Hüllen 67, 68 und die Splitterladungen 23, 24 innerhalb der Gehäuseteile 10, 11 gepreßt. Dadurch liegen die Splitter 39 spaltfrei an den Innenwänden 37, 38 der Gehäuseteile 10, 11 an, wobei die Hüllen 67, 68 im Bereich der Splitter 39 kalottenförmigen Einbuchtungen aufgrund des hohen Preßdruckes aufweisen. Damit besteht auch Spaltfreiheit zwischen den Wirkladungen 13, 14 und den Hüllen 67, 68 sowie zwischen den Hüllen 67 68 und den Splittern 39.The active charges 13, 14 are with high pressure against the sleeves 67, 68 and the fragmentary charges 23, 24 are pressed inside the housing parts 10, 11. Thereby the splinters 39 are gap-free on the inner walls 37, 38 of the housing parts 10, 11 on, the sleeves 67, 68 in the region of the splinters 39 dome-shaped indentations have due to the high pressure. This also means there is no gap between the active charges 13, 14 and the envelopes 67, 68 and between the Sleeves 67 68 and the splinters 39.

Bei Aufschlag des Tandemgefechtskopfes 4 auf eine nichtdargestellte, feindliche Deckung wird durch die Hohlladung 8 ein Krater mit anschließendem Durchschußkanal in der Deckung erzeugt. Durch den Krater und den Durchschußkanal dringt das vom Gehäuse 3 abgelöste Sekundärgeschoß mit seiner vorderen Ogive 44 ein. Eventuell auftretende Pendelungen mit damit verbundenem, schiefen Auftreffen des Sekundärgeschosses 1 in dem Krater des Durchschußkanales haben keinen nachteiligen Einfluß auf den Einfädelvorgang. Die Form der vorderen Ogive 44 ermöglicht in jedem Fall den Einfädelvorgang. Außerdem werden beim Durchgang des Sekundärgeschosses 1 durch den Durchschußkanal Wandberührungen abgefangen. Auch bewirkt die Ogivenform der Ogive 44, daß beim Berühren von Hindernissen im Durchschußkanal, wie Reste von Armierungen aus Stahl, verdrängt werden.When the tandem warhead 4 strikes an enemy enemy, not shown Coverage is through the hollow charge 8, a crater with subsequent bullet channel generated in the cover. Through the crater and the bullet canal penetrates the secondary floor detached from the housing 3 with its front ogive 44 a. Possibly occurring oscillations with the associated, oblique impact of the secondary floor 1 in the crater of the bullet canal no adverse influence on the threading process. The shape of the front ogive 44 enables threading in any case. Also, when going through of the secondary floor 1 through the bullet through wall contact intercepted. The ogive shape of the ogive 44 also means that when you touch Obstacles in the bullet channel, such as the remains of steel reinforcements, are displaced will.

Nach einer bestimmten Verzögerungszeit zündet der Zünder 20 gleichzeitig die Wirkladungen 13, 14. Damit wird erreicht, daß im unmittelbaren Bereich der Rückseite der feindlichen Deckung eine große Splitterwirkung erzielt wird. Insbesondere wird dies durch die hintere Wirkladung 14 erreicht, indem dort eine wesentlich größere Splitterladung 24, 24.1 vorgesehen ist als bei der vorderen Wirkladung 13.After a certain delay time, the igniter 20 simultaneously ignites the Active charges 13, 14. This ensures that in the immediate area A large splintering effect is achieved on the rear of the enemy cover. Especially this is achieved by the rear active charge 14, by making one essential larger fragment charge 24, 24.1 is provided than in the front Active charge 13.

Wesentlich für die Splitterrichtung und die Menge der Splitter pro Raumwinkel sind die Außen- und die Innenkontur der Ogiven 44, 45 aufgrund der durch Kreisbögen gebildeten Bogenabschnitte, siehe die Radien 46-49.Essential for the direction of the splinters and the amount of splinters per solid angle are the outer and inner contours of the ogives 44, 45 due to the use of arcs formed arc sections, see the radii 46-49.

Die Splitterwirkung setzt sich zusammen aus den Splittern der Gehäuseteile 10, 11 und aus den Splittern 39 der Splitterladungen 23, 24.The splitting effect is composed of the splinters of the housing parts 10, 11 and from the splinters 39 of the splinter charges 23, 24.

Versuche haben auch gezeigt, daß bei der Detonation der Hohlladung 8 die auf die Ogive 44 aufschlagenden Teile des Zünders 9 weder zu einer Beschädigung der Ogive 44 führt noch die Funktion der Wirkladungen 13, 14 inklusive des Zünders 20 beeinträchtigen. Denn aus der Konstruktion des Sekundärgeschosses 1 resultiert eine sogenannte ,,gehärtete" Bauweise. Aufgrund dieser Tatsache sind keinerlei zusätzliche Schutzvorrichtungen zur Abweisung von Sprengstoffschwaden zwischen dem Zünder 9 und dem Sekundärgeschoß 1 erforderlich. Vielmehr ist es möglich, das Sekundärgeschoß 1 unmittelbar hiter dem Zünder 9 über einen kurzen Abstand 83 anzuordnen.Experiments have also shown that the detonation of the shaped charge 8 on the Ogive 44 impacting parts of the igniter 9 neither damage the Ogive 44 still performs the function of the active charges 13, 14 including the detonator 20 affect. Because of the construction of the secondary floor 1 results a so-called "hardened" construction. Due to this fact, none additional protective devices for the rejection of explosive vapors between the detonator 9 and the secondary floor 1 required. Rather it is possible, the secondary floor 1 immediately hit the detonator 9 over a short To arrange distance 83.

Einen großen Anteil an der Unempfindlichkeit des Sekundärgeschosses 1 hat die spezielle eiförmige Form der Ogive 44. Sie erfüllt eine vierfache Funktion:

  • 1. Sprengstoffschwaden der Hohlladung 8 und Teile des Zünders 9 werden bei der Detonation der Hohlladung 8 abgewiesen.
  • 2. Die Form der Ogive gewährleistet den Einfädelvorgang in den Krater des Durchschußkanals.
  • 3. Die Ogivenform stabilisiert den Durchgang des Sekundärgeschosses 1 durch den Durchschußkanal, wobei eventuelle Hindernisse seitlich abgedrängt werden.
  • 4. Es liegt eine optimierte Splitterleistung insbesondere der hinteren Wirkladung 14 vor.
    • The special egg-shaped shape of the ogive 44 plays a large part in the insensitivity of the secondary storey 1. It fulfills a fourfold function:
  • 1. Explosive swaths of shaped charge 8 and parts of detonator 9 are rejected when the shaped charge 8 is detonated.
  • 2. The shape of the ogive ensures the threading process into the crater of the bullet channel.
  • 3. The ogive shape stabilizes the passage of the secondary storey 1 through the bullet channel, any obstacles being pushed aside.
  • 4. There is an optimized fragmentation performance, in particular of the rear active charge 14.

    • Bei einem nicht koaxialen Austritt aus dem Durchschußkanal, also bei einer Schräglage oder bei einer Querlage des Sekundärgeschosses 1 ist die Splitterleistung der hinteren Wirkladung 14 nur noch zum Teil in Richtung auf die durchschlagene Wand der Deckung wirksam. Aufgrund der beiden eiförmigen Ogiven 43, 44 und des nahezu durchgängigen Sprengstoffs über die gesamte Geschoßlänge des Sekundärgeschosses - also insbesondere über nahezu die gesamte Zünderlänge - treten zu der nur zum Teil wirksamen Splitterleistung der hinteren Wirkladung 14 Splitteranteile der Gehäuseabschnitte 10, 11, nämlich der Abschnitt 74 zwischen den Splitterladungen 23 und 24 und ein anschließender Abschnitt 64 der vorderen Splitterladung 23 plus Gehäuseanteil. Es gibt also nur einen schmalen Splitterbereich 75 aufgrund des Bundes 70 des Zünders 20 mit reduziertern Splitteranzahl. Aus diesem Bereich 75, der keinen Sprengstoff aufweist, resultiert aufgrund der benachbarten Sprengstoffmengen 13.1, 14.1 ein Splitterbereich 76 mit geringerer Splitterdichte.In the event of a non-coaxial exit from the through-channel, that is to say with a Oblique position or with a transverse position of the secondary storey 1 is the fragmentation power the rear active cargo 14 only partially in the direction of the penetrated Wall of cover effective. Because of the two egg-shaped ogives 43, 44 and the almost continuous explosives over the entire length of the storey of the secondary storey - in particular over almost the entire length of the detonator - occur to the only partially effective fragmentation performance of the rear active cargo 14 fragments of the housing sections 10, 11, namely the section 74 between the fragmentary charges 23 and 24 and a subsequent section 64 of the front Splinter charge 23 plus housing part. So there is only a small fragment area 75 due to the bundle 70 of the detonator 20 with a reduced number of fragments. This area 75, which has no explosives, results from the adjacent explosive quantities 13.1, 14.1 a fragment area 76 with a smaller one Splinter density.

    Die Unempfindlichkeit des Zünders 20 bei Detonation der Hohlladung 8 und auch bei Aufschlag des Sekundärgeschosses 1 in den Krater des Durchschußkanales und schließlich die Erschütterungen beim Durchgang des Sekundärgeschosses 1 durch den Durchschußkanal beruht auf der einseitigen bzw. "fliegenden" Lagerung bzw. Befestigung des Zünders 20 in dem Sekundärgeschoß 1. Der Bund 70 stellt die einzige Befestigungstelle für den Zünder 20 in Verbindung zu den Gehäuseteilen 10, 11 dar. In Achsrichtung des Sekundärgeschosses 1 bestehen nur schmale Auflageflächen aufgrund der Bunde 72, 73 der Gehäuseteile 10, 11. Das bedeutet, daß Stoßwellen aufgrund der Detonation der Hohlladung 8 als auch Erschütterungen beim Aufschlag in den Krater des Durchschußkanales bzw. Erschütterungen beim Durchgang des Sekundärgeschosses 1 durch den Durchschußkanal in einem nur sehr geringem Maße auf den Zünder 20 übertragen werden. Dadurch treten keinerlei Zünderstörungen auf und es ist eine präzise Funktion des Zünders 20 gerade im Hinblick auf den richtigen Zeitpunkt der Zündung auf der Rückseite der Deckung sichergestellt.The insensitivity of the igniter 20 upon detonation of the shaped charge 8 and also when the secondary storey 1 hits the crater of the bullet canal and finally the vibrations when passing through the secondary floor 1 the bullet channel is based on the one-sided or "flying" storage or Attachment of the igniter 20 in the secondary floor 1. The collar 70 provides the only attachment point for the igniter 20 in connection with the housing parts 10, 11. In the axial direction of the secondary floor 1 there are only narrow contact surfaces due to the bundles 72, 73 of the housing parts 10, 11. This means that Shock waves due to the detonation of the shaped charge 8 as well as vibrations when it hits the crater of the bullet canal or shocks when Passage of the secondary floor 1 through the bullet channel in one only are transmitted to the igniter 20 to a very small extent. This does not result in any kick Detonator malfunctions and it is a precise function of the igniter 20 just in With regard to the right time of ignition on the back of the cover ensured.

    Der bereits beschriebene Effekt der speziellen Zünderlagerung des Zünders 20 in dem Sekundärgeschoß 1 beruht in geometrischer Hinsicht auf der kurzen Einspannlänge des Bundes 70 von etwa 5 bis 10 % der Gesamtlänge 77 des Zünders 20, was kaliberabhängig ist. Bei einem Kaliber von 47 mm beträgt die Einspannlänge des Bundes 70 ca. 6 %.The effect of the special igniter mounting of the igniter 20 in already described The secondary storey 1 is based on the short clamping length in geometric terms of the federal government 70 from about 5 to 10% of the total length 77 of the igniter 20, what is caliber dependent. With a caliber of 47 mm, the clamping length is of the federal government 70 approx. 6%.

    Der Durchmesser 78 des Sekundärgeschosses 1 beträgt etwa 33 bis 40 % der Gesamtlänge 79, wobei bei dem vorgenannten Kaliber 37 % vorliegen. Dieses Verhältnis gewährleistet ein sehr gutes Freiflugverhalten, das ab dem Ablösen des Sekundärgeschosses 1 vom Rohrabschnitt 2 des Tandemgefechtskopfes 4 beginnt, jedoch unterbrochen ist während des Durchgangs durch den Durchschußkanal einer Deckung und mit einer minimalen Wegstrecke auf der Rückseite der Deckung durch Zündung des Sekundärgeschosses 1 endet.The diameter 78 of the secondary storey 1 is approximately 33 to 40% of the total length 79, with the aforementioned caliber being 37%. That relationship guarantees a very good free flight behavior, that from detachment of the secondary floor 1 starts from the tube section 2 of the tandem warhead 4, however, one is interrupted during passage through the bullet channel Cover and with a minimal distance on the back of the cover by igniting the secondary floor 1 ends.

    Ein Optimum an Splitterdichte und Splitterenergie ist durch die Länge der Ogive 44, 45 in bezug auf den Durchmesser 78 des Sekundärgeschosses 1 gegeben. Dieses Verhältnis beträgt etwa 65 bis 75 %, wobei bei dem genannten Kaliber 70 % vorliegen.An optimal splinter density and splinter energy is due to the length of the ogive 44, 45 given in relation to the diameter 78 of the secondary floor 1. This Ratio is about 65 to 75%, with the caliber mentioned 70% available.

    Die Splitterleistung des Sekundärgeschosses setzt sich aus den vorgefertigten Splittern 39 und den Splittern aus den Gehäuseteilen 10, 11 zusammen. Hierbei ist die Dicke 82 der vorgefertigten Splitter 39 in Sprengrichtung etwa 4,5 bis 5 % (im Falle des Kalibers von 47 mm 4,7 %) und die Dicke 81 der Ogive 44, 45 in Sprengrichtung (Dicke der Splitter) etwa 7 bis 8,5 % des Durchmessers 78 des Sekundärgeschosses 1 (kaliberbezogen 7,8 %).The fragmentation performance of the secondary storey is made up of the prefabricated ones Splinter 39 and the splinters from the housing parts 10, 11 together. Here is the thickness 82 of the prefabricated splinters 39 in the direction of the blast approximately 4.5 to 5% (in Case of the caliber of 47 mm 4.7%) and the thickness 81 of the ogive 44, 45 in Blasting direction (thickness of the splinters) about 7 to 8.5% of the diameter 78 of the Secondary level 1 (caliber-related 7.8%).

    Die vorbeschriebenen Funktionen des Sekundärgeschosses 1 erfordern einen hochbeanspruchbaren Werkstoff und werden durch einen, mit Molybdän legierten Chrom-Nickelstahl gewährleistet.The above-described functions of the secondary floor 1 require a heavy-duty Material and are made of an alloyed with molybdenum Chrome-nickel steel ensures.
