The plastic material is a sleeve, and is unfolded inside the projectile, so that it rests against the inner wall. Explosive material is then supplied via the opening, after which the opening is sealed.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines großkalibrigen Sprenggeschosses mit einer Geschoßhülle, die einen mit einer kunststoffgebundenen Sprengladung gefüllten Innenraum umschließt und ein spitzenseitig verschließbares Mundloch aufweist, über welches die Sprengladung in den Innenraum des Sprenggeschosses eingebracht wird. Die Erfindung bezieht sich ferner auf ein Sprenggeschoß, welches nach diesem Verfahren hergestellt ist.The invention relates to a method for producing a large-caliber explosive projectile with a projectile casing, which encloses a filled with a plastic-bonded explosive charge interior and has a tip-side closable mouth hole through which the explosive charge is introduced into the interior of the explosive projectile. The invention further relates to an explosive projectile produced by this process.

In vielen Fällen wird in der Wehrtechnik die Verarbeitung insensitiver Sprengladungen gefordert. Dabei handelt es sich in der Regel um kunststoffgebundene Sprengladungen, die trotz einer hohen Wirkleistung eine relativ hohe Unempfindlichkeit aufweisen. Kunststoffgebundene Sprengladungen weisen allerdings den Nachteil auf, daß sie einen relativ großen Wärmeausdehnungskoeffizienten besitzen, der acht bis zwölfmal größer ist, wie etwa derjenige einer aus Stahl bestehenden Geschoßhülle eines entsprechenden Sprenggeschosses. In einem derartigen mit Sprengstoff gefüllten Geschoß treten bei positiven Temperaturen Spannungen auf, so daß der Sprengstoffkörper in der Geschoßhülle gehalten wird, während sich der Sprengstoffkörper bei niedrigeren Temperaturen zusammenzieht und dann lose in der Geschoßhülle liegt.In many cases, defense technology demands the processing of insensitive explosive charges. These are usually plastic-bound explosive charges, the despite a high active power have a relatively high insensitivity. Bonded However, explosive charges have the disadvantage that they have a relatively large Have thermal expansion coefficient, which is eight to twelve times greater, such as that of a projectile steel shell of a corresponding explosive projectile. In such an explosive-filled projectile occur at positive temperatures Tensions so that the explosives body is held in the projectile casing, while the explosive body contracts at lower temperatures and then loose in the projectile casing.

Ein derartiges Sprenggeschoß mit einer kunststoffgebundenen Sprengladung und den vorstehend beschriebenen Nachteilen ist beispielsweise aus der DE 196 48 355 A1 bekannt. Such an explosive projectile with a plastic-bound explosive charge and the disadvantages described above is known for example from DE 196 48 355 A1.

Aus der US 2,373.883 ist ein großkalibriges Sprenggeschoß mit einer Geschoßhülle bekannt, die einen mit einer Sprengladung gefüllten Innenraum umschließt. An den Innenwänden des Innenraumes ist eine sackförmig ausgebildete Gummihülle angeordnet, in welche die Sprengladung durch eine vorderseitige Geschoßöffnung eingebracht werden kann. Nach dem Einbringen der Sprengladung wird die vorderseitige Öffnung seitlich zugedrückt, wobei ein als Zündladung benötigter Sprengstoffanteil in einer Ausnehmung verbleibt. Das Ende der Gummihülle wird außenseitig an der Geschoßspitze angeordnet, derart, daß die Hülle beim Flug des Geschosses etwas zur Geschoßspitze hin verschoben wird und dabei die Zündladung in den außenseitigen Geschoßspitzenbereich gelangt.From US 2,373,883 is a large caliber explosive projectile with a projectile shell known, which encloses a filled with an explosive charge interior. To the Interior walls of the interior is arranged a bag-shaped rubber sheath, in which the explosive charge is introduced through a front-side projectile opening can be. After the introduction of the explosive charge, the front side Pressed opening laterally, with a required explosive charge as explosive charge remains in a recess. The end of the rubber cover is on the outside of the Projectile tip arranged such that the envelope during flight of the projectile something to Projectile tip is shifted towards while the ignition charge in the outside Projectile tip area passes.

Aus der US 4,365,556 ist es bekannt, daß bei Sprengladungen, die durch Gießen in eine Geschoßhülle eingebracht werden, aufgrund von Schrumpfungsvorgängen zwischen der heckseitigen Basisfläche der Geschoßhülle und der angrenzenden erstarrten Sprengladung eine Beabstandung erfolgen kann. Um diese Beabstandung zwischen der Geschoßhülle und der Sprengladung zu minimieren, wird in dieser Druckschrift die Verwendung einer elastischen Ausgleichsscheibe vorgeschlagen, die durch ein den Kopfzünder aufnehmendes Adapterteil zusammengedrückt wird, so daß die Sprengladung unter Vorspannung steht.From US 4,365,556 it is known that in explosive charges by casting in a projectile casing are introduced due to shrinking operations between the rear base surface of the projectile shell and the adjacent solidified Explosive charge can be made a spacing. To this spacing between to minimize the projectile shell and the explosive charge, is in this document the use of an elastic shim proposed by a head part receiving the adapter part is compressed, so that the Explosive charge is under bias.

Aus der GB 1 439 450 ist ein Verfahren zum Zusammenpressen einer pulverförmigen Sprengladung bekannt, die durch ein relativ kleines, spitzenseitig verschließbares Mundloch einer Geschoßhülle in den Innenraum des Sprenggeschosses eingefüllt wird. Hierzu wird nach dem Einbringen der Sprengladung eine elastische Hülle in den Innenraum des Sprenggeschosses eingebracht und mit einem Druckmedium gefüllt, so daß die sich ausdehnende Hülle die Sprengladung zusammenpreßt.From GB 1 439 450 a method for compressing a powdery one is known Explosive charge known by a relatively small, lace-side closable Mouth hole of a projectile shell filled in the interior of the explosive projectile becomes. For this purpose, after the introduction of the explosive charge an elastic sheath in introduced the interior of the explosive projectile and filled with a pressure medium, so that the expanding envelope compresses the explosive charge.

Aus der GB 1 212 116 ist es bekannt, als Kunststoffhülle eine Dachfolie zu verwenden, welche in Richtung der Längsachse des Sprenggeschosses sich erstreckende dachför-mige Ausstülpungen aufweist, um nach Zündung des Geschosses auf einfache Weise vorgeformte Splitter zu erzeugen.From GB 1 212 116 it is known to use a plastic film as a roof foil, which extending in the direction of the longitudinal axis of the explosive projectile has roof-shaped protuberances to after ignition of the projectile to simple How to create preformed fragments.

Schließlich ist aus der DE 3 929 020 A1 ein Sprenggeschoß mit einem Kopfzünder bekannt, welcher auf der der Sprengladung zugewandten Seite eine Hohlladung aufweist, die über eine freie Wegstrecke innerhalb eines Leitrohres einen Anfeuerungssatz initiiert, welcher dann seinerseits die Sprengladung zündet.Finally, from DE 3 929 020 A1 an explosive projectile with a head detonator known, which has a shaped charge on the side facing the explosive charge, the over a free path within a guide tube Anfeuerungssatz initiated, which in turn ignites the explosive charge.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung eines großkalibrigen Sprenggeschosses anzugeben, bei dem auch bei Verwendung kunststoffgebundener Sprengladungen der Sprengstoffkörper selbst bei großen Temperaturschwankungen immer unter Vorspannung in der Geschoßhülle gehalten wird.The invention is based on the object, a method for producing a großkalibrigen Specify explosive bullet, in which even when using plastic-bound Explosive charges of the explosive bodies always with large temperature fluctuations held under bias in the projectile casing.

Diese Aufgabe wird erfindungsgemäß hinsichtlich des Verfahrens durch die Merkmale des Anspruchs 1 und hinsichtlich des Sprenggeschosses durch die Merkmale des Anspruchs 9 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved according to the invention by the features of the Claim 1 and with regard to the explosive projectile by the features of claim 9 solved. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, die Sprengladung in einer Kunststoffhülle aus einem elastischen Material in dem Sprenggeschoß anzuordnen, so daß bei Temperaturschwankungen das sich ändernde Volumen der Sprengladung durch die elastische Kunststoffhülle aufgenommen wird. Da bei großkalibrigen drallstabilisierten Artilleriegeschossen die entsprechende Sprengladung in der Regel lediglich über ein vorderes kleines Mundloch (Kopfzünderaufnahme) eingefüllt werden kann, ist es nicht möglich, bereits in Kunststoff-Folien verpackte Sprengladungen in den Innenraum eines derartigen Sprenggeschosses einzubringen. Die Erfindung schlägt daher vor, durch das Mundloch zunächst nur eine zusammengefaltete oder zusammengepreßte, sackförmig ausgebildete Kunststoffhülle in den Innenraum des Sprenggeschosses einzubringen, deren Abmessungen im entfalteten Zustand im wesentlichen den Abmessungen des Innenraumes des Sprenggeschosses entspricht. Anschließend wird dann die Kunststoffhülle z.B. durch Aufblasen oder aufgrund ihrer elastischen Rückstellkräfte entfaltet, so daß sie an den Innenwänden des Innenraumes des Sprenggeschosses formschlüssig anliegt. Dann wird die gießfähige kunststoffgebundene Sprengladung ebenfalls durch das Mundloch in die Kunststoffhülle eingebracht. Nach dem Auspolymerisieren des kunststoffgebundenen Sprengstoffes wird das Mundloch z.B. durch Einschrauben eines Kopfzünders verschlossen.The invention is based essentially on the idea of the explosive charge in one To arrange plastic envelope of an elastic material in the explosive projectile, so that in the case of temperature fluctuations, the changing volume of the explosive charge by the elastic Plastic sleeve is added. As with large-caliber spin-stabilized artillery shells the corresponding explosive charge usually only over a front small mouth hole (head fuse holder) can be filled, it is not possible already packed in plastic films explosive charges in the interior of such To bring in explosive projectile. The invention therefore proposes, through the mouth hole first only a folded or compressed, bag-shaped To bring plastic envelope into the interior of the explosive projectile whose dimensions in the unfolded state substantially the dimensions of the interior of the Explosive projectile corresponds. Subsequently, the plastic wrap is then e.g. by inflating or unfolded due to their elastic return forces, so that they on the inner walls the interior of the explosive projectile rests positively. Then the pourable plastic-bound explosive charge also through the mouth hole in the plastic cover brought in. After polymerizing the plastic-bound explosive if the mouth hole becomes e.g. closed by screwing in a detonator.

Um zu erreichen, daß selbst bei großen Temperaturschwankungen der Sprengstoffkörper unter Vorspannung in der Geschoßhülle gehalten werden kann, hat es sich als zweckmäßig erwiesen, zusätzliche Spannmittel vorzusehen, die das sich gegenüber der Geschoßhülle ändernde Volumen der Sprengladung ausgleichen. In order to achieve that even with large temperature fluctuations of the explosives body under bias in the projectile casing, it has to be useful proved to provide additional clamping means, which is opposite to the projectile casing compensate for changing volumes of the explosive charge.

Dabei hat es sich als vorteilhaft erwiesen, wenn vor dem Verschließen des Mundloches eine elastische Ausgleichsscheibe auf der Sprengladung angeordnet wird, die beim Einschrauben des Kopfzünders oder eines mit dem Kopfzünder verbundenen Adapterteiles durch diese Teile etwas zusammengepreßt wird, so daß die Sprengladung ständig unter Vorspannung steht.It has proved to be advantageous if, before closing the mouth hole an elastic shim is placed on the explosive charge when screwing the head igniter or an adapter part connected to the head igniter something is compressed by these parts, so that the explosive charge constantly under Preload is.

Um bei drallstabilisierten Sprenggeschossen eine gute Drallübertragung zwischen der Geschoßhülle und der Sprengladung sicherzustellen, kann die Kunststoffhülle mit der Innenwand des Innenraumes des Sprenggeschosses mindestens in Teilbereichen verklebt werden. Außerdem kann die Drallübertragung von der Geschoßhülle auf den Sprengstoff dadurch gefördert werden, daß die Wände des Innenraumes mindestens in einem bodenseitigen Teilbereich eine mehreckige Ausgestaltung aufweisen.In spin stabilized explosive projectiles a good swirl transmission between the Projectile shell and the explosive charge can ensure the plastic shell with the Inner wall of the interior of the explosive projectile adhered at least in some areas become. In addition, the twist transmission from the projectile casing on the Explosives are promoted by the fact that the walls of the interior at least in a bottom-side portion have a polygonal configuration.

Allerdings haben Versuche der Anmelderin ergeben, daß beim Abschuß des erfindungsgemäßen Sprenggeschosses auch ohne besondere Maßnahmen eine gute Drallübertragung zwischen der Geschoßhülle und einer kunststoffgebundenen Sprengladung erfolgt, weil die Sprengstoffmasse sich beim Abschuß aufgrund des Kunststoffanteiles verformt und sich zusammen mit der Kunststoffhülle in der Geschoßhülle "festsetzt".However, attempts by the Applicant have shown that when firing the inventive Explosive projectile even without special measures a good spin transmission between the projectile casing and a plastic-bound explosive charge takes place because the explosive mass at the launch due to the plastic content deformed and "stuck" together with the plastic shell in the projectile shell.

Bei der Kunststoffhülle kann es sich sowohl um eine glatte Folie als auch um eine Dachfolie handeln, mit welcher nach der Detonation der Sprengladung vorgeformte Splitter erzeugt werden können. Hierzu sind ringförmige Abschnitte mit in Richtung der Längsachse des Sprenggeschosses sich erstreckenden dachförmigen Ausstülpungen vorgesehen, wobei die dachförmigen Ausstülpungen benachbarter ringförmiger Abschnitte jeweils um ein halbes Dach zueinander versetzt angeordnet sind.The plastic cover can be both a smooth film as well as a Dachfolie act, with which preformed after detonation of the explosive charge Splinters can be generated. For this purpose, annular portions are in the direction of Longitudinal axis of the projectile extending roof-shaped protuberances provided, wherein the roof-shaped protuberances of adjacent annular portions each offset by half a roof to each other.

Um ein schnelles und sicheres Durchzünden der Sprengladung zu gewährleisten, hat es sich als vorteilhaft erwiesen, wenn dem Zünder eine Verstärkerladung nachgeschaltet ist, die auf der der Sprengladung zugewandten Seite die Kontur einer Hohlladungseinlage besitzt, und wenn die Ausgleichsscheibe eine sich axial erstreckende zentrale Ausnehmung aufweist, so daß der nach dem Zünden der Verstärkerladung entstehende Hohlladungsstrahl ungehindert in die Sprengladung gelangt. Dabei kann es sich bei der Kontur der Hohlladungseinlage sowohl um eine Flach- wie um eine Spitzkegeleinlage handeln.To ensure a quick and safe ignition of the explosive charge, it has proved to be advantageous when the igniter followed by an amplifier charge is, on the explosive charge side facing the contour of a shaped charge liner has, and if the shim has an axially extending central recess has, so that the resulting after the ignition of the booster charge Hollow charge jet passes unhindered into the explosive charge. It may be in the Contour of the shaped charge liner around both a flat and a pointed cone insert act.

Um den Durchzündvorgang weiter zu beschleunigen, ist bei einer weiteren Ausführungsform der Erfindung vorgesehen, daß sich an die zentrale Ausnehmung der Ausgleichsscheibe ein Anzündrohr axial in die Sprengladung hinein erstreckt, an dessen der Ausgleichsscheibe abgewandten Ende ein Anfeuerungssatz angeordnet ist.In order to further accelerate the Durchzündvorgang is in another embodiment the invention provided that to the central recess of the shim an ignition tube extends axially into the explosive charge into which the Balancing disc facing away from a firing kit is arranged.

  • In Fig.1 ist mit 1 ein großkalibriges drallstabilisiertes Sprenggeschoß bezeichnet, wie es beispielsweise aus einer Panzerhaubitze verschossen werden kann. Das Sprenggeschoß 1 umfaßt eine Geschoßhülle 2 mit einem Bodenteil 3 und einem vorderseitigen Kopfzünder 4. Der Kopfzünder 4 ist in ein Adapterteil 17 eingeschraubt, welches seinerseits in ein Mundloch 5 der Geschoßhülle 2 eingeschraubt ist.In FIG. 1, 1 designates a large-caliber spin-stabilized explosive projectile, as it does For example, from a tank howitzer can be fired. The explosive projectile 1 comprises a projectile casing 2 with a bottom part 3 and a front-side head igniter 4. The head igniter 4 is screwed into an adapter part 17, which in turn is screwed into a mouth hole 5 of the projectile casing 2.

    Die Geschoßhülle 2 umgibt einen Innenraum 6, mit dessen Innenwänden 7 eine sackförmig ausgebildete elastische (gummiartige) Kunststoffhülle 8 verklebt ist, in welcher sich eine kunststoffgebundene Sprengladung 9 befindet. Die Kunststoffhülle 8 weist dabei eine glatte Oberfläche auf. Die Wanddicke der Kunststoffhülle 8 liegt vorteilhafterweise zwischen 0,3 und 0,6 mm. Außerdem hat es sich als vorteilhaft erwiesen, wenn als Material für die Kunststoffhülle 8 ein Kunststoff mit ca. 30% Gummianteil verwendet wird.The projectile casing 2 surrounds an interior 6, with its inner walls 7 a bag-shaped formed elastic (rubbery) plastic sheath 8 is glued, in which there is a plastic-bound explosive charge 9. The plastic shell 8 has doing a smooth surface. The wall thickness of the plastic sheath 8 is advantageously between 0.3 and 0.6 mm. In addition, it has proved to be advantageous if used as a material for the plastic sleeve 8, a plastic with about 30% rubber content becomes.

    Im bodenteilseitigen Bereich 10 des Sprenggeschosses 1 weisen die Geschoßhülle 2 und die Kunststoffhülle 8 zur Sicherstellung einer guten Drallübertragung von der Geschoßhülle 2 auf die Sprengladung 9 eine mehreckige Ausgestaltung auf (Fig.2).In the bottom part-side region 10 of the projectile 1, the projectile casing 2 and the plastic cover 8 to ensure a good spin transfer from the projectile shell 2 on the explosive charge 9 a polygonal configuration (Fig.2).

    Vorderseitig ist die Sprengladung 9 durch eine elastische Ausgleichsscheibe 11 abgeschlossen, auf deren der Sprengladung 9 abgewandten Seite das Adapterteil 17 einen vorgebbaren Druck ausübt, so daß die Sprengladung 9 unter Vorspannung steht.Front side, the explosive charge 9 is completed by an elastic shim 11, on which the explosive charge 9 side facing away from the adapter part 17 a applies predetermined pressure, so that the explosive charge 9 is under bias.

    Der Kopfzünder 4 ragt heckseitig in das Adapterteil 17, welches eine Verstärkerladung 12 umfaßt, die auf der der Sprengladung 9 zugewandten Seite die Kontur einer Hohlladungseinlage 13 aufweist. Außerdem besitzt die Ausgleichsscheibe 11 eine sich axial erstreckende Ausnehmung 14, so daß nach dem Zünden der Verstärkerladung 12 der entstehende Hohlladungsstrahl durch diese Ausnehmung 14 in die Sprengladung 9 gelangt und diese Ladung anzündet.The head igniter 4 protrudes into the rear of the adapter part 17, which is an amplifier charge 12 includes, on the explosive charge 9 side facing the contour of a shaped charge liner 13 has. In addition, the shim 11 has an axially extending recess 14, so that after the ignition of the booster charge 12 of resulting shaped charge jet passes through this recess 14 in the explosive charge 9 and ignite this charge.

    Zum Einlaborieren der Sprengladung 9 in das Sprenggeschoß 1 wird bei Bedarf zunächst Kleber auf die Innenwände 7 der Geschoßhülle 2 aufgebracht. Anschließend wird die Kunststoffhülle 8 derart zusammengedrückt, daß sie sich durch das Mundloch 5 in den Innenraum 6 schieben läßt. In dem Innenraum 6 geht die Kunststoffhülle 8 aufgrund der inneren Spannungen von selbst wieder auf und legt sich an die Innenwände 7 der Geschoßhülle 2 an. Daraufhin kann die Sprengladung 9 in die Kunststoffhülle 8 eingebracht und die elastische Ausgleichsscheibe 11 auf der Sprengladung 9 angeordnet werden. Abschließend wird dann zunächst das Adapterteil 17 in das Mundloch 5 eingeschraubt und anschließend der Kopfzünder 4 mit dem Adapterteil 17 verbunden.To work the explosive charge 9 into the explosive projectile 1, if necessary, first Glue applied to the inner walls 7 of the projectile casing 2. Subsequently the plastic sleeve 8 is compressed so that it passes through the mouth hole 5 can slide into the interior 6. In the interior 6, the plastic shell 8 goes due the internal stresses again on and lies down against the inner walls. 7 the projectile casing 2 on. Then the explosive charge 9 in the plastic sleeve. 8 introduced and the elastic shim 11 is disposed on the explosive charge 9 become. Finally, first the adapter part 17 is screwed into the mouth hole 5 and then the head igniter 4 is connected to the adapter part 17.

    Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. Wie aus dem in Fig.3 dargestellten Sprenggeschoß 1' entnehmbar ist, braucht die dort mit 11' gekennzeichnete elastische Ausgleichsscheibe sich nicht über den gesamten Querschnitt des Innenraumes 6' der Geschoßhülle 2' erstrekken. Das Adapterteil 17' befindet sich in diesem Fall vollständig innerhalb der Geschoßhülle 2'und der Kopfzünder 4' ist direkt in das Mundloch 5' eingeschraubt.Of course, the invention is not limited to the embodiment described above limited. As can be seen from the explosive projectile 1 'shown in FIG is, needs there 11 'marked elastic shim itself do not extend over the entire cross section of the inner space 6 'of the projectile casing 2'. The adapter part 17 'is in this case completely within the projectile casing 2 'and the head igniter 4' is screwed directly into the mouth hole 5 '.

    Außerdem kann zur schnellen und gleichmäßigen Anzündung der Sprengladung 9' ein Anzündrohr 15 vorgesehen sein, welches sich an die Ausnehmung 14' der Ausgleichsscheibe 11' anschließt und sich axial in die Sprengladung 9' hinein erstreckt. An dem der Ausgleichsscheibe 11' abgewandten Ende weist das Anzündrohr 15 einen Anfeuerungssatz 16 auf.In addition, for rapid and uniform ignition of the explosive charge 9 'a Ignition tube 15 may be provided, which is to the recess 14 'of the shim 11 'connects and extends axially into the explosive charge 9' into it. To the the shim 11 'facing away from the igniter tube 15 has a Anfeuerungssatz 16 on.

    Sofern bei der Detonation des Sprenggeschosses auf einfache Weise vorgeformte Splitter erzeugt werden sollen, kann als Kunststoffhülle statt einer glatten Folie eine Dachfolie verwendet werden. Derartige Dachfolien weisen in axialer Richtung benachbarte ringförmige Abschnitte auf, die mit in Richtung der Längsachse des Sprenggeschosses sich erstreckende dachförmige Ausstülpungen versehen sind, wobei die dachförmigen Ausstülpungen benachbarter ringförmiger Abschnitte jeweils um ein halbes Dach zueinander versetzt angeordnet sind. If in the detonation of the explosive projectile in a simple way preformed fragments can be produced as a plastic envelope instead of a smooth film, a roof liner be used.
