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 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 shell that contains an interior filled with an explosive charge encloses and has a mouth hole closable on the tip, through which the Explosive charge is brought into the interior of the explosive device. The invention also relates to an explosive projectile manufactured by this method is.

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 uses insensitive explosive charges required. These are usually plastic-bound explosive charges, which have a relatively high insensitivity despite a high active power. Plastic-bound explosive charges, however, have the disadvantage that they are have relatively large coefficients of thermal expansion, which are eight to twelve times larger is like that of a steel shell made of a corresponding one Explosive projectile. In such a storey filled with explosives positive temperatures so that the explosive body in the shell is held while the explosive body is at lower temperatures contracts and then lies loosely in the shell.

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 has for its object a method for producing a large-caliber Specify explosive storey, even when using plastic-bound Explosive charges of the explosive bodies even with large temperature fluctuations is always kept under tension in the shell.

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 claim 1 and with regard to the explosive device by the features of the claim 9 solved. Reveal further, particularly advantageous embodiments of the invention the subclaims.

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 essentially based on the idea that the explosive charge in one Arrange plastic cover made of an elastic material in the explosive storey, so that the changing volume of the explosive charge due to temperature fluctuations the elastic plastic cover is added. Because with large-caliber spin-stabilized Artillery shells generally only charge the corresponding explosive charge a front small mouth hole (head fuse holder) can be filled, it is not possible, explosive charges already packaged in plastic films in the interior to bring such an explosive device. The invention therefore proposes through the mouth hole only a folded or compressed, inserting a bag-shaped plastic cover into the interior of the explosive device, their dimensions in the unfolded state essentially the dimensions corresponds to the interior of the explosive device. Then the Plastic cover e.g. by inflation or due to their elastic restoring forces unfolded so that they form-fit on the inner walls of the interior of the explosive device is applied. Then the pourable plastic-bound explosive charge also becomes inserted through the mouth hole in the plastic shell. After polymerizing of the plastic-bound explosives, the mouth hole is e.g. by screwing in a head detonator closed.

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. To achieve that even with large temperature fluctuations, the explosive body can be held under tension in the shell, it has proven to be Proven to provide additional clamping devices that are compared to the Compensate for the shell volume 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 proven to be advantageous if before closing the mouth hole an elastic shim is placed on the explosive charge when screwing in the igniter or an adapter part connected to the igniter something is pressed together by these parts, so that the explosive charge is constantly below Preload is there.

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 order to ensure good swirl transmission between the To ensure the projectile shell and the explosive charge, the plastic shell with the Inner wall of the interior of the explosive bullet glued at least in some areas become. In addition, the swirl transmission from the shell to the Explosives are promoted in that the walls of the interior at least in have a polygonal configuration in a partial area on the bottom.

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, tests by the applicant have shown that when the inventive Explosive projectile good swirl transmission even without special measures between the shell and a plastic-bound explosive charge takes place because the explosive mass when fired due to the plastic portion deformed and "sticks" together with the plastic casing in the projectile casing.

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 and one Trade roof film with which preformed after detonation of the explosive charge Splinters can be generated. For this purpose, annular sections are in the direction of Roof-shaped protrusions extending along the longitudinal axis of the explosive projectile provided, the roof-shaped protuberances of adjacent annular sections are offset from each other by half a roof.

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.It has to ensure a quick and safe detonation of the explosive charge proved to be advantageous if the igniter is followed by an amplifier charge is that on the side facing the explosive charge the contour of a shaped charge insert and if the shim has an axially extending central recess has, so that the resulting after ignition of the booster charge Hollow charge jet reaches the explosive charge unhindered. It can be the Contour of the shaped charge insert 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 accelerate the ignition process further, is in a further embodiment the invention provided that located on the central recess of the shim an ignition tube extends axially into the explosive charge, at whose the End of the compensating disc is arranged a lighting set.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den folgenden anhand von Figuren erläuterten Ausführungsbeispielen. Es zeigen:

  • Fig.1 den Längsschnitt durch ein erstes Ausführungsbeispiel eines erfindungsgemäßen Sprenggeschosses;
  • Fig.2 einen Querschnitt durch das in Fig.1 dargestellte Sprenggeschoß entlang der mit II-II bezeichneten Schnittlinie;
  • Fig.3 den Längsschnitt durch ein zweites Ausführungsbeispiel eines erfindungsgemäßen Sprenggeschosses.
    • Further details and advantages of the invention result from the following exemplary embodiments explained with reference to figures. Show it:
  • 1 shows the longitudinal section through a first embodiment of an explosive device according to the invention;
  • 2 shows a cross section through the explosive projectile shown in Figure 1 along the section line designated II-II;
  • 3 shows the longitudinal section through a second embodiment of an explosive device according to the invention.

    • 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 denotes a large-caliber spin-stabilized explosive projectile, as is the case for example, can be fired from a self-propelled howitzer. The explosive storey 1 comprises a projectile casing 2 with a base part 3 and a front detonator 4. The head igniter 4 is screwed into an adapter part 17, which in turn is screwed into a mouth hole 5 of the shell 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 shell 2 surrounds an interior 6, with the inner walls 7 a bag-shaped trained elastic (rubber-like) plastic sleeve 8 is glued, in which there is a plastic-bound explosive charge 9. The plastic shell 8 has thereby a smooth surface. The wall thickness of the plastic sleeve 8 is advantageously between 0.3 and 0.6 mm. It has also proven advantageous if a plastic with about 30% rubber content is used as the material for the plastic sleeve 8 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 area 10 of the explosive projectile 1, the shell 2 and the plastic casing 8 to ensure good swirl transmission from the projectile casing 2 on the explosive charge 9 a polygonal design (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.The explosive charge 9 is closed off at the front by an elastic shim 11, on the side facing away from the explosive charge 9, the adapter part 17 a exerts predetermined pressure, so that the explosive charge 9 is under tension.

    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 igniter 4 protrudes from the rear into the adapter part 17, which has an amplifier charge 12 comprises, on the side facing the explosive charge 9, the contour of a shaped charge insert 13 has. In addition, the shim 11 has an axially extending recess 14, so that after the ignition of the booster charge 12 resulting shaped charge jet passes through this recess 14 into 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 incorporate the explosive charge 9 into the explosive storey 1, first if necessary Glue applied to the inner walls 7 of the shell 2. Subsequently the plastic sleeve 8 is compressed such that it passes through the mouth hole 5 can slide into the interior 6. In the interior 6, the plastic sleeve 8 is due of the internal tensions again and lies on the inner walls 7 the shell 2. The explosive charge 9 can then be inserted into the plastic casing 8 introduced and the elastic shim 11 arranged on the explosive charge 9 become. Finally, the adapter part 17 is then 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.The invention is of course not based on the embodiment described above limited. As can be seen from the explosive projectile 1 'shown in FIG is, the elastic shim marked there with 11 'needs itself do not extend over the entire cross section of the interior 6 'of the shell 2'. The adapter part 17 'is in this case completely inside the shell 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, the explosive charge 9 'can be used for rapid and uniform ignition Ignition tube 15 may be provided, which is located on the recess 14 'of the shim 11 'connects and extends axially into the explosive charge 9'. To the The ignition tube 15 has a firing set from the end facing away from the compensating disk 11 ' 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. Provided preformed fragments in a simple manner when detonating the explosive device should be generated, a roof film can be used as a plastic cover instead of a smooth film be used. Such roof foils have adjacent ones in the axial direction ring-shaped sections with the direction of the longitudinal axis of the explosive device extending roof-shaped protuberances are provided, the roof-shaped Protrusions of adjacent annular sections each by half a roof to each other are staggered.
