Description

Die Erfindung betrifft ein Sprenggeschoss mit einer Geschosshülle, die einen mit einem Sprengstoff gefüllten Innenraum umschließt. Die Erfindung bezieht sich ferner auf ein Verfahren zur Herstellung des Sprenggeschosses.The invention relates to an explosive projectile with a projectile casing, which encloses a space filled with an explosive interior. The invention further relates to a method for producing the explosive projectile.

Ein verkapseltes, leicht handhabbar gemachtes Sprengmittel beschreibt die DE 23 45 070 B2 , einen Sprengkörper die DE 38 43 443 A1 . Verschiedene Sprenggeschosse sind unter anderem aus der DE 602 02 419 T2 , der DE 601 08 817 T2 , der DE 20 2004 019 504 U1 , der DE 295 19 568 U1 , der DE 39 13 543 C1 sowie der DE 196 26 660 C2 bekannt.An encapsulated, easily manageable disintegrant describes the DE 23 45 070 B2 , an explosive device DE 38 43 443 A1 , Various explosive projectiles are among others from the DE 602 02 419 T2 , of the DE 601 08 817 T2 , of the DE 20 2004 019 504 U1 , of the DE 295 19 568 U1 , of the DE 39 13 543 C1 as well as the DE 196 26 660 C2 known.

Aus der EP 1 338 860 A2 ist ferner ein Verfahren zur Herstellung eines großkalibrigen Sprenggeschosses bekannt, bei dem sich in dem Innenraum der Geschosshülle eine kunststoffgebundene Sprengladung befindet, die in einem in das Geschoss eingebrachte entfaltbare Kunststoffhülle eingebracht wird.From the EP 1 338 860 A2 Furthermore, a method for producing a large-caliber explosive projectile is known in which in the interior of the projectile casing is a plastic-bound explosive charge, which is introduced into a deployed into the projectile unfoldable plastic shell.

Wird ein Sprengstoff in flüssiger Form verwendet, wird dieser in den Innenraum der Geschosshülle eingefüllt und anschließend ausgehärtet. Dabei kann es sowohl beim Gießen als auch beim Aushärten des Sprengstoffes zu Lunkerbildungen und gegebenenfalls auch zu Rissbildungen in dem Sprengstoff kommen. Derartige Lunker und Risse stellen ein nicht unwesentliches Sicherheitsrisiko dar, weil aufgrund der hohen Beschleunigung beim Abschuss des Sprenggeschosses die Lunker und Risse sehr schnell ihre Form ändern und sich die Luft in den Lunkern und Rissen aufgrund der dadurch auftretenden Kompression so stark erhitzen kann, dass es zu einer Zündung des entsprechenden Sprengstoffes kommt.If an explosive is used in liquid form, it is filled into the interior of the projectile casing and then cured. This can lead to cavities during the casting as well as during curing of the explosive and possibly also to cracks in the explosive. Such voids and cracks represent a not insignificant security risk, because due to the high acceleration at the launch of the explosive projectile blowholes and cracks change their shape very quickly and the air in the voids and cracks can heat up so much due to the resulting compression that it comes to an ignition of the corresponding explosive.

Es ist daher in der Regel erforderlich die Sprenggeschosse nach Einbringen und Aushärten des Sprengstoffes mittels einer Röntgenanlage auf Lunker und Risse zu überprüfen, was mit einem erheblichen Zeit- und Kostenaufwand verbunden ist.It is therefore usually necessary to inspect the explosive projectiles after introduction and curing of the explosive by means of an X-ray system for voids and cracks, which is associated with considerable time and expense.

Die US 2,373,883 A offenbart ein Sprenggeschoss, das eine einseitig nach oben offene Hülle aufweist, in die ein Sprengstoff eingebunden und die über die Seiten der Geschossnase gezogen ist. Dadurch wird es möglich, dass durch einen Angriff der Luft (Luftwiderstand) auf das Geschoss diese Seiten eine erste Ladung herausziehen und das Geschoss funktionsfähig wird.The US 2,373,883 A discloses an explosive projectile, which has a unilaterally upwardly open shell, in which an explosive incorporated and which is pulled over the sides of the projectile nose. This makes it possible that by attacking the air (air resistance) on the projectile these pages pull out a first charge and the bullet is functional.

Der Erfindung liegt die Aufgabe zugrunde, ein Sprenggeschoss anzugeben, bei dem die Gefahr einer ungewollten Zündung des Sprengstoffes beim Abschuss geringer ist als bei Sprenggeschossen mit ausgehärtetem Flüssigsprengstoff. Ferner soll die Erfindung ein Verfahren zur Herstellung eines derartigen Sprenggeschosses offenbaren.The invention has for its object to provide an explosive projectile in which the risk of accidental ignition of the explosive at launch is less than in explosive ordnance with hardened liquid explosive. Furthermore, the invention should disclose a method for producing such an explosive projectile.

Diese Aufgabe wird erfindungsgemäß hinsichtlich des Sprenggeschosses durch die Merkmale des Anspruchs 1 und hinsichtlich des Verfahrens durch die Merkmale des Anspruchs 5 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved with respect to the explosive projectile by the features of claim 1 and in terms of the method by the features of claim 5. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

Die Erfindung beruht im Wesentlichen auf dem Gedanken, als Sprengstoff einen Flüssigsprengstoff zu verwenden, welcher nach dem Einbringen in den Innenraum der Geschoßhülle nicht aushärtet, sondern flüssig bleibt. Dabei ist der Sprengstoff in dem Innenraum der Geschoßhülle in einer elastischen Hülle luftdicht abgeschlossen angeordnet.The invention is essentially based on the idea of using a liquid explosive as explosive, which does not harden after being introduced into the interior of the projectile casing, but remains liquid. In this case, the explosive is arranged airtight in the interior of the projectile casing in an elastic sheath.

Das erfindungsgemäße Sprenggeschoss weist unter anderem den Vorteil auf, dass es auf einfache Weise herstellbar ist, da der Sprengstoff bereits außerhalb der Geschosshülle in die beispielsweise aus Kunststoff bestehende Hülle eingebracht und luftdicht abgeschlossen werden kann. Dabei kann bereits zu diesem Zeitpunkt das Entstehen von Luftblasen innerhalb des Flüssigsprengstoffes beispielsweise durch Anschluss an eine entsprechende Vakuumeinrichtung weitgehend verhindert werden. Nach dem luftdichten Verschließen der Hülle wird diese dann zusammen mit dem Sprengstoff, beispielsweise von der Mündung der Geschosshülle aus, in diesen eingebracht, wobei die elastische Hülle ein unbeabsichtigtes Austreten des Flüssigsprengstoffes aus der Geschosshülle oder ein unbeabsichtigtes Eindringen von Luft in die elastische Hülle hinein sicher verhindert.The explosive projectile according to the invention has, inter alia, the advantage that it can be produced in a simple manner, since the explosive can already be introduced outside the projectile casing into the casing, which is made of plastic, for example, and can be hermetically sealed off. In this case, the formation of air bubbles within the liquid explosive, for example, by connection to a corresponding vacuum device can be largely prevented already at this time. After the envelope has been hermetically sealed, it is then introduced into the envelope together with the explosive, for example from the mouth of the projectile casing, the elastic casing ensuring that the liquid explosive leaks unintentionally from the projectile casing or accidental ingress of air into the elastic casing prevented.

Selbstverständlich muss die elastische Hülle aus einem Werkstoff bestehen, der sowohl mit dem Sprengstoff als auch mit den übrigen im Geschoss verwendeten Materialien (sofern diese mit der Hülle in Berührung kommen) verträglich ist, so dass die entsprechenden Werkstoffeigenschaften über einen längeren Zeitraum in dem vorgegebenen Temperaturbereich beibehalten werden. So ist es nicht selten, dass der Käufer entsprechender Sprenggeschosse eine Nutzungsdauer derartiger Geschosse von beispielsweise 25 Jahren vorschreibt.Of course, the elastic sheath must be made of a material that is compatible with both the explosive and the other materials used in the projectile (if they come into contact with the sheath), so that the corresponding material properties over a longer period in the specified temperature range to be kept. So it is not uncommon that the buyer of corresponding explosive projectiles requires a useful life of such bullets of, for example, 25 years.

Vorzugsweise wird die elastische Hülle in einem Teilbereich mit der Innenwand der Geschosshülle verklebt. Auf diese Weise kann sich der Flüssigsprengstoff im Innenraum der Geschosshülle nicht undefiniert bewegen. Dabei sollte ein Freiraum zwischen der elastischen Hülle und der Geschosshülle verbleiben, damit sich die elastische Hülle bei einer Temperaturausdehnung des Sprengstoffes innerhalb des Innenraumes ausdehnen kann, ohne die Geschosshülle zu deformieren.Preferably, the elastic sheath is glued in a partial area with the inner wall of the projectile casing. In this way, the liquid explosive in the interior of the projectile casing can not move undefined. In this case, a space between the elastic sheath and the projectile casing should remain so that the elastic sheath can expand at a temperature expansion of the explosive within the interior, without deforming the projectile casing.

Das Volumenausgleichselement kann beispielsweise aus einem Behälter bestehen, der mit einem komprimierbaren Gas oder einer komprimierbaren Flüssigkeit gefüllt ist. Das Volumenausgleichselement ist vorgeformt und auf die geplante Position in der Geschossogive angepasst. Beim Einführen, in einen Vakuum bzw. Unterdruck, in das Geschoss wird das Volumenausgleichselement vorzugsweise gefaltet oder zusammengedrückt. Durch die Vorformung des Volumenausgleichselements und das enthaltene Gas entspannt sich der Körper nach dem Einführen wieder und fügt sich in die Ogive ein beispielsweise dieser an. Der Klebstoff sollte vorher im Bereich der Ogive aufgebracht werden, wo das Volumenausgleichselement sitzen wird, um eine gleichmäßige Klebstoffschicht zu bekommen. Das Aufbringen kann vorzugsweise durch Aufspritzen erfolgen.The volume compensation element may for example consist of a container which is filled with a compressible gas or a compressible liquid. The volume compensation element is preformed and adjusted to the planned position in the store log. During insertion, in a vacuum or negative pressure, into the projectile, the volume compensation element is preferably folded or compressed. By preforming the volume compensation element and the gas contained the body relaxes after insertion again and fits into the ogive for example this one. The adhesive should first be applied in the area of the ogive, where the volume compensation element will sit, to get a uniform adhesive layer. The application can preferably be carried out by spraying.

Insbesondere bei der Verwendung von Sprenggeschossen mit Kopfzündern ist bei der Wahl des vorderseitig angeordneten Freiraumes darauf zu achten, dass der Abstand zwischen der elastischen Hülle bzw. dem Flüssigsprengstoff und dem Zünder nicht zu groß ist, damit eine definierte Anzündung des Sprengstoffes sicher gewährleistet ist.In particular, when using explosive projectiles with Kopfzündern care must be taken in the choice of the front side space that the distance between the elastic shell or the liquid explosive and the detonator is not too large, so that a defined ignition of the explosive is guaranteed safe.

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

Fig. 1
einen Längsschnitt durch ein schematisch dargestelltes drallstabilisiertes Sprenggeschoss (Artilleriegeschoss) ohne Kopfzünder mit in dem Innenraum der Geschosshülle angeordneten Flüssigsprengstoff, wobei vorderseitig ein Freiraum vorgesehen ist, und
Fig. 2
eine Fig. 1 entsprechende Ansicht, wobei vorderseitig ein den Freiraum ausfüllendes Volumenausgleichselement angeordnet ist.
Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it:
Fig. 1
a longitudinal section through a schematically represented spin-stabilized explosive projectile (artillery projectile) without a detonator with arranged in the interior of the projectile casing liquid explosives, wherein the front side a space is provided, and
Fig. 2
a Fig. 1 corresponding view, wherein the front side a space filling the volume compensation element is arranged.

In Fig. 1 ist mit 1 ein beispielsweise aus einer Panzerhaubitze verschießbares drallstabilisiertes Sprenggeschoss bezeichnet, welches eine Geschosshülle 2 aus Stahl umfasst, die vorderseitig eine Öffnung 3 aufweist, in welche ein nicht dargestellter Aufschlagzünder einschraubbar ist.In Fig. 1 1 denotes a spin-stabilized explosive projectile that can be fired, for example, from a tank howitzer, which comprises a projectile casing 2 made of steel, which has an opening 3 on the front side into which an impact fuse (not shown) can be screwed.

In der Geschosshülle 2 befindet sich ein in Richtung der Längsachse 4 des Sprenggeschosses 1 erstreckender Innenraum 5, der Sprengstoff 6 aufnimmt. Dabei handelt es sich bei dem Sprengstoff 6 erfindungsgemäß um Flüssigsprengstoff, der vollständig und luftdicht von einer elastischen Hülle 7 umschlossen ist.In the projectile casing 2 is an in the direction of the longitudinal axis 4 of the explosive projectile 1 extending interior 5, the explosive 6 receives. The explosive 6 according to the invention is liquid explosive which is completely and airtight enclosed by an elastic sheath 7.

Die elastische Hülle 7 ist im heckseitigen Bereich der Geschosshülle 2 mit der Innenwand 11 der Geschosshülle 2 verklebt, während zwischen der elastischen Hülle 7 und der Geschosshülle 2 vorderseitig ein Freiraum 9 verbleibt. Dieser Freiraum 9 ist einerseits derartig gewählt, dass sich die elastische Hülle 7, und damit der Flüssigsprengstoff 6, bei Temperaturänderungen ungehindert ausdehnen kann. Andererseits ist der Abstand zwischen der elastischen Hülle 7 und dem nicht dargestellten Zünder derart gewählt, dass eine Anzündung des Flüssigsprengstoffes 6 durch den Zünder sicher gewährleistet ist.The elastic shell 7 is glued in the rear-side region of the projectile casing 2 with the inner wall 11 of the projectile casing 2, while between the elastic casing 7 and the projectile casing 2, a free space 9 remains on the front side. This clearance 9 is on the one hand chosen such that the elastic sheath 7, and thus the liquid explosive 6, can expand unhindered with temperature changes. On the other hand, the distance between the elastic sheath 7 and the detonator, not shown, is selected such that ignition of the liquid explosive 6 is ensured by the fuze safely.

Zur Herstellung des Sprenggeschosses 1 wird zunächst Flüssigsprengstoff 6 in die elastische Hülle 7 eingebracht und diese dann luftdicht verschlossen. Anschließend wird die elastische Hülle 7 mit dem darin befindlichen Flüssigsprengstoff 6 durch die Öffnung 3 in den Innenraum 5 der Geschosshülle 2 eingebracht und heckseitig mit der Geschosshülle 2 verklebt. Die entsprechende Klebeschicht wurde in Fig. 1 mit dem Bezugszeichen 10 gekennzeichnet.To produce the explosive projectile 1 liquid explosive 6 is first introduced into the elastic sheath 7 and then sealed airtight. Subsequently, the elastic shell 7 is inserted with the liquid explosive 6 therein through the opening 3 in the interior 5 of the projectile casing 2 and glued to the rear side with the projectile casing 2. The appropriate adhesive layer was in Fig. 1 marked with the reference numeral 10.

In Fig. 2 ist ein Sprenggeschoss 1' dargestellt, welches im Wesentlichen dem vorstehend beschriebenen Sprenggeschoss 1 entspricht. Es ist lediglich der bei dem Sprenggeschoss 1 vorgesehene Freiraum 9 durch ein elastisches Volumenausgleichselement 100 ausgefüllt, welches unter Vorspannung steht. Dabei besteht dieses Volumenausgleichselement 100 aus einem Behälter 101 (beispielsweise einer Kunststofffolie), in dem sich ein komprimierbares Gas (oder gegebenenfalls eine komprimierbare Flüssigkeit) befindet. Bei einer Erwärmung des Flüssigsprengstoffes wird dann das Volumenausgleichselement 100 durch die Ausdehnung des Sprengstoffes 6 zusammengedrückt. Bei einer Abkühlung des Flüssigsprengstoffes 6 dehnt sich das Volumenausgleichselement 100 hingegen aus, um in diesem Fall das Schrumpfen des Sprengstoffes auszugleichen.In Fig. 2 an explosive projectile 1 'is shown, which substantially corresponds to the explosive projectile 1 described above. It is merely the space provided at the explosive projectile 1 9 filled by an elastic volume compensation element 100, which is under bias. In this case, this volume compensation element 100 consists of a container 101 (for example, a plastic film) in which a compressible gas (or optionally a compressible liquid) is located. When heating the Flüssigsprengstoffes then the volume compensation element 100 is compressed by the expansion of the explosive 6. On cooling of the liquid explosive 6, however, the volume compensation element 100 expands to compensate for the shrinkage of the explosive in this case.
