Description

Die Neuerung betrifft einen Penetrator mit einer Sprengladung und einer Zündvorrichtung, dessen Sprengladung aus zumindest einer Teilladung und einer Einlage besteht, welche innerhalb der Hülle des Penetrators angeordnet ist, wobei die Zündvorrichtung am Heck des Penetrators fest montiert ist und mit einer Verstärkerladung verbunden ist.The innovation relates to a penetrator with an explosive charge and an ignition device, the explosive charge consists of at least a partial charge and a deposit which is disposed within the shell of the penetrator, wherein the igniter is fixedly mounted at the rear of the penetrator and connected to a booster charge.

Penetratoren sind Wirksysteme, die aufgrund ihres konstruktiven Aufbaus geeignet sind, widerstandsfähige Strukturen wie beispielsweise Gebäudewände aus Ziegel oder Beton oder auch Fels zu durchdringen. Bei der Bekämpfung derartiger Strukturen durch einen mit einer Hohlladung ausgestatteten Penetrator steht die Wirkung der gerichteten Hohlladung nicht mehr unbedingt im Vordergrund. Vielmehr ist es von Interesse, dass der Penetrator nach dem Durchdringen der Struktur in der Lage ist, im Raum hinter der Struktur eine möglichst hohe Blast- und/oder Splitterleistung zu entfalten. Anderenfalls kann die Mission nur unzureichend erfüllt werden.Penetrators are active systems which, due to their structural design, are suitable for penetrating resistant structures such as building walls made of brick or concrete or even rock. When combating such structures by a penetrator equipped with a hollow charge, the effect of the directed hollow charge is no longer in the foreground. Rather, it is of interest that the penetrator after penetrating the structure is able to develop in the space behind the structure as high as possible blast and / or splintering performance. Otherwise, the mission can not be adequately fulfilled.

Der Neuerung liegt das Problem zugrunde, dass einerseits hochfeste und dicke Strukturen perforiert werden müssen. Dies erfordert schnelle und schlanke Penetratoren mit einer entsprechenden Sprengladung, der eine Einlage und ein vorgelagerter Hohlraum in der Spitze des Penetrators zugeordnet sind. Andererseits erfahren der Penetrator und damit auch die Sprengladung beim Perforationsvorgang eine sehr hohe negative Beschleunigung, die dazu führt, dass sich die Sprengladung aufgrund des Umstülpens der Einlage zur Penetratorspitze hin bewegt. Diese Bewegung der Sprengladung hin zur Penetratorspitze und weg von der Zündeinrichtung birgt die Gefahr, dass Abstände insbesondere von der Verstärkerladung zur Sprengladung zu groß werden und eine sichere Initiierung der Sprengladung nicht mehr gewährleistet ist.The innovation is based on the problem that on the one hand high-strength and thick structures must be perforated. This requires fast and slim penetrators with a corresponding explosive charge associated with a liner and an upstream cavity in the tip of the penetrator. On the other hand, the penetrator and thus also the explosive charge in the perforation experienced a very high negative acceleration, which causes the explosive charge moves due to the everting of the insert to Penetratorspitze out. This movement of the explosive charge towards the penetrator tip and away from the ignition device involves the risk that distances, in particular from the booster charge to the explosive charge become too large and a safe initiation of the explosive charge is no longer guaranteed.

Aus der DE 10 2007 035 551 A1 ist aufgrund dieses Problems eine Stützvorrichtung für ein Kombinationswirksystem bestehend aus einem Penetrator mit integrierter Hohlladung bekannt geworden. Diese Stützvorrichtung verhindert bei der Zielpenetration die Vorwärtsbewegung der Sprengladung. Gleichzeitig wird auch die mögliche Ausbildung einer übermäßig großen Lücke zwischen dem Zündsystem und der Sprengladung vermieden, welche die Initiierung verhindern kann.From the DE 10 2007 035 551 A1 is due to this problem, a support device for a combination control system consisting of a penetrator with integrated hollow charge known. This support device prevents the forward movement of the explosive charge at the Zielpenetration. At the same time the possible formation of an excessively large gap between the ignition system and the explosive charge is avoided, which can prevent the initiation.

Es werden verschiedene Abstützvorrichtungen vorgeschlagen. Vielen davon ist es gemeinsam, dass sie in die Sprengladung integriert sein müssen. Dies hat nahe der Hohlladungs-Einlage zu erfolgen, da diese selbst in der Regel nur sehr eingeschränkt die Sprengladung abstützen kann. Die Einlage ist konstruktiv so ausgelegt, dass sie eine hohe Hohlladungsleistung unterstützt, eine mechanische Stützfunktion ist jedoch nicht vorgesehen und auch nicht mit der Hauptaufgabe zu vereinbaren.Various support devices are proposed. Many of them have in common that they must be integrated into the explosive charge. This has to be done near the shaped charge insert, since this can only very limited support the explosive charge itself in the rule. The insert is structurally designed to support a high hollow charge performance, but a mechanical support function is not provided and also not compatible with the main task.

Stützvorrichtungen in der Nähe der Hohlladungs-Einlage können aber auch insofern problematisch sein, da diese die optimale Ausbildung des Stachels stören können. Bei langen Penetratoren kommt als weiterer Aspekt dazu, dass die Zündung der Sprengladung relativ weit von der Hohlladungs-Einlage entfernt ist und dadurch die Detonationswelle eher streifend als frontal auf die Hohlladungs-Einlage trifft. Dies führt in der Regel zur Leistungsreduktion.However, support devices in the vicinity of the shaped charge insert can also be problematic in that they can interfere with the optimal formation of the spine. In the case of long penetrators, a further aspect is that the ignition of the explosive charge is relatively far away from the shaped charge insert and, as a result, the detonation wave strikes the shaped charge insert in a grazing rather than frontal manner. This usually leads to power reduction.

Aus der US 6 467 416 B1 ist ein Gefechtskopf mit einer Spitze aus Metall, vorzugsweise Aluminium, beschrieben, der eine am Heck des Gefechtskopfgehäuses montierte Zündvorrichtung für die Sprengladung aufweist, die mit einer Verstärkerladung in Form eines Detonators verbunden ist, die unmittelbar auf das hochexplosive Zündelement einwirkt. Die Verstärkerladung und das Zündelement sind in einem rohrförmigen Gehäuse untergebracht, welches sich in Längsrichtung des Gefechtskopfes erstreckt. Im Fall einer Penetration würde sich die Einlage umstülpen und die Sprengladung hätte keinen Kontakt mehr zum Zündelement.From the US Pat. No. 6,467,416 B1 there is described a warhead with a tip of metal, preferably aluminum, which has an explosive charge detonator mounted on the rear of the warhead casing which is connected to a booster charge in the form of a detonator which acts directly on the high explosive ignition element. The booster charge and the ignition element are housed in a tubular housing which extends in the longitudinal direction of the warhead. In the case of one Penetration, the insert would evert and the explosive charge would have no contact with the ignition element.

Der Neuerung liegt deshalb die Aufgabe zugrunde, einen Lösungsansatz aufzuzeigen, der einen Verzicht auf die beschriebenen Stützvorrichtungen ermöglicht und die Ausbildung von Detonationsfronten zur Folge hat, welche die Stachelausbildung und die Stachelleistung unterstützt.The novelty is therefore the object of demonstrating a solution that allows a waiver of the support devices described and the formation of detonation fronts result, which supports the spine training and the stinging performance.

Die Aufgabe wird durch die Merkmale des Anspruches 1 gelöst.The object is solved by the features of claim 1.

Damit wird auf einfache Weise das Problem der Überbrückung eines nicht mit Sprengstoff gefüllten Hohlraumes gelöst. Gleichzeitig kann die Entfernung der Verstärkerladung zur Einlage soweit verkürzt werden, dass in jedem Fall eine Initiierung nach dem Zieldurchgang möglich ist, weil ein frontales Auftreffen der Detonationsfront auf die Einlage gewährleistet ist.This solves the problem of bridging a non-explosive filled cavity in a simple manner. At the same time, the distance of the booster charge to the deposit can be shortened so far that in each case an initiation after the target passage is possible because a frontal impact of the detonation front is ensured on the deposit.

Besonders günstig auf den Verlauf der Detonationswellen wirkt sich aus, dass zwischen der Verstärkerladung und der Einlage ein Detonationswellenlenker DWL angeordnet ist.A particularly favorable effect on the course of the detonation waves is that a detonation waveguide DWL is arranged between the amplifier charge and the insert.

Eine besonders einfache und stabile Bauform ergibt sich, wenn der Abstandhalter als rohrförmiges Bauteil ausgeführt ist.A particularly simple and stable design results when the spacer is designed as a tubular component.

Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung schematisch vereinfacht dargestellt und wird im Folgenden näher beschrieben. Es zeigen:

An embodiment of the innovation is shown schematically simplified in the drawing and will be described in more detail below. Show it:

Fig. 2:
a penetrator according to Fig. 1 after the perforation of a target,

Gemäß Figur 1 wird als Lösung für die Problemstellung eine Zündvorrichtung vorgeschlagen, bei der die Verstärkerladung V in einem Abstand L von der konventionell am Heck der Hülle H des Penetrators befestigten Zündvorrichtung Z angeordnet ist. Dies wird im Ausführungsbeispiel mit einem Abstandhalter A in der Form einer zylinderförmig gestalteten Vorrichtung erreicht. Diese ist zwar mit der Zündvorrichtung wirkungsmäßig verbunden, sie ist aber völlig entkoppelt von der Sprengladung SP. Die Verstärkerladung V ist dabei an demjenigen Ende des Abstandhalters A angeordnet, der in Richtung der Längsachse LA des Penetrators der Einlage E am nächsten liegt.According to FIG. 1 is proposed as a solution to the problem an ignition device in which the booster charge V is disposed at a distance L from the ignition device Z conventionally attached to the stern of the shell H of the penetrator. This is achieved in the embodiment with a spacer A in the form of a cylindrical shaped device. Although this is operatively connected to the ignition device, but it is completely decoupled from the explosive charge SP. The booster charge V is arranged at that end of the spacer A, which lies closest to the insert E in the direction of the longitudinal axis LA of the penetrator.

Die Dimensionierung und individuelle Gestaltung kann in weiten Bereichen an die für den jeweiligen Penetrator spezifischen Erfordernisse angepasst werden.The dimensioning and individual design can be adapted to a large extent to the requirements specific to the respective penetrator.

In der Figur 2 ist die Funktion der Zündvorrichtung mit Abstandhalter vereinfacht dargestellt. Wenn ein Penetrator wie er in Figur 1 dargestellt ist ein Ziel durchdringt bewegt sich aufgrund der starken Verzögerung die Sprengladung SP in Richtung der Penetratorspitze. Üblicherweise handelt es sich hierbei um eine kunststoffgebundene und somit plastisch leicht verformbare Sprengladung, die derartige Verformungen toleriert ohne dabei zu einer Reaktion angeregt zu werden.In the FIG. 2 the function of the igniter with spacers is simplified. If a penetrator like him in FIG. 1 a target is shown penetrating moves the explosive charge SP toward the Penetratorspitze due to the strong delay. Usually, this is a plastic-bonded and thus plastically easily deformable explosive charge, which tolerates such deformations without being stimulated to a reaction.

Die Einlage E des Penetrators stützt sich gemäß Figur 1 mit ihrem Rand an der Hülle H des Penetrators ab. Sie kann jedoch konstruktiv bedingt im Fall einer Zielpenetration die in Richtung der Penetratorspitze drängende Sprengladung SP nicht aufhalten. Somit stülpt sich die Einlage E um und liegt nun an der Innenseite der Hülle des Penetrators an. Das vorher von der Einlage E und der Spitze des Penetrators gebildete leere Volumen HO ist dann aufgrund des hohen Pressdruckes in der Sprengladung SP vollständig mit dieser aufgefüllt. Dafür hat sich am Heck des Penetrators angrenzend an die Zündvorrichtung Z ein anderer Hohlraum HR gebildet. Auch wenn die Verstärkerladung V nicht gänzlich von der Sprengladung SP umgeben ist und sich dadurch ein gewisses Leervolumen unmittelbar vor der Verstärkerladung bilden kann, ist dies hinsichtlich der Funktionalität nicht hinderlich, da die Zündung der Sprengladung mittels der Verstärkerladung radial über den Mantel der Verstärkerladung erfolgt.The insert E of the penetrator is supported according to FIG. 1 with its edge on the shell H of the penetrator. However, it can be structurally conditioned in the case of a Zielpenetration the urging towards the Penetratorspitze explosive charge SP do not stop. Thus, the insert E inverts and now lies against the inside of the shell of the penetrator. The empty volume HO previously formed by the insert E and the tip of the penetrator is then completely filled with it due to the high pressing pressure in the explosive charge SP. For this, another cavity HR has formed at the rear of the penetrator adjacent to the ignition device Z. Even if the booster charge V is not completely surrounded by the explosive charge SP and thereby can form a certain void volume immediately before the booster charge, this is not a hindrance in terms of functionality, since the ignition of the explosive charge by means of the booster charge takes place radially over the jacket of the booster charge.

Die Länge des Abstandhalters A ist nun so ausgelegt, dass die Verstärkerladung V auf alle Fälle im Bereich der verformten Sprengladung SP verbleibt. Die Zündung der Verstärkerladung V führt somit zur gewollten Detonation der Sprengladung.The length of the spacer A is now designed so that the booster charge V remains in all cases in the area of the deformed explosive charge SP. The ignition of the booster charge V thus leads to the intentional detonation of the explosive charge.

Eine vorteilhafte Ausgestaltung besonders bei sehr langen Penetratoren ist es, den Abstandshalter in der Längenausdehnung flexibel zu gestalten, so dass er der Vorwärtsbewegung der Sprengladung weitestgehend folgt und so auf keinen Fall der Kontakt zu dieser verloren geht, wodurch eine sichere Zündung gewährleistet ist. Eine solche variable Längenausdehnung kann beispielsweise durch ein teleskopartig ausgelegtes Gehäuse, oder durch ein zick-zack-gefaltetes Gehäuse (ähnlich Ziehharmonika-Effekt) erzielt werden. Diese Art von Abstandshalter-Gehäusen ist nicht in den Figuren dargestellt. Weitere flexible Ausgestaltungen sind durch angepasste Konstruktionen denkbar, sollen aber hier nicht weiter aufgezählt werden.An advantageous embodiment, especially for very long penetrators, is to make the spacer in the longitudinal extent flexible, so that it largely follows the forward movement of the explosive charge and so in any case the contact is lost to this, whereby a reliable ignition is guaranteed. Such a variable length expansion can be achieved, for example, by a telescopically designed housing, or by a zigzag-folded housing (similar to the concertina effect). This type of spacer housing is not shown in the figures. Other flexible configurations are conceivable by adapted constructions, but should not be further enumerated here.

Eine weitere vorteilhafte Ausgestaltung ist in der Figur 3 dargestellt. Hierbei ist angrenzend an die Verstärkerladung und in Richtung zur Einlage E ein Detonationswellenlenker DWL oder Dämpfungselement vorgesehen. Falls der Penetrator in ein Ziel eingedrungen ist und sich die Sprengladung nach vorn verschoben hat, erfolgt eine Initiierung in der gleichen Weise wie sie gemäß Figur 2 beschrieben wurde.A further advantageous embodiment is in the FIG. 3 shown. In this case, a detonation waveguide DWL or damping element is provided adjacent to the booster charge and in the direction of the insert E. If the penetrator has penetrated into a target and the explosive charge is forward has been initiated, an initiation takes place in the same way as in accordance with FIG. 2 has been described.

Falls die Zündung der Sprengladung jedoch vor einer Zielpenetration erfolgt dann verläuft die Detonationswelle in der Sprengladung so wie in Figur 3 gestrichelt und mit den Bezugszeichen 1, 2, 3 bezeichnet dargestellt. Die durch den Detonationswellenlenker DWL abgelenkten Detonationswellenfronten werden radial auf die mit 1, 2, 3 bezeichneten Pfade gezwungen. Der Einfallswinkel auf die Einlage E ist damit deutlich steiler als wie bei einem Verlauf ohne einen Detonationswellenlenker DWL, der in der Figur 4 dargestellt ist.However, if the ignition of the explosive charge takes place before a target penetration, then the detonation wave in the explosive charge proceeds as in FIG. 3 dashed lines and designated by the reference numerals 1, 2, 3 shown. The detonation wavefronts deflected by the detonation waveguide DWL are forced radially onto the paths labeled 1, 2, 3. The angle of incidence on the insert E is thus significantly steeper than that of a course without a detonation waveguide DWL, which in the FIG. 4 is shown.

Ohne Detonationswellenlenker DWL wird nur ein streifender Einfall der Detonationswellenfront 1a, 2a, 3a erreicht, wodurch ein deutlicher Leistungsabfall gegenüber der anhand der Figur 3 beschriebenen Situation in Kauf zu nehmen ist.Without detonation waveguide DWL only a grazing incidence of the detonation wavefront 1a, 2a, 3a is achieved, whereby a significant drop in performance over that of the FIG. 3 situation is to be accepted.
