Abstract

The device has a damping layer (3) sectionally extended over length of a mounting part (2) in a longitudinal direction (7a) of a penetrator, where the damping layer is attached to a casing (1). The damping layer is firmly connected with the casing of the penetrator at an outer side of the mounting part. The damping layer comprises openings at an outer surface of the damping layer. The openings correspond to circumferential devices with a toothed cross-section on an interior side of the casing of the penetrator or an outer side of the mounting part in a form-fit manner.

Description

Die Erfindung betrifft eine Dämpfungsvorrichtung für Einbauteile in Penetratoren mit einer an der Innenseite des Mantels anliegenden dämpfenden Schicht, welche wenigstens ein Einbauteil ringförmig umgibt und mittels Verformung die auf den Mantel einwirkenden Stoßwellen bedämpft und deren Wandstärke über die Länge der Schicht in Längsrichtung des Penetrators etwa konstant verläuft.The invention relates to a damping device for mounting parts in penetrators with a voltage applied to the inside of the jacket damping layer which surrounds at least one built-in part annular and deformed by deformation acting on the jacket shock waves and their wall thickness over the length of the layer in the longitudinal direction of the penetrator approximately constant runs.

Penetratoren sind bekannte Wirkmittel, die insbesondere zur Neutralisierung von hochwertigen Zielen eingesetzt werden. Darunter werden stark gehärtete Strukturen oder Objekte verstanden wie beispielsweise Kommandozentralen oder Kommunikationszentren. Die Penetratoren sind geeignet in das Ziel einzudringen. Die Initiierung erfolgt mittels intelligenter Zündeinrichtungen erst im Inneren des Zieles.Penetrators are known active ingredients which are used in particular for neutralizing high-quality targets. These include strongly hardened structures or objects such as command centers or communication centers. The penetrators are suitable to penetrate the target. The initiation takes place by means of intelligent ignition devices only in the interior of the target.

Die Anforderungen an derartige Penetratoren werden zunehmend höher. So wird beispielsweise zum Bau moderner Bunker hochfester Beton verwendet. Weiterhin existieren Stellungen in natürlicher Umgebung wie beispielsweise Höhlen in Felsen. Dieser Fels ist in der Regel noch härter als der hochfeste Beton. Um den daraus resultierenden Anforderungen gerecht zu werden, reduziert man die Kalibergröße der Penetratoren und erhöht deren Geschwindigkeit. Die Erhöhung der Geschwindigkeit hat jedoch unerwünschte Auswirkungen zur Folge. Bei der Penetration der äußeren Schichten des Zieles wird die Struktur des Penetrators stärker belastet. Beim Aufprall werden sehr starke Belastungen auf den Mantel des Penetrators ausgeübt und die entstehenden hochfrequenten Stoßwellen werden durch den steifen Penetratormantel nahezu ungedämpft in das Innere des Penetrators geleitet. Interne Komponenten können damit bei einer einfachen mechanischen Anbindung an den Penetratormantel bis zum Versagen belastet werden. In realen Penetratoren ist jedoch auch der axiale Bauraum zur Unterbringung einer wirksamen Dämpfungseinrichtung beschränkt. Je kleiner der Penetrator ausgeführt ist, desto größer werden aber die Beschleunigungen und die benötigte Wegstrecke zwischen dem Penetratormantel und den Einbauteilen im Inneren des Penetrators.The demands on such penetrators are increasingly higher. For example, high-strength concrete is used to construct modern bunkers. Furthermore, there are positions in natural environment such as caves in rocks. This rock is usually even harder than the high-strength concrete. In order to meet the resulting requirements, one reduces the caliber size of the penetrators and increases their speed. Increasing speed, however, has undesirable effects. Upon penetration of the outer layers of the target, the structure of the penetrator is more heavily loaded. Upon impact, very strong loads are exerted on the jacket of the penetrator and the resulting high-frequency shock waves are passed through the rigid penetrator jacket almost unattenuated into the interior of the penetrator. Internal components can be used with a simple mechanical Connection to the penetrator shell are charged to failure. In real penetrators, however, the axial space for accommodating an effective damping device is limited. However, the smaller the penetrator, the greater will be the accelerations and the required distance between the penetrator jacket and the built-in parts inside the penetrator.

Diese Abläufe haben eine wesentliche Auswirkung auf die im Inneren des Mantels gelagerten Einbauteile wie beispielweise die Zündeinrichtung und die Sprengladung, da diese stark unterschiedlichen Belastungen ausgesetzt werden. Zum einen entsteht eine stationäre Belastung durch die Verzögerung, die der Penetrator erfährt. Weiterhin tritt eine Schockwelle auf,
die durch den Penetrator läuft. Zusätzlich gibt es eine Schwingungsbelastung durch die Eigenschwingung und die Strukturschwingung des Penetrators. Schließlich sind noch lokale Kompression oder Dehnung aller in einem Penetrator vorhandenen Materialien zu berücksichtigen.These processes have a significant effect on the mounted inside the shell fixtures such as the ignition and the explosive charge, since they are exposed to very different loads. On the one hand, there is a stationary load due to the delay experienced by the penetrator. Furthermore, a shock wave occurs,
which runs through the penetrator. In addition, there is a vibration load due to the natural vibration and the structural vibration of the penetrator. Finally, local compression or elongation of all materials present in a penetrator must be considered.

Aus der DE 10 2005 009 931 B3 ist ein Penetrator bekannt geworden, der zum Schutz der in Inneren des Penetrators befindlichen Sprengladung verschiedene Anordnungen von Dämpfungsschichten aufweist. Dem Vorschlag entsprechend erstreckt sich die an der Innenseite des Mantels anliegende Schicht von der Spitze bis zum Heck des Mantels des Penetrators, wobei deren Stärke von der Spitze ausgehend abnimmt oder konstant bleibt. Die Dämpfungsschicht schützt die Sprengladung vor der Schockbelastung beim Aufprall und verhindert damit eine vorzeitige Detonation oder eine Sensibilisierung des Sprengstoffes. Die Druckschrift enthält jedoch keinen Hinweis auf eine effiziente Dämpfung von mechanischen Einbauteilen im Inneren des Penetrators. Eine Abstützung insbesondere von sich insbesondere im Heck eines Penetrators befindlichen Teilen ist mit Hilfe der beschriebenen Dämpfungsmittel nicht möglich.From the DE 10 2005 009 931 B3 For example, a penetrator has been disclosed that has various arrangements of damping layers for protecting the explosive charge inside the penetrator. According to the proposal, the voltage applied to the inside of the shell layer extends from the top to the rear of the shell of the penetrator, wherein the strength decreases from the tip or remains constant. The damping layer protects the explosive charge from the shock load on impact and thus prevents premature detonation or sensitization of the explosive. However, the document contains no indication of an efficient damping of mechanical components inside the penetrator. A support in particular of parts located in particular in the rear of a penetrator is not possible with the aid of the described damping means.

Der Erfindung liegt deshalb die Aufgabe zugrunde, zusätzlich zur bereits bekannten Dämpfung des im Inneren des Penetrators angeordneten Sprengstoffes eine wirksame Dämpfungseinrichtung für die weiteren Einbauteile vorzuschlagen.The invention is therefore based on the object, in addition to the already known damping of the explosive disposed inside the penetrator to propose an effective damping device for the other built-in parts.

Diese Aufgabe wird in einfacher Weise dadurch gelöst, dass die dämpfende Schicht sich zumindest abschnittsweise über die Länge wenigstens eines Einbauteils in Längsrichtung des Penetrators erstreckt und dass die dämpfende Schicht an einer Außenfläche mit dem Mantel des Penetrators oder der Außenseite des Einbauteils fest verbunden ist und dass die dämpfende Schicht in ihrer jeweils anderen Außenfläche Ausnehmungen aufweist, die mit umlaufenden Vorrichtungen mit etwa zahnförmigem Querschnitt auf der Innenseite des Mantels des Penetrators oder der Außenseite des Einbauteils formschlüssig korrespondieren.This object is achieved in a simple manner in that the damping layer extends at least in sections along the length of at least one built-in part in the longitudinal direction of the penetrator and that the damping layer is firmly connected on an outer surface with the jacket of the penetrator or the outside of the insert and that the damping layer has in its respective other outer surface recesses which correspond positively with peripheral devices with approximately tooth-shaped cross-section on the inside of the jacket of the penetrator or the outside of the insert.

Der besondere Vorteil dieser Anordnung liegt darin, dass die dämpfende Schicht sehr kompakt gehalten werden kann, da diese sich nicht zwangsläufig über die gesamte Länge eines Einbauteils oder gegebenenfalls auch eines weiteren Einbauteils erstreckt. Die Dämpfungsschicht kann sich auch nur über einen Teil der Länge des Einbauteils erstrecken oder sie kann einfach oder mehrfach in Ringe unterteilt sein.The particular advantage of this arrangement is that the damping layer can be kept very compact, since it does not necessarily extend over the entire length of a built-in part or possibly also a further built-in part. The damping layer may also extend over only a portion of the length of the insert or it may be divided into rings one or more times.

Da die mechanische Verbindung zwischen dem Einbauteil und dem Mantel im Wesentlichen nur über die Schicht verläuft, können die Dämpfungseigenschaften mittels Wahl der Geometrie und des Materials der Schicht in weiten Grenzen bestimmt werden. Durch die feste Verbindung der Schicht mit dem Mantel und dem Einbauteil wird bei Auftreten entsprechenderSince the mechanical connection between the mounting part and the jacket essentially extends only over the layer, the damping properties can be determined by selecting the geometry and the material of the layer within wide limits. Due to the firm connection of the layer with the jacket and the built-in is when appropriate

Beschleunigungen verformt und die zugeführte Energie in Form von Verformungsarbeit umgesetzt.Accelerations deformed and implemented the energy supplied in the form of deformation work.

Eine weitere Ausgestaltungsform ist dadurch gegeben, dass die aus den Ausnehmungen und Vorrichtungen bestehende Verzahnung ring- oder schraubenförmig verläuft. Mit der Art und Form der Verzahnung lässt sich die Schicht in einfacher Weise an die Situation bei der Montage des Einbauteils im Penetrator anpassen.A further embodiment is given by the fact that the toothing consisting of the recesses and devices is annular or helical. With the type and shape of the toothing, the layer can be easily adapted to the situation during assembly of the insert in the penetrator.

Eine weitere Verbesserung lässt sich dadurch erzielen, dass zusätzlich zur dämpfenden Schicht wenigstens eine weitere zur Längsrichtung konisch verlaufende und dämpfende Schicht vorgesehen ist. Damit lassen sich Bewegungen in Längs- und Querrichtung gezielt beeinflussen und dämpfen. Eine weitere Ausgestaltungsform besteht darin, dass die weitere konisch verlaufende und dämpfende Schicht in Flugrichtung vor der dämpfenden Schicht angeordnet ist.A further improvement can be achieved by providing, in addition to the damping layer, at least one additional layer which is tapered and attenuates to the longitudinal direction. This allows targeted movements in the longitudinal and transverse directions to be influenced and damped. Another embodiment is that the further conical and damping layer is arranged in the direction of flight in front of the damping layer.

Schließlich ist es von Vorteil, wenn zwischen dem Einbauteil und wenigstens einem weiteren im Innenraum des Penetrators angeordneten Bauteil wenigstens ein Einstellstück vorgesehen ist. Damit lässt sich eine Feinjustierung der Lage der Bauteile zueinander ermöglichen.Finally, it is advantageous if at least one adjusting piece is provided between the installation part and at least one further component arranged in the interior of the penetrator. This allows a fine adjustment of the position of the components to each other.

Ausführungsbeispiele der Erfindung sind in der Zeichnung vereinfacht dargestellt und werden im Folgenden anhand der Figuren näher beschrieben. Es zeigen:

Fig.
1: ein erstes Ausführungsbeispiel einer Dämpfungsvorrichtung,
Fig. 2:
eine weitere vereinfachte Ausführungsform einer Dämpfungs- vorrichtung.
Embodiments of the invention are shown in simplified form in the drawing and will be described in more detail below with reference to FIGS. Show it:
FIG.
1: a first embodiment of a damping device,
Fig. 2:
a further simplified embodiment of a damping device.

Die in Figur 1 dargestellte Dämpfungsvorrichtung 3 ist in einem Penetrator P zwischen dessen Mantel 1 und einem Einbauteil 2, beispielsweise einer Zündvorrichtung, montiert. In Flugrichtung 7b vor dem Einbauteil 2 befindet sich die Sprengladung 6. Die Dämpfungsschicht 3 ist so gestaltet, dass sie im unbelasteten Zustand fest sowohl mit dem Einbauteil 2 als auch mit dem Mantel 1 des Penetrators verbunden ist. Die Verbindung ist so gestaltet, dass durch die hohen Beschleunigungen beim Aufprall des Penetrators auf ein Ziel die Dämpfungsschicht verformt wird und die Energie in Form von Verformungsarbeit dissipiert wird.In the FIG. 1 shown damping device 3 is in a penetrator P between the jacket 1 and a built-in part 2, for example a Ignition device, mounted. In the direction of flight 7b in front of the built-in part 2 is the explosive charge 6. The damping layer 3 is designed so that it is firmly connected in the unloaded state both with the built-in part 2 and with the jacket 1 of the penetrator. The compound is designed so that the damping layer is deformed by the high accelerations on impact of the penetrator on a target and the energy is dissipated in the form of deformation work.

Diese Verbindung kann beispielsweise eine Verklebung zwischen der Dämpfungsschicht und der Innenseite des Mantels sein. Im Ausführungsbeispiel weist die Dämpfungsschicht 3 außerdem eine Reihe von Ausnehmungen 8 auf, in die auf der Außenseite des Einbauteils angebrachte Vorrichtungen mit etwa zahnförmigem Querschnitt formschlüssig eingreifen.This connection can be, for example, a bond between the damping layer and the inside of the jacket. In the exemplary embodiment, the damping layer 3 also has a series of recesses 8, in the mounted on the outside of the fixture devices with approximately tooth-shaped cross section engage positively.

Diese Verzahnung kann dabei ringförmig mit wenigstens einem umlaufenden Ring erfolgen oder auch in Form einer Helix.This toothing can be annular with at least one circumferential ring or in the form of a helix.

Durch diese Bauweise werden hochfrequente Beschleunigungen mit hoher Amplitude vermieden und ein gleichförmiges Beschleunigungsprofil mit einer geringen Maximalbeschleunigung erzielt.This construction avoids high-frequency accelerations with high amplitude and achieves a uniform acceleration profile with a low maximum acceleration.

Ergänzend zur Dämpfungsschicht 3 kann eine weitere Schicht 4a mit ähnlichen Eigenschaften vorgesehen sein, welche im Bereich einer Schulter 1a des Mantels 1 in der Form eines konischen Rings angeordnet ist und das Einbauteil 2 gegenüber der Schulter 1a abstützt.In addition to the damping layer 3, a further layer 4a may be provided with similar properties, which is arranged in the region of a shoulder 1a of the shell 1 in the form of a conical ring and the built-in part 2 is supported against the shoulder 1a.

In vorteilhafter Weise ist zwischen dem Einbauteil 2 und der Sprengladung 6 ein ein- oder mehrteiliger Abstandhalter 5 vorgesehen. Hilfreich ist es auch, zwischen dem Einbauteil 2 und der Rückwand des Mantels 1 eine zusätzliche weiche Schicht 4b anzuordnen, welche Schwingungen in Richtung der Hauptachse 7a des Penetrators zu bedämpfen vermag.In an advantageous manner, a single-part or multi-part spacer 5 is provided between the built-in part 2 and the explosive charge 6. It is also helpful to arrange an additional soft layer 4b between the built-in part 2 and the rear wall of the shell 1, which is capable of damping vibrations in the direction of the main axis 7a of the penetrator.

In der Figur 2 ist eine andere Ausführungsform der Dämpfungsschicht 3 dargestellt. Hierbei wird eine ringförmige konische Dämpfungsschicht 3 aus angepasstem Material eingesetzt, die an der Schulter 1a des Mantels 1 positioniert wird und den wesentlichen Teil der Verformungsarbeit aufnimmt. Zusätzlich kann eine weitere weiche Schicht 4a vorgesehen sein.In the FIG. 2 another embodiment of the damping layer 3 is shown. In this case, an annular conical damping layer 3 made of adapted material is used, which is positioned on the shoulder 1a of the shell 1 and absorbs the essential part of the deformation work. In addition, another soft layer 4a may be provided.

Der Öffnungswinkel des Mantels 1 erleichtert das Einbringen von komprimierbaren Materialen wie beispielsweise dem Sprengstoff 6. Durch den Konus erfolgt eine weiche Aufhängung des Einbauteils 2 in axialer Richtung 7a. dadurch werden die hochfrequenten Beschleunigungen hoher Amplitude vermieden und ein gleichförmiges Beschleunigungsprofil mit einer geringen Maximalbeschleunigung erzielt.The opening angle of the shell 1 facilitates the introduction of compressible materials such as the explosive 6. The cone is a soft suspension of the mounting part 2 in the axial direction 7a. This avoids the high-frequency high-amplitude accelerations and achieves a uniform acceleration profile with a low maximum acceleration.

Zur gezielten Einstellung dieses nach dem Prinzip eines Feder-Dämpfer-Prinzip arbeitenden Systems können zusätzliche konische oder ebene weiche Schichten 4b eingesetzt werden.For specific adjustment of this system operating on the principle of a spring-damper principle, additional conical or even soft layers 4b can be used.
