Description

Die Erfindung bezieht sich auf eine zylindrische Hohlladung mit einer abgestuften Einlage nach dem Oberbegriff des Anspruches 1.The invention relates to a cylindrical shaped charge with a stepped insert according to the preamble of claim 1.

Aus der US-A 3 478 658 ist eine zylindrische Hohlladung gemäß dem Oberbegriff des Anspruches 1 mit einer abgestuften Einlage aus Metall bekannt. Die Einlage weist basisseitig einen Einlagenabschnitt mit einer größeren Masse und einem größeren Öffnungswinkel auf als ein kopfseitiger Einlagenabschnitt.From US-A 3 478 658 a cylindrical shaped charge according to the preamble of claim 1 with a stepped insert made of metal is known. The insert has an insert section on the base side with a larger mass and a larger opening angle than an insert section on the head side.

Nach Zündung der Hohlladung wird ein massearmes Vorgeschoß über den kopfseitigen Einlagenabschnitt und zeitlich versetzt ein massereiches Hauptgeschoß über den basisseitigen, massereichen Einlagenabschnitt erzeugt. Der Übergang zwischen den Einlageabschnitten ist kurz und durch eine Einschnürung nahezu stufenförmig.After the shaped charge has been ignited, a low-mass projectile is created over the head-side insert section and, at different times, a massive main storey is created over the base-side, massive insert section. The transition between the insert sections is short and almost constricted due to a constriction.

Diese Hohlladung ist Bestandteil einer Mine zur Panzerbekämpfung, wobei die Mine von einer Erdschicht bedeckt ist. Das Vorgeschoß hat dabei die Aufgabe, das Erdreich zu beseitigen, damit das Hauptgeschoß eins freie Flugbahn hat.This shaped charge is part of a mine to combat tanks, the mine being covered by a layer of earth. The front floor has the task of clearing the ground so that the main floor has a free trajectory.

Zur Durchdringung einer sog. aktiven Panzerung, bei der vor der eigentlichen Hauptpanzerung durch Sprengstoff beschleunigte Panzerplatten angeordnet sind, eignet sich diese Hohlladung nicht. Denn der durch das Vorgeschoß initiierte Sprengstoff beschleunigt entgegen der Flugrichtung des Hauptgeschosses Panzerplatten, die die Energie des Vorgeschosses und des Hauptgeschosses weitgehend aufzehren.This shaped charge is not suitable for penetrating a so-called active armor, in which armor plates accelerated by explosives are arranged in front of the main armor. Because the explosives initiated by the first floor accelerate armor plates against the direction of flight of the main floor, which largely consume the energy of the first floor and the main floor.

Aus der DE-A 1 571 283 ist eine zylindrische Hohlladung mit einer einstückigen, tulpenförmigen Einlage aus Metall bekannt.DE-A 1 571 283 discloses a cylindrical shaped charge with a one-piece, tulip-shaped insert made of metal.

Die FR-A 1 327 804 zeigt eine Schneidladung mit einer leistungsfördemden zweiteiligen Einlage. Der kopfseitige Einlagenabschnitt besteht aus einem Edelmetall, während der basisseitige Einlagenabschnitt aus Kupfer besteht.FR-A 1 327 804 shows a cutting load with a performance-enhancing two-part insert. The head-side insert section consists of a precious metal, while the base-side insert section consists of copper.

Beide Ladungen erzeugen einen geschlossenen Partikelstrahl. Ein geschlossener Partikelstrahl wird jedoch bei aktiven Panzerungen eliminiert. Die durch Sprengstoff beschleunigten Panzerplatten vernichten den einfallenden Partikelstrahl.Both charges create a closed particle beam. A closed particle beam is eliminated with active armor. The armor plates accelerated by explosives destroy the incoming particle beam.

Der Erfindung liegt daher die Aufgabe zugrunde, eine zylindrische Hohlladung zu schaffen, die die aktive Panzerung überwindet und die Hauptpanzerung durchschlägt.The invention is therefore based on the object of creating a cylindrical shaped charge which overcomes the active armor and penetrates the main armor.

Die Erfindung löst diese Aufgabe gemäß den kennzeichenden Merkmalen des Anspruches 1.The invention solves this problem according to the characterizing features of claim 1.

Damit wird der Vorteil erzielt, daß der Vorstrahl die Sperrwirkung der aktiven Panzerung eliminiert, bevor der Hauptstrahl auf die Panzerung auftrifft. Der Hauptstrahl durchschlägt dann diese.This has the advantage that the pre-beam eliminates the blocking effect of the active armor before the main beam hits the armor. The main beam then passes through it.

Weitere Vorteile der Erfindung gehen aus der anschließenden Beschreibung zweier Ausführungsbeispiele hervor.Further advantages of the invention emerge from the subsequent description of two exemplary embodiments.

Es zeigt:

  • Fig. 1 eine bekannte Hohlladung nach der DE-A 1 571 283;
  • Fig. 2 und 3 mit der Fig. 1 kalibergleiche Hohlladungen nach der Erfindung;
  • Fig. 4 die von den erfindungsgemäßen Hohlladungen nach den Figuren 2 und 3 erzeugten Strahlen.
It shows:
  • 1 shows a known shaped charge according to DE-A 1 571 283;
  • Fig. 2 and 3 with the 1 caliber shaped charges according to the invention;
  • 4 shows the rays generated by the shaped charges according to the invention according to FIGS. 2 and 3.

Nach Fig. 1 weist eine Einlage 1 einer zylindrischen Hohlladung 2 eine durch Kreisabschnitte 3 und 4 und einen Geradabschnitt 5 gebildete Tulpenform auf. Eine Hülle 6 verdämmt einen Sprengstoff1, an insert 1 of a cylindrical shaped charge 2 has a tulip shape formed by circular sections 3 and 4 and a straight section 5. An envelope 6 insulates an explosive

7. Ein Körper 8 dient zur Detonationswellen-Lenkung. Eine Zündkapsel ist mit 9 und die Länge der Hohlladung 2 mit 12 bezeichnet. Die Basis 10 der Einlage 1 ist kleiner als der Innendurchmesser 11 des Gehäuses 6. Damit ist auch die Basis 10 mit dem Sprengstoff 7 bewegt. Mit dieser Einlage 1 wird eine geschlossener Partikelstrahl mit gestreckter Strahlspitze erreicht. Bei aktiven Panzerungen zerstört dieser Partikelstrahl nur den Schutzmechanismus nicht jedoch die Hauptpanzerung.7. A body 8 is used for detonation wave guidance. A primer is 9 and the length of the shaped charge 2 12. The base 10 of the insert 1 is smaller than the inside diameter 11 of the housing 6. The base 10 is also moved with the explosive 7. With this insert 1, a closed particle beam with an extended beam tip is achieved. With active armor, this particle beam only destroys the protective mechanism and not the main armor.

Dagegen liegt nach den Figuren 2 und 3 mit den zylindrischen Hohlladungen 20 und 30 gemäß Fig. 4 ein schneller, massearmer Vorstrahl 40 und im Abstand 41 ein massereicher Hauptstrahl 41 vor. Dies wird erreicht durch zwei Einlagenabschnitte 21, 22 und 31, 32.In contrast, according to FIGS. 2 and 3 with the cylindrical shaped charges 20 and 30 according to FIG. 4 there is a fast, low-mass pre-jet 40 and at a distance 41 a high-mass main jet 41. This is achieved by two insert sections 21, 22 and 31, 32.

Nach Fig. 2 sind beide Einlagenabschnitte 21 und 22 einer Einlage 19 konvex ausgebildet.2, both insert sections 21 and 22 of an insert 19 are convex.

Eine Stufe bzw. eine Einschnürung 23 entsteht durch den wesentlich dünneren Werkstoff des Einlagenabschnittes 21 und durch die aneinanderstossenden konvexen Einlagenabschnitte 21 und 22. Der Einlagenabschnitt 22 besteht z.B. aus Kupfer und/oder Tental. Der Einlagenabschnitt 21 besteht z.B. aus Nickel oder Aluminium. Die Hohlladung 20 weist die Länge 28 auf. Im übrigen besteht sie aus der Hülle 6, dem Sprengstoff 7, einem Konus 24, einem Verschlußdeckel 25, einer Verstärkerladung 26 und einem Körper 27 zur Detonationswellen-Lenkung.A step or constriction 23 is created by the substantially thinner material of the insert section 21 and by the abutting convex insert sections 21 and 22. The insert section 22 consists e.g. made of copper and / or tental. The insert section 21 consists e.g. made of nickel or aluminum. The shaped charge 20 has the length 28. Otherwise, it consists of the shell 6, the explosive 7, a cone 24, a sealing cap 25, an amplifier charge 26 and a body 27 for detonation wave guidance.

Der initiierte Sprengstoff 7 formt den Einlagenabschnitt 21 zu dem Vorstrahl 40 um, siehe Fig. 4. Zeitverzögert, dargestellt durch den Abstand 41, wird dann der Hauptstrahl 42 aus dem Einlagenabschnitt 22 gebildet. Der Vorstrahl 40 löst dann die Sperrwirkung einer nicht dargestellten aktiven Panzerung aus und eliminiert sie.The initiated explosive 7 forms the insert section 21 into the pre-jet 40, see FIG. 4. With a time delay, represented by the distance 41, the main jet 42 is then formed from the insert section 22. The pre-beam 40 then triggers the blocking effect of an active armor, not shown, and eliminates it.

Der Abstand 41 ist so bemessen, daß der Hauptstrahl 42 dann auf die Panzerung auftrifft, wenn ein Geschoßteil der Panzerplatten der aktiven Panzerung zur Ruhe gekommen ist. Der Hauptstrahl 42 durchschlägt dann sowohl die Panzerplatten der aktiven Panzerung als auch die Hauptpanzerung.The distance 41 is dimensioned such that the main beam 42 strikes the armor when a projectile part of the armor plates of the active armor has come to rest. The main beam 42 then passes through both the armor plates of the active armor and the main armor.

Nach Fig. 3 ist die zylindrische Hohlladung 30 mit einer einstückigen Einlage 33 z.B. aus Nickel mit den Einlageabschnitten 31 und 32, jedoch ohne Detonationswellen-Lenkung, ausgestattet. Die Einschnürung 23 ist gebildet durch den wesentlich dünneren Einlagenabschnitt 31 und durch die unterschiedlichen Winkel 34 und 35. Die Hohlladung 30 weist die Länge 36 auf. Die Wirkung der Hohlladung 30 entspricht der der Hohlladung 20.According to Fig. 3, the cylindrical shaped charge 30 with a one-piece insert 33 e.g. made of nickel with the insert sections 31 and 32, but without detonation wave steering. The constriction 23 is formed by the substantially thinner insert section 31 and by the different angles 34 and 35. The hollow charge 30 has the length 36. The effect of the shaped charge 30 corresponds to that of the shaped charge 20.

Die Einlagen 24 und 33 sind absichtlich mit einer Trennstelle in Form einer Einschnürung 23 auszubilden. Vorteilhaft ist die kurze und einfache Bauweise der Hohlladung, vor allem die Funktionssicherheit aufgrund einer einzigen Zündstelle und daß Vor- und Hauptstrahl sich auf der Ladungsachse bewegen, so daß bei einer geeigneten Auskleidung in Massivzielen der von der Vorladung erzeugte Krater von dem Hauptstrahl ohne nennenswerte Kraterwandverluste vertieft wird.The inserts 24 and 33 are deliberately designed with a separation point in the form of a constriction 23. The short and simple design of the shaped charge is advantageous, above all the functional reliability due to a single ignition point and that The pre-beam and the main beam move on the charge axis, so that with a suitable lining in solid targets, the crater generated by the pre-charge is deepened by the main beam without any significant crater wall losses.

Bisher wurden für die beiden Hohlladungs-Strahlen bzw. Partikel-Strahlen in konventioneller Technik zwei Hohlladungen in Tandemanordnung innerhalb eines Geschosses vorgesehen. Es ist klar, daß nicht nur der konstruktive Aufwand groß ist, sondern auch die Maßnahmen zur Koordination der beiden Zündstellen und die Maßnahmen zur gegenseitigen Verdämmung sehr aufwendig sind. Ein derart komplexer Aufwand beinhaltet auch relativ viele Fehlerquellen. Wesentlich ist auch die gegenüber der Hohlladung 2 wenigstens um 15% bis 35% kürzere Länge 28 bzw. 36 der erfindungsgemäßen Hohlladungen 20 und 30 bei wesentlich geringeren Mengen an Sprenstoff 7.So far, two shaped charges in tandem arrangement within a floor have been provided for the two shaped charge beams or particle beams in conventional technology. It is clear that not only the design effort is great, but also the measures for coordinating the two ignition points and the measures for mutual insulation are very complex. Such a complex effort also involves a relatively large number of sources of error. The length 28 or 36 of the shaped charges 20 and 30 according to the invention, which is at least 15% to 35% shorter than the shaped charge 2, is also essential with significantly smaller amounts of explosive 7.
