A hollow charge with a filling of explosives which surrounds an insert (3) which, in particular, is a pointed cone, the insert delimiting a hollow space, and with a priming fuse, an inert disc body (6) for forming an annular firing zone being provided between priming fuse and explosive filling. So that a reduced constructional height can be used, it is provided that the disc body consists of several layers (7, 8) of different thickness and sound velocity and carries on the side facing the priming fuse a further layer (9) in the form of an explosive film. <IMAGE>

Description

Die Erfindung betrifft eine Hohlladung nach dem Oberbegriff des Anspruchs 1.The invention relates to a shaped charge according to the preamble of claim 1.

Aus der US-PS 3,077,834 ist eine Hohlladung bekannt, die eine Spreng­stoffüllung aufweist, die eine Einlage umgibt, wobei die Einlage einen Hohlraum begrenzt, während auf der der Einlage abgewandten Seite der Sprengstoffüllung eine Übertragungsladung, die von einem Initialzünder gezündet wird, angeordnet ist. Bei einer gegebenen Hohlraumform und bei einem gegebenen Abstand des Hohlraumes vom Zünder liegt damit der Auf­treffwinkel des Detonationsstrahles fest. Will man die punktförmige Zün­dung durch eine ringförmige Zündung ersetzen, sind besondere Maßnahmen zu treffen. Hierzu ist es aus der DE-AS 11 42 537 bekannt, benachbart zu dem Initialzünder und mit Abstand zu der Spitze der Einlage eine inerte Scheibe vorzusehen, die abgesehen von der Stelle, an der sich der Ini­tialzünder befindet, von der Sprengstoffüllung umgeben ist. Die Spreng­stoffüllung benachbart zu der inerten Scheibe bildet die Übertragungsla­dung. Dieser Aufbau erfordert eine relativ große Bauhöhe.A hollow charge is known from US Pat. No. 3,077,834 which has an explosive filling which surrounds an insert, the insert delimiting a cavity, while a transfer charge which is ignited by an initial detonator is arranged on the side of the explosive filling which faces away from the insert. With a given cavity shape and with a given distance of the cavity from the detonator, the angle of incidence of the detonation beam is thus fixed. If you want to replace the punctiform ignition by an annular ignition, special measures have to be taken. For this purpose, it is known from DE-AS 11 42 537 to provide an inert disk adjacent to the initiator and at a distance from the tip of the insert, which, apart from the location at which the initiator is located, is surrounded by the explosive charge. The explosive charge adjacent to the inert disk forms the transfer charge. This structure requires a relatively large height.

Aufgabe der Erfindung ist es, eine Hohlladung nach dem Oberbegriff des Anspruchs 1 zu schaffen, die mit verringerter Bauhöhe auskommt.The object of the invention is to provide a shaped charge according to the preamble of claim 1, which manages with a reduced overall height.

Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved in accordance with the characterizing part of claim 1.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und dem Unteransprüchen zu entnehmen.Further refinements of the invention can be found in the following description and the subclaims.

Die Erfindung wird nachstehend anhand des in der beigefügten Abbildung dargestellten Ausführungsbeispiels näher erläutert, in der eine Hohlla­dung im Schnitt dargestellt ist.The invention is explained below with reference to the embodiment shown in the accompanying figure, in which a shaped charge is shown in section.

Die dargestellte rotationssymmetrische Hohlladung besitzt eine Hülse 1, beispielsweise aus Kunststoff oder dergleichen, zur Aufnahme einer Sprengstoffüllung 2, die eine spitzkegelige Einlage 3 umgibt, die einen Hohlraum 4 begrenzt. Die Einlage 3 kann aus einem für Hohlladungen übli­chen Material, beispielsweise Kupfer, Blei oder dergleichen bestehen. Die Sprengstoffüllung 2 besitzt stirnseitig eine Ausnehmung 5, in die ein Schichtkörper 6 eingesetzt ist, der aus mehreren Schichten 7, 8 aus einem inerten Material besteht. Die Schichten 7, 8 sind abwechselnd angeordnet, wobei die Schichten 7 aus dichterem Material und die Schichten 8 aus we­niger dichtem Material bestehen, so daß die Schallausbreitung in den Schichten 7, 8 mit unterschiedlicher Geschwindigkeit erfolgt. Die Schich­ten 7, 8 besitzen ferner unterschiedliche Stärken. Eine weitere Schicht 9 ist mit den Schichten 7, 8 zu dem Schichtkörper 6 verbunden und befindet sich an der Stirnseite der Sprengstoffüllung 2. Die Schicht 9 ist eine Sprengstoffolie. Die Sprengstoffüllung 2 ist ferner in ein Fußteil 10 eingesetzt, das eine Bohrung 11 zum Einsetzen eines (nicht dargestellten) Initialzünders aufweist. Benachbart zu der als Sprengstoffolie ausgebil­deten Schicht 9 ist die Ausnehmung 5 zum Außenrand der Sprenstoffüllung 2 hin abgeschrägt. Das Fußteil 10 liegt mit seiner Innenseite an der freien Seite der Schicht 9 an.The rotationally symmetrical shaped charge shown has a sleeve 1, for example made of plastic or the like, for receiving an explosive filling 2 which surrounds a tapered insert 3 which delimits a cavity 4. The insert 3 can consist of a material which is customary for shaped charges, for example copper, lead or the like. The explosive filling 2 has a recess 5 on the end face, into which a laminated body 6 is inserted, which consists of several layers 7, 8 made of an inert material. The layers 7, 8 are arranged alternately, the layers 7 being made of denser material and the layers 8 of less dense material, so that the sound propagation in the layers 7, 8 takes place at different speeds. The layers 7, 8 also have different strengths. Another layer 9 is connected to the layers 7, 8 to form the layer body 6 and is located on the front side of the explosive filling 2. The layer 9 is an explosive film. The explosive charge 2 is also inserted into a foot part 10 which has a bore 11 for inserting an initial detonator (not shown). Adjacent to the layer 9 designed as an explosive film, the recess 5 is chamfered towards the outer edge of the explosive filling 2. The inside of the foot part 10 lies against the free side of the layer 9.

Die aus Sprengstoffolie bestehende Schicht 9 erstreckt sich im wesentli­chen (bis auf den abgeschrägten Außenrand der Sprengstoffüllung 2) über die gesamte Stirnseite der Sprengstoffüllung 2, während die Schichten 7, 8 etwa halben Durchmesser im Vergleich zum Durchmesser der Sprengstoff­füllung 2 aufweisen. Der Scheibenkörper 6 ist mit relativ großem Abstand zu der Spitze der Einlage 3 angeordnet.The layer 9 consisting of explosive foil extends essentially (except for the bevelled outer edge of the explosive filling 2) over the entire front side of the explosive filling 2, while the layers 7, 8 have approximately half the diameter compared to the diameter of the explosive filling 2. The disc body 6 is arranged at a relatively large distance from the tip of the insert 3.

Der als Detonationswellenlenker dienende Scheibenkörper 6 bewirkt durch seinen Aufbau, daß die von der Sprengstoffolie 9 erzeugte Stoßwelle stark abgebaut wird, so daß im Zentrum der Sprengstoffüllung keine Initiierung erfolgt, vielmehr die Sprengstoffüllung 2 durch die Sprengstoffolie 9 nur ringförmig am Rand angefeuert wird. Die Zusammensetzung der Sprengstoff­folie 9 hängt von der zu initiierenden Sprengstoffüllung 2 und von der Stärke der Zündung des Initialzünders ab. Die Sprengstoffolie 9 ersetzt die sonst übliche Übertragungs- und Verteilerladung. Sie kann aus einem hochenergetischen, relativ empfindlichen Sprengstoff bestehen, der in eine Kunststoffmatrix eingebettet ist. Beispielsweise kann man bei einer 96mm-Hohlladung eine Sprengstoffolie 9 einer Stärke von 4 mm und einer Zusammensetzung von 85% PETN und 15% Kunststoffbinder bei einer Spreng­stoffüllung aus 85% RDX und 15% TNT verwenden. Hierbei kann das Verhält­nis der Länge (L) der Hohlladung zum Durchmesser (D) 1,3 betragen, wäh­rend bei konventionellen Hohlladungen dieses Verhältnis 2 beträgt.The serving as a detonation wave guide disc body 6 causes by its structure that the shock wave generated by the explosive film 9 is greatly reduced so that no initiation takes place in the center of the explosive charge, rather the explosive charge 2 is only fired in a ring at the edge by the explosive film 9. The composition of the explosive film 9 depends on the explosive filling 2 to be initiated and on the Strength of the ignition of the initial igniter. The explosive foil 9 replaces the otherwise usual transmission and distribution charge. It can consist of a high-energy, relatively sensitive explosive that is embedded in a plastic matrix. For example, an explosive foil 9 with a thickness of 4 mm and a composition of 85% PETN and 15% plastic binder can be used with an explosive filling of 85% RDX and 15% TNT for a 96 mm hollow charge. The ratio of the length (L) of the shaped charge to the diameter (D) can be 1.3, while in conventional shaped charges this ratio is 2.

Für die Schicht 7 aus dichterem Material empfiehlt sich ein Metall, beispielsweise Stahl. Als weniger dichtes Material für die Schicht 8 hat sich Kunststoff, beispielsweise Sili­konkautschuk, bewährt.A metal, for example steel, is recommended for the layer 7 made of denser material. Plastic, for example silicone rubber, has proven to be a less dense material for layer 8.
