Abstract

The projectile casing 10 of a shaped charge daughter projectile is designed from coiled wire 12 to form a closed wall 18 in such a way that adjacent wire windings 14 are connected to one another in common areas 16. A predeterminable number of wire turns 14 in the vicinity of the base 22 of a shaped charge insert 20 remains unconnected, so that an ignition spacer 26 results which is delimited on the front side by the last wire turn 14 l.

Description

Die Erfindung betrifft ein Hohlladungstochtergeschoß nach dem Oberbegriff des Patentanspruchs.The invention relates to a shaped charge daughter projectile according to the preamble of the claim.

Ein gattungsgleiches Hohlladungstochtergeschoß ist be­kannt aus der DE-PS 22 42 930. Es ist säulenartig stapelbar. Der Zündabstandshalter ist als Rohr ausgebil­det und gegen die Rückstellkraft einer gewendelten Druck­feder zum Einnehmen der raumsparenden Transportstellung außenseitig axial über die Geschoßhülle schiebbar. Das bekannte Hohlladungstochtergeschoß wird höchsten An­forderungen gerecht. Sein Aufbau aus zahlreichen Einzel­teilen ist jedoch nachteiligerweise aufwendig und be­lastet die Logistik.A hollow charge daughter projectile of the same type is known from DE-PS 22 42 930. It can be stacked like a column. The ignition spacer is designed as a tube and can be pushed axially on the outside against the restoring force of a coiled compression spring to take up the space-saving transport position on the projectile envelope. The well-known shaped charge subsidiary floor meets the highest requirements. Its construction from numerous individual parts is disadvantageously complex and puts a strain on logistics.

Der Erfindung liegt folglich die Aufgabe zugrunde, ein Hohlladungstochtergeschoß der eingangs genannten Gattung zu schaffen, welches zudem aus vergleichsweise weniger Einzelteilen besteht und somit eine vereinfachte Ferti­gung gestattet.The invention is therefore based on the object to provide a shaped charge daughter storey of the type mentioned, which also consists of comparatively fewer individual parts and thus allows simplified production.

Gelöst wird die Aufgabe nach der Lehre des Patentanspruchs mit den in dessen kennzeichnendem Teil angegebenen erfin­derischen Merkmalen.The object is achieved according to the teaching of the patent claim with the inventive features specified in its characterizing part.

Die Erfindung wird nachstehend anhand eines bevorzugten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below on the basis of a preferred exemplary embodiment.

Es zeigt jeweils

  • Fig. 1 einen Stapel aus zwei bekannten Hohlladungs­ tochtergeschossen im längsaxialen Schnitt,
  • Fig. 2 ein Hohlladungstochtergeschoß nach der Er­findung im seitlichen Aufriß in Transport­stellung und
  • Fig. 3 das Hohlladungstochtergeschoß nach Fig. 2 mit einer zur Verdeutlichung weggebrochenen Partie in Wirkstellung,
wobei in den Figuren 2 und 3 auf die Darstellung aller erfindungsunwesentlichen Einzelheiten verzichtet und in allen drei Figuren nach Möglichkeit jeweils überein­stimmende Bezugszeichen verwendet wurden.It shows each
  • Fig. 1 shows a stack of two known shaped charge daughter shot in longitudinal axial section,
  • Fig. 2 is a shaped charge projectile according to the invention in side elevation in the transport position and
  • 3 shows the shaped charge projectile according to FIG. 2 with a portion broken away for clarification in the operative position,
wherein in FIGS. 2 and 3 the representation of all details not essential to the invention has been dispensed with and in all three figures the same reference numerals have been used wherever possible.

Gemäß Fig. 1 bilden zwei bekannte Hohlladungstochterge­schosse 8.1 und 8.2 (letzteres ist strichpunktiert dar­gestellt und nicht vollständig mit Bezugszeichen ver­sehen) mit je einer Geschoßhülle 10 einen Stapel. Dabei ist ein Zündabstandsrohr 46 gegen die Rückstellkraft ei­ner gewendelten Druckfeder 48 zur raumsparenden Trans­portstellung rückwärts über die Geschoßhülle 10 gescho­ben. Hierdurch ergibt sich für das Hohlladungstochterge­schoß 8.2 unter Abzug der Länge eines Zündergehäuses 28, welches Aufnahme in dem Hohlladungstochtergeschoß 8.1 - teilweise im Hohlraum der Hohlladungseinlage 20 - findet, eine mit 36 bezeichnete Länge in Transportstel­lung. Am Zündergehäuse 28 ist ein Wickelleitwerk 44 an­geordnet, welches einfach und zudem raumsparend ist. Ei­ne Sprengladung 30 ist nur durch das betreffende Bezugs­zeichen angedeutet.1, two known shaped charge projectiles 8.1 and 8.2 (the latter is shown in dash-dot lines and not completely provided with reference numerals), each with a projectile casing 10, form a stack. An ignition spacer tube 46 is pushed backwards against the restoring force of a coiled compression spring 48 for space-saving transport position over the projectile casing 10. For the shaped charge daughter storey 8.2, deducting the length of an igniter housing 28, which is accommodated in the shaped charge daughter storey 8.1 - partially in the cavity of the shaped charge insert 20 -, this results in a length designated 36 in the transport position. A winding guide 44 is arranged on the igniter housing 28 and is simple and also space-saving. An explosive charge 30 is only indicated by the relevant reference number.

Auch das Hohlladungstochtergeschoß nach der Erfindung ist stapelbar; aus Gründen der Übersichtlichkeit sind aber aus der Fig. 1 bekannte Einzelheiten - beispiels­weise das Stabilisierungsleitwerk - nicht mehr gesondert dargestellt.The shaped charge daughter storey according to the invention is also stackable; for reasons of clarity, however, details known from FIG. 1 - for example the stabilizing tail - are no longer separate shown.

Gemäß den Figuren 2 und 3 sind einander benachbarte Win­dungen 14 eines gewendelten Drahtes 12, welcher vorzugs­weise rechteckigen Querschnitt aufweist, in nur angedeu­teten Bereichen 16 miteinander verbunden. Dies kann durch Schweißen, Löten oder Kleben geschehen. Hierdurch entsteht eine geschlossene Wand 18 der Geschoßhülle 10. Letztere ist in einem ebenfalls nur angedeuteten Bereich 50 mit dem Zündergehäuse 28 verbunden. Die geschlossene Wand 18 der Geschoßhülle 10 hat die Länge 40, wobei die vorderseitige Begrenzung im wesentlichen durch eine Basisebene 22 der Hohlladungseinlage 20 gegeben ist. Im Nachbarbereich 24 der Basisebene 22 sind die Draht­windungen 14 nicht mehr miteinander verbunden. Auf die­se Weise entsteht eine Druckfeder als Abstandshalter 26; dies geschieht bei einem einzigen Arbeitsgang und ohne zusätzliches Teil.According to FIGS. 2 and 3, adjacent turns 14 of a coiled wire 12, which preferably has a rectangular cross section, are connected to one another in only indicated areas 16. This can be done by welding, soldering or gluing. This creates a closed wall 18 of the projectile casing 10. The latter is connected to the igniter housing 28 in a region 50, which is also only indicated. The closed wall 18 of the projectile casing 10 has the length 40, the front-side limitation essentially being given by a base plane 22 of the shaped charge insert 20. In the neighboring area 24 of the base level 22, the wire windings 14 are no longer connected to one another. In this way, a compression spring is created as a spacer 26; this is done in a single operation and without an additional part.

Im zur Transportstellung zusammengedrückten Zustand weist der Abstandshalter 26 (siehe Fig. 2) eine nur geringe Länge 41 auf. Die letzte Drahtwindung 14 ℓ defi­niert die äußere Begrenzung des Abstandshalters 26. In Wirkstellung (siehe Fig. 3) beträgt die Länge 38, wobei zu der konstanten Länge 40 nun die gegenüber der Länge 41 größere Länge 42 hinzuzurechnen ist.In the compressed state for the transport position, the spacer 26 (see FIG. 2) has only a small length 41. The last wire winding 14 ℓ defines the outer boundary of the spacer 26. In the active position (see FIG. 3), the length is 38, with the length 42 which is greater than the length 41 now being added to the constant length 40.

Das Ausführungsbeispiel ist nur mit einer einzigen La­ge gewendelten Drahtes dargestellt. Es versteht sich, daß mehrere Drahtwendeln eng ineinander geschoben sein können, wobei aus Gründen der Platzersparnis die Aus­bildung des Zündabstandshalters 26 der außenliegenden Drahtwendel vorbehalten bleibt.The embodiment is shown only with a single layer of coiled wire. It goes without saying that a plurality of wire helices can be pushed tightly into one another, the formation of the ignition spacer 26 of the outer wire helix being reserved for reasons of space saving.
