Abstract

Bei einem pyrotechnischen Zünder für ein Bomblet ist durch einen Übertragungsdetonator (20) die sichere Zündung eines Detonators (10), ausgehend von einem Verzögerungsdetonator (15) gewährleistet.In the case of a pyrotechnic detonator for a bomblet, the reliable ignition of a detonator (10), starting from a delay detonator (15), is ensured by a transmission detonator (20).

Description

Die Erfindung bezieht sich auf einen pyrotechnischen Zünder für Geschosse, Raketen, Bomblets und Minen nach dem Oberbegriff des Anspruches 1.The invention relates to a pyrotechnic detonator for projectiles, missiles, bomblets and mines according to the preamble of claim 1.

Bei einem Zünder für Bomblets nach der DE 35 24 080 Al ist in einem querbe­weglichen Schieber ein Detonator und ein Anzündsatz für einen gehäusefest angeordneten Verzögerungssatz vorgesehen. Durch die räumliche Trennung des Anzündsatzes von dem Verzögerungssatz kann es zu Störungen der Zündübertragung kommen, so daß der Detonator nicht gezündet wird. Dies hat dann bei einem weichen Zielaufprall zur Folge, daß durch die nicht in Aktion getretene Funktion des üblicherweise vorhandenen Aufschlagzünders der Detonator scharf bleibt und damit das Bomblet zu einem Blindgänger wird.In a detonator for bomblets according to DE 35 24 080 A1, a detonator and an ignition set for a deceleration set arranged in the housing are provided in a transverse slide. The spatial separation of the ignition charge from the delay set can lead to malfunctions in the ignition transmission, so that the detonator is not ignited. In the case of a soft target impact, this then has the consequence that the detonator remains in focus due to the function of the impact detonator, which is usually not present, and the bomblet thus becomes a dud.

Aufgabe der Erfindung ist es daher, eine sichere Anzündung des Verzögerungs­satzes zu erreichen.The object of the invention is therefore to achieve a reliable ignition of the delay set.

Diese Aufgabe wird entsprechend den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved in accordance with the characterizing features of claim 1.

Vorteilhafte Weiterbildungen der Erfindung gehen aus den Unteransprüchen her­vor.Advantageous developments of the invention emerge from the subclaims.

Durch die Erfindung wird vorteilhaft erreicht, daß bei verhältnismäßig keinem Bauvolumen die sichere Zündung des Detonators sowohl bei einem Geschoß oder Bomblet mit oder ohne Drall gewährleistet ist.It is advantageously achieved by the invention that with relatively no overall volume, the detonator is reliably ignited both on a projectile or bomblet with or without swirl.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird zusammen mit den erzielten Vorteilen beschrieben.An embodiment of the invention is shown in the drawing and is described together with the advantages achieved.

In einem Bombletgehäuse 1 mit einer Zündnadel 2 ist ein Schieber 3 in Zündstellung in bekannter Weise arretiert. Der Schieber 3 liegt in einer Führung 4 eines Körpers 5. Der Schieber 3 weist eine Feder 6, einen Gasentspannungsraum 9, einen Detonator 10 zur Zündung einer nicht dargestellten Sprengladung, drei parallele Bohrungen 8, 11, 12 und Kanalabschnitte 13, 14 auf.In a bomblet housing 1 with an ignition needle 2, a slide 3 is locked in the ignition position in a known manner. The slide 3 is located in a guide 4 of a body 5. The slide 3 has a spring 6, a gas expansion chamber 9, a detonator 10 for igniting an explosive charge, not shown, three parallel bores 8, 11, 12 and channel sections 13, 14.

Die Bohrung 12 liegt quer, d.h. tangential zum Detonator 10 und weist einen Verzögerungsdetonator 15, bestehend aus Anzündsatz 16, Verzögerungssatz 18 und Überzündsatz 19 in einem Röhrchen 7 auf. Der Anzündsatz 16 ist bereits, wie gezeichnet, in Reaktion.The bore 12 is transverse, i.e. tangential to the detonator 10 and has a delay detonator 15, consisting of ignition charge 16, delay charge 18 and overfire charge 19 in a tube 7. The ignition charge 16 is already, as drawn, in reaction.

In der Bohrung 11 ist ein Übertragungsdetonator 20 über eine bei 21 verstemmte Scheibe 22 befestigt. Eine Wand 23 trennt den Über­tragungsdetonator 20 vom Detonator 10.A transmission detonator 20 is fastened in the bore 11 via a disk 22 caulked at 21. A wall 23 separates the transfer detonator 20 from the detonator 10.

Eine strichpunktierte Linie 25 bezeichnet die speziell gesicherte Ausgangsstellung des Schiebers 3.A dash-dotted line 25 denotes the specially secured starting position of the slide 3.

Zur Funktion bei einem mit großer Drehzahl rotierenden Bomblet:To function with a bomblet rotating at high speed:

Der in bekannter Weise entriegelte Schieber 3 schlägt durch die Kraft der Feder 6 und aufgrund der Zentrifugalkräfte an dem Gehäuse 1 an und wird über einen bekannten Mechanismus in der gezeichneten Stellung verriegelt. Beim Aufschlag wird der Anzündsatz 16 durch die Zündnadel 2 gezündet. Ausgehend von dem Anzündsatz 16 erfolgt dann die Zündung der übrigen Sätze 18 und 19 und des Übertragungs­detonators 20. Dieser initiiert dann durch die Wand 23 hindurch den Detonator 10. Die sichere Zündung des Detonators 10 ist auch unter ungünstigen Bedingungen gegen. Damit werden Blindgänger vermieden.The slide 3 unlocked in a known manner strikes against the housing 1 by the force of the spring 6 and due to the centrifugal forces and is locked in the position shown by a known mechanism. When it hits the ignition charge 16 is ignited by the ignition needle 2. Starting from the ignition charge 16, the other sets 18 and 19 and the transmission detonator 20 are then ignited. This then initiates the detonator 10 through the wall 23. The reliable ignition of the detonator 10 is also prevented under unfavorable conditions. This prevents duds.

Dazu trägt auch der Kanalabschnitt 13 mit dem Entspannungsraum bei, der den bei der Zündung des Übertragungsdetonators 20 entstehenden Überdruck in das Innere des Gehäuses 1 ableitet. Der Detonator 10 bleibt daher in seiner vertikalen Zündwirkung voll funktionsfähig. Der Überzündsatz 19 zerstört dünne Strukturen und ist daher in der Lage den Übertragungsdetonator 20 durch die dünne Wand 30 hindurch sicher zu zünden. Die Existenz der Bohrung 14 ist daher keine Voraus­setzung.The channel section 13 also contributes to this with the relaxation space, which discharges the excess pressure which arises when the transmission detonator 20 is ignited into the interior of the housing 1. The detonator 10 therefore remains fully functional in its vertical ignition effect. The overfire charge 19 destroys thin structures and is therefore able to reliably ignite the transfer detonator 20 through the thin wall 30. The existence of the bore 14 is therefore not a requirement.

Liegt bei dem Bomblet bzw. an dem Zünder kein Drall von, so ist die Scharfstellung des Schiebers 3 allein durch die Feder 6 zu be­wirken.If there is no swirl in the bomblet or on the detonator, then the slider 3 is brought into focus solely by the spring 6.
