Abstract

An electrical energy supply device (13) for spin-stabilised munition (11) is to be designed for functionally reliable starting of the energy supply with the onset of the reduction in spin. For this purpose, provision is made of a thermal battery (14) which can be initiated mechanically and whose firing needle (27) is accelerated by a force element (28), for example a biased spring (29) when it is released by a locking element (21). The locking element (21) is displaced in the centrifugal direction when a sampling opening (23) in the munition structure (19) is released, because the anti-spin vane (24), which is initially situated thereabove, was able to deploy once the munition (11) was in free flight. <IMAGE>

Description

Die Erfindung betrifft eine elektrische Energieversorgungseinrichtung gemäß dem Oberbegriff des Anspruches 1.The invention relates to an electrical energy supply device according to the preamble of claim 1.

Eine solche Vorrichtung ist aus der DE-PS 29 04 501 in der Form eines hohlzylindrischen, radial beanspruchten Piezogenerators bekannt. Insbesondere betrifft die Erfindung aber eine Energieversorgungsein­ richtung für drallstabilisiert verschossene und dann aerodynamisch abgebremste Sub-Munition, wie sie etwa aus Heft 9/1986 der Zeitschrift WEHRTECHNIK (Seite 47 links unten) bekannt ist.Such a device is from DE-PS 29 04 501 in the form of a hollow cylindrical, radially stressed piezo generator. In particular, the invention relates to a power supply direction for spin-stabilized shot and then aerodynamic decelerated sub-ammunition, such as from issue 9/1986 of the magazine WEHRTECHNIK (page 47 bottom left) is known.

Der Erfindung liegt die Aufgabe zugrunde, eine einfach montierbare aber hoch-funktionstüchtige Energieversorgungseinrichtung zu schaffen, die insbesondere auch nach Drall-Abbau über eine notwendige Funktions­ zeitspanne die für den Betrieb der Sensor- und Zündschaltungen er­ forderliche elektrische Energie bereitstellt.The invention is based, an easy to assemble the task but to create a highly functional energy supply facility, which in particular even after swirl reduction via a necessary function time period for the operation of the sensor and ignition circuits provides required electrical energy.

Diese Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst, daß die gattungsgemäße Energieversorgungseinrichtung gemäß dem Kenn­ zeichnungsteil des Anspruches 1 ausgelegt ist. According to the invention, this object is essentially achieved by that the generic power supply device according to the characteristic Drawing part of claim 1 is designed.  

Nach dieser Lösung wird auf die bewährte Technik der thermisch aktivier­ baren Batterien zurückgegriffen, bei denen mittels eines durch externe Initiierung gezündeten Brandsatzes durch thermoelektrische Reaktion oder infolge Verflüssigung eines Elektrolyten durch chemoelektrische Reaktion eine relativ hochbelastbare elektrische Spannungsquelle bereitgestellt wird. Eine solche thermoelektrische Batterie kann gemäß DE-OS 34 38 155 aufgebaut sein. Bevorzugt wird aber auf aktivier­ bare Thermalbatterien zurückgegriffen, wie sie etwa aus der DE-OS 26 09 562 bekannt oder von der Firma Eagle Picher als Thermalbatterien auf den Markt gebracht sind.After this solution the thermally activated technology is used rechargeable batteries, which are used by means of an external Initiation of ignited fire by thermoelectric reaction or due to the liquefaction of an electrolyte by chemoelectric Response a relatively heavy-duty electrical voltage source provided. Such a thermoelectric battery can be constructed according to DE-OS 34 38 155. But it is preferred to activate bare thermal batteries, such as those used in DE-OS 26 09 562 known or from the company Eagle Picher as thermal batteries are brought to the market.

Zusätzliche Alternativen und Weiterbildungen sowie weitere Merkmale und Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und, auch unter Berücksichtigung der Darlegungen in der Zusammen­ fassung, aus nachstehender Beschreibung eines in der Zeichnung unter Beschränkung auf das Wesentliche stark abstrahiert aber angenähert maßstabsgerecht vergrößert skizzierten bevorzugten Realisierungsbei­ spiels zur erfindungsgemäßen Lösung.Additional alternatives and further training as well as further features and advantages of the invention result from the further claims and, also taking into account the statements in the context version, from the description below one in the drawing below Restriction to the essentials is highly abstract but approximate Preferred implementation example outlined to scale game to the solution according to the invention.

Die einzige Figur der Zeichnung zeigt in abgebrochener Längsschnittdarstellung den Einbau einer Energieversorgungseinrichtung in eine Submunition.The only figure in the drawing shows in broken longitudinal section the installation of a Power supply device in a submunition.

Die Schnittdarstellung zeigt die Submunition 11 in der Nachbarschaft ihrer Zylinderwandung 12 bei nicht-aktiviertem Zustand ihrer Energie­ versorgungseinrichtung 13. Diese besteht aus einer Thermalbatterie 14 mit koaxial dazu separat vor ihrem Zündelement 15 angeordneter Aktivierungsvorrichtung 16. Die Batterie 14 und ihre Aktivierungs­ vorrichtung 16 sind mit ihrer Längsachse 17 parallel zur Längsachse der Munition 11, dieser Munitionsachse gegenüber aber zur Wandung 12 hin versetzt, in einen Hohlraum 18 in der Munitions-Struktur 19 neben der Sensor- und Sicherungseinrichtung 20 angeordnet. The sectional view shows the submunition 11 in the vicinity of its cylinder wall 12 when its energy supply device 13 is not activated. This consists of a thermal battery 14 with an activation device 16 arranged coaxially to it in front of its ignition element 15 . The battery 14 and its activation device 16 are arranged with their longitudinal axis 17 parallel to the longitudinal axis of the ammunition 11 , but offset against this ammunition axis towards the wall 12 , arranged in a cavity 18 in the ammunition structure 19 next to the sensor and security device 20 .

Die Funktion der Aktivierungsvorrichtung 16 ist zunächst mittels eines Arretiergliedes 21 blockiert, bei dem es sich, wie dargestellt, im einfachsten Falle um einen Abtast-Stift 22 handelt. Nach Verbringen der Munition 11, wenn diese also aus einem Rohr abgeschossen, aus einem Trägerkörper ausgeworfen oder aus einem Verbringungs-Verband gelöst ist, ist eine Abtastöffnung 23 vor dem Stift 22 freigegeben, die im zeichnerisch dargestellten Beispielsfalle noch durch einen an die Struktur 19 anliegenden Entdrallfügel 24 verdeckt ist, der von der Struktur-Wandung 12 nur und erst abheben kann, wenn die verbrachte Munition 11 im Freiflug rotiert. Aufgrund der dabei auf­ tretenden Zentrifugalkräfte kann der quer zur Munitions- und damit zur Drallachse verschiebbar gelagerte, die Öffnung 23 abtastende Arretierstift 22 sich durch die dann freigegebene Öffnung 23 radial nach außen verlagern (und in einer verlagerten Stellung festgehalten oder einfach ganz herausgeschleudert werden). Jedenfalls gibt dadurch der Stift 22, beispielsweise mit seinem Arretier-Ende 25, die Akti­ vierungsvorrichtung 16 frei, damit diese das Zündelement 15 initiieren und damit die Batterie 14 für die elektrische Leistungsversorgung in Betrieb setzen kann.The function of the activation device 16 is initially blocked by means of a locking member 21 , which, as shown, is a scanning pin 22 in the simplest case. After the ammunition 11 has been moved , that is to say when it has been fired from a tube, ejected from a carrier body or released from a transfer assembly, a scanning opening 23 is released in front of the pin 22 , which in the example shown in the drawing is still adjacent to the structure 19 Swirl blade 24 is covered, which can only lift off the structure wall 12 and only when the spent ammunition 11 rotates in free flight. Due to the centrifugal forces that occur, the locking pin 22 , which is displaceably mounted transversely to the ammunition axis and thus to the swirl axis and which scans the opening 23, can be displaced radially outward through the opening 23 then opened (and held in a displaced position or simply flung out completely). In any case, the pin 22 releases, for example with its locking end 25 , the activating device 16 so that it can initiate the ignition element 15 and thus activate the battery 14 for the electrical power supply.

Die Aktivierungsvorrichtung 16 besteht vorzugsweise aus einem Stempel 26 mit Anstichnadel 27 für Initiierung des Zündelementes 16 durch mechanische Impulsbeaufschlagung. Hierfür wird, bei vom Abtaststift 22 freigegebener Aktivierungsvorrichtung 16, der Stempel 26 bis zur Abbremsung durch das Zündelement 15 mittels eines Kraftelementes 28 vorgeschoben, bei dem es sich im dargestellten bevorzugten Reali­ sierungsfalle um eine vorgespannte Zylinderfeder 29 handelt, die im topfförmigen Hohlraum 30 des Stempels 26 von rückwärts eingreifend abgestützt und geführt ist. Der Hohlstempel 26 selbst erfährt vorzugs­ weise eine Längsführung parallel zur Drallachse der Munition 11 in einem Hohlzylinder 31, der an einer Außenseite einen Flansch 32 für die Montage in der Munitionsstruktur 19 wie auch für die radial orientierte Führung des Abtaststiftes 22 aufweist. The activation device 16 preferably consists of a stamp 26 with a piercing needle 27 for initiating the ignition element 16 by mechanical impulse application. For this purpose, when the activation device 16 is released by the scanning pin 22 , the plunger 26 is pushed until it is braked by the ignition element 15 by means of a force element 28 , which in the preferred embodiment shown is a prestressed cylinder spring 29 which is in the pot-shaped cavity 30 of the plunger 26 is supported and guided from the rear engaging. The hollow punch 26 itself preferably experiences a longitudinal guide parallel to the swirl axis of the ammunition 11 in a hollow cylinder 31 , which has a flange 32 on the outside for mounting in the ammunition structure 19 as well as for the radially oriented guide of the stylus 22 .

Dadurch ergibt sich auch eine besonders leichte Einbaumöglichkeit für die Aktivierungsvorrichtung 16 in den Montage-Hohlraum 18 hinein von einem benachbarten Bremsschirm-Packraum 33 her, mit Arretierung der gespannten Feder 29 durch den seitlich vor den Stempel 26 ge­ schobenen Stift 22, ehe die mit ihrem Zündelement 15 versehene Batterie 14 hinter der so gesicherten Aktivierungsvorrichtung 16 eingesetzt wird.This also results in a particularly easy installation option for the activation device 16 into the mounting cavity 18 from an adjacent brake screen packing space 33 , with the tensioned spring 29 being locked by the pin 22 which is pushed laterally in front of the punch 26 before the pin with its Ignition element 15 provided battery 14 is inserted behind the activation device 16 secured in this way.
