Abstract

Submunition (11) mit elektrischer Zündeinrichtung (15) weist infolge geringerer Komplexität bei preisgünstigerer Realisierbarkeit eine höhere Funktionssicherheit auf, wenn sie mit einem Inline-Sekundärsprengstoffzündmittel (18) samt elektrischem Energiespeicher (16) und zwischengeschaltetem Auslöse-Triggerelement (17) ausgestattet ist, während die elektrische Zündenergiequelle (13) und ein Wandler (22) für das Laden des Speichers (16) im Submunitions-Träger (12) angeordnet sind. Der Ladevorgang findet nur statt, wenn eine ebenfalls im Träger (12) untergebrachte Sicherungseinrichtung (14) umweltabhängig angesprochen hat.Submunition (11) with an electrical ignition device (15) has a higher level of functional reliability due to its lower complexity and less expensive feasibility if it is equipped with an inline secondary explosive device (18) including an electrical energy store (16) and an intermediate trigger element (17), while the electrical ignition energy source (13) and a converter (22) for loading the memory (16) are arranged in the submunition carrier (12). The charging process only takes place if a safety device (14), which is also accommodated in the carrier (12), has responded to the environment.

Description

Die Erfindung betrifft eine Submunition gemäß dem Oberbegriff des Anspruches 1.The invention relates to a submunition according to the preamble of claim 1.

Derartige Submunition ist in funktionellem Zusammenhang mit ihrer Zündeinrichtung üblicherweise mit einer vollständigen, also innerhalb der jeweiligen Submunition autark arbeitenden Sicherungseinrichtung ausgestattet, die eine Scharfstellung der Munition erst in Abhängigkeit vom Vorliegen bestimmter Umwelt-Kritierien (wie dem Erreichen einer Lauerstellung oder dem Freiflug nach Verlassen des Trägers) bewirkt.Such a submunition, in functional connection with its ignition device, is usually equipped with a complete safety device that works autonomously within the respective submunition, which only arms the ammunition depending on the presence of certain environmental criteria (such as reaching a lurking position or free flight after leaving the Carrier) causes.

Der Erfindung liegt die Aufgabe zugrunde, den apparativen Aufwand für die gesicherte Scharfstellung von Submunition zu verringern und dadurch gleichermaßen eine größere funktionelle Zuverlässigkeit wie auch preisgünstigere Möglichkeiten zur Funktionsprüfung und zum Austausch funktionswesentlicher Komponenten zu eröffnen.The invention has for its object to reduce the outlay on equipment for the secure focusing of submunition and thereby open up greater functional reliability as well as less expensive options for functional testing and for the replacement of essential components.

Diese Aufgabe wird erfindungsgemäß im wesentlichen dadurch gelöst, daß die gattungsgemäße Submunition gemäß dem Kennzeichnungsteil des Anspruches 1 ausgestattet ist.This object is essentially achieved in that the generic submunition is equipped according to the characterizing part of claim 1.

Diese Lösung beruht auf der Überlegung, daß es möglich ist, die Sicherungsfunktion für alle mittels eines Trägers verbrachte Sub­munitionen in eine einzige im Träger selbst untergebrachte Sicherungs­einrichtung zusammenzufassen, wenn auf eine Scharfstellung im Wege mechanischer Inline-Verlagerung eines Detonators in der Zündeinrichtung der jeweiligen Submunition verzichtet wird; was wiederum möglich ist, wenn die Funktion des Zündmittels (für das Initiieren der Gefechts­ladung) auf dem Einsatz unempfindlicher Sprengstoffmischungen, so­genannten Sekundär-Sprengstoffes beruht, der durch elektrisch hervorge­rufene mechanische Energien zündbar ist (vgl. US-PS 4 368 670 oder US-PS 4 602 565). Denn die millitärischen Sicherheitsvorschriften für Zünder (US-MIL-STD-1316C vom 15.02.1977 Abschnitt 4.3.3a; bzw. NATO-Stanag 3525 AA vom 25.01.1976 Abschnitt 5) erlauben die Reali­sierung einer Sicherungseinrichtung ohne mechanische Zündketten-Unter­brechung bei Einsatz des erwähnten, unempfindlichen Sekundär-Spreng­stoffes.This solution is based on the consideration that it is possible to combine the security function for all submunitions carried by means of a carrier into a single security device accommodated in the carrier itself, if it is activated by mechanical in-line displacement of a detonator in the ignition device the respective submunition is dispensed with; which in turn is possible if the function of the primer (for initiating the combat charge) is based on the use of insensitive explosive mixtures, so-called secondary explosives, which can be ignited by electrically induced mechanical energies (cf. US Pat. No. 4,368,670 or US Pat 4 602 565). Because the military safety regulations for detonators (US-MIL-STD-1316C from February 15, 1977 section 4.3.3a; or NATO Stanag 3525 AA from January 25, 1976 section 5) allow the implementation of a safety device without mechanical ignition chain interruption when using the mentioned, insensitive secondary explosive.

Nach der erfindungsgemäßen Lösung ist so nur eine einzige, zentrale Sicherungseinrichtung für alle mittels eines Trägers verbringbare Submunitionen, also für alle Zündeinrichtungen erforderlich, und diese eine, zentrale Sicherungseinrichtung kann im Träger selbst untergebracht werden, ist also unabhängig von der Bestückung des Trägers mit Submunition für Prüf- und Austauschzwecke leicht zugänglich; während die Submunition selbst von diesem konstruktiven und funktionellen Sicherungsaufwand entlastet ist, also nur noch mit den unbedingt notwendigen Teilen für die Funktion der Zündeinrichtung ausgestattet sein muß. Diese Vereinfachung der Ausstattung der Submunition bei zentraler Sicherungseinrichtung für die Speisung aller Submunitionen führt zu einer wesentlichen Vereinfachung, also preisgünstigeren Realisierbarkeit bei gesteigerter Funktionstüchtigkeit der Submunitionen.According to the solution according to the invention, only a single, central securing device is required for all submunitions that can be brought about by means of a carrier, that is to say for all ignition devices, and this one, central securing device can be accommodated in the carrier itself, so it is independent of the equipment of the carrier with submunition for Test and exchange purposes easily accessible; while the submunition itself is relieved of this constructive and functional security effort, so it only has to be equipped with the absolutely necessary parts for the function of the ignition device. This simplification of the equipment of the submunition in the case of a central safety device for the supply of all submunitions leads to a significant simplification, that is to say a more cost-effective implementation with increased functionality of the submunitions.

Dabei ist zu berücksichtigen, daß die kostenaufwendige und voluminöse Energiequelle sowie die funktionskritischen Sicherungsschalter pro Submunitionsträger nun nur einmal, nämlich im Träger, realisiert werden müssen, und daß die Umwelt-Entsicherungskriterien grundsätzlich funktionell leichter in den Träger, als in im Träger gelegene Sub­munitionen eingebracht werden können.It should be taken into account that the costly and voluminous energy source and the function-critical safety switches per submunition carrier now only have to be implemented once, namely in the carrier, and that the environmental safety criteria are functionally easier to introduce into the carrier than into submunitions located in the carrier can.

Dennoch ist keine komplizierte Nahtstelle zwischen Träger und Sub­munitionen erforderlich, weil eine einfache Aufreißbrücke im Zuge der Ladeleitung zwischen der Träger-Energiequelle und dem Submunitions-­Speicher genügt.However, no complicated interface between the carrier and submunitions is required, because a simple tear-open bridge in the course of the charging line between the carrier energy source and the submunition store is sufficient.

Für jede Submunition ist auch bei Einzeln-Handhabung volle Sicherheit gegeben, obgleich die individuelle Submunition nicht mit der voll­ständigen Sicherungseinrichtung ausgestattet ist. Denn nur die über die Aufreißbrücke aus dem Wandler der Trägers gewinnbare sehr hohe Ladespannung kann die notwendige Energie liefern, mit der der Speicher in dem Submunition auf den notwendigen Wert aufgeladen wird, mit dem das Sekundärsprengstoff-Zündmittel angesteuert werden kann. Die Stör-Umwelt, die bei der isolierten Handhabung der einzelnen Submunition vorliegt, liefert aber nicht die notwendige elektrische Spannung (in der Größenordnung von einigen tausend Volt) zum Initiieren des Zündmittels.For each submunition there is full security even when handled individually, although the individual submunition is not equipped with the complete safety device. This is because only the very high charging voltage that can be obtained from the transducer of the carrier via the tear-open bridge can deliver the necessary energy with which the storage in the submunition is charged to the necessary value with which the secondary explosive primer can be controlled. The interference environment, which is present in the isolated handling of the individual submunitions, does not, however, supply the necessary electrical voltage (in the order of a few thousand volts) to initiate the ignition means.

Wenn der Zeitpunkt für den Ausstoß der Submunition aus dem Träger außerhalb einer Vorfeld-Sicherheitsspanne liegt, kann auch das Vor­feld-Entsicherungskriterium in die Sicherungseinrichtung im Träger selbst verlagert werden, also auch insoweit eine Entlastung der Submunition stattfinden.If the time for the submunition to be ejected from the carrier lies outside an apron safety margin, the apron releasing criterion can also be relocated to the security device in the carrier itself, that is to say the submunition can be relieved to that extent.

Die erfindungsgemäß ausgestattete Submunition ist unempfindlich gegen mechanische Umwelt-Störeinflüsse, weil sie kein bewegliches Teil und insbesondere kein mechanisch verlagerbares Sicherungsteil mehr enthält. Ihre Struktur wird nicht mehr geschwächt, da die Ent­sicherungs-Umweltkriterien nur noch in den Träger selbst, aber nicht in seine Submunition eingebracht werden sollen, also z.B. keine Abtaststifte oder Windradgenerator-Schlitten, die aus der Submunition-Hülle austreten müßten, an der Submunition mehr erforderlich sind.The submunition equipped according to the invention is insensitive to mechanical environmental disturbances, because it no longer contains a moving part and in particular no mechanically displaceable securing part. Their structure is no longer weakened, since the safety releasing environmental criteria should only be introduced into the carrier itself, but not into its submunition, for example, no more stylus pens or wind turbine generator slides that would have to emerge from the submunition shell at the submunition required are.

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 Zusammen­fassung, aus nachstehender Beschreibung von in der Zeichnung unter Beschränkung auf das Wesentliche stark abstrahiert und nicht maß­stäblich nach Art von Blockschaltbildern skizzierten Ausführungs­beispielen zur erfindungsgemäßen Lösung. Es zeigt:

  • Fig. 1 die grundsätzliche Aufteilung zwischen einerseits Energiequelle und Sicherungsschaltern sowie anderer­seits den Zündeinrichtungen zwischen einem Sub­munitionsträger und mehreren darin enthaltenen Submunitionen und
  • Fig. 2 die funktionelle Aufteilung zwischen Submunition und Träger gemäß Fig. 1 in detaillierterer Dar­stellung insbesondere hinsichtlich der Entsicherungs­kriterien.
Additional alternatives and further developments as well as further features and advantages of the invention emerge from the further claims and, also taking into account the explanations in the summary, from the following description of the abstracted in the drawing, limited to the essentials, and not outlined to scale in the manner of block diagrams Exemplary embodiments of the solution according to the invention. It shows:
  • Fig. 1 shows the basic division between on the one hand energy source and fuse switches and on the other hand the ignition devices between a submunition carrier and several submunitions and contained therein
  • FIG. 2 shows the functional division between submunition and carrier according to FIG. 1 in a more detailed representation, in particular with regard to the unlocking criteria.

Bei jeder Submunition 11 kann es sich gleichermaßen um Abwurfmunition mit Aufschlagzünder (vgl. z.B. DE-OS 33 17 376), um gezielt gestartete Munition mit Annäherungs- oder Aufschlagzünder (vgl. z.B. DE-OS 33 29 700), um Suchzünder-Munition (vgl. z.B. US-PS 4 587 902) oder um Lenkmunition (vgl. z.B. das System MLRS III oder US-PS 4 522 356) handeln. Die Verbringung solcher Submunition 11 in die Start-­(Ausstoß- oder Abschuß-)Position kann etwa mittels unbemanter Flug­körper (Drohnen, Abstandswaffen-Dispenser, Geschossen oder Raketen) oder mittels in Lauerstellung ausgesetzter Starteinrichungen erfolgen, wobei es prinzipiell gleichgültig ist, ob der Träger 12 mit nur einer oder mit mehreren gleichzeitig oder gestaffelt zu aktivierenden Submunitionen 11 ausgestattet ist; grundsätzlich kann aber auch ein bemannter Träger 11 (beispielsweise ein Flugzeug oder ein Tauch­boot) vorgesehen sein, wenn durch entsprechende Vorfeld-Sicherungs­maßnahmen in der ausgegebenen Submunition 11 eine Träger-Gefährdung ausgeschlossen ist.Each submunition 11 can equally be launching ammunition with a detonator (see, for example, DE-OS 33 17 376), specifically launched ammunition with a proximity or detonator (see, for example, DE-OS 33 29 700), or detonator ammunition see, for example, US Pat. No. 4,587,902) or steering ammunition (see, for example, the MLRS III system or US Pat. No. 4,522,356). Such submunitions 11 can be brought into the start (ejection or launch) position, for example, by means of unmanned missiles (drones, ranged weapons dispensers, projectiles or missiles) or by means of launching devices which are in wait position, it being in principle irrelevant whether the carrier 12 is equipped with only one or with several submunitions 11 to be activated simultaneously or in stages; in principle can also a manned carrier 11 (for example, an aircraft or a submersible) can be provided if a suitable danger of apron security in the issued submunition 11 precludes a carrier hazard.

In der Prinzipskizze der Fig. 1 ist dargestellt, daß für eine Mehr­zahl an Submunitionen 11 nur eine einzige Energiequelle 13 (z.B. in der Form einer thermisch oder durch Umweltweinflüsse wie See­wasser aktivierbaren Batterie), nämlich außerhalb der Submunition 11 am Träger 12, vorgesehen ist. Auch die Sicherungseinrichtung 14 ist nur einmal, für alle mittels des Trägers 12 verbringbare Submunitionen 11 gemeinsam, im Träger 12 vorhanden. Jede im Träger 12 abschuß- oder abwurfbereit gehalterte Submunition 11 ist lediglich mit einer Zündeinrichtung 15 ausgestattet, enthaltend einen elek­trischen Ladungsspeicher 16 (den sogenannten Zündkondensator) und ein mechanisches oder elektrisches Triggerelement 17 (z.B. einen elektronisch ansteuerbaren Schalter wie einen Thyristor) in Serie mit einem Sekundärsprengstoff-Zündmittel 18. Dieses initiiert die Gefechtsladung 19, wenn der Zünder 20 - nach verlassen des Submunitions-­Trägers 12 - anspricht, also das Triggerelement 17 durchschaltet; sofern der Speicher 16 vor einem Trennen der Submunition 11 vom Träger 12 geladen wurde, weil Umwelt-Sensoren 21 ihre Entsicherungs­kritierien an die Sicherungseinrichtung 14 geliefert haben, die elektrisch zwischen der Energiequelle 13 und den Speichern 16 liegt.1 shows that for a plurality of submunitions 11 only a single energy source 13 (e.g. in the form of a battery which can be activated thermally or by environmental wine flows such as sea water), namely outside the submunition 11 on the carrier 12, is provided. The safety device 14 is also present only once in the carrier 12, for all submunitions 11 that can be brought together by means of the carrier 12. Each submunition 11 held ready for firing or launching in the carrier 12 is only equipped with an ignition device 15, comprising an electrical charge store 16 (the so-called ignition capacitor) and a mechanical or electrical trigger element 17 (for example an electronically controllable switch such as a thyristor) in series with one Secondary explosives detonator 18. This initiates the combat charge 19 when the detonator 20 responds - after leaving the submunition carrier 12 - that is, switches the trigger element 17 on; if the memory 16 was loaded from the carrier 12 before the submunition 11 was disconnected because environmental sensors 21 have delivered their unlocking criteria to the safety device 14, which is electrically located between the energy source 13 and the memories 16.

Nach Ansprechen der Sensoren 21 wird also der Speicher 16, gegebenen­falls über einen Wandler 22 zur Strom- oder Spannungsanpassung, über eine Abreißbrücke 23 zwischen Träger 12 und jeweiliger Sub­munition 11 geladen, die getrennt wird, wenn daraufhin aus einem (in der Zeichnung nicht berücksichtigten) Steuergerät die jeweilige Ausstoßvorrichtung 24 zum Abwurf bzw. Start der Submunitionen 11 aus ihrem Träger 12 initiiert wird.After the sensors 21 have responded, the memory 16 is loaded, if necessary via a converter 22 for current or voltage adjustment, via a tear-off bridge 23 between the carrier 12 and the respective submunition 11, which is separated if there is then a (not shown in the drawing) Control unit, the respective ejection device 24 for launching or starting the submunitions 11 from its carrier 12 is initiated.

Das in Fig. 2 skizzierte Realisierungsbeispiel bezieht sich vorzugs­weise auf einen Anwendungsfall gemäß der erwähnten DE-OS 33 29 700, bei der pro Träger 12 nur eine einzige Submunition 11 vorgesehen ist. Als Umwelt-Entsicherungssensoren 21 sind ein Abtaster 21.1 (zur Detektion des Verlassens eines Werker-Rohres, mit dem der Träger 12 samt seiner Submunition 11 verbracht wurde) und eine Druckmembran 21.2 (die erst nach Absinken auf eine hinreichende Wassertiefe an­spricht) vorgesehen; stattdessen oder zusätzlich können andersartig wirkende Sensoren 21 wie etwa ein Aufsetzsensor (in der Zeichnung nicht berücksichtigt) vorgesehen sein, der auf Erreichen einer Lauer­stellung am Gewässergrund anspricht. Die von den Sensoren 21 ge­lieferten Informationen können mechanisch (z.B. durch Gestänge-Ver­schiebung) oder elektrisch (z.B. als Spannungspegel) übermittelt werden, die in mechanischen, mechanisch-elektrischen oder elektrischen Umsetzern 25 zu für die Beeinflussung der Sicherungseinrichtung 14 geeigneten Entsicherungsinformationen 26 verarbeitet werden.The implementation example sketched in FIG. 2 preferably relates to an application according to the aforementioned DE-OS 33 29 700, in which only a single submunition 11 is provided per carrier 12. A environmental sensor 21 is provided with a scanner 21.1 (for detecting the leaving of a worker tube with which the carrier 12 and its submunition 11 were brought) and a pressure membrane 21.2 (which only responds to a sufficient water depth after it has sunk); instead, or in addition, sensors 21 acting in a different way, such as a touchdown sensor (not taken into account in the drawing), can be provided, which responds when a lurking position is reached on the water bed. The information provided by the sensors 21 can be transmitted mechanically (e.g. by shifting the linkage) or electrically (e.g. as a voltage level), which is processed in mechanical, mechanical-electrical or electrical converters 25 to unlocking information 26 suitable for influencing the securing device 14.

In der Sicherungseinrichtung 14 ist in der Regel jedem Sensor 21 ein (elektrischer oder mechanischer) Schalter 27 zugeordnet, die funktionell eine UND-Verknüpfung realisieren, also beispielsweise wie dargestellt in Serie geschaltet sind. Wenigstens einer der Schalter 27 wird von der Entsicherungsinformation 26 nicht unmittelbar, sondern über ein Verzögerungsglied 28 zur Vorfeldsicherung angesteuert. Dieses kann aus der zentralen elektrischen Energiequelle 13 betrieben werden; oder es ist mit (in der Zeichnung nicht berücksichtigt) einer eigenen Energiequelle ausgestattet, beispielsweise mit einem Federspeicher mit Falle einer Realisierung als mechanisches Uhrwerk.As a rule, each sensor 21 is assigned an (electrical or mechanical) switch 27 in the safety device 14, which functionally implement an AND operation, for example, as shown, are connected in series. At least one of the switches 27 is actuated by the unlocking information 26 not directly, but via a delay element 28 for apron security. This can be operated from the central electrical energy source 13; or it is equipped with its own energy source (not taken into account in the drawing), for example with a spring accumulator if it is implemented as a mechanical clockwork.

Wenn, außer dem direkt mit einer Entsicherungsinformation 26 beauf­schlagten Schalter 27, nach Ablauf der Vorfeldsicherungs-Verzögerungs­zeitspanne auch der weitere Schalter 27 angesteuert ist, ist der Leistungskreis aus der Energiequelle 13 über den Wandler 22 und die Abreißbrücke 23 geschlossen, und in der Zündeinrichtung 15 wird der Speicher 16 geladen. Nun kann die Ausstoßvorrichtung 24 initiiert und mit Abheben der Submunition 11 aus dem Halterungsrohr 29 des Trägers 12 die Brücke 23 aufgerissen werden, weil die elektrische Zündenergie in der nun gestarteten Submunition 11 zur Verfügung steht, die Submunition 11 also scharf ist. Bei Ansprechen des Gefechts­kopf-Zünders 20 (etwa aufgrund Zielannäherung oder Zielaufschlags) und somit durchgeschaltetem Triggerelement 17 wird die Energie aus dem Speicher 16 in das Sekundärsprengstoff-Zündmittel 18 entladen, worüber - ohne das Erfordernis eines zuvor mechanisch in Linie zu schwenkenden Detonators - unmittelbar die Gefechtsladung 19 initiiert wird.If, in addition to the switch 27 directly loaded with an unlocking information 26, the further switch 27 is also activated after the apron protection delay time period has expired, the power circuit from the energy source 13 is closed via the converter 22 and the tear-off bridge 23, and in the ignition device 15 the memory 16 loaded. Now the ejection device 24 can be initiated and the bridge 23 can be torn open when the submunition 11 is lifted out of the holder tube 29 of the carrier 12, because the electrical ignition energy is available in the submunition 11 that has now started, ie the submunition 11 is armed. When the warhead detonator 20 responds (for example due to target approach or target impact) and the trigger element 17 is thus switched through, the energy is discharged from the memory 16 into the secondary explosive primer 18, via which - without the need for a detonator which has to be pivoted mechanically in line beforehand - the Battle Charge 19 is initiated.

In Fig. 2 der Zeichnung ist zur Vereinfachung der Darstellung der Arbeitsweise des Zünders 20 offengelassen. Falls für seine Funktion elektrische Energie erforderlich ist, kann vorgesehen sein (in der Zeichnung nicht berücksichtigt), den Zünder zusätzlich an den Speicher 16 anzuschließen, oder aber ihn mit eigenem Speicher auszustatten, der entweder über die Aufreißbrücke 23 parallel zum Zündspeicher 16 aus dem Wandler 22 oder aber über eine weitere Brücke direkt aus der Energiequelle 13 gespeist wird. Bei den Brücken 23 kann es sich um ohmsche Verbindungen (Steckkontakt, Reißdraht) oder um andere Koppelelemente (z.B. optronische oder induktive Kopplungen) handeln.2 of the drawing is left open to simplify the illustration of the operation of the igniter 20. If electrical energy is required for its function, provision can be made (not taken into account in the drawing) to additionally connect the detonator to the memory 16, or else to equip it with its own memory, which is either parallel to the ignition memory 16 from the converter via the tear-open bridge 23 22 or is fed directly from the energy source 13 via a further bridge. The bridges 23 can be ohmic connections (plug contact, tear wire) or other coupling elements (e.g. optronic or inductive couplings).
