Description

Die Erfindung betrifft einen Wirkkörper zur wahlweise detonativen, deflagrativen oder detonativen und deflagrativen Umsetzung einer Sprengstoffwirkmasse. Bei dem Wirkkörper kann es sich beispielsweise um einen Gefechtskopf handeln. Bei einem Einsatz von Gefechtsköpfen in urbaner Umgebung besteht häufig das Problem, dass sich in unmittelbarer Nähe des Ziels zivile oder andere Einrichtungen befinden, die nicht beschädigt werden sollen. Gefechtsköpfe sollen daher in ihrer Leistung so einstellbar sein, dass sie möglichst nur das gewünschte Ziel zerstören und möglichst wenig Kollateralschäden anrichten.The invention relates to an active body for either detonative, deflagrative or detonative and deflagrative implementation of an explosive active material. The active body may be, for example, a warhead. When using warheads in an urban environment, there is often the problem that there are civilian or other facilities in the immediate vicinity of the target that should not be damaged. Warrior heads should therefore be so adjustable in their performance that they only destroy the desired target and cause as little collateral damage as possible.

Zur Bestimmung der Empfindlichkeit eines Sprengstoffs wird häufig ein sogenannter GAP-Test durchgeführt. Dabei wird zwischen den zu untersuchenden Sprengstoff und eine durch einen Detonator zu zündende Verstärkungsladung eine im Allgemeinen aus Polymethylmethacrylat (PMMA) bestehende Barriereschicht positioniert. Die Verstärkungsladung wird dann zur Detonation gebracht. Dadurch wird eine Druckwelle in die Schicht eingekoppelt, die beim Durchlaufen der Schicht gedämpft wird, bevor sie auf den Sprengstoff trifft. Der GAP-Test wird mit unterschiedlichen Schichtdicken der Barriereschicht durchgeführt. Dabei werden die größte Schichtdicke, bei der der Sprengstoff gerade noch detoniert, und die geringste Schichtdicke, bei der gerade noch keine Detonation stattfindet, als Maß für die Empfindlichkeit des Sprengstoffs bestimmt.To determine the sensitivity of an explosive, a so-called GAP test is often carried out. In this case, a generally made of polymethyl methacrylate (PMMA) existing barrier layer is positioned between the explosives to be examined and a to be fired by a detonator boost. The boost charge is then detonated. As a result, a pressure wave is coupled into the layer, which is attenuated as it passes through the layer before it hits the explosive. The GAP test is carried out with different layer thicknesses of the barrier layer. In this case, the largest layer thickness at which the explosive is just detonated, and the lowest layer thickness at which just no detonation takes place, determined as a measure of the sensitivity of the explosive.

Aus der DE 199 61 204 C2 , welche den Ausgangspunkt für den Oberbegriff des Anspruchs 1 und für Verfahrensanspruch 4 darstellt, ist eine Zündeinrichtung für einen Gefechtskopf mit einer Sprengladung mit einer ersten Zündkette mit Verstärkerladung zur detonativen Initiierung und einer zweiten Zündkette mit Verstärkerladung zur deflagrativen Initiierung bekannt, wobei die Zeitverzögerung (Δt) zwischen den Auslösezeitpunkten beider Zündketten einstellbar ist. Liegen sich die beiden Zündketten bezüglich der Längsachse der Sprengladung gegenüber, so ist mittels geeigneter Wahl der beiden Zündzeitpunkte die beliebige Einstellung des deflagrierenden Anteils der Sprengladung zwischen 0 und 100 % erzielbar. Die Verstärkerladung der zweiten Zündkette kann als Hohlladung ausgebildet sein. Diese erzeugt bei Detonation einen in die Sprengladung eindringenden Stachel, der eine Deflagration der Sprengladung auslösen kann. Um die Hohlladung an das zur Auslösung einer Deflagration erforderliche Energieniveau anzupassen, können Metallplatten oder ähnlich wirkende Materialien vorgeschaltet werden, um die Stachelwirkung so zu reduzieren, dass in der Sprengladung nur eine Deflagration ausgelöst wird. Die zweite Verstärkerladung wirkt aber trotz der vorgeschalteten Materialien bei ihrer Detonation direkt auf die Sprengladung ein.From the DE 199 61 204 C2 , which is the starting point for the preamble of claim 1 and for method claim 4, an ignition device for a warhead with an explosive charge with a first firing chain with detonator charge for detonating initiation and a second firing chain with boost charge for deflagrativen initiation is known, the time delay (.DELTA.t ) between the triggering times both ignition chains is adjustable. If the two ignition chains lie opposite one another with respect to the longitudinal axis of the explosive charge, the arbitrary adjustment of the deflagrating portion of the explosive charge between 0 and 100% can be achieved by a suitable choice of the two ignition times. The booster charge of the second ignition chain may be formed as a shaped charge. This generates a detonation penetrating into the explosive charge sting, which can cause a deflagration of the explosive charge. In order to adapt the shaped charge to the energy level required to trigger a deflagration, metal plates or similar materials can be connected upstream in order to reduce the spiked effect so that only a deflagration is triggered in the explosive charge. However, the second amplifier charge acts directly on the explosive charge despite the upstream materials in their detonation.

Aus der DE 100 15 070 A1 ist eine Sprengladung für einen Gefechtskopf bekannt, der neben der Zündkette zur detonativen Initiierung der Sprengladung eine weitere Zündkette zur deflagrativen Initiierung aufweist. Dabei ist die Sprengladung in axialer Richtung derart geschichtet, dass auf eine erste, dritte, usw. detonativ umsetzbare Sprengstoffschicht jeweils eine zweite, vierte, usw. deflagrativ umsetzbare oder inerte Schicht folgt. Durch die entsprechende Wahl von detonativ oder deflagrativ umsetzbaren Sprengstoffen sowie inerten Materialien für die verschiedenen Schichten läuft die gezielt eingeleitete Deflagration kontrolliert ab und die Wahrscheinlichkeit des Übergangs einer Deflagration in eine Detonation wird weitestgehend unterdrückt.From the DE 100 15 070 A1 is an explosive charge for a warhead known, in addition to the detonating chain for detonative initiation of the explosive charge has another detonation chain for deflagrativen initiation. In this case, the explosive charge is layered in the axial direction such that a first, third, etc. detonatively convertible explosive layer is followed by a second, fourth, etc. deflagratively convertible or inert layer. Through the appropriate choice of detonative or deflagrative convertible explosives and inert materials for the different layers, the deliberately initiated deflagration is controlled and the probability of the transition of a deflagration into a detonation is largely suppressed.

Aus der DE 10 2007 054 382 A1 ist eine Munition großer Reichweite mit einer Zündkette zur letal wirksamen Selbstzerlegung bekannt, die eine De-Letalisierungseinrichtung aufweist, die zur Reduktion der Letalwirkung oder zur De-Letalisierung der Munition vorgesehen ist. Die De-Letalisierungseinrichtung ist mittels einer Aktivierungseinrichtung nach dem Abschluss der Munition in Abhängigkeit einer geänderten Lagebeurteilung aktivierbar. Die Munition kann einen langen Wuchtpfeil aufweisen, der zur Unterteilung in kürzere Wuchtpfeile mit Sollbruchstellen ausgebildet ist und zugehörige Sprengladungen besitzt.From the DE 10 2007 054 382 A1 For example, a long-range munition with a detonating chain for lethal self-decomposition is known, which has a de-lethalization device designed to reduce the lethal effect or de-mortalize the munition. The de-Letalisierungseinrichtung can be activated by means of an activation device after completion of the ammunition in response to a changed situation assessment. The ammunition may have a long balancing arrow, which is designed to subdivide into shorter balancing arrows with predetermined breaking points and has associated explosive charges.

Aufgabe der vorliegenden Erfindung ist es, einen alternativen Wirkkörper anzugeben, der im Falle eines Missionsabbruchs zur Vermeidung von Schäden im ursprünglichen Zielbereich zerstört werden kann oder dessen Wirkung skalierbar ist. Weiterhin soll ein Verfahren zur Umsetzung einer Sprengstoffwirkmasse in dem Wirkkörper angegeben werden, welches eine Wahl oder Skalierung der Wirkung der Umsetzung ermöglicht.Object of the present invention is to provide an alternative active body, which can be destroyed in the event of a mission abort to avoid damage in the original target area or its effect is scalable. Furthermore, a method for implementing an explosive active mass in the active body is to be specified, which allows a choice or scaling of the effect of the reaction.

Die Aufgabe wird durch die Merkmale der Patentansprüche 1 und 4 gelöst. Zweckmäßige Ausgestaltungen ergeben sich aus den Merkmalen der Patentansprüche 2 und 3.The object is solved by the features of claims 1 and 4. Advantageous embodiments will become apparent from the features of claims 2 and 3.

Erfindungsgemäß ist ein Wirkkörper zur wahlweise detonativen, deflagrativen oder detonativen und deflagrativen Umsetzung einer Sprengstoffwirkmasse vorgesehen. Durch die Wahl der Umsetzung kann die Sprengwirkung der Sprengstoffwirkmasse skaliert werden. Bei einer ausschließlich detonativen Umsetzung beträgt die Sprengwirkung 100 %, bei einer ausschließlich deflagrativen Umsetzung beträgt die Sprengwirkung 0 % und bei einer detonativen und deflagrativen Umsetzung ist die Sprengwirkung umso größer, je größer der Anteil der detonativ umgesetzten Sprengstoffwirkmasse ist.According to the invention, an active body is provided for optionally detonative, deflagrative or detonative and deflagrative conversion of an explosive active mass. By choosing the implementation, the explosive effect of the explosive active mass can be scaled. In an exclusively detonative implementation, the explosive effect is 100%, in an exclusively deflagrativen implementation the explosive effect is 0% and in a detonative and deflagrativen implementation, the explosive effect is greater, the greater the proportion of detonatively reacted explosive active material.

Der Wirkkörper umfasst die Sprengstoffwirkmasse, eine die Sprengstoffwirkmasse umgebende und an der Sprengstoffwirkmasse anliegende Wirkkörperhülle, eine erste Zündkette mit einer ersten Verstärkungsladung zur Auslösung der detonativen Umsetzung, eine Wirkladung zur Auslösung der deflagrativen Umsetzung und mindestens eine zweite Zündkette mit einer zweiten Verstärkungsladung zur Zündung der Wirkladung. Die Wirkladung ist Bestandteil einer auf einer Außenseite der Wirkkörperhülle angeordneten Schneidladung zum Durchtrennen der Wirkkörperhülle und dabei erfolgendem Einkoppeln einer Druckwelle in die Sprengstoffwirkmasse. Das Anliegen der Wirkkörperhülle an der Sprengstoffwirkmasse kann dabei ein direktes Anliegen oder indirektes Anliegen, beispielsweise über eine Zwischenlage aus Kunststoff, sein. Wesentlich ist dabei lediglich, dass die Druckwelle von der Wirkkörperhülle auf die Sprengstoffwirkmasse übertragen werden kann.The active body comprises the explosive active mass, an active explosive shell surrounding the explosive active mass and applied to the explosive active mass, a first firing chain with a first boost charge for triggering the detonative conversion, a dynamic charge for triggering the deflagrative reaction and at least one second firing chain with a second boost charge for firing the effective charge , The active charge is part of a arranged on an outer side of the active body shell cutting charge for severing the active body shell and thereby successive coupling a pressure wave in the explosive active mass. The concerns of the active body shell of the explosive active mass may be a direct concern or indirect concern, for example via an intermediate layer of plastic. It is essential only that the pressure wave from the active body shell can be transferred to the explosives active mass.

Bei der Schneidladung handelt es sich um eine aus dem Stand der Technik bekannte übliche Schneidladung, wie sie zum Durchschneiden von Stahl oder Stahlbeton verwendet wird. Bei dem erfindungsgemäßen Wirkkörper ist diese so bemessen, dass das Energieniveau der in die Sprengstoffwirkmasse eingekoppelten Druckwelle lediglich zur deflagrativen Umsetzung der Sprengstoffwirkmasse ausreicht. Bei einer deflagrativen Umsetzung besteht jedoch stets die Gefahr, dass diese in eine hier ungewollte detonative Umsetzung übergeht. Durch das Durchtrennen der Wirkkörperhülle wird dieses Risiko deutlich verringert, weil es dadurch bei der Umsetzung der Sprengstoffwirkmasse zu einer Druckentlastung kommt. Dadurch und durch das Einkoppeln der Druckwelle in die Sprengstoffwirkmasse kann eine lediglich deflagrative und nicht detonative Umsetzung sehr zuverlässig und mit verhältnismäßig geringem Aufwand sichergestellt werden.The cutting charge is a conventional cutting charge known from the prior art, as used for cutting through steel or reinforced concrete. In the case of the active body according to the invention, this is dimensioned such that the energy level of the pressure wave coupled into the explosive active mass is sufficient only for the deflagrative conversion of the explosive active mass. In a deflagrative implementation, however, there is always the danger that this transitions into an unintentional detonation here. By cutting through the active body shell this risk is significantly reduced, because it comes in the implementation of the explosive active mass to a pressure relief. As a result, and by the coupling of the pressure wave in the explosive active mass one can only deflagrative and non-detonative implementation can be ensured very reliably and with relatively little effort.

Weiterhin ermöglicht der erfindungsgemäße Wirkkörper die deflagrative Umsetzung der Sprengstoffwirkmasse innerhalb sehr kurzer Zeit in einen verhältnismäßig großen Bereich der Sprengstoffwirkmasse einzuleiten und damit die gesamte Sprengstoffwirkmasse schnell deflagrativ umzusetzen. Dadurch ist es möglich, im Falle eines gewünschten Missionsabbruchs einen Gefechtskopf bis kurz vor dessen geplanter Detonation unter Vermeidung von Schäden im ursprünglichen Zielbereich zu zerstören. Weiterhin ist es damit möglich, die Sprengwirkung des Wirkkörpers so zu skalieren, dass lediglich die gewünschte Zerstörungswirkung und keine oder nur geringe Kollateralschäden eintreten.Furthermore, the active body according to the invention makes it possible to initiate the deflagrative reaction of the explosive active material within a very short time in a relatively large area of the explosive active mass and thus implement the entire explosive active mass quickly deflagratively. This makes it possible, in the event of a desired mission abort, to destroy a warhead until shortly before its planned detonation while avoiding damage in the original target area. Furthermore, it is thus possible to scale the explosive effect of the active body so that only the desired destructive effect and no or only minor collateral damage occur.

Bei einer Ausgestaltung des erfindungsgemäßen Wirkkörpers ist die Schneidladung parallel zu einer Wirkkörperachse oder entlang eines Umfangs des Wirkkörpers angeordnet. Beide Anordnungen erlauben eine unmittelbare Druckentlastung bei der deflagrativen Umsetzung der Sprengstoffwirkmasse.In one embodiment of the active body according to the invention, the cutting charge is arranged parallel to a body axis or along a circumference of the active body. Both arrangements allow an immediate pressure relief in the deflagrative implementation of the explosive active mass.

Der Wirkkörper kann ein Mittel umfassen, welches eine gleichzeitige oder zeitlich versetzte Zündung der ersten und der zweiten Verstärkungsladung ermöglicht. Die zweite Verstärkungsladung kann dabei vor oder nach der ersten Verstärkungsladung gezündet werden. Bei der Bemessung der zeitlichen Verzögerung sind jeweils die Geschwindigkeiten der deflagrativen und der detonativen Umsetzung der Sprengstoffwirkmasse zu berücksichtigen. Dadurch kann die für die detonative Umsetzung zur Verfügung stehende Menge der Sprengstoffwirkmasse festgelegt und damit die Sprengwirkung des Wirkkörpers skaliert werden.The active body may comprise a means which allows a simultaneous or staggered ignition of the first and the second boost charge. The second boost charge can be ignited before or after the first boost charge. When calculating the time delay, the speeds of the deflagrative and detonative implementation of the explosive active mass must be taken into account. As a result, the amount of explosive active mass available for the detonative conversion can be determined, and thus the explosive effect of the active body can be scaled.

Die Erfindung betrifft weiterhin ein Verfahren zur wahlweise detonativen, deflagrativen oder detonativen und deflagrativen Umsetzung einer Sprengstoffwirkmasse in einem erfindungsgemäßen Wirkkörper, wobei die detonative Umsetzung durch Zünden der ersten Verstärkungsladung und die deflagrative Umsetzung durch Zünden der Wirkladung und ein dadurch erfolgendes Einleiten einer Druckwelle in die Sprengstoffmasse bewirkt wird, wobei die Druckwelle beim Durchtrennen der Wirkkörperhülle mittels der Schneidladung entsteht. Das Einleiten der Druckwelle ermöglicht eine sehr genaue Einstellung der auf die Sprengstoffwirkmasse zu übertragenden Energie, so dass dadurch sehr zuverlässig eine nur deflagrativ und nicht detonativ erfolgende Umsetzung der Wirkmasse eingeleitet werden kann.The invention further relates to a method for selectively detonative, deflagrative or detonative and deflagrative implementation of an explosive active material in a body of the invention, wherein the detonative reaction by igniting the first boost charge and the deflagrative reaction by igniting the active charge and thereby taking place a pressure wave in the explosive mass is effected, wherein the pressure wave arises when cutting the active body shell by means of the cutting charge. The introduction of the pressure wave allows a very accurate adjustment of the energy to be transmitted to the explosive active mass, so that very reliably only a deflagrative and non-detonatory successful implementation of the active mass can be initiated.

Fig. 1 zeigt einen erfindungsgemäßen Wirkkörper mit einer Sprengstoffwirkmasse 10, die in einer Wirkkörperhülle 12 enthalten ist. Weiterhin ist zur Zündung der Sprengstoffwirkmasse 10 eine aus einem ersten Detonator 14 und einer ersten Verstärkungsladung 16 gebildete erste Zündkette 18 vorhanden. Auf der Außenseite der Wirkkörperhülle 12 ist eine Schneidladung 22 angeordnet, die eine Wirkladung 24 enthält. Die Wirkladung 24 wird über eine den zweiten Detonator 20 und eine hier nicht dargestellte zweite Verstärkungsladung umfassende zweite Zündkette gezündet, wenn die Sprengstoffwirkmasse 10 nicht oder nicht nur detonativ, sondern deflagrativ oder auch deflagrativ zerstört werden soll. Die Schneidladung 22 durchtrennt dann die Wirkkörperhülle 12 und bewirkt dabei das Einkoppeln einer Druckwelle in die Sprengstoffwirkmasse 10. Durch die Druckwelle wird eine deflagrative Umsetzung der Sprengstoffwirkmasse 10 ausgelöst. Gleichzeitig bewirkt das Durchtrennen der Wirkkörperhülle 12 eine Druckentlastung und vermeidet dadurch sehr zuverlässig einen Übergang der deflagrativen Umsetzung der Sprengstoffwirkmasse 10 in eine detonative Umsetzung. Fig. 1 shows an active body according to the invention with an explosive active mass 10, which is contained in a working body shell 12. Furthermore, a first ignition chain 18 formed from a first detonator 14 and a first boost charge 16 is provided for igniting the explosive active mass 10. On the outside of the active body shell 12, a cutting charge 22 is arranged, which contains an active charge 24. The active charge 24 is ignited via a second detonator 20 and a second boost charge, not shown here comprising second ignition chain when the explosives active mass 10 is not destroyed or not only detonation, but deflagration or deflagration. The cutting charge 22 then cuts through the active body shell 12 and thereby causes the coupling of a pressure wave in the explosive active mass 10. By the pressure wave, a deflagrative implementation of the explosive active mass 10 is triggered. At the same time the severing of the active body shell 12 causes a pressure relief and thereby avoids very reliably a transition of the deflagrativen implementation of the explosive active material 10 in a detonative implementation.
