- the explosive charge is initiated by means of a detonating chain.
- the ignition chain consists for example of an electrically ignitable detonator, a transfer charge and a booster charge.
- the booster charge is dimensioned so that the explosive charge can be implemented detonatively.
- the warhead described includes the possibility of deformation of the splinter shell, so that an increased effect occurs in a selectable preferred direction. A change in the performance of the explosive charge is not provided.
- the FR 2561376 A which forms a Kunststoff for the claim 1, describes a warhead with an explosive charge, on the opposite two identical ignition devices are arranged with these associated booster charges. These ignition devices are designed for the detonative initiation of the explosive charge. In the case of their ignition, the detonation fronts in the explosive charge converge towards one another and cause a concentration of the detonative effect in the radial direction relative to the original running direction of the detonation fronts in the region of the impact. The ignition takes place basically at the same time. An ignition at different times is provided, but there is no provision for setting the time interval specified. It is thus achieved an increase in power in a particular direction, a controllable reduction in performance of the explosive charge is hereby not possible.
- the invention is therefore based on the object to propose a simple and reliable method of target-selectable setting the performance of the explosive charge of the warhead.
- the inventive form of the ignition device for a warhead the following advantages are achieved.
- arranging a further ignition chain to the necessary anyway for the detonation of the explosive charge detonating the deflagrative initiation of the explosive charge is possible in a simple and inexpensive manner. If both igniter chains are 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 housing 6 may be designed in a known manner adapted to the properties of the warhead. However, this design has no significant influence on the function of the present invention.
- the explosive charge 1 consists of a homogeneous explosive mass which fills the housing 6 completely over the length L and which requires the initiation of a high energy level (stimulus).
- the boundary line 7 shown in FIG. 1 between the left and the right half of the explosive 1 is explained below with reference to FIG. 2.

- the stimulus generated by the further amplifier charge 5 is significantly lower than that of the amplifier charge 3.
- Fig. 3 shows a graph of the reaction R of an explosive as a function of the level of stimulus ST introduced by the booster charge.
- a small stimulus ST up to the first dashed vertical line of the deflagration threshold does not produce any reaction with the explosive.
- An increase of the stimulus ST to values between the two dashed vertical lines of the deflagration threshold and the detonation threshold triggers a deflagration in the explosive. This means that the explosive burns at a reaction rate of about 2000 m / s without producing a detonative blast effect. If the stimulus ST is increased beyond the detonation threshold, the detonation of the explosive takes place at a reaction rate of about 8000 m / s.
- the illustrated in Fig. 1 further amplifier charge 5 is exemplified as a shaped charge.

- Another possibility of adaptation can be achieved by the preconnection of metal plates or similar acting materials, which reduce the spine effect so that only the deflagration is triggered in the explosive charge.
- booster charge which is not designed as a hollow charge
- the diameter of the booster charge in the region of the so-called critical diameter, so that the booster charge 5 itself only reacts in the form of a deflagration and thus in the explosive charge 1 only a deflagration triggers.
- FIG. 2 shows, by way of example, the course of a warhead ignition, in which only 40% of the total power of the warhead is to take effect.
- the geometric arrangement of the explosive charge corresponds to the representation in FIG. 1.
- the vertical dashed line 7 represents the boundary between the explosive component 1 a to be ignited detonatively and the explosive component 1 b burning deflagratively. Since the rate of initiation during detonation is approximately four times as high is like the burning rate of the deflagration, the deflagration triggering ignition chain 4 must be started when approaching the warhead to a target first. Only after a delay time ⁇ t is the ignition chain 2, which triggers the detonation, initiated.
- the time difference At is characterized by the difference in the propagation times t v of the deflagration to the boundary line 7, and the transit time t o of the detonation front to the boundary line 7.
- the time difference ⁇ t is 250 ⁇ s.
- the ignition chain 2 must be triggered delayed with respect to the further ignition chain 5 in order to achieve a reduction of the warhead power by 60%.
- the missile which carries the warhead, flies only a few inches, so that the detonation time, which is determined by means of integrated in the missile ignition sensor, it is not significantly affected.
- the detonation must also be initiated before the deflagration if necessary. In each case, depending on the percentage of the desired effect, it is possible to determine a certain delay time ⁇ t with which the detonation is initiated after deflagration or vice versa.
- the solution according to the invention also makes it possible to retrofit existing warheads with a detonating chain 5 to initiate a deflagration. If the construction and the spatial accessibility allow it, such a device can be added to each existing warhead retroactively to the explosive charge.
- the existing ignition system is then extended by a second ignition output whose ignition signal is offset in relation to the ignition signal for the detonation release accordingly.

Description
Die Erfindung betrifft eine Sprengladung für einen Gefechtskopf, wobei die Sprengladung eine Zündeinrichtung aufweist, die eine erste Zündkette mit einer Verstärkerladung zur detonativen Initiierung enthält, der eine weitere Zündkette mit einer weiteren Verstärkerladung beabstandet zur ersten Zündkette zugeordnet ist und die Zündung der ersten und der zweiten Verstärkerladung zum gleichen Zeitpunkt oder zu verschiedenen Zeitpunkten erfolgt.The invention relates to an explosive charge for a warhead, wherein the explosive charge comprises an ignition device which contains a first detonating chain with a detonating charge boost charge, which is assigned a further detonating chain with a further boost charge spaced from the first detonating chain and the ignition of the first and the second Boost charge takes place at the same time or at different times.
Aus der Druckschrift DE 41 39 372 C1 ist ein Gefechtskopf bekannt geworden, dessen Sprengladung mit Hilfe einer Zündkette initiiert wird. Die Zündkette besteht beispielsweise aus einem elektrisch zündbaren Detonator, einer Übertragungsladung und einer Verstärkerladung. Die Verstärkerladung ist so dimensioniert, dass die Sprengladung detonativ umgesetzt werden kann. Der beschriebene Gefechtskopf umfasst die Möglichkeit einer Verformung des Splittermantels, so dass eine erhöhte Wirkung in einer wählbaren Vorzugsrichtung auftritt. Eine Veränderung der Leistung der Sprengladung ist jedoch nicht vorgesehen.From the document DE 41 39 372 C1 a warhead is known, the explosive charge is initiated by means of a detonating chain. The ignition chain consists for example of an electrically ignitable detonator, a transfer charge and a booster charge. The booster charge is dimensioned so that the explosive charge can be implemented detonatively. The warhead described includes the possibility of deformation of the splinter shell, so that an increased effect occurs in a selectable preferred direction. A change in the performance of the explosive charge is not provided.
Die FR 2561376 A, die eine Gründlage für den Anspruch 1 bildet, beschreibt einen Gefechtskopf mit einer Sprengladung, an der gegenüberliegend zwei gleichartige Zündeinrichtungen mit diesen zugeordneten Verstärkerladungen angeordnet sind. Diese Zündeinrichtungen sind für die detonative Initiierung der Sprengladung ausgelegt. Im Fall ihrer Zündung laufen die Detonationsfronten in der Sprengladung aufeinander zu und bewirken im Bereich des Aufeinandertreffens eine Konzentration der detonativen Wirkung in radialer Richtung zur ursprünglichen Laufrichtung der Detonationsfronten. Die Zündung erfolgt grundsätzlich gleichzeitig. Eine Zündung zu verschiedenen Zeitpunkten ist vorgesehen, es ist jedoch keine Maßgabe für die Einstellung des zeitlichen Abstandes angegeben. Es wird somit eine Leistungserhöhung in einer bestimmten Richtung erzielt, eine steuerbare Leistungsminderung der Sprengladung ist hiermit jedoch nicht möglich.The FR 2561376 A, which forms a Grundlage for the
Das Einsatzfeld heutiger Gefechtsköpfe verändert sich zunehmend. Es werden immer öfter Ziele in urbaner Umgebung ausgewählt, um die gegnerische Infrastruktur zu schwächen. Diese Ziele zeichnen sich durch extreme örtliche Nähe zu zivilen und anderen Einrichtungen aus, die nicht oder nur wenig beschädigt werden sollen. Da die bevorzugte Wirkrichtung eines Gefechtskopfes bauartbedingt vorgegeben ist, bleibt als Möglichkeit zur Reduzierung der Schäden in der Zielumgebung nur die Beeinflussung der Leistung des Gefechtskopfes.The field of action of today's warheads is changing increasingly. Destinations in urban environments are increasingly being chosen to weaken the enemy infrastructure. These goals are characterized by extreme local proximity to civilian and other facilities that are not or only slightly damaged. Since the preferred direction of action of a warhead is predetermined by design, remains as a way to reduce the damage in the target environment only influencing the performance of the warhead.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine einfache und funktionssichere Methode der zielabhängig wählbaren Einstellung der Leistung der Sprengladung des Gefechtskopfes vorzuschlagen.The invention is therefore based on the object to propose a simple and reliable method of target-selectable setting the performance of the explosive charge of the warhead.
Die Aufgabe wird auf vorteilhafte Weise durch die in den Ansprüchen 1 und 8 wiedergegebenen Merkmale gelöst. Günstige Ausführungsformen sind in den untergeordneten Ansprüchen beschriebenThe object is achieved in an advantageous manner by the reproduced in
Mit der erfindungsgemäßen Form der Zündeinrichtung für einen Gefechtskopf werden folgende Vorteile erzielt. Durch die Anordnung einer weiteren Zündkette zu der ohnehin für die detonative Auslösung der Sprengladung notwendigen Zündkette ist auf einfache und wenig aufwendige Weise auch die deflagrative Initiierung der Sprengladung möglich. Liegen sich beide Zündketten bezüglich der Längsachse der Sprengladung gegenüber, so ist mittels geeigneter Wahl der beiden Zündzeitpunkte sogar die beliebige Einstellung des deflagrierenden Anteils der Sprengladung zwischen 0 und 100% erzielbar.With the inventive form of the ignition device for a warhead the following advantages are achieved. By arranging a further ignition chain to the necessary anyway for the detonation of the explosive charge detonating the deflagrative initiation of the explosive charge is possible in a simple and inexpensive manner. If both igniter chains are 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.

In der Fig. 1 ist eine Sprengladung 1 eines Gefechtskopfes dargestellt, die in einem Gehäuse 6 angeordnet ist. Das Gehäuse 6 kann in bekannter Weise an die Eigenschaften des Gefechtskopfes angepasst gestaltet sein. Diese Gestaltung hat jedoch keinen wesentlichen Einfluß auf die Funktion der hier vorliegenden Erfindung. Die Sprengladung 1 besteht aus einer homogenen Sprengstoffmasse, die das Gehäuse 6 vollständig über die Länge L ausfüllt und die zur Initiierung eines hohen Energieniveaus (Stimulus) bedarf. Die in der Fig. 1 dargestellte Grenzlinie 7 zwischen der linken und der rechten Hälfte des Sprengstoffes 1 wird nachfolgend anhand der Fig. 2 erläutert.1 shows an
An der rechten Stirnseite des Gehäuses 6 ist eine Zündkette 2 bekannter Bauart angebracht. Üblicherweise werden dreistufige Zündketten verwendet, die aus einem elektrisch zündbaren Detonator, einer Übertragerladung und einer Verstärkerladung bestehen. Zur erfindungsbezogenen Vereinfachung wird hier nur auf die Verstärkerladung 3 Bezug genommen, die unmittelbar auf die Sprengladung 1 einwirkt. Mit Hilfe der Zündkette 2 erfolgte bisher nach Erfassung eines Zieles und der Erzeugung eines entsprechenden Zündsignals mittels einer bekannten Zünd- und Sicherungseinrichtung (nicht dargestellt) die detonative Auslösung der gesamten Sprengladung 1.At the right end side of the housing 6, a priming chain 2 of known type is attached. Usually, three-stage igniters are used consisting of an electrically ignitable detonator, a Übertragerladung and a booster charge. For simplification related to the invention, reference is made here only to the
Gemäß dem Ausführungsbeispiel der Erfindung wird auf der gegenüberliegenden Stirnseite des Gehäuses 6 eine weitere Zündkette 4 angeordnet. Diese weitere Zündkette 4 weist als Verstärkerladung 5 eine deflagrationsauslösende Vorrichtung auf. Eine mögliche Ausführung ist beispielsweise -eine Hohlladung. Grundsätzlich ist die weitere Verstärkerladung 5 so dimensioniert, dass sie nur ein für die Deflagration der Sprengladung 1 ausreichendes Energieniveau erzeugen kann. Der von der weiteren Verstärkerladung 5 erzeugte Stimulus liegt deutlich unter demjenigen der Verstärkerladung 3.According to the embodiment of the invention, a further ignition chain 4 is arranged on the opposite end face of the housing 6. This further ignition chain 4 has as amplifier charge 5 a deflagration-triggering device. One possible embodiment is, for example, a shaped charge. In principle, the further booster charge 5 is dimensioned such that it can only produce an energy level sufficient for the deflagration of the
Zur Verdeutlichung wird auf die Fig. 3 verwiesen, die ein Diagramm der Reaktion R eines Sprengstoffes in Abhängigkeit von der Höhe des Stimulus ST, der durch die Verstärkerladung eingebracht wird, aufzeigt. Ein geringer Stimulus ST bis zur ersten gestrichelten vertikalen Linie der Deflagrationsschwelle erzeugt beim Sprengstoff keine Reaktion. Eine Erhöhung des Stimulus ST auf Werte zwischen den beiden gestrichelten vertikalen Linien der Deflagrationsschwelle und der Detonationsschwelle löst im Sprengstoff eine Deflagration aus. Das bedeutet, dass der Sprengstoff mit einer Reaktionsgeschwindigkeit von etwa 2000 m/s abbrennt ohne eine detonative Blast-Wirkung zu erzeugen. Wird der Stimulus ST über die Detonationsschwelle hinaus erhöht, so erfolgt die Detonation des Sprengstoffes mit einer Reaktionsgeschwindigkeit von etwa 8000 m/s.For clarity, reference is made to Fig. 3, which shows a graph of the reaction R of an explosive as a function of the level of stimulus ST introduced by the booster charge. A small stimulus ST up to the first dashed vertical line of the deflagration threshold does not produce any reaction with the explosive. An increase of the stimulus ST to values between the two dashed vertical lines of the deflagration threshold and the detonation threshold triggers a deflagration in the explosive. This means that the explosive burns at a reaction rate of about 2000 m / s without producing a detonative blast effect. If the stimulus ST is increased beyond the detonation threshold, the detonation of the explosive takes place at a reaction rate of about 8000 m / s.
Die in Fig. 1 dargestellte weitere Verstärkerladung 5 ist beispielhaft als Hohlladung ausgeführt. Vorteilhafterweise wird hierbei eine sogenannte EOD-(Explosive Ordnance Disposal)-Hohlladung verwendet, die aufgrund ihrer Eigenschaften geeignet ist, eine nichtdetonative Reaktion in der Sprengladung auszulösen. Dies wird dadurch erreicht, dass die Stärke des von der Hohlladung erzeugten Stachels durch die Wahl des Kalibers der Hohlladung so eingestellt wird. dass der damit erzeugte Stimulus ST entsprechend dem Diagramm in Figur 3 im Bereich zwischen der Deflagrations- und der Detonationsschwelle liegt. Eine weitere Möglichkeit der Anpassung kann durch die Vorschaltung von Metallplatten oder ähnlich wirkenden Materialien erreicht werden, welche die Stachelwirkung so reduzieren, dass in der Sprengladung nur die Deflagration ausgelöst wird. Im Fall einer Verstärkerladung, die nicht als Hohlladung ausgeführt ist, besteht noch die Möglichkeit, den Durchmesser der Verstärkerladung im Bereich des sogenannten kritischen Durchmessers zu wählen, so dass die Verstärkerladung 5 selbst nur in Form einer Deflagration reagiert und damit bei der Sprengladung 1 auch nur eine Deflagration auslöst.The illustrated in Fig. 1 further amplifier charge 5 is exemplified as a shaped charge. Advantageously, in this case a so-called EOD (Explosive Ordnance Disposal) hollow charge is used, which is suitable because of their properties, a non-detonative reaction in the To trigger explosive charge. This is achieved by adjusting the thickness of the sting produced by the shaped charge by selecting the caliber of the shaped charge. that the stimulus ST generated in accordance with the diagram in FIG. 3 lies in the region between the deflagration threshold and the detonation threshold. Another possibility of adaptation can be achieved by the preconnection of metal plates or similar acting materials, which reduce the spine effect so that only the deflagration is triggered in the explosive charge. In the case of a booster charge, which is not designed as a hollow charge, there is still the possibility to choose the diameter of the booster charge in the region of the so-called critical diameter, so that the booster charge 5 itself only reacts in the form of a deflagration and thus in the
In Fig. 2 ist beispielhaft der Ablauf einer Gefechtskopfzündung dargestellt, bei der nur 40 % der Gesamtleistung des Gefechtskopfes zur Wirkung kommen sollen. Die geometrische Anordnung der Sprengladung entspricht dabei der Darstellung in Fig. 1. Die vertikale gestrichelte Linie 7 stellt dabei die Grenze zwischen den detonativ zu zündenden Sprengstoffanteil 1a und dem deflagrativ abbrennenden Sprengstoffanteil 1b dar. Da die Geschwindigkeit der Initiierung bei der Detonation etwa viermal so hoch ist wie die Abbrandgeschwindigkeit der Deflagration, muss bei der Annäherung des Gefechtskopfes an ein Ziel zuerst die die Deflagration auslösende Zündkette 4 gestartet werden. Erst nach einer Verzögerungszeit Δt wird die Zündkette 2, die die Detonation auslöst, initiiert. Die Zeitdifferenz Δt ist charakterisiert durch die Differenz der Laufzeiten tv der Deflagrationsfront bis zur Grenzlinie 7 und der Laufzeit to der Detonationsfront bis zur Grenzlinie 7. Bei einem Beispiel eines Gefechtskopfes mit einer Länge L = 1000 mm betragen die Laufzeiten bis zur Grenzlinie 7 bei der Deflagrationsfront tv = 300µs und bei der Detonationsfront to = 50µs. Somit ergibt sich die Zeitdifferenz Δt zu 250µs. Um diese Zeitdifferenz Δt muss die Zündkette 2 verzögert gegenüber der weiteren Zündkette 5 ausgelöst werden, um eine Reduzierung der Gefechtskopfleistung um 60% zu erreichen. In dieser Zeit fliegt der Flugkörper, der den Gefechtskopf trägt, nur wenige Zentimeter weit, so dass der Detonationszeitpunkt, der mit Hilfe der im Flugkörper integrierten Zündsensorik ermittelt wird, davon nicht wesentlich beeinflußt wird.FIG. 2 shows, by way of example, the course of a warhead ignition, in which only 40% of the total power of the warhead is to take effect. The geometric arrangement of the explosive charge corresponds to the representation in FIG. 1. The
Soll der Wert der von der Sprengladung abgegebenen Leistung kontinuierlich zwischen 0% und 100% eingestellt werden, muss gegebenenfalls die Detonation auch vor der Deflagration eingeleitet werden. Es läßt sich in jedem Fall abhängig von dem Prozentsatz der gewünschten Wirkung eine bestimmte Verzögerungszeit Δt bestimmen, mit der die Detonation nach der Deflagration initiiert wird oder umgekehrt.If the value of the power delivered by the explosive charge is to be set continuously between 0% and 100%, the detonation must also be initiated before the deflagration if necessary. In each case, depending on the percentage of the desired effect, it is possible to determine a certain delay time Δt with which the detonation is initiated after deflagration or vice versa.
Die erfindungsgemäße Lösung erlaubt auch die Nachrüstung bestehender Gefechtsköpfe- mit einer Zündkette 5 zur Initiierung einer Deflagration. Wenn der Aufbau und die räumliche Zugänglichkeit es erlauben, kann eine derartige Vorrichtung bei jedem existierenden Gefechtskopf nachträglich an die Sprengladung angebaut werden. Das bestehende Zündsystem wird dann um einen zweiten Zündausgang erweitert, dessen Zündsignal gegenüber dem Zündsignal für die Detonationsauslösung entsprechend zeitversetzt ist.The solution according to the invention also makes it possible to retrofit existing warheads with a detonating chain 5 to initiate a deflagration. If the construction and the spatial accessibility allow it, such a device can be added to each existing warhead retroactively to the explosive charge. The existing ignition system is then extended by a second ignition output whose ignition signal is offset in relation to the ignition signal for the detonation release accordingly.
