Thus, a further flexibility of the metering of the charge is achieved.

Description

Die Erfindung betrifft ein Verfahren zur Leistungssteuerung eines Gefechtskopfes, dessen zylindrische Sprengladung eine definierte Porosität aufweist, wobei mittels Deformation wenigstens ein Teil der Sprengladung komprimiert wird.The invention relates to a method for power control of a warhead, the cylindrical explosive charge having a defined porosity, wherein by deformation at least a portion of the explosive charge is compressed.

Die DE 198 21 150 C1 , welche einen Ausgangspunkt für den unabhängigen Patentanspruch bildet, beschreibt eine detonativ deformierbare Sprengladung. Zur Unterstützung der Deformation wird poröser Sprengstoff mit einer Porosität von 5 - 25 % verwendet. Die typische Volumenreduktion beträgt dabei etwa 5 - 10 %. Es wird die Anwendung der einseitigen Deformation der Sprengladung beschrieben, die das Ziel hat, die Leistung der Sprengladung und der damit erzeugten Splitter in eine gewünschte Richtung zu konzentrieren um damit in dieser Richtung die Wirkung zu steigern. Die noch nicht deformierte Sprengladung ist hierbei in Abhängigkeit von der Porosität immer noch detonationsfähig.The DE 198 21 150 C1 , which forms a starting point for the independent claim, describes a detonatively deformable explosive charge. In order to assist deformation, porous explosive having a porosity of 5 - 25% is used. The typical volume reduction is about 5 - 10%. It describes the application of the one-sided deformation of the explosive charge, which aims to concentrate the power of the explosive charge and the splinters produced in it in a desired direction in order to increase the effect in this direction. The not yet deformed explosive charge is still detonationsfähig depending on the porosity.

Die DE 10 2005 031588 B3 beschreibt einen Gefechtskopf, der eine poröse Sprengladung aufweist, die teilweise mittels Deflagration zerlegt werden kann und dessen anderer Teil die Volumensteigerung des deflagrierenden Teils durch Verformung (Komprimierung) aufnehmen kann. Die poröse Sprengladung ist jedoch auch vor der Verformung bereits detonationsfähig. Somit wird über die Reduzierung der Leistung des Gefechtskopfes auch eine Reduzierung kollateraler Schäden erreicht.The DE 10 2005 031588 B3 describes a warhead having a porous explosive charge, which can be partially decomposed by means of deflagration and the other part of which can accommodate the increase in volume of the deflagration part by deformation (compression). However, the porous explosive charge is already detonated before deformation. Thus, reducing the performance of the warhead also reduces collateral damage.

Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine vorteilhafte Alternative zu den vorgenannten Beispielen zu entwickeln, welche sich vor der Initiierung quasi wie eine inerte Ladung verhält, bzw. bei ungewollter Zündung maximal eine niedrige deflagrative Leistung abgibt um eine hohe Sicherheit bei Lagerung und Transport zu erzielen.In contrast, the present invention has the object to develop an advantageous alternative to the aforementioned examples, which behaves quasi like an inert charge prior to initiation, or emits a low deflagration power at maximum unintentional ignition to a high level of safety during storage and transport to achieve.

Diese Aufgabe wird erfindungsgemäß durch das beschriebene Verfahren gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the method described. Further developments of the invention are specified in the subclaims.

Die in den Ansprüchen beschriebenen Verfahren können unter dem Thema axiale Verdichtungsstoßwelle zusammengefasst werden. Somit wird in vorteilhafter Weise die poröse Sprengladung, die eine niedrige Dichte unterhalb der Detonationsgrenze aufweist, mittels gesteuerter axialer Kompression wenigstens teilweise auf eine höhere Dichte verdichtet, die über der Detonationsgrenze liegt. Dieser Teil der Sprengladung lässt sich dann mittels einer weiteren Zündeinrichtung detonativ umsetzen. Im Ausgangszustand ist diese Sprengladung aufgrund ihrer Dichte nur deflagrativ initiierbar. Je weiter jedoch die axiale Kompression fortschreitet um so mehr Teile der Sprengladung werden über die Detonationsgrenze hinaus verdichtet. Durch geschickte Wahl des Zündzeitpunkts der Sprengladung ergibt sich daraus eine Steuerung der detonativen Wirkung der Sprengladung im Bereich von 0 bis 100 %. Im Fall eines splitterbildenden Gefechtskopfes kann somit die Splittererzeugung in weiten Grenzen eingestellt werden.The methods described in the claims can be summarized under the topic axial compression shock wave. Thus, advantageously, the porous explosive charge, which has a low density below the detonation limit, is at least partially compressed by means of controlled axial compression to a higher density which is above the detonation limit. This part of the explosive charge can then be implemented detonatively by means of another ignition device. In the initial state, this explosive charge due to their density can only be initiated deflagrativ. However, the further the axial compression progresses, the more parts of the explosive charge are compressed beyond the detonation limit. By skillful choice of the ignition timing of the explosive charge, this results in a control of the detonative effect of the explosive charge in the range of 0 to 100%. In the case of a fragment-forming warhead thus splinter production can be adjusted within wide limits.

Der besondere Vorteil einer erfindungsgemäßen Sprengladung ist die hohe Sicherheit bei Lagerung und Transport. Die poröse Sprengladung ist vor der Kompression sehr sicher, weil die Sprengladung eine Dichte aufweist, die deutlich unterhalb der so genannten kritischen Dichte liegt, die die Grenze für die Detonationsfähigkeit darstellt. Somit können die Bedingungen für die Safety Tests ohne Probleme erfüllt werde und die Klassifikation einer solchen Sprengladung ist wesentlich unkritischer.The particular advantage of an explosive charge according to the invention is the high safety during storage and transport. The porous explosive charge is very safe from compression because the explosive charge has a density well below the so-called critical density, which is the limit for detonation capability. Thus, the conditions for the safety tests can be fulfilled without any problems and the classification of such an explosive charge is much less critical.

In vorteilhafter Weise erfolgt die Kompression mit Hilfe einer an der Stirnseite der zylindrischen Ladung anliegenden inerten Platte, die mittels einer weiteren geeigneten Sprengladung in Richtung Sprengladung hin beschleunigt wird und letztere damit komprimiert. Die inerte Platte kann als Einlage einer EFP-Ladung konzipiert sein, welche nach erfolgter Initiierung mittels Vorwärtsfaltung eine ebene Platte erzeugt, die ihrerseits die poröse Sprengladung komprimiert.Advantageously, the compression takes place with the aid of an inert plate resting against the end face of the cylindrical charge, which is accelerated towards the explosive charge by means of another suitable explosive charge and the latter is thus compressed. The inert plate may be designed as an insert of an EFP charge which, upon initiation by forward folding, produces a flat plate which in turn compresses the porous explosive charge.

Alternativ zu einer inerten Platte kann stirnseitig zur Sprengladung eine Vielzahl von Detonatoren angeordnet sein, die bei gemeinsamer Zündung eine annähernd ebene Druckwelle ausbilden, die zur Kompression der porösen Sprengladung genutzt wird.As an alternative to an inert plate, a plurality of detonators can be arranged on the front side of the explosive charge, which together form an approximately flat pressure wave which is used to compress the porous explosive charge.

In vorteilhafter Weise kann die Kompression der Sprengladung nicht nur in Richtung der Hauptachse, sondern gleichzeitig auch radial erfolgen, wenn hierfür eine eigene im Bereich der Hauptachse angeordnete Sprengladung genutzt wird. An deren Stelle kann auch eine einzelne leistungsstark ausgebildete Detonationsschnur treten.Advantageously, the compression of the explosive charge not only in the direction of the main axis, but at the same time also radially, if this is a separate arranged in the region of the main axis explosive charge is used. In their place can also occur a single powerful trained detonation cord.

Weiterhin ist es vorteilhaft eine Vielzahl von Detonationsschnüren in einem Abstand rund um die Hauptachse der Sprengladung für deren Kompression einzusetzen.Furthermore, it is advantageous to use a plurality of detonation cords at a distance around the main axis of the explosive charge for their compression.

In den Figuren der Zeichnung sind verschiedene Vorrichtungen zur Durchführung des erfindungsgemäßen Verfahrens zur Leistungssteuerung eines Gefechtskopfes dargestellt und in der nachfolgenden Beschreibung erläutert. Aus der Darstellung in den Figuren ergibt sich jedoch keine Beschränkung auf genau diese Ausführungsformen.In the figures of the drawing, various devices for carrying out the method according to the invention for power control of a warhead are shown and explained in the following description. From the illustration in However, the figures are not limited to exactly these embodiments.

Die Figur 1 zeigt einen Gefechtskopf GK mit einer porösen Sprengladung PHE und einer splitterbildenden Metallhülle MH. Der Gefechtskopf ist im Ausführungsbeispiel zylindrisch ausgeführt, ohne dass dies eine Einschränkung für andere Bauformen darstellen würde. Auf der linken Seite wird die Sprengladung PHE der Figur 1 von einem Stempel beziehungsweise einer fliegenden Platte FP begrenzt. Die erste Zündkette ZK 1 wirkt auf eine ganzflächig auf der fliegenden Platte aufliegende Verstärkerladung VL, welche nach erfolgter Initiierung die fliegende Platte FP in Richtung der Hauptachse HA auf die Sprengladung PHE drückt. Dadurch findet eine Kompression der Sprengladung PHE statt. Für die Sprengladung selbst ist eine weitere Zündkette ZK 2 vorgesehen.The FIG. 1 shows a warhead GK with a porous explosive charge PHE and a fragment-forming metal shell MH. The warhead is cylindrical in the embodiment, without this being a limitation for other designs. On the left side, the charge PHE is the FIG. 1 bounded by a stamp or a flying plate FP. The first ignition chain ZK 1 acts on an entire area on the flying plate resting booster charge VL, which presses the flying plate FP in the direction of the main axis HA on the explosive charge PHE after initiation. As a result, a compression of the explosive charge PHE takes place. For the explosive charge itself, a further ignition chain ZK 2 is provided.

Nach Auslösung des Zündsystems ZK 1 beginnt, wie in Figur 2 gezeigt, der Kompressionsvorgang. In der Sprengladung PHE läuft eine Stosswelle STW der sich in der Figur 2 nach rechts bewegenden fliegenden Platte FP voraus. Der Bereich hinter der laufenden Stosswelle ist bereits zu einer weitgehend porenfreien Sprengladung HE verdichtet. Letztere lässt sich im Gegensatz zur porenhaltigen Sprengladung PHE detonativ initiieren, da ihre Dichte in Richtung auf die theoretisch maximale Dichte TMD hin komprimiert wurde. Je länger der Vorgang andauert umso weiter erhöht sich die Dichte dieser Sprengladung in Richtung TMD. Die Detonationsgeschwindigkeit nimmt linear mit der steigenden Dichte zu. Die Leistung der Sprengladung wächst ihrerseits im Quadrat der Detonationsgeschwindigkeit. Dies ermöglicht eine flexiblere Anwendung dieser Sprengladung.After triggering the ignition system ZK 1 starts, as in FIG. 2 shown the compression process. In the explosive charge PHE runs a shock wave STW in the FIG. 2 ahead to the right moving flying plate FP. The area behind the current shock wave is already compressed to a largely non-porous explosive charge HE. The latter can be initiated detonatively in contrast to the pore-containing explosive charge PHE, since its density was compressed in the direction of the theoretical maximum density TMD. The longer the process continues the further increases the density of this explosive charge in the direction of TMD. The detonation velocity increases linearly with increasing density. The performance of the explosive charge in turn grows in the square of the detonation speed. This allows a more flexible use of this explosive charge.

Die Zündung kann auf unterschiedliche Art realisiert werden. In der Figur 1 ist auf der rechten Seite der Sprengladung die weitere Zündkette ZK 2 eingezeichnet. Diese ist so ausgelegt, dass sie in der unkomprimierten Sprengladung PHE maximal eine Deflagration, minimal allenfalls eine Stoßwelle erzeugen kann. Trifft jedoch diese Stoßwelle bzw. Deflagrationsfront auf den bereits verdichteten Teil HE der Sprengladung tritt der aus der Sprengstoffphysik bekannte Schock-Detonations-Übergang (Abkürzung SDT) bzw. der Deflagrations-Detonations-Übergang (Abkürzung DDT) auf.The ignition can be realized in different ways. In the FIG. 1 is on the right side of the explosive charge the further ignition chain ZK 2 located. This is designed so that it can generate a maximum of one deflagration in the uncompressed explosive charge PHE, or at most a shockwave. However, if this shock wave or deflagration front strikes the already compressed part HE of the explosive charge, the shock-detonation transition known from explosives physics (SDT abbreviation) or the deflagration-detonation transition (abbreviation DDT) occurs.

Eine Alternative hierzu (in der Zeichnung nicht dargestellt) besteht darin, dass im Bereich der fliegenden Platte FP oder innerhalb des zuerst verdichteten Teils HE der Sprengladung eine robuste Zündkette angeordnet wird. Die erzielte Wirkung ist in beiden Fällen gleichartig. Der bereits verdichtete Teil HE der Sprengladung erzeugt die volle Splitterleistung, der noch nicht verdichtete Teil PHE gibt jedoch nur eine sehr geringfügige Splitterleistung ab. Somit lässt sich die Splitterleistung in sehr weiten Grenzen einstellen.An alternative to this (not shown in the drawing) is that in the area of the flying plate FP or within the first compressed part HE of the explosive charge a robust ignition chain is arranged. The effect achieved is similar in both cases. The already compacted part HE of the explosive charge generates the full splitter power, but the not yet compressed part PHE gives only a very small fragmentation performance. Thus, the splitter performance can be set within very wide limits.

Für die technische Auslegung dieser Lösung ist zu beachten, dass eine symmetrische Detonationsfront auf die fliegende Platte FP einwirken muss. Die wird beispielsweise durch Anwendung eines so genannten Plane-Wave-Generators; der eine planare Stoßwelle erzeugt, erreicht. Aber auch ein Zündkettensystem, das beispielsweise aus mehreren ringförmig angeordneten Detonatoren besteht, kann diese Anforderung erfüllen. Hinsichtlich der Dimensionierung der die fliegende Platte beschleunigenden scheibenförmigen Verstärkerladung VL ist anzumerken, dass diese abhängig von den Eigenschaften der PHE-Ladung und der daraus sich ergebenden Arbeit zur Schließung der Poren einzustellen ist.For the technical design of this solution, it should be noted that a symmetrical detonation front must act on the flying plate FP. This is achieved, for example, by using a so-called plane wave generator; which generates a planar shock wave reached. But even a Zündkettensystem, which consists for example of a plurality of annularly arranged detonators, can meet this requirement. With regard to the dimensioning of the disk-accelerating charge VL that accelerates the flying disk, it should be noted that this is to be set depending on the properties of the PHE charge and the work resulting therefrom for closing the pores.

Eine weitere, hier nicht dargestellte vorteilhafte Ausgestaltung zu den Figuren 1 und 2 macht sich die Technologie der explosiven Metallumformung bei so genannten EFP-Ladungen (Explosively Formed Projectiles) zunutze. Die Einlage wird gemäß Figur 1 an der Stelle der fliegenden Platte FP positioniert. Mit entsprechender Dimensionierung der Einlage und der diese umformenden Sprengladung (anstelle der Verstärkerladung VL) wird eine Vorwärtsfaltung der Einlage in Richtung der Hauptachse HA angestrebt. Dazu ist der zentrale Teil der Einlage dicker ausgelegt als die peripheren Teile. Letztere werden dann axial stärker beschleunigt als der mittlere Teil. Gleichzeitig wird die Umformenergie für die Schließung der Poren genutzt. Die Peripherie wird dabei in vorteilhafter Weise höher verdichtet als der mittlere Bereich der Sprengladung.Another, not shown here advantageous embodiment of the Figures 1 and 2 The technology of explosive metal forming takes advantage of so-called EFP charges (Explosively Formed Projectiles). The deposit will be made according to FIG. 1 positioned at the location of the flying plate FP. With appropriate dimensioning of the insert and the explosive charge transforming this (instead of the amplifier charge VL), a forward folding of the insert in the direction of the main axis HA is aimed at. For this purpose, the central part of the insert is made thicker than the peripheral parts. The latter are then accelerated more axially than the middle part. At the same time, the forming energy is used to close the pores. The periphery is advantageously compressed higher than the middle region of the explosive charge.

Die Figur 3 zeigt eine weitere Ausgestaltung der Erfindung. In diesem Fall wird die Verdichtungs-Stoßwelle überwiegend radial in die PHE-Ladung eingeleitet. Dies kann beispielsweise, wie in Figur 3 dargestellt, mittels einer axial, also in Richtung der Hauptachse angeordneten zentralen Sprengladung HEZ erfolgen, die sich über die ganze Länge der Sprengladung erstreckt und einen Durchmesser im Bereich von 5 - 25 % des Durchmessers der Sprengladung PHE aufweist. Die Sprengladung HEZ wird konventionell mittels der auf der linken Seite erkennbaren ersten Zündkette ZK 1 initiiert. Die weitere Zündkette ZK 2 auf der rechten Seite in der Figur 3 regt eine Stoß- bzw. Deflagrationswelle STW in noch nicht verdichteten Teil PHE der Sprengladung an. Die Kunststoffplatte KS dient als Dämpfung für die in der axialen Ladung HEZ anlaufenden Detonationswelle.The FIG. 3 shows a further embodiment of the invention. In this case, the compression shock wave is predominantly introduced radially into the PHE charge. This can, for example, as in FIG. 3 represented by means of an axial, ie in the direction the central axis arranged central explosive charge HEZ take place, which extends over the entire length of the explosive charge and has a diameter in the range of 5 - 25% of the diameter of the explosive charge PHE. The explosive charge HEZ is conventionally initiated by means of the first ignition chain ZK 1, which can be recognized on the left side. The further ignition chain ZK 2 on the right side in the FIG. 3 excites a shock or deflagration wave STW in not yet compressed part PHE the explosive charge. The plastic plate KS serves as damping for the incoming in the axial charge HEZ detonation wave.

Gemäß Figur 4 erzeugt die initiierte axiale Ladung HEZ neben der axial innerhalb der Ladung HEZ laufenden Detonationsfront DW eine sich vorzugsweise in radialer Richtung ausbreitende Stoßwelle STW, die den porösen Teil PHE der Sprengladung fortlaufend von links nach rechts komprimiert. Der Anteil der detonativ und splitterbildend umsetzbaren Ladungsteile HE wird durch die verzögerte Zündung der weiteren Zündkette ZK 2 bestimmt. Je länger dieser Zündzeitpunkt verzögert wird, um so größer ist der Anteil der komprimierten Ladung HE. Erreicht die Stoßwelle STW die Metallhülle MH wird hier bereits die volle Splitterleistung erreicht. Über die unterschiedlichen Geschwindigkeiten der Detonationswelle DW in der zentralen Sprengladung HEZ einerseits und der Stoßwelle STW in der diese umgebenden zu komprimierenden Sprengladung PHE andererseits lässt sich die Steigung der Front der Stoßwelle STW steuern. Indirekt beeinflusst dies das Verhältnis von umkomprimierter Ladung PHE zu komprimierter Ladung HE und damit die Dosierbarkeit der Ladung. Die Detonationsgeschwindigkeit innerhalb der zentralen Sprengladung HE lässt sich durch den Einbau von Verzögerungselementen, wie beispielsweise von Dämpfungsscheiben, beeinflussen. Beispiele für derartige Elemente wären Kunststoffe oder Metallschäume.According to FIG. 4 In addition to the detonation front DW running axially inside the charge HEZ, the initiated axial charge HEZ generates a shock wave STW which preferably propagates in the radial direction and continuously compresses the porous part PHE of the explosive charge from left to right. The proportion of detonatively and fragmentally convertible charge parts HE is determined by the delayed ignition of the further ignition chain ZK 2. The longer this ignition time is delayed, the greater the proportion of the compressed charge HE. If the shock wave STW reaches the metal shell MH, the full splitter performance is already achieved here. On the different speeds of the detonation wave DW in the central explosive charge HEZ on the one hand and the shock wave STW in the surrounding these to be compressed explosive charge PHE the other hand, the slope of the front of the shock wave STW can be controlled. Indirectly, this affects the ratio of the recompressed charge PHE to the compressed charge HE and hence the controllability of the charge. The detonation velocity within the central explosive charge HE can be influenced by the incorporation of delay elements, such as damping disks. Examples of such elements would be plastics or metal foams.

Das Verfahren nach den Figuren 3 und 4 ist besonders gut für lange Ladungen geeignet, da bei einem Verdichtungsprozess nach den Figuren 1 und 2 die zu komprimierende PHE-Säule zu lang wäre und eine vollständige Kompression nicht mehr gewährleistet wäre.The procedure according to FIGS. 3 and 4 is particularly suitable for long loads, as in a compression process after the Figures 1 and 2 the PHE column to be compressed would be too long and complete compression would no longer be guaranteed.

Eine Variante hierzu liegt vor, wenn anstelle der Kunststoffplatte KS aus den Figuren 3 und 4 ein Dämpfungsmaterial zusammen mit einem außerhalb der Kunststoffplatte angeordneten, mechanischen und/oder elektronischen Zeitglied eingebaut wird. Wenn die Detonationswelle DW das Dämpfungsmaterial erreicht wird in diesem eine gedämpfte Stoßwelle erzeugt. Beim Erreichen des Zeitgliedes ist sie noch stark genug, um ein mechanisches oder elektronisches Zeitglied zu triggern. Sie ist aber auch schwach genug, um die weitere Zündkette ZK 2 unversehrt zu lassen. Nach Ablauf der Verzögerungszeit wird die weitere Zündkette ZK 2 initiiert. Mittels Variation der Verzögerungszeiten erreicht man die einstellbare Dosierbarkeit der Ladung.A variant of this is when, instead of the plastic plate KS from the FIGS. 3 and 4 a damping material together with one outside the plastic plate arranged, mechanical and / or electronic timer is installed. When the detonation wave DW reaches the damping material, it generates a damped shock wave. Upon reaching the timer, it is still strong enough to trigger a mechanical or electronic timer. But it is also weak enough to leave the further ignition chain ZK 2 intact. After the delay time, the further ignition chain ZK 2 is initiated. By means of variation of the delay times, one achieves the adjustable meterability of the charge.

Der Durchmesser der axial angeordneten Sprengladung HEZ aus den Figuren 3 und 4 hängt natürlich von den Designparametern wie beispielsweise Dichte und Größe der noch nicht komprimierten PHE-Ladung ab. In der Regel wird dieser Durchmesser bei einem Gefechtskopf in der Größenordnung von einigen wenigen Zentimetern liegen.The diameter of the axially arranged explosive charge HEZ from the FIGS. 3 and 4 Of course, it depends on the design parameters such as density and size of the uncompressed PHE charge. In general, this diameter will be in the order of a few centimeters in a warhead.

In der Figur 5 ist in Längs- und Querschnitt eine alternative Lösung mit mehreren Detonationsschnüren DET anstelle der in Figur 3 dargestellten stangenförmigen Sprengladung HEZ dargestellt. Auch deren Auslegung hängt wiederum von der Dichte und der Größe der zu komprimierenden Ladung PHE ab. Davon abhängig ergibt sich die notwendige Anzahl und die Verteilung der Detonationsschnüre DET in der Ladung PHE.In the FIG. 5 is in longitudinal and cross-section an alternative solution with multiple detonation cords DET instead of in FIG. 3 illustrated rod-shaped explosive charge HEZ shown. Their design also depends on the density and the size of the charge PHE to be compressed. Depending on this, the necessary number and distribution of the detonation cords DET in the charge PHE results.

Derartige Detonationsschnüre sind in unterschiedlichen Konfigurationen wie beispielsweise unterschiedlichen Sprengstoffen oder unterschiedlichen Außenhüllen erhältlich. Daraus ergeben sich mithin unterschiedliche Detonationsgeschwindigkeiten, die ihrerseits eine breite Auswahl an Gestaltungsmöglichkeiten zulassen. Hieraus lässt sich dann die optimale Dosierbarkeit jeder einzelnen Ladung bestimmen.Such detonation cords are available in different configurations such as different explosives or different outer shells. This results in different detonation speeds, which in turn allow a wide range of design options. From this, the optimum meterability of each individual charge can then be determined.

In Figur 5 ist eine Anzahl von Detonationsschnüren DET radial um eine zentrale Detonationsschnur herum so angeordnet, dass sie etwa parallel zur Hautachse HA der Ladung verlaufen. Ebenso gut ist es denkbar, die Detonationsschnüre in einer spiraligen Anordnung innerhalb der Ladung PHE zu verlegen. Damit lässt sich eine lokal hohe Verdichtung der zu komprimierenden Ladung erzielen. Weitere vorteilhafte Varianten sind unter Zuhilfenahme derartiger Detonationsschnüre möglich.In FIG. 5 For example, a number of detonating cords DET are arranged radially around a central detonating cord so as to be approximately parallel to the skin axis HA of the charge. It is equally possible to lay the detonation cords in a spiral arrangement within the charge PHE. This allows a locally high compression of the charge to be compressed. Further advantageous variants are possible with the aid of such detonation cords.

Figur 6 zeigt den fortschreitenden Kompressionsvorgang nach Zündung der ersten Zündkette ZK 1. Die Detonationswellen DW laufen entlang der Detonationsschnüre DET und ziehen, ähnlich wie in Figur 4 dargestellt und beschrieben, jeweils eine Stoßwelle STW nach sich. Wie aus der Figur 6 ersichtlich, findet bereits nach einer kurzen Laufstrecke der Detonationswellen eine in radialer Richtung annähernd vollständige Kompression des porösen Ladungsteils PHE statt. Die Zündung des verdichteten Ladungsteils HE findet dann wieder auf konventionellem Weg mit Hilfe der weiteren Zündkette ZK 2 statt. FIG. 6 shows the progressive compression process after ignition of the first ignition chain ZK 1. The detonation waves DW run along the detonation cords DET and pull, similar to in FIG. 4 shown and described, each a shock wave STW after. Like from the FIG. 6 can be seen, takes place after a short course of the detonation waves in the radial direction approximately complete compression of the porous charge part PHE. The ignition of the compressed charge part HE then takes place again in the conventional way with the aid of the further ignition chain ZK 2.

Für alle hier beschriebenen Beispiele beziehungsweise die gleichartig wirkenden Ausführungsformen gilt die Bedingung, dass nicht die vollständige Verdichtung des porösen Ladungsteils PHE abgewartet werden muss, bis über die weitere Zündkette ZK 2 die Initiierung erfolgen kann. Vielmehr kann auch von dieser Zündkette beispielsweise über eine weitere Zünd- oder Detonationsschnur ein zentrales Detonationssignal an den bereits verdichteten Teil der Ladung HE herangeführt und zum gewünschten Zeitpunkt gezündet werden. Damit wird eine weitere Flexibilität der Dosierbarkeit der Ladung erreicht.For all examples described here or the embodiments having the same effect, the condition applies that the complete compaction of the porous charge part PHE does not have to be awaited until initiation can take place via the further ignition charge ZK 2. Rather, a central detonation signal can also be brought to the already compressed part of the charge HE and ignited at the desired time from this detonating chain, for example via a further ignition or detonation cord. Thus, a further flexibility of the metering of the charge is achieved.
