Definitions
- the invention relates to a fragmentary projectile as defined by the preamble of claim 1.
- Such fragments are known for example from US-A-3,566,794.
- a plurality of casings abutting one another are arranged around the centrally arranged explosive, each of which has V-shaped predetermined breaking points in order to produce the largest possible number of fragments.
- the predetermined breaking points of the casing closest to the explosive are provided with the predetermined breaking points on the explosive side.
- a multi-shell fragmentary projectile in which the shell closest to the explosive has V-shaped grooves on the explosive side which do not change the wall thickness of the shell.
- the grooves are designed such that the corresponding groove walls act like local shaped charge inserts. This means that the V-shaped groove walls on the explosives side directly from explosives must be surrounded and must therefore be arranged in any case on the side of the shell facing the explosives.
- the local shaped charges act on the outer shell, which then first tears along those areas which lie opposite the V-shaped grooves.
- US-A-4,106,411 discloses a fragmentary projectile which has several casings with structural zones. Areas are filled with explosives between the inner casings and areas with a fire mass between the outer casings. In these explosive projectiles too, the fire mass reaches the target practically simultaneously with the shell fragments, so that ignition of the combustible liquid of a target cannot be ensured.
- a splinter floor is shown in Fig. 2, which also consists of several shell casings. In this case, however, the splinter shell and the zirconium shell causing the fire effect are separate units.
- a disadvantage of this invention is the fact that a large number of undefined fragments arise. There is no reproducible splinter distribution.
- the object of the present invention is, based on US 3,566,794, to further develop a splinter projectile in such a way that the actual splinter casing is particularly easy to manufacture, and that in addition a desired fire effect, e.g. B. when fighting aircraft tanks.
- the invention is therefore based on the idea of generating an optimization of the splintering and fire effects in that the structural zones of the inner shell consist of areas of smaller wall thickness than the parts of the shell surrounding the structural zones.
- the wall thicknesses, casing materials and the number of casings determine the shape and mass distribution of the fragments and - depending on the intended use - can be optimally adapted to the target requirements.

- the shell is composed of the outer shell 2 and 3 and the inner shell 4.
- Structural zones 7 are located in the inner shell 4 on the side facing away from the explosive 5. These structural zones 7 are selected such that the remaining wall thickness of the shell 4 at these points is less than the wall thickness of the parts of the shell 4 surrounding the structural zones.
- FIG. 4 and 4a and 5 and 5a two further exemplary embodiments of the inner shell 4 ', 4' 'with structural zones 7', 7 '' are shown.
- 4 shows a top view
- FIG. 4a shows a cross section of the inner shell 4 'with a structure zone distribution which is selected such that the parts of the shell 4' surrounding the structure zones have an approximately rectangular shape.

Description
Die Erfindung betrifft ein Splittergeschoß, wie es durch den Gattungsbegriff des Anspruchs 1 definiert ist.The invention relates to a fragmentary projectile as defined by the preamble of claim 1.
Derartige Splittergeschosse sind beispielsweise aus der US-A-3,566,794 bekannt. Bei diesen Geschossen sind um den zentral angeordneten Sprengstoff mehrere aneinander anliegende Hüllen angeordnet, die jeweils V-förmige Sollbruchstellen aufweisen, um eine möglichst große Anzahl von Splittern zu erzeugen. Dabei sind die Sollbruchstellen der dem Sprengstoff nächsten Hülle sprengstoffseitig mit den Sollbruchstellen versehen.Such fragments are known for example from US-A-3,566,794. In the case of these projectiles, a plurality of casings abutting one another are arranged around the centrally arranged explosive, each of which has V-shaped predetermined breaking points in order to produce the largest possible number of fragments. The predetermined breaking points of the casing closest to the explosive are provided with the predetermined breaking points on the explosive side.
Abgesehen davon, daß diese bekannten Splittergeschosse mehrere relativ aufwendige Hüllenstrukturen erfordern, ergeben sich bei Verwendung dieser Geschosse besonders dann Probleme, wenn die Hüllen mit Brandmassen versehen werden, um eine entzündbare Flüssigkeit (z.B. eines Flugzeugtanks) zu entzünden. Denn häufig erlöscht die Brandmasse beim Eintauchen der entsprechenden Splitter in die Flüssigkeit.In addition to the fact that these known fragmentary projectiles require several relatively complex casing structures, problems arise when using these projectiles, in particular if the casings are provided with fire masses in order to ignite an inflammable liquid (e.g. an aircraft tank). Because the fire mass often extinguishes when the corresponding splinters are immersed in the liquid.
Aus der US-A-3,000,309 ist ein aus mehreren Hüllen bestehendes Splittergeschoß bekannt, bei dem die dem Sprengstoff nächste Hülle sprengstoffseitig V-förmige Nuten aufweist, welche die Wandstärke der Hülle nicht verändern. Die Nuten sind dabei derart ausgebildet, daß die entsprechenden Nutenwände wie lokale Hohlladungseinlagen wirken. Dieses bedeutet, daß die V-förmigen Nutenwände sprengstoffseitig direkt von Sprengstoff umgeben sein müssen und somit in jedem Fall auf der dem Sprengstoff zugewandten Seite der Hülle anzuordnen sind. Bei der Detonation wirken die lokalen Hohlladungen auf die Außenhülle, die dann zunächst entlang derjenigen Bereiche reißt, die den V-förmigen Nuten gegenüber liegen.From US-A-3,000,309 a multi-shell fragmentary projectile is known, in which the shell closest to the explosive has V-shaped grooves on the explosive side which do not change the wall thickness of the shell. The grooves are designed such that the corresponding groove walls act like local shaped charge inserts. This means that the V-shaped groove walls on the explosives side directly from explosives must be surrounded and must therefore be arranged in any case on the side of the shell facing the explosives. During the detonation, the local shaped charges act on the outer shell, which then first tears along those areas which lie opposite the V-shaped grooves.
Nachteilig bei diesem bekannten Geschoß ist ebenfalls, daß eine aufwendige und damit teure Hüllenstruktur erforderlich ist. Außerdem läßt sich bei diesem Geschoß keine Brandmasse auf der dem Sprengstoff zugewandten Hüllenwand aufbringen, weil sonst die Funktion der V-förmigen Nuten als Hohlladung verloren gehen würde.Another disadvantage of this known projectile is that a complex and therefore expensive casing structure is required. In addition, no fire can be applied to the shell wall facing the explosive in this projectile, because otherwise the function of the V-shaped grooves as a shaped charge would be lost.
Aus der US-A-4.381,692 ist ferner bekannt, eine mit Kerben versehene Brandmasse auf der Innenseite der Geschoßhülle von Splittergeschossen anzuordnen. Mit einer derartigen Anordnung ist allerdings der Nachteil verbunden, daß die Brandmasse praktisch gleichzeitig mit den Hüllensplittern in das Ziel gelangt, was vermieden werden soll, weil die Splitter zusammen mit den Brandmassen in die entzündbare Flüssigkeit eintauchen und häufig sofort erlöschen.From US-A-4,381,692 it is also known to arrange a notched fire mass on the inside of the shell of fragmentary projectiles. With such an arrangement, however, there is the disadvantage that the fire mass reaches the target practically simultaneously with the shell fragments, which should be avoided because the splinters are immersed in the flammable liquid together with the fire masses and often go out immediately.
Die US-A-4,106,411 offenbart ein Splittergeschoß, welches mehrere Hüllen mit Strukturzonen besitzt. Dabei sind zwischen den inneren Hüllen Bereiche mit Sprengstoff und zwischen den äußeren Hüllen Bereiche mit einer Brandmasse ausgefüllt. Auch bei diesen Sprenggeschossen gelangt die Brandmasse praktisch gleichzeitig mit den Hüllensplittern in das Ziel, so daß eine Entzündung der brennbaren Flüssigkeit eines Zieles nicht sichergestellt werden kann.US-A-4,106,411 discloses a fragmentary projectile which has several casings with structural zones. Areas are filled with explosives between the inner casings and areas with a fire mass between the outer casings. In these explosive projectiles too, the fire mass reaches the target practically simultaneously with the shell fragments, so that ignition of the combustible liquid of a target cannot be ensured.
In der DE-B-23 39 386 wird in Fig. 2 ein Splittergeschoß dargestellt, welches ebenfalls aus mehreren Geschoßhüllen besteht. Allerdings sind in diesem Fall die Splitterhülle und die die Brandwirkung verursachende Zirkoniumhülle getrennte Einheiten.In DE-B-23 39 386 a splinter floor is shown in Fig. 2, which also consists of several shell casings. In this case, however, the splinter shell and the zirconium shell causing the fire effect are separate units.
Zum einen besteht bei diesen bekannten Geschossen der Nachteil, daß keine gerichtete Splitterwirkung gegeben ist, sondern daß die Splitterverteilung annähernd zylindersymmetrisch ist. Zum anderen ist die Wirksamkeit der leichten Zirkoniumsplitter, insbesondere bei größeren Zielentfernungen, sehr fraglich, da die Penetrationswirkung dieser Splitter gering ist.On the one hand, there is the disadvantage with these known projectiles that there is no directional splintering effect, but that the splinter distribution is approximately cylinder-symmetrical. On the other hand, the effectiveness of the light zirconium splinters is very questionable, especially with larger target distances, since the penetration effect of these splinters is low.
Aus der US-A-4,089,267 ist ein Splittergeschoß bekannt, bei dem zur Erhöhung der Splitteranzahl der Sprengstoff von zwei Hüllen umgeben ist. Zwischen den beiden Hüllen muß ein Spalt bestehen, der mit einem Material geringer Dichte (Luft, Schaum) ausgefüllt wird. Nach der Zündung des Sprengstoffes drückt die Innenhülle schlagartig auf die Außenhülle, so daß es zu einer relativ hohen Splitterbildung kommt.From US-A-4,089,267 a fragmentary projectile is known in which the explosive is surrounded by two shells to increase the number of fragments. There must be a gap between the two shells, which is filled with a low-density material (air, foam). After the explosive is detonated, the inner shell suddenly presses on the outer shell, so that there is a relatively high formation of fragments.
Nachteilig bei dieser Erfindung ist die Tatsache, daß eine große Anzahl undefinierter Splitter entsteht. Es ergibt sich keine reproduzierbare Splitterverteilung.A disadvantage of this invention is the fact that a large number of undefined fragments arise. There is no reproducible splinter distribution.
Die Aufgabe der vorliegenden Erfindung besteht darin, ausgehend von der US 3,566,794, ein Splittergeschoß so weiterzuentwickeln, daß die eigentliche Splitterhülle besonders einfach zu fertigen ist, und daß sich zusätzlich eine erwünschte Brandwirkung, z. B. beim Bekämpfen von Flugzeugtanks, ergibt.The object of the present invention is, based on US 3,566,794, to further develop a splinter projectile in such a way that the actual splinter casing is particularly easy to manufacture, and that in addition a desired fire effect, e.g. B. when fighting aircraft tanks.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teiles des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.
Weitere besonders vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.Further particularly advantageous configurations result from the subclaims.
Der Erfindung liegt also der Gedanke zugrunde, eine Optimierung der Splitter- und Brandwirkung dadurch zu erzeugen, daß die Strukturzonen der Innenhülle aus Bereichen geringerer Wandstärke bestehen, als die die Strukturzonen umgebenden Teile der Hülle. Die Wanddicken, Hüllenwerkstoffe und die Hüllenanzahl bestimmen die Gestalt und Massenverteilung der Splitter und können - je nach Verwendungszweck - optimal an die Zielanforderungen angepaßt werden.The invention is therefore based on the idea of generating an optimization of the splintering and fire effects in that the structural zones of the inner shell consist of areas of smaller wall thickness than the parts of the shell surrounding the structural zones. The wall thicknesses, casing materials and the number of casings determine the shape and mass distribution of the fragments and - depending on the intended use - can be optimally adapted to the target requirements.
Der Nachteil bei herkömmlichen Splittergefechtsköpfen, bei denen die pyrophore Brandmasse mit den Splittern ins Ziel gebracht wird, und bei denen die relativ kleinen Splitter sofort in die zu entzündende Flüssigkeit eintauchen und dadurch erlöschen, ist bei der vorliegenden Erfindung nicht gegeben. Vielmehr fliegen durch Verwendung der Mehrfachhülle mehrere Splitter gestaffelt vor den mit der Brandmasse versehenen Splittern in das Ziel und bereiten den Treibstoff für eine optimale Entzündung durch die beim Eintritt entstehende Kavitationsblase oder durch Auslaufen vor.The disadvantage with conventional splinter warheads, in which the pyrophoric fire mass is brought to the target with the splinters, and in which the relatively small splinters immediately immerse in the liquid to be ignited and thereby extinguish, does not exist in the present invention. Rather, by using the multiple shell, several splinters fly in a staggered manner in front of the splinters provided with the fire mass and prepare the fuel for optimal ignition through the cavitation bubble that forms when it enters or through leakage.

Hierzu ist in Fig. 6 ein Ausschnitt aus Fig. 1 dargestellt, der die innere Geschoßhülle 4, die Strukturzonen 7 sowie die angrenzende äußere Geschoßhülle 3 zeigt.The mode of operation of the invention is discussed in more detail below. For this purpose, a section from FIG. 1 is shown in FIG. 6, which shows the
Bei der Detonation des Sprengstoffes 5 (Fig. 1) wird der entstehende Stoßwellenimpuls lokal an den Kontaktstellen 8 in die Hülle 3 eingekoppelt. In den durch die Strukturzonen 7 definierten Zwischenräumen erfolgt hingegen keine Stoßwelleneinkoppelung, da die entsprechenden Wellen am Übergang des Werkstoffes der Hülle 4 zur Luft reflektiert werden.During the detonation of the explosive 5 (FIG. 1), the resulting shock wave pulse is locally coupled into the
Die an den Kontaktstellen 8 eingekoppelte Energie beschleunigt Teilbereiche der äußeren Hülle 3 bzw. induziert in dieser Hülle Spannungsgradienten. Dieses führt zur Ausbildung von Splittern, die in ihrer Geometrie dem auf die innere Hülle eingebrachten Muster entsprechen.The energy coupled in at the contact points 8 accelerates partial regions of the
