Abstract

In an artillery shell, the outer surface of the cylindrical section (2) of the shell casing forms the trailing section of the outer surface of the mantle (1). The centering system (5,9) to take and hold the solid shot body (6) is within the pointed end (3) of the shell. The pointed end (3) and/or the sealing base body (15) are of injection moulded thermoplastic material, of high heat resistance, with glass fibre reinforcement. Also claimed is a process where the pointed end (3) and cylindrical section (2) are initially injection moulded with anchored casing ridges (4). In a second step, the solid shot payload (6) is inserted into the casing through the open trailing end into the centering structure (5,9) at the shell point (3). In a final step, the open trailing end is closed and sealed by the insertion of a base body (15).

Description

Die Erfindung betrifft ein Geschoss nach dem Oberbegriff des Patentanspruchs 1 und ein Verfahren zu dessen Herstellung.The invention relates to a projectile according to the preamble of claim 1 and a method for its production.

Derartige seit langem bekannte Geschosse, beispielsweise Stahlmantelgeschosse, besitzen einen Mantel aus Stahl und einen Geschosskern bzw. Geschosskörper aus Hartblei oder, bei sogenannten Spitzengeschossen, einen Geschosskern bzw. Geschosskörper aus Stahl. Andere Geschosse, wie zum Beispiel die für die Panzerabwehr verwendeten Hartkerngeschosse, bestehen aus einem sehr harten, schweren, panzerbrechenden Geschosskern bzw. Panzerkern und einem Mantel aus weichem Stahl. Es sind auch Geschosse bekannt, deren Mantel mindestens teilweise aus einem geeigneten Kunststoff besteht.Such long-known bullets, for example steel jacket bullets, have a steel jacket and a bullet core or bullet body made of hard lead or, in the case of so-called top floors, a floor core or floor body from steel. Other bullets, such as those used for anti-tank defense Hard core bullets consist of a very hard, heavy, armor-piercing bullet core or armored core and a jacket made of soft steel. They are also bullets known, the jacket is at least partially made of a suitable plastic.

Bei einigen dieser Geschosse, bei denen der Geschosskörper in der Regel den gesamten Mantel ausfüllt, sind Variationen des Kernes bzw. des Geschosskörpers nach Form und Grösse bei ein und demselben Kaliber bzw. Mantel kaum möglich. Andere Geschosse, bei denen es möglich wäre, gleiche Mäntel mit unterschiedlichen Geschosskörpern zu bestücken und dadurch verschiedenartige Geschosse zu erhalten, sind in der Herstellung verhältnismässig aufwendig.For some of these storeys, where the projectile body generally covers the entire Fills the jacket, are variations of the core or the body of the projectile in shape and Size hardly possible with one and the same caliber or jacket. Other floors, at who would be able to equip the same coats with different storeys and thus obtaining different types of projectiles are proportionate in their manufacture complex.

Die FR-1 242 187 beispielsweise beschreibt ein Geschoss mit einem Geschosskörper, einem Mantel aus einer Geschossspitze und einer aussen an der Geschossspitze befestigten Geschosshülle sowie einem den Mantel hinten abschliessenden Dichtungskörper, der den Geschosskörper in dessen hinterem Bereich umfasst. Der Durchmesser des Geschosskörpers ist etwa zeppelinförmig, das heisst, er nimmt von vorn nach hinten zuerst zu und verringert sich anschliessend wieder. Es ist daher nicht möglich, zuerst den Mantel herzustellen und ihn anschliessend mit dem Geschosskern zu bestücken, was erwünscht wäre, um gleiche Mäntel in grossen Serien herzustellen und aus ihnen anschliessend durch Bestückung mit unterschiedlichen Geschosskörpern verschiedene Geschosse herzustellen. Insbesondere ist es nicht möglich, die Geschossspitze durch Spritzen herzustellen. FR-1 242 187, for example, describes a projectile with a projectile body, a casing made of a projectile tip and a projectile casing fastened to the outside of the projectile tip, and a sealing body which closes the casing at the rear and encompasses the projectile body in its rear region. The diameter of the projectile body is approximately zeppelin-shaped, which means that it increases from front to back and then decreases again. It is therefore not possible to first manufacture the jacket and then to equip it with the projectile core, which would be desirable in order to produce the same casings in large series and then to produce different projectiles from them by equipping them with different projectile bodies. In particular, it is not possible to produce the tip of the projectile by injection.

Aus der FR-812 377 ist ein Geschoss bekannt, bei welchem es zwar möglich wäre, je nach Verwendungszweck gleiche Mäntel mit unterschiedlichen Geschosskernen zu bestücken. Dieses Geschoss besitzt einen vorne durch einen Ring zentrierten Geschosskörper und einen diesen umgebenden Mantel, der hinten durch einen metallischen Dichtungskörper verschlossen ist, welcher den Geschosskörper in seinem hinteren Bereich umfasst; der Dichtungskörper soll vor allem auch eine zusätzliche Masse bilden, also verhältnismässig schwer sein und muss daher aus Metall hergestellt werden. Der Mantel umfasst die Geschossspitze und die integral mit der Geschossspitze ausgebildete Geschosshülle und ist ebenfalls aus Metall hergestellt. Der Nachteil dieses Geschosses besteht im wesentlichen darin, dass seine Herstellung verhältnismässig aufwendig ist, insbesondere da Mantel und Dichtungskörper beide aus Metall bestehen, so dass es nicht möglich ist, einen der beiden Teile oder beide Teile durch Anspritzen herzustellen.A bullet is known from FR-812 377 , in which it would be possible, depending on the intended use, to equip the same jackets with different bullet cores. This projectile has a projectile body centered at the front by a ring and a casing surrounding the latter, which is closed at the rear by a metallic sealing body which surrounds the projectile body in its rear region; above all, the sealing body should also form an additional mass, that is to say be relatively heavy, and must therefore be made of metal. The jacket encompasses the projectile tip and the projectile envelope formed integrally with the projectile tip and is also made of metal. The main disadvantage of this projectile is that it is relatively complex to produce, in particular since the casing and sealing body are both made of metal, so that it is not possible to produce one or both of the parts by injection molding.

Ein weiteres Geschoss mit einem Mantel und einem Geschosskörper ist sodann aus der US-3,795,196 bekannt. Der Mantel besteht vorne aus der Geschossspitze, während der hintere Bereich des Mantels durch den Dichtungskörper gebildet ist, der gleichzeitig dazu dient, den Mantel hinten abzuschliessen; dieser Dichtungskörper besteht aus Metall. Dieses Geschoss besitzt keine Geschosshülle. Zur Zentrierung des Geschosskerns sind zwei Zentrierringe vorgesehen. Zwar würde es die Formgebung theoretisch erlauben, gleiche Mäntel mit unterschiedlichen Geschosskörpern zu bestücken. Die Geschosskörper müssten dann von vorne in den Mantel eingebracht werden. Ein Anspritzen der Geschossspitze und somit eine kostengünstige Fertigung wären aber wegen Konstruktion mit den Zentrierringen nicht möglich.Another projectile with a casing and a projectile body is then known from US Pat . No. 3,795,196 . The jacket consists of the front of the bullet tip, while the rear area of the jacket is formed by the sealing body, which also serves to seal the jacket at the rear; this sealing body is made of metal. This floor has no floor shell. Two centering rings are provided to center the projectile core. Theoretically, the shape would allow the same shells to be fitted with different storeys. The projectile bodies would then have to be inserted into the jacket from the front. Injection molding of the bullet tip and thus cost-effective production would not be possible due to the construction with the centering rings.

Schliesslich ist aus der FR-2 238 137 ein Geschoss bekannt, dessen Geschosskern in seiner vorderen Hälfte konisch und in seiner hinteren Hälfte zylindrisch ist. Dieser Geschosskern ist von einem Mantel umgeben. Die Formgebung würde es grundsätzlich erlauben, gleiche Mäntel von hinten mit unterschiedlichen Geschosskörpern zu bestücken und dadurch verschiedene Geschosse herzustellen. Der Mantel dieses Geschosses wird durch eine an einer metallischen Geschosshülle angespritzten Geschossspitze aus spritzbarem Material, genauer aus Kunststoff, gebildet. Die hintere Öffnung des Mantels ist durch einen Verschluss- bzw. Dichtungskörper verschlossen, welcher in den Mantel hineinragt und den Geschosskern zum Teil umfasst. Die Aussenfläche des Mantels wird im vorderen Geschossteil durch die Geschossspitze und im hinteren Geschossteil durch den metallischen Dichtungskörper gebildet; in dieser Beziehung ist das Geschoss gleich ausgebildet wie dasjenige der US-3,795,196, weist aber im Gegensatz zum Geschoss der erwähnten US-3,795,196 eine Geschosshülle auf. Die Geschosshülle, welche im mittigen Bereich des Geschosskörpers an diesem anliegt, liegt nicht an der Aussenfläche des Mantels sondern dient lediglich dazu, eine indirekte Schraubenverbindung zwischen der Geschossspitze und dem Dichtungskörper zu bilden. Als Zentrieranordnung für den Geschosskörper dient ein zuvorderst am in den Mantel ragenden Teil des Dichtungskörpers angeformter Kragen. Der hauptsächlich Nachteil dieses Geschosses liegt darin, dass seine Herstellung aufwendig ist, und zwar aus folgendem Grund: Der Dichtungskörper bildet den hinteren Teil der Aussenfläche des Mantels; ein Führungsring wird also am Dichtungskörper zu befestigen sein, so dass es sich aufdrängt, den Dichtungskörper aus Metall zu fertigen. Dies hat zur Folge, dass die Zentrieranordnung, welche präzise Abmessungen aufweisen muss, ebenfalls aus Metall hergestellt werden muss, was mit einem verhältnismässig grossen Aufwand verbunden ist.Finally, a projectile is known from FR-2 238 137 , the projectile core of which is conical in its front half and cylindrical in its rear half. This core is surrounded by a jacket. The shape would basically allow the same shells to be fitted with different projectile bodies from the rear and thus to produce different projectiles. The shell of this projectile is formed by a projectile tip made of sprayable material, more precisely plastic, which is molded onto a metallic projectile shell. The rear opening of the casing is closed by a closure or sealing body which projects into the casing and partially surrounds the projectile core. The outer surface of the jacket is formed in the front part of the projectile by the projectile tip and in the rear part of the projectile by the metallic sealing body; in this respect, the projectile is of the same design as that of US Pat. No. 3,795,196, but, in contrast to the projectile of US Pat . No. 3,795,196 mentioned , has a projectile casing . The projectile casing, which rests on the projectile body in the central region, does not lie on the outer surface of the casing, but merely serves to form an indirect screw connection between the projectile tip and the sealing body. A collar which is formed on the part of the sealing body which projects into the jacket serves as the centering arrangement for the projectile body. The main disadvantage of this bullet is that it is expensive to manufacture, for the following reason: the sealing body forms the rear part of the outer surface of the shell; a guide ring will therefore have to be attached to the sealing body, so that it is imperative to manufacture the sealing body from metal. The consequence of this is that the centering arrangement, which must have precise dimensions, must also be made of metal, which is associated with a relatively large outlay.

Zusammenfassend muss festgestellt werden, dass keines der bekannten Geschosse die weiter oben erwähnten Anforderungen betreffend Verwendung unterschiedlicher Geschosskörper einerseits und einfacher Herstellung anderseits erfüllt. In summary, it must be stated that none of the known storeys requirements mentioned above regarding the use of different projectile bodies on the one hand and simple manufacture on the other hand.

Der Erfindung liegt daher die Aufgabe zugrunde, ausgehend von einem Stand der Technik gemäss der FR-2 238 137, ein Geschoss der eingangs genannten Art sowie ein Verfahren zu dessen Herstellung vorzuschlagen, bei welchem der Mantel mit Geschosskörpern verschiedener Art, entsprechend dem jeweiligem Verwendungszweck, bestückt werden kann, und welches in einfacher und daher kostengünstiger Weise hergestellt werden kann.The invention is therefore based on the object, based on a prior art according to FR-2 238 137 , to propose a projectile of the type mentioned at the outset and a method for its production, in which the casing with projectile bodies of different types, in accordance with the respective intended use, can be equipped, and which can be produced in a simple and therefore inexpensive manner.

Diese Aufgabe wird durch die Merkmale der kennzeichnenden Teile der Patentansprüche 1 bzw. 10 gelöst.This object is solved by the features of the characterizing parts of claims 1 and 10 , respectively.

Beim neuen Geschoss ist der Geschosskörper so ausgebildet, dass sein Durchmesser von vorne nach hinten konstant oder zunehmend, jedenfalls aber nicht abnehmend ist, so dass der Geschosskern von hinten in den vorgefertigten Mantel eingebracht werden kann. Der Mantel besteht aus einer im allgemeinen metallischen Geschosshülle und aus einer Geschossspitze aus einem spritzbaren, ausgehärteten Material, vorzugsweise aus Kunststoff, die an die Geschosshülle angespritzt wird. Im Inneren der Geschossspitze sind eine Ausnehmung für den Geschosskern und eine Zentrieranordnung zur Führung und Fixierung des Geschosskörpers vorgesehen. Die Zentrieranordnungen ist also beim neuen Geschoss an einem gespritzten Bestandteil, eben an der Geschossspitze, vorgesehen, so dass die hohen Kosten der Fertigung der Zentrieranordnung an einem metallischen Bestandteil vermieden werden. Die Aussenfläche des Mantels, die im vorderen Geschossteil durch die Geschossspitze gebildet ist, wird im hinteren Geschossteil aus der metallischen Geschosshülle gebildet, die sie als solide Befestigungsbasis zur Befestigung des Führungsringes benutzt werden kann. Die rückwärtige, durch die Geschosshülle berandete Öffnung des Mantels ist mittels eines Dichtungskörpers verschlossen, der sich ins Innere des Mantels erstreckt und dabei den Geschosskern zum Teil umgibt.On the new floor, the floor body is designed so that its diameter is from front to back constant or increasing, but in any case not decreasing, so that the projectile core can be inserted into the prefabricated casing from behind. Of the Sheath consists of a generally metallic shell and a bullet tip made of a sprayable, hardened material, preferably plastic, which is injected onto the shell. There is a recess inside the top of the projectile for the projectile core and a centering arrangement for guiding and fixing of the projectile body is provided. The centering arrangement is therefore on the new floor provided on an injection molded component, just at the top of the projectile that the high cost of manufacturing the centering assembly on a metallic component be avoided. The outer surface of the jacket, that in the front part of the storey is formed by the bullet tip, in the rear part of the bullet from the metallic Projectile shell formed, which they as a solid mounting base for attaching the guide ring can be used. The rear, bordered by the shell The opening of the jacket is closed by means of a sealing body that extends into the interior extends of the jacket and thereby partially surrounds the projectile core.

Da der Führungsring nicht am Dichtungskörper befestigt werden muss, wird vorzugsweise nicht nur die Geschossspitze sondern auch der Dichtungskörper aus Kunststoff hergestellt und im allgemeinen nach dem Bestücken des Mantels angespritzt, so dass Fertigung und Montage in einem Arbeitsgang durchgeführt werden. Mit einem angespritzten Dichtungskörper erhält man ein besonders günstiges Geschoss, da durch dadurch der Geschosskörper in axialer Richtung vollständig fixiert wird, ohne dass beispielsweise eine hochpräzise mechanische Fertigung durchzuführen ist bzw. auch in Fällen, in denen der Geschosskern mit einer verhältnismässig grossen Toleranz hergestellt ist. Since the guide ring does not have to be attached to the sealing body, it is preferred not only the bullet tip but also the sealing body made of plastic and generally molded after fitting the jacket, so that manufacturing and Assembly can be carried out in one operation. With a molded sealing body you get a particularly inexpensive projectile, because this means the projectile body is completely fixed in the axial direction without, for example, a high-precision mechanical production is to be carried out or also in cases where the storey core is manufactured with a relatively large tolerance.

Bei der Herstellung des Geschosses wird in einem ersten Schritt die Geschossspitze an die Geschosshülle gespritzt und in einem zweiten Schritt der Geschosskörper von hinten bis zu einem Anschlag in die Zentrieranordnung geschoben. In einem dritten Schritt wird der Dichtungskörper angebracht. Dieser wird vorzugsweise durch Einbringen von spritzbarem Material ins Innere der Geschosshülle bzw. des Mantels hergestellt, wonach der Geschosskörper vorne am Anschlag, seitlich an seiner Umfangsfläche und hinten an seiner Endfläche vollständig vom Spritzmaterial der Geschossspitze und des Dichtungskörpers umgeben ist.The first step in the manufacture of the projectile is the projectile tip the projectile shell is injected and in a second step the projectile body from behind pushed into the centering arrangement up to a stop. In a third step the seal body attached. This is preferably done by introducing sprayable Material is made inside the shell or shell, after which the projectile body on the front of the stop, on the side of its peripheral surface and on the back of its End surface completely from the spray material of the bullet tip and the sealing body is surrounded.

Die mit der Erfindung erzielten Vorteile sind darin zu sehen, dass im gleichen Mantel ein- oder mehrteilige Geschosskörper verschiedenster Art und Grösse verwendet werden können, wobei ausserdem das vorgeschlagene Fabrikationsverfahren einfach und zeitsparend ist, da im Gegensatz zum Geschoss der FR-2 238 137 nicht nur die Geschossspitze an und für sich sondern auch die Zentrieranordnung aus spritzbarem Material hergestellt ist, so dass günstige Herstellungskosten erzielbar sind. Wenn auch der Dichtungskörper aus spritzbarem Material hergestellt wird, was ohne weiteres möglich und sogar empfehlenswert ist, werden die Herstellungskosten weiter reduziert.The advantages achieved with the invention can be seen in the fact that single or multi-part projectile bodies of various types and sizes can be used in the same casing, the proposed manufacturing method also being simple and time-saving since, in contrast to the projectile of FR-2 238 137, not only the projectile tip is made in and of itself, but also the centering arrangement is made of sprayable material, so that low manufacturing costs can be achieved. If the sealing body is also made of sprayable material, which is easily possible and even recommended, the manufacturing costs are further reduced.

Die Fig. 1 bis 4 zeigen ein Geschoss mit einem Mantel 1, der aus einer Geschosshülle 2 und einer mit dieser fest verbundenen Geschossspitze 3 gebildet ist. Die Geschossspitze 3, die aus einem gespritzen Material, vorzugsweise aus einem hochwarmfesten, faserverstärktem thermoplastischen Kunststoff, besteht, wird in einem ersten Schritt eines Fabrikationsverfahrens auf die Geschosshülle 2 gespritzt, wobei sie in vordere Geschosshüllen-Rillen 4, die im Inneren der Geschosshülle 2 angeordnet sind, eindringt und auf diese Weise verankert wird. Die Geschossspitze 3 weist eine zur Geschosslängsachse koaxiale zylindrische Ausnehmung 5 für die Aufnahme und Zentrierung eines Geschosskörpers 6 auf. In der Ausnehmung 5 sind vier um 90° versetzte Nuten 7 vorgesehen, deren Bodenfläche 8 teilkreisförmig konzentrisch zur Bohrung 5 gewölbt ist. An der Rückseite der Geschossspitze 3 sind am Rand der Ausnehmung 5 vier Stege 9 angeordnet, die gegen die Nuten 7 um 90° versetzt sind und die einen Abstand voneinander haben, der gleich gross wie die Breite der Nuten 7 ist. Die Stege 9 sind im Querschnitt bogenförmig und weisen eine Dicke auf, die der Tiefe der Nuten 7 entspricht. Die Ausnehmung 5 setzt sich in Richtung zur Geschossspitze in einer zylindrischen Ausnehmungsverlängerung 10 fort, die ebenfalls koaxial zur Geschosslängsachse verläuft und einen kleineren Durchmesser als die Ausnehmung 5 hat und zusammen mit der Ausnehmung 5 eine Schulter, welche dazu bestimmt ist, einen axialen Anschlag 11 für den Geschosskern zu bilden. 1 to 4 show a projectile with a casing 1, which is formed from a projectile casing 2 and a projectile tip 3 firmly connected to this. The projectile tip 3 , which consists of an injection-molded material, preferably a high-temperature-resistant, fiber-reinforced thermoplastic, is injected onto the projectile casing 2 in a first step of a manufacturing process, wherein it is arranged in front projectile casing grooves 4 , which are arranged inside the projectile casing 2 are, penetrates and is anchored in this way. The projectile tip 3 has a cylindrical recess 5, which is coaxial with the longitudinal axis of the projectile, for receiving and centering a projectile body 6 . In the recess 5 there are four grooves 7 offset by 90 °, the bottom surface 8 of which is curved in a partially circular manner concentrically with the bore 5 . On the back of the projectile tip 3 , four webs 9 are arranged on the edge of the recess 5 , which are offset by 90 ° against the grooves 7 and which are at a distance from one another which is the same size as the width of the grooves 7 . The webs 9 are arcuate in cross section and have a thickness which corresponds to the depth of the grooves 7 . The recess 5 continues in the direction of the projectile tip in a cylindrical recess extension 10 which also runs coaxially to the longitudinal axis of the projectile and has a smaller diameter than the recess 5 and together with the recess 5 a shoulder which is intended to provide an axial stop 11 for to form the floor core.

Der Geschosskörper 6, der gelegentlich auch als Geschosskern oder Penetrator bezeichnet wird, weist gemäss der ersten beispielsweisen Ausführung der Fig. 1 bis 4 eine zylindrische Form mit an den Enden abgerundeten Geschosskörper-Kanten 12, 13 auf. Der Geschosskörper 6 hat praktisch den gleichen Durchmesser wie die Ausnehmung 5 und ist an seinem Äusseren mit umlaufenden Geschosskörper-Rillen 14 versehen. In einem zweiten Schritt des Fabrikationsverfahrens wird der Geschosskörper 6 durch die an der Rückseite noch offene Geschosshülle 2, die in Fig. 3 dargestellt ist, entlang der Stege 9 in die Ausnehmung 5 bis zum Anschlag 11 an der hierfür vorgesehenen Schulter geschoben und in dieser Stellung zentriert gehalten.The projectile body 6 , which is also sometimes referred to as a projectile core or penetrator, has, according to the first exemplary embodiment of FIGS. 1 to 4, a cylindrical shape with rounded projectile body edges 12 , 13 at the ends. The projectile body 6 has practically the same diameter as the recess 5 and is provided on its exterior with circumferential projectile body grooves 14 . In a second step of the manufacturing process, the projectile body 6 is pushed through the projectile casing 2 , which is still open on the rear side, which is shown in FIG. 3 , along the webs 9 into the recess 5 up to the stop 11 on the shoulder provided for this purpose and in this position kept centered.

Ein Dichtungskörper 15, der aus dem gleichen spritzbaren Material wie die Geschossspitze 3, also vorzugsweise aus thermoplastischem Kunststoff, besteht, wird in einem dritten Schritt des Fabrikationsverfahrens durch Einspritzen des spritzbaren Materials in die an der Rückseite noch offene Geschosshülle 2 gebildet. Hierbei dringt das spritzbare Material auch in die Nuten 7 und zwischen die Stege 9 der Geschossspitze 3, sowie in die Geschosskörper-Rillen 14 am Geschosskörper 6. Der Geschosskörper 6 ist danach vorne an der den Anschlag 11 bildenden Schulter, seitlich und hinten vollständig vom spritzbaren bzw. gespritzten Material umgeben und fest im Mantel 1 verankert. Das spritzbare Material dringt ebenfalls in weitere, an der Innenseite der Geschosshülle 2 vorgesehene mittlere Geschosshüllen-Rillen 16 und in hintere Geschosshüllen-Rillen 17 ein, wodurch der Dichtungskörper 15 fest in der Geschosshülle 2 verankert wird, wie dies aus den Fig. 1 und 2 ersichtlich ist.A sealing body 15, which consists of the same sprayable material as the projectile tip 3 , that is to say preferably of thermoplastic material, is formed in a third step of the manufacturing process by injecting the sprayable material into the projectile shell 2, which is still open on the rear. Here, the sprayable material also penetrates into the grooves 7 and between the webs 9 of the projectile tip 3 and into the projectile body grooves 14 on the projectile body 6 . The projectile body 6 is then completely surrounded by the sprayable or sprayed material at the front on the shoulder forming the stop 11 , laterally and at the rear, and is firmly anchored in the jacket 1 . The sprayable material also penetrates into further middle projectile casing grooves 16 provided on the inside of the projectile casing 2 and into rear projectile casing grooves 17, as a result of which the sealing body 15 is firmly anchored in the projectile casing 2 , as is shown in FIGS. 1 and 2 can be seen.

Im hinteren Bereich der Geschosshülle 2 sind, wie an sich bekannt, eine Hülsen-Umfangsnut 18 für die Befestigung einer nicht dargestellten Patronenhülse und eine Ring-Umfangsnut 19 vorgesehen, wobei in der Ring-Umfangsnut ein Führungsring 20 für die Führung des Geschosses in einem Waffenrohr angebracht ist.In the rear area of the projectile shell 2 , as is known per se, a sleeve circumferential groove 18 for fastening a cartridge case, not shown, and an annular circumferential groove 19 are provided, a guide ring 20 for guiding the projectile in a weapon barrel in the circumferential ring groove is appropriate.

Gemäss Fig. 5 besteht der Geschosskörper der zweiten Ausführung aus mehreren Teilgeschosskörpern 21 bis 25. Wie als Beispiel dargestellt, können die Teilgeschosskörper 21 bis 25 aus in Geschosslängsrichtung aneinandergereihten zylinderartigen Pillen bestehen, die ebenso wie anhand der Fig. 1 vorstehend beschrieben im zweiten Fabrikationsschritt in die aus der Ausnehmung 5 und den Stegen 9 gebildeten Zentrierung eingeschoben und bei der Bildung des Dichtungskörpers 15 im dritten Schritt des Fabrikationsverfahrens vom spritzbaren Material umgeben und fest verankert werden. Es können jedoch auch Teilgeschosskörper anderer Form und Anzahl verwendet werden. Auch die Art bzw. der Werkstoff der Teilgeschosskörper kann generell oder innerhalb eines Geschosses verschieden sein. So kann beispielsweise für die Teilgeschosskörper 21 und 24 frangibles Schwermetall, für die Teilgeschosskörper 22 und 25 duktiles Schwermetall und für den Teilgeschosskörper 23 ein Brandsatz verwendet werden. 5 , the projectile body of the second embodiment consists of several partial projectile bodies 21 to 25 . As shown as an example, the partial storey bodies 21 to 25 can consist of cylinder-like pills lined up in the longitudinal direction of the storey, which, as described above with reference to FIG. 1, are inserted in the second manufacturing step into the centering formed by the recess 5 and the webs 9 and in the formation of the In the third step of the manufacturing process, the sealing body 15 is surrounded by the sprayable material and firmly anchored. Partial storey structures of different shapes and numbers can also be used. The type or the material of the partial storey body can also be different in general or within one storey. For example, frangible heavy metal can be used for the sub-storey elements 21 and 24, ductile heavy metal for the sub-storey elements 22 and 25 and a fire set for the sub-storey element 23 .

Gemäss Fig. 5 ist ein Führungsring 31 ist in einer Umfangsnut 32 einer Geschosshülle 30 eingebettet. Der Führungsring 31 wird im dritten Schritt des Fabrikationsverfahrens integral mit dem Dichtungskörper 33 durch Einspritzen des hochwarmfesten faserverstärkten thermoplastischen Kunststoffes in die an der Rückseite noch offene Geschosshülle 30 gebildet. Für den Austritt des spritzbaren Materials aus der Geschosshülle 30 in die Umfangsnut 32 sind in dieser mehrere radial verlaufende Durchbrüche 34 vorgesehen. Mit einem derart hergestellten und befestigten Führungsring 31 können die Fabrikationskosten des Geschosses gesenkt und der beim Abschuss auftretende Verschleiss im Waffenrohr vermindert werden. 5 , a guide ring 31 is embedded in a circumferential groove 32 of a projectile casing 30 . In the third step of the manufacturing process, the guide ring 31 is formed integrally with the sealing body 33 by injecting the high-temperature, fiber-reinforced thermoplastic material into the projectile casing 30, which is still open at the rear. A plurality of radially extending openings 34 are provided in the circumferential groove 32 for the exit of the sprayable material from the projectile shell 30 . With a guide ring 31 produced and fastened in this way, the manufacturing costs of the projectile can be reduced and the wear in the weapon barrel that occurs when it is fired can be reduced.

In Fig. 6 sind zwei Halbquerschnitte a, b entlang den Linien VI-VI und VI'-VI' in Fig. 5 durch das Geschoss dargestellt. FIG. 6 shows two half cross sections a, b along the lines VI-VI and VI'-VI 'in FIG. 5 through the projectile.

Fig. 7 zeigt eine Variante zur Form der bei Fig. 5 dargestellten Teilgeschosskörper 21 bis 25. Zur noch exakteren Zentrierung weisen dabei die einzelnen Teilgeschosskörper 21 bis 25 einerseits an den Stirnflächen zapfenartige Fortsätze 27 und die Abschlussflächen entsprechende Vertiefungen 26 auf, in welche die zapfenartigen Fortsätze hineinragen. Diese Fortsätze 27 und auch die entsprechenden Vertiefungen 26 können einfach gefertigt werden und erlauben eine problemlose Montage mit einwandfreier gegenseitiger Zentrierung. Diese Zentrierung ist um so notwendiger, je besser diese Geschosse ausgewuchtet sein müssen. FIG. 7 shows a variant of the shape of the partial storey elements 21 to 25 shown in FIG. 5 . For even more precise centering, the individual partial storey elements 21 to 25 have peg-like extensions 27 on the end faces and corresponding recesses 26 into the end faces, into which the peg-like extensions project. These extensions 27 and also the corresponding recesses 26 can be easily manufactured and allow problem-free assembly with perfect mutual centering. This centering is all the more necessary the better these floors have to be balanced.

Fig. 8 zeigt eine weitere Variante der Form der in Fig. 5 dargestellten Teilgeschosskörper 21 bis 25. Dabei sind an den Endflächen der pillenförmigen Teilgeschosskörper 21 bis 25 zapfenartige Fortsätze 27A vorgesehen, die in an den Stirnflächen der folgenden Pillen vorgesehenen Vertiefungen 26A eingreifen. FIG. 8 shows a further variant of the shape of the partial storey elements 21 to 25 shown in FIG. 5 . In this case, on the end faces of the pill-shaped partial storey bodies 21 to 25, peg-like extensions 27A are provided which engage in depressions 26A provided on the end faces of the following pills.
