Definitions
- the invention relates to a projectile with a projectile casing, in which an explosive charge surrounding a fragmentation casing is arranged, wherein the fragmentation casing is fixedly connected to the projectile casing, for example, and the projectile for igniting the explosive charge comprises a preferably adjustable (first) ignition device adjacent to the explosive charge on the rear side ,
- Shrapnel projectiles are usually constructed in such a way that they allow a targeted strong fragmentation effect in closed rooms or in a free landscape. It is therefore not possible with known fragmentation projectiles to use them even if the requirement arises from the respective combat situation that no splinters act on the corresponding target, but only the pressure waves produced during the explosion are to be exploited. Such a situation may occur, for example, when a terrorist group is to be fought with an anti-tank projectile and the tank commander immediately before the firing of the projectile finds that near the terrorist group is a kindergarten, so that the fragments of the projectile also a large number of uninvolved persons would endanger.
- a fragmentation warhead for controlling technical targets is already known with an explosive charge surrounded by a shatter-forming sheath which can be reduced or destroyed in its effect by means of one or more low-power detonative means. That is, in addition to the detonative or deflagrative initiation of the explosive charge, this also has effective means for the controlled power reduction of the fragment-forming shell of the warhead.
- the explosive charge is surrounded by a thin jacket, on the outside of a circumferential fragment-forming shell is provided, which can be moved or rotated on the mantle. Due to the displaceability of the shell, the power of fragmentation is influenced in such a way that splinter formation occurs only in this part. The same can be achieved by means of rotation of the sleeve.
- a disadvantage is the complicated structure and a necessary additional space.
- the invention has for its object to provide a projectile which acts either as a fragmentation projectile or as a projectile with pressure wave formation.
- a discharge charge and an axially displaceable against the splinter shell explosive charge are arranged in the projectile, wherein the explosive charge by means of the ejection charge at least as far pushed out of the projectile casing that it no longer acts in an explosion on the firmly connected to the projectile shell splinter shell.
- the ejection charge If the ejection charge is not activated in such a projectile, it acts as a pure splinter projectile, since the explosive charge - as in known projectiles - is within the fragmentation shell. If, on the other hand, the ejection charge is activated prior to the ignition of the explosive charge, the explosive charge is at least partially pushed out of the projectile envelope and thus out of the splinter shell, and the subsequently activated explosive charge does not cause the splinter shell remaining in the remaining projectile to split apart, so that in this case only the Pressure waves of the explosive charge in the target area come into effect.
- the explosive charge Since the explosive charge must have a certain minimum rigidity due to the acceleration forces occurring when launching the projectile, it is provided in the abovementioned projectile to arrange the explosive charge within a metal jacket (for example a copper jacket). However, such a metal jacket causes unwanted splinters to be generated when the explosive charge is ignited even when the explosive charge has already been pushed out of the splinter shell.
- a metal jacket for example a copper jacket
- the invention is based essentially on the idea of wrapping the explosive charge with a jacket which unfolds little or no splintering effect when the explosive charge is ignited.
- a shell for the explosive charge a molded part made of plastic (preferably made of a glass or carbon fiber reinforced plastic) or a light metal (for example, die-cast aluminum) is used.
- the molded part with a plurality of evenly distributed over the circumference arranged and each is provided in the direction of the longitudinal axis extending stiffening ribs.
- the annular flange part may be a metal ring, the inner wall of which has on its side facing the ignition device at least one undercut, which is frictionally enclosed by the molded part.
- the metal ring in a production of the respective molded part by injection molding of the metal ring can be encapsulated in the manufacture of the molded part of the plastic or light metal at the same time.
- an O-ring may also be arranged on the circumference in a groove-shaped recess which, in the case of the production of the molded part, is injection-molded directly onto the molded part by means of an injection process.
- the projectile may, for example, be a wing-stabilized tank projectile with a caliber ⁇ 100 mm (for example a caliber of 120 mm).
- Fig.1 is with 1 a large caliber, wing stabilized projectile (fragmentation warhead with a caliber of eg 120 mm), which can be fired from a tank cannon.
- the wings are not shown for clarity.
- the projectile 1 has a projectile casing 2, within which an explosive charge 3 is arranged.
- the explosive charge 3 is surrounded by a molded part 4 of a glass or carbon fiber reinforced plastic, which is located within a splitter shell 5 connected to the projectile casing 2.
- the splinter shell 5 with the projectile casing 2 for example, over several evenly distributed over the circumference arranged Stahlkerbturne (not shown) firmly connected.
- the housing 7 of the ignition device 6 and the explosive charge 3 surrounding molding 4 are positively connected with each other and form a structural unit.
- a non-positively attached to the mold part 4 and designed as a metal ring flange 8 is provided, which has distributed over the circumference arranged threaded holes 17.
- the inner wall 9 of the flange 8 on its side facing the ignition 6 side undercuts 10, which are enclosed (for example by injection molding) of the fiber-reinforced plastic material of the molded part 4.
- the assembly consisting of the molded part 4 with explosive charge 3 and the ignition device 6 is fixed within the projectile casing 2, for example, by the fact that the ignition device 6 is glued or pressed into the projectile casing 2.
- the assembly consisting of the molded part 4 and the ignition device 6 is (after overcoming the fixing forces caused by the gluing or pressing) in the axial direction to the rear 11 of the projectile 1 slidably mounted in the projectile casing 2.
- the displacement is effected by means of a discharge charge 12, which is arranged in an annular, the splinter shell 5 outside surrounding cavity 13.
- the cavity 13 is bounded on the rear side by a radially projecting annular surface 14 of the housing 7 of the ignition device 6.
- the molded part 4 is provided with eight, uniformly distributed over the circumference of the molded part 4 and each extending in the direction of the longitudinal axis 100 extending stiffening ribs 15 ( Figure 3 ).
- FIGS. 2 and 4 can be removed, the molding 4 in its front part on the outside a circumferential groove-shaped recess 18 for an O-ring, not shown.
- the projectile 1 is to act as a fragmentary projectile in a predetermined target area, the projectile 1 is fired in the direction of the target area without additional information having been transmitted via an ignition of the ejection charge 12 to the ignition device 6.
- the ignition device 6 and from this the explosive charge 3 is activated so that the fragmentation shell 5 ruptures and splinters are thrown radially into the target area at high speed.
- the target area is damaged as little as possible by splinters and only the pressure wave generated by the activation of the explosive charge 3 comes into effect, an additional information is entered by the respective tank commander in the adjustable ignition device 6, so that a short time before the actual ignition of the explosive charge 3 the ejection charge 12 is activated. Due to the resulting propellant charge gases from the explosive charge 3 containing mold part 4 and the ignition device 6 existing unit is ejected against the firing direction in the target area and the fragmentation shell 5 remains in the remaining floor. Only after the ejection of the explosive charge 3 from the projectile casing 2, the explosive charge 3 is then ignited by the associated with her first ignition device 6, so that the forming Pressure waves no longer act on the splinter shell 5.
- the plastic splinters produced in this case have only a short range and a relatively low kinetic energy, so that they usually do not damage the target damaging effect.
- the invention is not limited to the embodiment described above.
- the molded part 4 for example, consist of a light metal, since the resulting in the activation of the explosive charge light metal splitter also have a steel or copper splinters much lower range and lower kinetic energy.

Description
Die Erfindung betrifft ein Geschoss mit einer Geschosshülle, in welcher eine von einer Splitterhülle umgebende Sprengladung angeordnet ist, wobei die Splitterhülle mit der Geschosshülle beispielsweise fest verbunden ist, und das Geschoss zur Zündung der Sprengladung eine der Sprengladung heckseitig benachbarte vorzugsweise tempierbare (erste) Zündeinrichtung umfasst.The invention relates to a projectile with a projectile casing, in which an explosive charge surrounding a fragmentation casing is arranged, wherein the fragmentation casing is fixedly connected to the projectile casing, for example, and the projectile for igniting the explosive charge comprises a preferably adjustable (first) ignition device adjacent to the explosive charge on the rear side ,
Splittergeschosse sind üblicherweise derart aufgebaut, dass sie eine gezielte starke Splitterwirkung in geschlossenen Räumen oder in freier Landschaft ermöglichen. Es ist daher mit bekannten Splittergeschossen nicht möglich, diese auch dann einzusetzen, wenn sich aus der jeweiligen Gefechtssituation die Forderung ergibt, dass auf das entsprechende Ziel keine Splitter einwirken, sondern lediglich die bei der Explosion entstehenden Druckwellen ausgenutzt werden sollen. Eine derartige Situation kann beispielsweise dann eintreten, wenn eine Terrorgruppe mit einem als Splittergeschoss ausgebildeten Panzergeschoss bekämpft werden soll und der Panzerkommandant unmittelbar vor dem Abfeuern des Geschosses feststellt, dass sich in der Nähe der Terrorgruppe ein Kindergarten befindet, so dass die Splitter des Geschosses auch eine große Anzahl unbeteiligter Personen gefährden würde.Shrapnel projectiles are usually constructed in such a way that they allow a targeted strong fragmentation effect in closed rooms or in a free landscape. It is therefore not possible with known fragmentation projectiles to use them even if the requirement arises from the respective combat situation that no splinters act on the corresponding target, but only the pressure waves produced during the explosion are to be exploited. Such a situation may occur, for example, when a terrorist group is to be fought with an anti-tank projectile and the tank commander immediately before the firing of the projectile finds that near the terrorist group is a kindergarten, so that the fragments of the projectile also a large number of uninvolved persons would endanger.
Aus der
Der Erfindung die Aufgabe zugrunde, ein Geschoss zu schaffen, welches wahlweise als Splittergeschoss oder als Geschoss mit Druckwellenbildung wirkt.The invention has for its object to provide a projectile which acts either as a fragmentation projectile or as a projectile with pressure wave formation.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.
In einer parallelen Patentanmeldung der Anmelderin wird bereits ein Geschoss vorgeschlagen, welches wahlweise als Splittergeschoss oder als Geschoss einsetzbar ist, bei dem nur die Wirkung der bei der Explosion der Sprengladung entstehenden Druckwellen ausgenutzt werden kann.In a parallel patent application of the applicant, a projectile is already proposed, which can be used either as a fragmentation projectile or as a projectile which only the effect of resulting in the explosion of the explosive charge pressure waves can be exploited.
Hierzu sind in dem Geschoss eine Ausstoßladung sowie eine axial gegenüber der Splitterhülle verschiebbare Sprengladung angeordnet, wobei die Sprengladung mittels der Ausstoßladung mindestens so weit aus der Geschosshülle herausschiebbar ist, dass sie bei einer Explosion nicht mehr auf die fest mit der Geschosshülle verbundene Splitterhülle wirkt.For this purpose, a discharge charge and an axially displaceable against the splinter shell explosive charge are arranged in the projectile, wherein the explosive charge by means of the ejection charge at least as far pushed out of the projectile casing that it no longer acts in an explosion on the firmly connected to the projectile shell splinter shell.
Wird bei einem derartigen Geschoss die Ausstoßladung nicht aktiviert, wirkt es als reines Splittergeschoss, da sich die Sprengladung - wie bei bekannten Geschossen - innerhalb der Splitterhülle befindet. Wird hingegen die Ausstoßladung vor der Zündung der Sprengladung aktiviert, so wird zunächst die Sprengladung mindestens teilweise aus der Geschosshülle und damit aus der Splitterhülle herausgeschoben, und die anschließend aktivierte Sprengladung bewirkt kein Auseinanderreißen der in dem Restgeschoss verbleibenden Splitterhülle, so dass in diesem Fall lediglich die Druckwellen der Sprengladung in dem Zielgebiet zur Wirkung kommen.If the ejection charge is not activated in such a projectile, it acts as a pure splinter projectile, since the explosive charge - as in known projectiles - is within the fragmentation shell. If, on the other hand, the ejection charge is activated prior to the ignition of the explosive charge, the explosive charge is at least partially pushed out of the projectile envelope and thus out of the splinter shell, and the subsequently activated explosive charge does not cause the splinter shell remaining in the remaining projectile to split apart, so that in this case only the Pressure waves of the explosive charge in the target area come into effect.
Da die Sprengladung aufgrund der beim Abschuss des Geschosses auftretenden Beschleunigungskräfte eine gewisse Mindeststeifigkeit aufweisen muss, ist bei dem vorstehend erwähnten Geschoss vorgesehen, die Sprengladung innerhalb eines Metallmantels (beispielsweise eines Kupfermantels) anzuordnen. Ein derartiger Metallmantel bewirkt allerdings, dass bei Zündung der Sprengladung auch dann unerwünschte Splitter erzeugt werden, wenn die Sprengladung bereits aus der Splitterhülle herausgeschoben wurde.Since the explosive charge must have a certain minimum rigidity due to the acceleration forces occurring when launching the projectile, it is provided in the abovementioned projectile to arrange the explosive charge within a metal jacket (for example a copper jacket). However, such a metal jacket causes unwanted splinters to be generated when the explosive charge is ignited even when the explosive charge has already been pushed out of the splinter shell.
Ausgehend von dem vorstehend beschriebenen, bisher nicht veröffentlichten Geschoss beruht die Erfindung im Wesentlichen auf dem Gedanken, die Sprengladung mit einem Mantel zu umhüllen, der bei einer Zündung der Sprengladung keine oder nur eine geringe Splitterwirkung entfaltet. Als Mantel für die Sprengladung wird ein Formteil aus Kunststoff (vorzugsweise aus einem glas- oder kohlefaserverstärkten Kunststoff) oder aus einem Leichtmetall (beispielsweise aus Aluminiumdruckguss) verwendet.Based on the above-described, previously unpublished bullet, the invention is based essentially on the idea of wrapping the explosive charge with a jacket which unfolds little or no splintering effect when the explosive charge is ignited. As a shell for the explosive charge, a molded part made of plastic (preferably made of a glass or carbon fiber reinforced plastic) or a light metal (for example, die-cast aluminum) is used.
Um eine ausreichend hohe Steifigkeit der Sprengladung beim Abschuss des erfindungsgemäßen Geschosses zu gewährleisten, hat es sich als vorteilhaft erwiesen, wenn das Formteil mit mehreren, gleichmäßig über den Umfang verteilt angeordneten und sich jeweils in Richtung der Längsachse erstreckenden Versteifungsrippen versehen ist.In order to ensure a sufficiently high rigidity of the explosive charge when launching the projectile according to the invention, it has proved to be advantageous if the molded part with a plurality of evenly distributed over the circumference arranged and each is provided in the direction of the longitudinal axis extending stiffening ribs.
Zur optimalen Anbindung des die Sprengladung enthaltenden Formteiles an die Zündeinrichtung hat es sich als zweckmäßig erwiesen, das Formteil mit der darin befindlichen Sprengladung mit Hilfe eines ringförmigen Flanschteiles mit der Zündeinrichtung kraftschlüssig zu verbinden. Dabei kann es sich bei dem ringförmigen Flanschteil um einen Metallring handeln, dessen Innenwand auf ihrer der Zündeinrichtung zugewandten Seite mindestens eine Hinterschneidung aufweist, welche kraftschlüssig von dem Formteil umschlossen ist. Insbesondere bei einer Herstellung des jeweiligen Formteiles durch Spritzgießen kann der Metallring bei dem Herstellen des Formteiles gleichzeitig von dem Kunststoff oder Leichtmetall mit umspritzt werden.For optimum connection of the explosive charge-containing molded part to the ignition device, it has proven expedient to connect the molded part with the explosive charge therein by means of an annular flange with the ignition frictionally. In this case, the annular flange part may be a metal ring, the inner wall of which has on its side facing the ignition device at least one undercut, which is frictionally enclosed by the molded part. In particular, in a production of the respective molded part by injection molding of the metal ring can be encapsulated in the manufacture of the molded part of the plastic or light metal at the same time.
Zusätzlich zur axialen Versteifung des Formteiles mittels Längsrippen kann auch noch ein O-Ring umfangseitig in einer nutenförmigen Ausnehmung angeordnet sein, der im Falle der Herstellung des Formteiles durch einen Spritzvorgang direkt an das Formteil mit angespritzt wird.In addition to the axial stiffening of the molded part by means of longitudinal ribs, an O-ring may also be arranged on the circumference in a groove-shaped recess which, in the case of the production of the molded part, is injection-molded directly onto the molded part by means of an injection process.
Bei dem Geschoss kann es sich beispielsweise um ein flügelstabilisiertes Panzergeschoss mit einem Kaliber ≥ 100 mm (z.B. mit einem Kaliber von 120 mm) handeln.The projectile may, for example, be a wing-stabilized tank projectile with a caliber ≥ 100 mm (for example a caliber of 120 mm).

In
Das Geschoss 1 besitzt eine Geschosshülle 2, innerhalb welcher eine Sprengladung 3 angeordnet ist. Die Sprengladung 3 ist von einem Formteil 4 aus einem glas- oder kohlefaserverstärkten Kunststoff umgeben, welches sich innerhalb einer mit der Geschosshülle 2 verbundenen Splitterhülle 5 befindet. Dabei ist die Splitterhülle 5 mit der Geschosshülle 2 beispielsweise über mehrere, gleichmäßig über den Umfang verteilt angeordnete Stahlkerbstifte (nicht dargestellt) fest verbunden.The projectile 1 has a
Außerdem ist zur Zündung der Sprengladung 3 in der Geschosshülle 2 eine der Sprengladung 3 heckseitig benachbarte tempierbare Zündeinrichtung 6 angeordnet (aus Gründen einer besseren Übersicht ist in
Das Gehäuse 7 der Zündeinrichtung 6 und das die Sprengladung 3 umgebende Formteil 4 sind kraftschlüssig miteinander verbunden und bilden eine Baueinheit. Hierzu ist ein an dem Formteil 4 kraftschlüssig befestigtes und als Metallring ausgebildetes Flanschteil 8 vorgesehen, das über den Umfang verteilt angeordnete Gewindebohrungen 17 aufweist. Mit Hilfe von Schrauben 16, deren Schaft durch das Gehäuse 7 der Zündeinrichtung hindurchgeführt und die vorderseitig in die Gewindebohrungen 17 hineingedreht sind, sind die Zündeinrichtung 6 und das die Sprengladung 3 enthaltende Formteil 4 miteinander verbunden.The housing 7 of the

Die aus dem Formteil 4 mit Sprengladung 3 und der Zündeinrichtung 6 bestehende Baueinheit wird innerhalb der Geschosshülle 2 beispielsweise dadurch fixiert, dass die Zündeinrichtung 6 in die Geschosshülle 2 eingeklebt oder eingepresst wird.The assembly consisting of the
Die aus dem Formteil 4 und der Zündeinrichtung 6 bestehende Baueinheit ist (nach Überwindung der durch die Klebung oder Pressung bedingten Fixierkräfte) in axialer Richtung zum Heck 11 des Geschosses 1 hin verschiebbar in der Geschosshülle 2 gelagert. Dabei wird die Verschiebung mittels einer Ausstoßladung 12 bewirkt, die in einem ringförmigen, die Splitterhülle 5 außenseitig umgebenden Hohlraum 13 angeordnet ist. Der Hohlraum 13 wird heckseitig durch eine radial vorstehende Kreisringfläche 14 des Gehäuses 7 der Zündeinrichtung 6 begrenzt.The assembly consisting of the
Zur Erhöhung der Steifigkeit des Formteiles 4, und damit der Sprengladung 3, ist das Formteil 4 mit acht, gleichmäßig über den Umfang des Formteiles 4 verteilt angeordneten und sich jeweils in Richtung der Längsachse 100 erstreckenden Versteifungsrippen 15 versehen (
Wie den
Soll das erfindungsgemäße Geschoss 1 in einem vorgegebenen Zielbereich als Splittergeschoss wirken, so wird das Geschoss 1 in Richtung auf den Zielbereich abgefeuert, ohne dass auf die Zündeinrichtung 6 vorher Zusatzinformationen über eine Zündung der Ausstoßladung 12 übertragen wurden.If the projectile 1 according to the invention is to act as a fragmentary projectile in a predetermined target area, the projectile 1 is fired in the direction of the target area without additional information having been transmitted via an ignition of the
Sobald daher ein an dem Geschoss 1 angeordneter Sensor den Zielbereich detektiert, wird die Zündeinrichtung 6 und von dieser die Sprengladung 3 aktiviert, so dass die Splitterhülle 5 aufreißt und Splitter mit hoher Geschwindigkeit radial in den Zielbereich geschleudert werden.Therefore, as soon as a sensor arranged on the projectile 1 detects the target area, the
Soll nun das Zielgebiet möglichst wenig durch Splitter beschädigt werden und lediglich die durch die Aktivierung der Sprengladung 3 erzeugte Druckwelle zur Wirkung kommen, so wird von dem jeweiligen Panzerkommandanten in die tempierbare Zündeinrichtung 6 eine Zusatzinformation eingegeben, so dass kurze Zeit vor der eigentlichen Zündung der Sprengladung 3 die Ausstoßladung 12 aktiviert wird. Durch die dadurch entstehenden Treibladungsgase wird die aus dem die Sprengladung 3 enthaltenden Formteil 4 und der Zündeinrichtung 6 bestehende Baueinheit entgegen der Abschussrichtung in dem Zielgebiet ausgestoßen und die Splitterhülle 5 verbleibt in dem Restgeschoss. Erst nach dem Ausstoßen der Sprengladung 3 aus der Geschosshülle 2 wird die Sprengladung 3 dann durch die mit ihr verbundene erste Zündeinrichtung 6 gezündet, so dass die sich ausbildenden Druckwellen nicht mehr auf die Splitterhülle 5 wirken. Die dabei erzeugten Kunststoffsplitter weisen nur eine geringe Reichweite und eine relativ geringe kinetische Energie auf, so dass durch sie eine das Ziel beschädigende Wirkung in der Regel nicht auftritt.If the target area is damaged as little as possible by splinters and only the pressure wave generated by the activation of the
Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So kann das Formteil 4 beispielsweise auch aus einem Leichtmetall bestehen, da die bei der Aktivierung der Sprengladung entstehenden Leichtmetallsplitter ebenfalls eine gegenüber Stahl- oder Kupfersplitter wesentlich geringere Reichweite und geringere kinetische Energie besitzen.Of course, the invention is not limited to the embodiment described above.
