Description

BESCHREIBUNG DESCRIPTION
TreibkäfiggeschossSabot projectile
Die Erfindung betrifft ein Treibkäfiggeschoss mit einem unterkalibrigen Geschosskörper und einem Treibkäfig, der ein heckseitig auf den Geschosskörper wirkendes Treibelement sowie einen sich vorderseitig an das Treibelement anschließenden, segmentierten und im wesentlichen zylinderförmigen Führungskäfig aus Metall umfasst, wobei der Führungskäfig eine sich in axialer Richtung erstreckende zentrale Ausnehmung aufweist, durch welche der Geschosskörper hindurchgeführt ist.The invention relates to a sabot projectile with a subcaliber projectile body and a sabot comprising a rear side acting on the projectile body driving element and a front side of the drive element subsequent, segmented and substantially cylindrical guide cage made of metal, wherein the guide cage extending in the axial direction central Has recess through which the projectile body is passed.
Ein derartiges Treibkäfiggeschoss ist beispielsweise aus der DE 43 30 417 C2 bekannt. Es umfasst einen aus zwei Segmenten bestehenden, im Wesentlichen hohlzylindrischen Führungskäfig aus Aluminium, der einstückig mit einer vorderen Stützwand verbunden ist.Such a sabot projectile is known for example from DE 43 30 417 C2. It comprises a two-segment, substantially hollow cylindrical aluminum guide cage integrally connected to a front support wall.
Nachteilig bei diesem bekannten Treibkäfig ist unter anderem, dass die Herstellung des Führungskäfigs relativ kostenaufwendig ist.A disadvantage of this known sabot, inter alia, that the production of the guide cage is relatively expensive.
Insbesondere faserverstärkte Kunststoffe bilden eine unbekannte Größe hinsichtlich seiner Materialeigenschaften im Temperaturbereich von -46°C bis +710C und hinsichtlich der enormen Belastungsgeschwindigkeiten, die beim Beschuss auf die Kunststoffe einwirken.In particular, fiber-reinforced plastics form an unknown size in terms of its material properties in the temperature range of -46 ° C to +71 0 C and in terms of the enormous load rates acting on the plastics during bombardment.
Der Erfindung liegt die Aufgabe zugrunde, ein Treibkäfiggeschoss der eingangs erwähnten Art anzugeben, welches relativ kostengünstig herstellbar ist, ein geringes Gewicht aufweist und ein gutes Ablösen des Treibkäfigs sicherstellt, sobald das Treibkäfiggeschoss nach Schussabgabe ein entsprechendes Waffenrohr verlassen hat.The invention has for its object to provide a sabot projectile of the type mentioned above, which is relatively inexpensive to produce, has a low weight and ensures good detachment of the sabot, once the sabot projectile has left after firing a corresponding gun barrel.
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.
Die Erfindung beruht im Wesentlichen auf dem Gedanken, dass der Führungskäfig aus einem Hohlzylinder besteht, an dessen Innenwand bevorzugt mehrere voneinander beabstandete, sich sowohl in Richtung der Längsachse des Treibkäfigs als auch in Richtung des Geschosskörpers erstreckende radiale Querrippen angeordnet sein können. Alternativ kann der Hohlzylinder ein aufgeschnittenes Rohr (oder 2 Halbrohre) sein, durch welche die Funktion des Führungskäfigs übernommen werden kann.The invention is based essentially on the idea that the guide cage consists of a hollow cylinder, on the inner wall preferably more of each other spaced, can be arranged both in the direction of the longitudinal axis of the sabot and in the direction of the projectile body extending radial transverse ribs. Alternatively, the hollow cylinder may be a cut-open tube (or 2 half-tubes) through which the function of the guide cage can be assumed.
Die Querrippen versteifen das Gebilde im Öffnungsfall und stützen die Führungsscheibe im Beschleunigungsfall auf kleinerem Durchmesser. Sie können in mindestens einem vorgegebenen Abstand von der Innenwand des Hohlzylinders durch Zwischenwände geschlossen sein, so dass sich mehrere, die zentrale Ausnehmung umschließende und sich in Richtung der Längsachse des Treibkäfigs erstreckende Hohlräume ergeben. Vorzugsweise können die dem Geschosskörper benachbarten Zwischenwände die geschosskör- perseitigen Enden der Querrippen miteinander verbinden.The transverse ribs stiffen the structure in the opening case and support the guide disc in case of acceleration on a smaller diameter. They can be closed in at least a predetermined distance from the inner wall of the hollow cylinder by intermediate walls, so that there are several, the central recess enclosing and extending in the direction of the longitudinal axis of the sabot cavities. Preferably, the intermediate walls adjacent to the projectile body can connect the projectile body-side ends of the transverse ribs to one another.
Insbesondere bei Verwendung von Leichtmetall (beispielsweise einer Aluminium- oder Magnesiumlegierung) ist ein derartiger Führungskäfig besonders kostengünstig herstellbar, wenn es sich um ein durch Strangpressen erzeugtes Profilteil handelt, welches anschließend nachbearbeitet ( das Profil wird beispielsweise ausgedreht) und in axialer Richtung segmentiert oder auch geteilt wird. Außerdem weist der Führungskäfig trotz seines geringen Gewichtes aufgrund der Hohlräume eine für den Abschuss des entsprechenden Treibkäfiggeschosses ausreichende Stabilität und Steifigkeit auf.In particular, when using light metal (for example, an aluminum or magnesium alloy), such a guide cage is particularly inexpensive to produce, if it is a profile produced by extrusion profile part, which is subsequently reworked (the profile is turned off, for example) and segmented in the axial direction or shared becomes. In addition, the guide cage, despite its low weight due to the cavities on a sufficient for the launch of the corresponding sabot projectile stability and rigidity.
Als vorteilhaft hat es sich erwiesen, wenn der Führungskäfig vier, vorzugsweise acht, gleichmäßig über den Umfang verteilt angeordnete, kammerförmige Hohlräume enthält, wobei die Funktion des Führungskäfigs auch bei einem (zwei) halbrunden Hohlraum (Hohlräumen), auch ohne Querrippen, gewährleistet ist.It has proven to be advantageous if the guide cage four, preferably eight, uniformly distributed over the circumference arranged, chamber-shaped cavities, wherein the function of the guide cage even at a (two) semi-circular cavity (cavities), even without transverse ribs, is guaranteed.
Bei einer bevorzugten Ausführungsform der Erfindung besitzt die zentrale Ausnehmung entlang der Längsachse des Treibkäfigs einen im Wesentlichen konstanten Innendurchmesser, der dem maximalen Außendurchmesser des Geschosskörpers, d.h. des Leitwerkes bei einem leitwerkstabilisierten Geschoss, entspricht. Dabei erfolgt die vordere Abstützung des Treibkäfigs an dem Geschosskörper mittels einer an dem Führungskäfig vorderseitig verbundenen, sich radial einwärts erstreckenden segmentierten Stützwand aus Metall, vorzugsweise ebenfalls einer Leichtmetall-Legierung.In a preferred embodiment of the invention, the central recess along the longitudinal axis of the sabot has a substantially constant inner diameter corresponding to the maximum outer diameter of the projectile body, i. of the tail in a tailstock stabilized, corresponds. In this case, the front support of the sabot takes place on the projectile body by means of a front side on the guide cage, radially inwardly extending segmented support wall made of metal, preferably also a light metal alloy.
Bei einer weiteren Ausführungsform der Erfindung ist vorgesehen, dass die zentrale Aus- nehmung entlang der Längsachse des Treibkäfigs einen zur Vorderseite des Führungskäfigs verjüngenden Verlauf besitzt, derart, dass der Innendurchmesser der zentralen Ausnehmung im heckseitigen Bereich des Führungskäfigs dem maximalen Außendurchmesser des Geschosskörpers entspricht und dass der Führungskäfig den Geschosskörper vorderseitig formschlüssig umschließt.In a further embodiment of the invention, it is provided that the central along the longitudinal axis of the sabot has a tapered to the front of the guide cage course, such that the inner diameter of the central recess in the rear-side region of the guide cage corresponds to the maximum outer diameter of the projectile body and that the guide cage surrounds the projectile body form-fit on the front side.
Bei einer derartigen Ausführungsform kann eine separate Stützwand entfallen. Vielmehr kann die Stirnfläche des Führungskäfigs selbst die Funktion der Stützwand übernehmen.In such an embodiment, a separate support wall can be omitted. Rather, the end face of the guide cage itself can take over the function of the support wall.
Zur vorderseitigen Abstützung des Treibkäfigs in einem Waffenrohr kann im vorderen Bereich des Führungskäfigs ein umlaufender, radial nach außen gerichteter Führungsvorsprung vorgesehen werden.For front-side support of the sabot in a gun barrel, a circumferential, radially outwardly directed guide projection can be provided in the front region of the guide cage.
Um die Segmente des Führungskäfigs vorderseitig zusammenzuhalten, kann zusätzlich zur Verwendung eines umfangseitig um die Segmente gelegten Haltebandes der Führungskäfig vorderseitig einen axialen Vorsprung aufweisen, der von einem ringförmigen Gummikörper umschlossen wird, welcher in eine Nut des axialen Vorsprunges und in eine Nut des Geschosskörpers eingreift.To hold the segments of the guide cage on the front side, in addition to the use of a circumferentially around the segments tether holding the guide cage on the front side have an axial projection which is enclosed by an annular rubber body which engages in a groove of the axial projection and in a groove of the projectile body.
Der Grundgedanke hierbei ist also, die Funktionszerlegung des bisherigen Führungskäfigs in mehrere Teile, die vordere Führung des Flugkörpers, die axiale Positionierung dieser Führung, die nach dem Abschuss wieder lösbare Anbindung an die Pusherplatte und axiale Klemmung des Flugkörpers und - eine störungsfreie Ablösung für den Flugkörper durch Verwendung großer, durch Luftdruck belasteter Austrittsflächen.The basic idea here is, the functional separation of the previous guide cage into several parts, the front guide of the missile, the axial positioning of this guide, after the launch again releasable connection to the pusher plate and axial clamping of the missile and - a trouble-free detachment for the missile by using large, by air pressure loaded exit surfaces.
Realisiert werden kann dies in einer ersten Variante mittels zweier Scheiben (vorzugsweise Aluminium) als vordere Führung, zweier Halbprofile (vorzugsweise Aluminium) zur axialen Positionierung und der zwei DB- Halbschalen für die lösbare Anbindung an die Pusherplatte. Diese drei Halbbauteile werden beispielsweise mittels einem 2 - Komponentenkleber verklebt. Über die untere Kante der DB- Halbschalen und mit Hilfe der Klemmelemente wird der Flugkörper dann axial auf der Pusherplatte verklemmt. Die zwei Halbschalen -Baugruppen werden ihrerseits vorne mittels des Kunststoff - Haltebandes und hinten über das Dichtungsband zusammengehalten.This can be realized in a first variant by means of two discs (preferably aluminum) as a front guide, two half-profiles (preferably aluminum) for axial positioning and the two DB half-shells for releasable connection to the pusher plate. These three semi-components are glued for example by means of a 2-component adhesive. Over the lower edge of the DB half-shells and with the help of the clamping elements of the missile is then clamped axially on the pusher plate. The two half-shell assemblies are in turn forward by means of the plastic Holding band and held together behind the sealing tape.
Eine andere Möglichkeit bietet sich durch das Strangpressprofil an. Die dabei hergestellten Halbschalen werden ihrerseits beispielsweise angeschweißt oder alternativ verklebt etc., wodurch die DB- Halbschalen entfallen können. Die Schweißungen etc. werden spätestens beim verlassen des Rohres gebrochen.Another possibility is offered by the extruded profile. The half shells produced in this case are in turn welded, for example, or alternatively glued, etc., whereby the DB shells can be omitted. The welds etc. are broken at the latest when leaving the pipe.
Um die Klemmung des Flugkörpers zu unterstützen, kann vorne über die beiden Halteschalen ein Gummikörper eingebunden werden, der beispielsweise in eine Nut der Profile und eine Nut des Flugkörpers eingreift. Der Gummikörper kann aber alternativ auch anstelle des Haltebandes der anderen Variante in die Führungshalbschalen eingearbeitet werden.To support the clamping of the missile, a rubber body can be integrated in front over the two holding shells, which engages, for example, in a groove of the profiles and a groove of the missile. Alternatively, the rubber body can also be incorporated in the guide half shells instead of the holding band of the other variant.
Ein mit dieser Lösung einhergehender Vorteil ist, dass der Führungskäfig kostengünstig wird. Des Weiteren liefert er eine sehr gute Funktion bei geringen Mengen an Kunststoffen nach dem Beschuss beispielsweise im Gelände. Der Führungskäfig ist Temperatur- und Belastungsstabil und weist ein geringes Gewicht auf.An advantage associated with this solution is that the guide cage becomes inexpensive. Furthermore, it provides a very good function with small amounts of plastics after the bombardment, for example, in the field. The guide cage is temperature and load stable and has a low weight.

Der Fuhrungskafig 7 setzt sich aus zwei, jeweils aus einer Aluminiumlegierung bestehenden, halbschalenformigen Segmenten 9, 10 zusammen Hingegen besteht die Stutzwand 8 aus zwei Halbscheiben 11 , 12, die ebenfalls aus einer Aluminiumlegierung bestehen können Die Befestigung dieser Halbscheiben 11 , 12 an den Segmenten 9, 10 des Fuhrungskafigs 7 erfolgt beispielsweise mittels einer Klebeverbindung Gleiches gilt auch für die heckseitige Befestigung zweier sich an die Segmente 9, 10 des Fuhrungskafigs 7 anschließenden Segmente 13, 14 (Fig 4) des mehrteiligen Treibelementes 5The Fuhrungskafig 7 is composed of two, each consisting of an aluminum alloy, half-shell-shaped segments 9, 10 together, however, the Stutz wall 8 consists of two half-discs 11, 12, which may also consist of an aluminum alloy The attachment of these half-discs 11, 12 to the segments. 9 , 10 of the Fuhrungskafigs 7 takes place for example by means of an adhesive joint The same applies to the rear attachment of two adjoining the segments 9, 10 of the Fuhrungskafigs 7 segments 13, 14 (Figure 4) of the multi-part propellant element fifth
Die aus den Segmenten 9, 11 und 13 bzw 10, 12 und 14 bestehenden 2 Baugruppen des Treibkafigs 4 werden vorderseitig mittels eines Kunststoff-Haltebandes 15 und heckseitig über ein Dichtungsband 16 zusammengehalten.The consisting of the segments 9, 11 and 13 or 10, 12 and 14 2 assemblies of the Treibkafigs 4 are front side by means of a plastic tether 15 and rear side held together by a sealing tape 16.
Bei dem Führungskäfig 7 handelt es sich um ein durch Strangpressen hergestelltes Hohlprofil (Fig.5), welches eine sich in axialer Richtung erstreckende zentrale Ausnehmung 17, durch welche der Geschosskörper 2 hindurchführbar ist, sowie acht die zentrale Ausnehmung umfangseitig umschließende und sich in Richtung der Längsachse 100 des Treibkäfigs 4 erstreckende kammerförmige Hohlräume 18 enthält. Die kammerförmigen Hohlräume 18 sind vorderseitig offen und durch die Elemente 13 und 14 heckseitig geschlossen und werden jeweils durch die Innenwand 103 des Führungskäfigs 7, zwei benachbarte, sich sowohl in Richtung der Längsachse 100 des Treibkäfigs 4 als auch in Richtung des Geschosskörpers 2 erstreckenden Querrippen 104 sowie durch Zwischenwände 105 begrenzt, welche die geschosskörperseitigen Enden der Querrippen 104 miteinander verbinden.The guide cage 7 is a hollow profile (FIG. 5) produced by extrusion, which has a central recess 17 extending in the axial direction through which the projectile body 2 can be passed, and eight peripherally enclosing the central recess and extending in the direction of the central recess Longitudinal axis 100 of the sabot 4 extending chamber-shaped cavities 18 contains. The chamber-shaped cavities 18 are open on the front side and closed at the rear by the elements 13 and 14 and are each formed by the inner wall 103 of the guide cage 7, two adjacent, in the direction of the longitudinal axis 100 of the sabot 4 and in the direction of the projectile body 2 extending transverse ribs 104th and limited by intermediate walls 105 which connect the bullet-side ends of the transverse ribs 104 with each other.
Die zentrale Ausnehmung 17 besitzt entlang der Längsachse 100 des Treibkäfigs 4 einen im Wesentlichen konstanten Innendurchmesser, der dem maximalen Außendurchmesser des Kegelleitwerkes 3 des Geschosskörpers entspricht, so dass der Geschosskörper 2 vorderseitig nicht durch den Führungskäfig 7, sondern lediglich durch die Stützwand 8 gehalten wird.The central recess 17 has along the longitudinal axis 100 of the sabot 4 a substantially constant inner diameter, which corresponds to the maximum outer diameter of the conical body 3 of the projectile body, so that the projectile body 2 is not held by the front guide cage 7, but only by the support wall 8.
Zur Herstellung des Führungskäfigs 7 wird vorzugsweise zunächst ein zylinderförmiges Rohrprofilteil mit der zentralen Ausnehmung 17 und den kammerförmigen Hohlräumen 18 durch Strangpressen hergestellt. Dieses Rohrprofilteil (Fig.5) wird dann nachbearbeitet und in zwei sich in Richtung der Längsachse 100 erstreckende Segmente 9, 10 geteilt (segmentiert), wobei die Lage der Trennlinie in Fig.5 durch das Bezugszeichen 101 angedeutet ist. Sofern erforderlich, können anschließend auch die beiden Segmente 9, 10 noch einmal nachbearbeitet werden.To produce the guide cage 7, a cylindrical tube profile part with the central recess 17 and the chamber-shaped cavities 18 is preferably first produced by extrusion molding. This tubular profile part (FIG. 5) is then reworked and divided (segmented) into two segments 9, 10 extending in the direction of the longitudinal axis 100, the position of the dividing line being indicated by reference numeral 101 in FIG. If necessary, then also the two segments 9, 10 can be reworked again.
Selbstverständlich kann der Führungskäfig 7 beispielsweise auch durch Drehen und Drahterodieren hergestellt werden, was in der Regel aber zu einer kostenaufwendigeren Herstellung führt als die Verwendung von Strangpreßprofilen.Of course, the guide cage 7 can be produced, for example, by turning and wire EDM, which, however, usually leads to a more expensive production than the use of extruded profiles.
Die Fig.6-12 geben ein zweites Ausführungsbeispiel eines erfindungsgemäßen Treibkäfiggeschosses 1 ' wieder. Dabei weist die zentrale Ausnehmung 17' entlang der Längsachse 100 des Treibkäfigs 4' zur Hindurchführung des Geschosskörpers 2' einen sich zur Vorderseite des Führungskäfigs 7' verjüngenden Verlauf auf (Fig.7), derart, dass der Innendurchmesser der zentralen Ausnehmung 17' im heckseitigen Bereich des Führungskäfigs T dem maximalen Außendurchmesser des Geschosskörpers 2' (und damit des Kegelleitwerkes) entspricht und dass der Führungskäfig T den Geschosskörper 2' vorderseitig formschlüssig umschließt, so dass eine separate Stützwand in diesem Fall entfällt.FIGS. 6-12 show a second embodiment of a sabot projectile 1 'according to the invention. In this case, the central recess 17 ' along the longitudinal axis 100 of the sabot 4 ' for passing the projectile body 2 'to a Front side of the guide cage 7 'tapered course on (Fig.7), such that the inner diameter of the central recess 17' in the rear side area of the guide cage T corresponds to the maximum outer diameter of the projectile body 2 '(and thus of the cone tail unit) and that the guide cage T the Projectile body 2 'the front side positively surrounds, so that a separate support wall is omitted in this case.
Auch bei diesem Ausführungsbeispiel wird zur Herstellung des Führungskäfigs T vorzugsweise ein als Hohlprofil ausgebildetes Strangpreßprofil (Fig.12) verwendet. Dieses kann anschließend entsprechend dem vorgegebenen Verlauf der zentralen Ausnehmung 17' ausgedreht und dann in axialer Richtung segmentiert werden.Also in this embodiment, preferably used as a hollow profile extrusion profile (Fig.12) is used to produce the guide cage T. This can then according to the predetermined course of the central recess 17 ' turned out and then be segmented in the axial direction.
Zur vorderseitigen Abstützung des Treibkäfigs 4' an der Innenwand eines entsprechenden Waffenrohres besitzt der Führungskäfig 7' an seinem vorderen Endbereich einen umlaufenden, radial nach außen gerichteten Führungsvorsprung 20. Außerdem umfasst der Führungskäfig 7' vorderseitig einen axialen Vorsprung 21 (Fig.1 1), der von einem ringförmigen Körper aus einem elastischen Material (vorzugsweise aus Gummi) 22 umschlossen ist, welcher in eine Nut 23 des axialen Vorsprunges 21 und in eine Nut 24 des Geschosskörpers 2' eingreift und somit die Segmente 9', 10' des Führungskäfigs T vorderseitig zusammenhält.For the front-side support of the launcher 4 'on the inner wall of a corresponding barrel of the guide cage 7 has' at its front end region a circumferential, radially outwardly directed guide projection 20 also includes the guide cage 7' on the front side an axial projection 21 (Fig.1 1), which is enclosed by an annular body of an elastic material (preferably rubber) 22 which engages in a groove 23 of the axial projection 21 and in a groove 24 of the projectile body 2 ' and thus the segments 9', 10 'of the guide cage T on the front side holds together.
Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So kann beispielsweise im Falle des ersten Ausführungsbeispieles auch die Stützwand vorderseitig einen axialen Vorsprung aufweisen, der von einem ringförmigen Gummikörper umschlossen wird, welcher in eine Nut des axialen Vorsprunges und in eine Nut des Geschosskörpers eingreift.Of course, the invention is not limited to the embodiment described above. Thus, for example, in the case of the first embodiment, the support wall front side having an axial projection which is enclosed by an annular rubber body which engages in a groove of the axial projection and in a groove of the projectile body.
Außerdem müssen die benachbarten Segmente der Funktionsteile des Treibkäfigs (Treibelement, Führungskäfig, Stützwand) nicht zwingend mittels Klebeverbindungen miteinander verbunden sein, sondern es können auch andere Fügeverfahren (beispielsweise zur Herstellung von Löt- oder Schweißverbindungen) eingesetzt werden, sofern sichergestellt ist, dass diese Verbindungen beim Abschuss des jeweiligen Treibkäfiggeschosses durch die auf die Funktionsteile wirkenden Kräfte gelöst werden.In addition, the adjacent segments of the functional parts of the sabot (drive element, guide cage, support wall) need not necessarily be interconnected by means of adhesive joints, but it can also be used other joining methods (for example, for the production of solder or welded joints), provided that it is ensured that these compounds be solved by firing the respective sabot projectile through the forces acting on the functional parts.
Ferner können auch die Zwischenwände 105, welche bei den vorstehend beschriebenen Ausführungsbeispielen die Querrippen 104 miteinander verbinden, entfallen. Ein entsprechendes Ausführungsbeispiel ist in den Fig.13 und 14 dargestellt.Furthermore, the intermediate walls 105, which in the above-described Embodiments connect the transverse ribs 104 together, omitted. A corresponding embodiment is shown in Figs.13 and 14.
Dabei sind der Geschosskörper mit dem Bezugszeichen 2", der Führungskäfig mit dem Bezugszeichen 7" und die Stützwand mit dem Bezugszeichen 8 versehen. Wie insbesondere Fig.14 zu entnehmen ist, sind die Querrippen 104 wiederum mit der Innenwand 103 des Führungskäfigs 7" einstückig verbunden und führen zu seiner Versteifung. In this case, the projectile body with the reference numeral 2 ", the guide cage with the reference numeral 7" and the support wall with the reference numeral 8 are provided. As can be seen in particular from Fig. 14, the transverse ribs 104 are in turn integrally connected to the inner wall 103 of the guide cage 7 "and lead to its stiffening.
