Die Erfindung betrifft ein Geschoss mit einem ein Kegelleitwerk aufweisenden unterkalibrigen Penetrator und einem im Wesentlichen scheibenförmigen Treibelement, wobei das Kegelleitwerk eine heckseitig offene kegelstumpfförmige Ausnehmung aufweist, insbesondere einen so genannten Fluggeschoss- Befestigungsbolzen.The invention relates to a projectile with a conical structure having a subcaliber penetrator and a substantially disc-shaped driving element, wherein the conical structure has a tail-open frusto-conical recess, in particular a so-called flying projectile fastening bolts.
Ein derartiges Geschoss ist beispielsweise aus der
In der Praxis hat sich gezeigt, dass sich bereits durch die normale Handhabung des Geschosses zwischen Treibelement und Kegelleitwerk ein Spiel ergeben kann, so dass nach Schussabgabe zu Beginn des Gasdruckaufbaus im Waffenrohr Treibladungsgase unter die Aufstandsfläche des Kegelleitwerkes strömen. Dadurch wird einerseits eine optimale Beschleunigung des Penetrators innerhalb des Waffenrohres verhindert und andererseits können Störungen des Penetrators durch das Treibelement nach Verlassen des Waffenrohres erfolgen.In practice, it has been found that even through the normal handling of the projectile between the drive element and the conical structure, a clearance can result, so that after firing at the beginning of the gas pressure build-up in the weapon tube, propellant gases flow under the contact surface of the conical structure. As a result, on the one hand prevents optimal acceleration of the penetrator within the gun barrel and on the other hand, interference of the penetrator can be done by the driving element after leaving the gun barrel.
Der Erfindung liegt die Aufgabe zugrunde, ein Geschoss der eingangs erwähnten Art anzugeben, bei dem sowohl bei normaler Handhabung des Geschosses als auch bei Schussabgabe das Treibelement spielfrei mit dem Penetrator verbunden ist und bei dem sich das Treibelement nach Verlassen des Waffenrohres störungsfrei von dem Penetrator löst.The invention has for its object to provide a projectile of the type mentioned, in which both in normal handling of the projectile as well as firing the drive element is connected without play with the penetrator and in which the drive element after leaving the barrel dissolves smoothly from the penetrator ,

Dabei weist das Schraubelement eine heckseitig offene Bohrung auf, in die beim Abschuss des Geschosses Treibladungsgase gelangen, und wobei das Schraubelement derart ausgelegt ist, dass der in der Bohrung durch die Treibladungsgase entstehende Innendruck zu einem Aufreißen des Schraubelementes und damit zu einer Trennung von Treibelement und Penetrator führt.The invention is based essentially on the idea not to connect the driving element as in comparable known projectiles via a form-fitting or clamping connection with the penetrator, but on a projectile mounting bolt with preferably predetermined breaking point and pressure reducing nozzles, wherein a screw is provided, which by the frusto-conical recess of the conical structure is passed and connects the driving element and the penetrator with each other. In this case, the screw on a rear side open bore, get into the launch of the projectile propellant gases, and wherein the screw is designed such that the resulting in the bore by the propellant gases internal pressure to rupture of the screw and thus to a separation of the driving element and Penetrator leads.
Bei einer ersten Ausführungsform der Erfindung umfasst das Schraubelement ein erstes Teilelement, welches vorderseitig ein Innengewinde aufweist und mit dem Außengewinde eines zweiten Teilelementes axial verschraubt ist, welches seinerseits mit der das Leitwerk vorderseitig begrenzenden Rückwand des Leitwerkes verbunden ist. Dabei kann es sich bei dem zweiten Teilelement um einen mit einem Außengewinde versehenen Leuchtspurnapf handeln.In a first embodiment of the invention, the screw member comprises a first sub-element, which has an internal thread on the front side and is screwed axially to the external thread of a second sub-element, which in turn is connected to the front side delimiting the tail rear wall of the tail. In this case, it may be at the second sub-element is provided with an external thread Leuchtspurnapf.
Vorzugsweise kann das erste Teilelement des Schraubelementes bolzenförmig ausgebildet sein und aus einem Kopfteil und einem Schaftteil bestehen, wobei das Schaftteil durch eine Bohrung des Treibelementes hindurch in die kegelstumpfförmige Ausnehmung hineingeführt und mit dem zweiten Teilelement verschraubt ist und wobei das Kopfteil die Bohrung des Treibelementes heckseitig seitlich überragt und sich an der heckseitigen Oberfläche des Treibelementes abstützt.Preferably, the first part of the screw element can be bolt-shaped and consist of a head part and a shaft part, wherein the shaft part is guided through a bore of the driving element into the frusto-conical recess and bolted to the second sub-element and wherein the head part of the bore of the drive element laterally laterally surmounted and supported on the rear surface of the drive element.
Das erste Teilelement des Schraubelementes kann aber auch mehrteilig ausgebildet sein und ein napfförmiges Befestigungsteil zum Aufschrauben auf den Leuchtspurnapf und einen mit einer Durchgangsbohrung versehenen Schraubbolzen umfassen, welcher einen Bolzenkopf und einen mit einem Außengewinde versehenen Schaft besitzt, wobei der Schaft in einer axial durch das Treibelement hindurchgehenden Gewindebohrung gelagert ist, derart, dass das dem Bolzenkopf abgewandte Ende des Schaftes von der heckseitigen Oberfläche des Treibelementes aus drehbar ist und dass der Bolzenkopf in einer Ausnehmung des napfförmigen Befestigungsteiles drehfest gelagert ist.The first sub-element of the screw but can also be designed in several parts and include a cup-shaped attachment part for screwing on the tracer and a provided with a through hole bolts, which has a bolt head and a shaft provided with an external thread, wherein the shaft in an axial by the drive element through threaded hole is mounted, such that the bolt head facing away from the end of the shaft is rotatable from the rear surface of the drive element and that the bolt head is rotatably mounted in a recess of the cup-shaped attachment member.
Bei einer weiteren Ausführungsform der Erfindung ist das Treibelement mit einem axial in die kegelstumpfförmige Ausnehmung ragenden bolzenförmigen Schraubelement verbunden, welches direkt in ein Innengewinde der Rückwand des Penetrators eingeschraubt ist.In a further embodiment of the invention, the drive element is connected to an axially projecting into the frusto-conical recess bolt-shaped screw, which is screwed directly into an internal thread of the rear wall of the penetrator.
Um eine gute Zentrierung des Kegelleitwerkes in Bezug auf das Treibelement sicherzustellen, hat es sich als vorteilhaft erwiesen, wenn das Treibelement auf ihrer dem Leitwerk des entsprechenden Geschosses zugewandten Seite eine Ausnehmung zur formschlüssigen Aufnahme des heckseitigen Endbereiches des Leitwerkes aufweist.In order to ensure a good centering of the conical structure with respect to the driving element, it has proved to be advantageous if the driving element has on its side facing the tail of the corresponding projectile a recess for positive reception of the rear end portion of the tail.
Das Treibelement kann vorzugsweise aus einem Leichtmetall, beispielsweise einer Aluminium- oder einer Magnesiumlegierung, aber auch aus Stahl bestehen. Sie kann sowohl zur Beschleunigung von unterkalibrigen Gefechtsgeschossen als auch zur Beschleunigung unterkalibriger Ãœbungsgeschossen eingesetzt werden.The drive element may preferably consist of a light metal, for example an aluminum or a magnesium alloy, but also of steel. It can be used both to accelerate sub-caliber battle shells and to accelerate sub-caliber practice bullets.
Die vorgenannte Konstruktion ist nicht nur kostengünstig, sondern besitzt auch eine sehr gute Funktion. Sie ist temperatur- und belastungsstabil und zeichnet sich durch eine einfache Fertigung ohne Montagewerkzeuge aus. Zudem ist der Leitwerksgasinnendruck einstellbar, derart, dass mit dem Durchmesser der Hohlbohrung, dem Verhältnis des Anfangs- Hochvolumens im Bolzen und des abschließenden Volumens im Leitwerksbereich den maximale entstehenden Innen- Gasdruck im Leitwerksende einstellen kann. Gleichzeitig kann über die einströmenden Gase eine eventuell vorhandene Leuchtspur gezündet werden.The aforementioned construction is not only inexpensive, but also has a very good function. It is temperature and load stable and is characterized by a simple production without assembly tools. In addition, the internal combustion gas pressure is adjustable, such that with the diameter of the hollow bore, the ratio of the initial high volume in the bolt and the final volume in the tail area can set the maximum resulting internal gas pressure in the tail end. At the same time a possibly existing trace of light can be ignited via the incoming gases.
