Abstract

A carrier projectile 10 comprises a bottom part 11 and an ogival head part 12 with an ejector plate 12b, and a thin casing 13 which connects the head and bottom parts and which encloses an essentially hollow-cylindrical space for receiving payloads 15. For a more reliable ejection of the payloads 15 by means of an ejector charge 17 arranged in the head part, the head part is made explosion-proof, so that the ejection of the payloads 15 takes place essentially by an axial advance of the pressurised ejector plate 12b, without any undue mechanical load on the thin casing 13. <IMAGE>

Description

Die Erfindung betrifft ein Nutzlastgeschoß nach dem Ober­begriff des Patentanspruchs 1.The invention relates to a payload projectile according to the preamble of patent claim 1.

Die Anmelderin hat bereits ein aus großkalibrigen Rohr­waffen abzuschießendes Nutzlastgeschoß vorgeschlagen, das abweichend von bisher üblichen Geschossen über eine extrem dünne Hülle verfügt. Dünn-bedeutet in diesem Zusammenhang, daß das Verhältnis von Dicke der Hüllenwandung zu Geschoß­kaliber höchstens etwa 0,05 beträgt. Derartig dünne Hüllen bieten den Vorteil, daß für Nutzlasten ein erheblich grö­ßerer Innenraum zur Verfügung steht. Andererseits ist aber die dünne Hülle erheblichen mechanischen Beanspruchungen beim Abschuß des drallstabilisierten Geschosses ausgesetzt, die bisher eine Anwendung derartig dünner Hüllen immer in Frage gestellt haben. Die Nutzlasten sollen über dem Ziel­gebiet auf an sich bekannt Weise durch eine Ausstoßladung ausgestoßen werden. Da jedoch die dünne Hülle nicht druckfest genug ist, kann sie nicht ohne weiteres mit einem für das Ausstoßen der Nutzlasten erforderlichen Innendruck beaufschlagt werden.The applicant has already proposed a payload projectile to be fired from large-caliber barrel weapons, which, in contrast to the conventional projectiles, has an extremely thin shell. In this context, thin means that the ratio of the thickness of the casing wall to the projectile caliber is at most about 0.05. Such thin casings offer the advantage that a considerably larger interior space is available for payloads. On the other hand, however, the thin casing is exposed to considerable mechanical stresses when the spin-stabilized projectile is fired, which have so far always questioned the use of such thin casings. The payloads are to be ejected via the ejection charge in a manner known per se over the target area. However, since the thin sheath is not pressure-resistant enough, it cannot readily be subjected to the internal pressure required to eject the payloads.

Der Erfindung liegt die Aufgabe zugrunde, das Nutzlastge­schoß dahingehend auszubilden, daß ein sichere Ausstoßen der Nutzlasten vermittels einer Ausstoßladung möglich ist.The invention has for its object to design the payload storey in such a way that the payloads can be safely ejected by means of an ejection charge.

Ausgehend von einem Nutzlastgeschoß der eingangs näher bezeichneten Art wird diese Aufgabe durch die im kenn­zeichnenden Teil des Patentanspruchs 1 angegebenen Merk­male gelöst.Starting from a payload projectile of the type specified in the introduction, this object is achieved by the features specified in the characterizing part of patent claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen gehen aus den Unteransprüchen hervor.Advantageous refinements and developments emerge from the subclaims.

Die Erfindung wird nachfolgend unter Bezug auf die Zeich­nung näher erläutert. Die einzige Figur zeigt einen Längsschnitt durch ein in Längsachsenrichtung halbiert dargestelltes Nutzlastgeschoß.The invention is explained in more detail below with reference to the drawing. The single figure shows a longitudinal section through a payload projectile shown halved in the longitudinal axis direction.

Das Nutzlastgeschoß 10 umfaßt einen Bodenteil 11 und einen ogivalen Kopfteil 12, die durch eine dünne Hülle 13 miteinander verbunden sind. Die Verbindung zwischen Bodenteil 11 und dünner Hülle 13 erfolgt zweckmäßig durch in Radialrichtung eingebrachte Verschraubungen oder über Scherstifte 14. Die dünne Hülle 13 umschließt einen im wesentlichen hohlzylindrischen Raum zur Auf­nahme lediglich schematisch angedeuteter Nutzlasten 15, die übereinander gestapelt zwischen Bodenteil 11 und Kopfteil 12 innerhalb des Nutzlastgeschosses 10 ange­ordnet sind. Bei diesen Nutzlasten 15 kann es sich beispielsweise um zielerkennende projektilbildende Ladungen handeln, die nach dem Ausstoßen aus dem Nutz­lastgeschoß gebremst herabsinken, ihr Ziel selbst er­kennen und zerstören. Der Kopfteil 12 des Nutzlastge­schosses umfaßt eine ogivale Außenhülle 12a und eine Ausstoßplatte 12b, die die ogivale Außenhülle 12a heckseitig verschließt und innerhalb dieser in Axial­richtung verschiebbar gelagert ist. Die Hülle 12a um­schließt eine von einem beispielsweise im Kopf des Geschosses 10 angeordneten Zünder 16 beaufschlagbare Ausstoßladung 17, die nach Aktivierung durch den Zünder 16 auf pyrotechnischem Weg Gase freisetzt, die in dem von der ogivalen Außenhülle 12a und der Ausstoß­platte 12b begrenzten Raum den Aufbau eines hohen Drucks bewirken. Da die Außenhülle 12a und die Ausstoßplatte 12b durch Wahl geeigneter Materialdicke berstsicher ausgeführt sind, kann sich die aufgrund des Drucks entstehende Kraft nur auf die glatbar gelagerte Aus­stoßplatte 12b auswirken, die demzufolge in Axial­richtung zum Heck des Geschosses 11 hin bewegt wird. Dabei werden die Scherstifte 14 abgeschert, so daß sich das Bodenteil 11 von der dünnen Hülle 13 ablösen kann und die Nutzlasten 15 ausgestoßen werden können. Während dieses Ausstoßvorgangs gleitet die Ausstoß­platte 12b umfangsseitig im Bereich A auf der Innen­wandung der ogivalen Außenhülle 12a entlang. Auf diese Weise wird die zum Abscheren der Scherstifte 14 und Ausstoßen der Nutzlasten 15 erforderliche Kraft aufge­bracht, ohne daß die dünne Hülle 13 mit einem unzuläs­sig hohen Innendruck beaufschlagt wird.The payload floor 10 comprises a base part 11 and an ogival head part 12, which are connected to one another by a thin casing 13. The connection between the base part 11 and the thin shell 13 is expediently carried out by means of screw connections introduced in the radial direction or via shear pins 14. The thin shell 13 encloses an essentially hollow cylindrical space for receiving only schematically indicated payloads 15, which are stacked on top of one another between the base part 11 and the head part 12 within the Payload floor 10 are arranged. These payloads 15 can, for example, be target-recognizing projectile-forming charges which, after being ejected from the payload storey, drop down, recognize and destroy their target themselves. The head part 12 of the payload projectile comprises an ogival outer casing 12a and an ejection plate 12b, which closes the ogival outer casing 12a at the rear and is mounted so that it can be displaced in the axial direction. The casing 12a encloses an ejection charge 17 which can be acted upon by an igniter 16, for example, arranged in the head of the projectile 10 and which, after activation, by the Igniter 16 releases gases in a pyrotechnic way, which cause the build-up of high pressure in the space delimited by the ogival outer shell 12a and the ejection plate 12b. Since the outer casing 12a and the ejection plate 12b are designed to be burst-proof by selecting a suitable material thickness, the force arising due to the pressure can only affect the smoothly mounted ejection plate 12b, which is consequently moved in the axial direction towards the rear of the projectile 11. The shear pins 14 are sheared off, so that the base part 11 can detach from the thin shell 13 and the payloads 15 can be ejected. During this ejection process, the ejection plate 12b slides along the circumference in area A on the inner wall of the ogival outer casing 12a. In this way, the force required to shear the shear pins 14 and to eject the payloads 15 is applied without the thin casing 13 being subjected to an impermissibly high internal pressure.

In weiterer vorteilhafter Ausgestaltung der Erfindung kann zwischen der heckseitig angeordneten Nutzlast und dem Bodenteil 11 noch ein Zwischenboden 18 ange­ordnet sein. Dieser Zwischenboden 18 begrenzt dann einen Raum 18a, in dem eine zusätzliche Treibladung untergebracht ist, die das Abscheren der Scherstifte 14 bewirkt, so daß die Treibladung 17 lediglich für das Ausstoßen der Nutzlast 15 verantwortlich ist. Die im Raum 18a angeordnete zusätzliche Treibladung kann ebenfalls vom Zünder 16 aktiviert werden, wobei erforderlichenfalls durch einen Verzögerungssatz sicherzustellen ist, daß zunächst die Treibladung im Raum 18a und dann die Ausstoßladung 17 gezündet wird.In a further advantageous embodiment of the invention, an intermediate floor 18 can also be arranged between the payload arranged at the rear and the floor part 11. This intermediate floor 18 then delimits a space 18a in which an additional propellant charge is accommodated, which causes the shear pins 14 to shear off, so that the propellant charge 17 is only responsible for ejecting the payload 15. The additional propellant charge arranged in the space 18a can also be activated by the igniter 16, it being necessary, if necessary, to ensure by means of a delay set that the propellant charge in the space 18a and then the exhaust charge 17 is ignited.

Abgesehen vom Abscheren der Scherstifte 14 kann die Treibladung im Raum 18a auch noch dazu beitragen, daß das relativ massiv ausgestaltete Bodenteil 11 hinreichend weit vom Geschoß 11 weggeschleudert wird, so daß die aus­gestoßenen Nutzlasten 15 und die daran ggf. befestigten Fallschirme in ihrer Funktion nicht beeinträchtigt werden.Apart from the shearing off of the shear pins 14, the propellant charge in the space 18a can also contribute to the relatively solidly designed base part 11 being flung sufficiently far away from the projectile 11 so that the ejected payloads 15 and the parachutes possibly attached to them do not impair their function will.

In einem anderen Ausführungsbeispiel der Erfindung ist im Raum 18a eine kräftige Druckfeder 18b angeordnet, die nach Abscheren der Scherstifte 14 vermittels der von der Ausstoßladung 17 auf die Ausstoßplatte 12b und die Nutz­last 15 ausgeübten Kraft eine zusätzliche Kraftwirkung auf das Bodenteil 11 ausübt, um dieses vom Nutzlastge­schoß 10 fortzuschleudern.In another embodiment of the invention, a strong compression spring 18b is arranged in the space 18a, which, after the shear pins 14 have been sheared off by means of the force exerted by the ejection charge 17 on the ejection plate 12b and the payload 15, exerts an additional force effect on the base part 11 in order to prevent the latter from Throwing the payload floor 10 away.
