Description

Die Erfindung betrifft ein drallstabilisiertes Trägerge­schoß der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to a spin-stabilized carrier projectile of the type specified in the preamble of claim 1.

Derartige Geschosse sind beispielsweise aus Flume: "Artilleriemunition: Bessere Wirkung im Ziel" Wehrtechnik 1985, Band 10, Seiten 112 bis 120 bekannt. Dabei wird das Trägergeschoß z. B. mit Hilfe eines Geschützes verschossen. Das Trägergeschoß enthält zwei oder mehrere zielerkennende Submunitionskörper, die zu einem vorgegebenen Zeitpunkt aus dem Geschoß ausgestoßen werden. Nach diesem Ausstoß­vorgang erfolgt zunächst ein Drallabbau sowie eine Abbrem­sung der Submunitionskörper. Üblicherweise wird die Ab­bremsung der Geschwindigkeit mit Hilfe eines Fallschirmes vorgenommen und der Drall mit Hilfe sogenannter Drall­flügel abgebaut. Sobald die Geschwindigkeit und der Drall der Submunitionskörper auf vorgegebene Werte reduziert ist, werden die Drallbremse und der zum Geschwindigkeits­abbau benötigte Fallschirm abgesprengt, und es öffnet sich ein weiterer Fallschirm, an dem der Submunitionskörper zur Erde gleitet und eine rotierende Bewegung zwecks Abscannen des Zielgebietes macht. Bei den bekannten drallstabilisier­ten Trägergeschossen haben sich immer wieder Störungen im Funktionsablauf ergeben, die nach dem Ausstoß der Submuni­tionsgeschosse durch den nachfolgenden Geschoßboden des Trägergeschosses verursacht werden.Such projectiles are known, for example, from Flume: "Artillery ammunition: better effect in the target" Wehrtechnik 1985, Volume 10, pages 112 to 120. The carrier floor is z. B. shot with the help of a gun. The carrier projectile contains two or more target-detecting submunitions which are ejected from the projectile at a predetermined time. After this ejection process, the swirl is first reduced and the submunitions decelerated. The speed is usually braked with the help of a parachute and the swirl is reduced with the help of so-called swirl wings. As soon as the speed and swirl of the submunitions are reduced to predetermined values, the swirl brakes and the parachute required for speed reduction are blown off, and another parachute opens, on which the submunitions glides to the ground and makes a rotating movement to scan the target area. In the known spin-stabilized carrier storeys there have repeatedly been malfunctions in the functional sequence which are caused by the subsequent floor of the support storey after the submunition storeys have been ejected.

Der Geschoßboden schlägt nämlich häufig nach dem Aussto­ßen mit dem Heckteil des Submunitionskörpers zusammen und beschädigt dieses bzw. führt zu dessen Instabilität.The floor often hits after the ejection with the rear part of the submunition body and damages it or leads to its instability.

Es ist zwar von der Anmelderin selbst vorgeschlagen wor­den, bei einem drallstabilisierten Nutzlastgeschoß mit Tochtergeschossen eine Störung des Geschoßbodens da­durch zu vermeiden, daß letzterer durch einen Stoß­eingeleitet durch das sich öffnende Bremsankerleitwerk - zurückgeschlagen wird. Eine derartige Anordnung ist jedoch relativ aufwendig und nur in speziellen Fällen anwendbar.It has indeed been proposed by the applicant itself to avoid a malfunction of the floor of the floor in the case of a spin-stabilized payload floor with daughter floors by the latter being kicked back by a shock initiated by the opening brake armature. However, such an arrangement is relatively complex and can only be used in special cases.

Der Erfindung liegt daher die Aufgabe zugrunde, ein drallstabilisiertes Trägergeschoß der eingangs erwähnten Art so weiterzuentwickeln, daß der den Submunitionsge­schossen nach dem Ausstoßen aus dem Trägergeschoß fol­gende Geschoßboden keine Störung der Tochtergeschosse verursacht, ohne daß es hierzu eines Impulses durch ein sich öffnendes Bremsankerleitwerk des Tochtergeschosses bedarf.The invention is therefore based on the object of further developing a swirl-stabilized carrier storey of the type mentioned at the outset such that the floor of the floor following the submunition storeys after ejection from the support storey does not cause any disruption to the daughter storeys without an impulse from an opening brake armature of the subsidiary storey being required for this .

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Die weiteren Unteransprüche offenbaren besonders vor­teilhafte Ausgestaltungen der Erfindung.The further subclaims disclose particularly advantageous embodiments of the invention.

In folgenden werden weitere Einzelheiten und Vorteile der Erfindung anhand eines Ausführungsbeispieles und mit Hilfe von Figuren näher erläutert.In the following further details and advantages of the invention are explained in more detail using an exemplary embodiment and with the aid of figures.

In Fig. 1 ist mit 1 ein drallstabilisiertes Trägerge­schoß bezeichnet, daß beispielsweise mittels eines nicht dargestellten Geschützes verschossen wurde. Dieses Ge­schoß 1 enthält in dem dargestellten Ausführungsbeispiel zwei zielerkennende Submunitionskörper, die zu einem vorge­gebenen Zeitpunkt aus dem Geschoß 1 ausgestoßen werden. Nach diesem Ausstoßvorgang fliegen zunächst die Hülle 10, die Submunitionskörper 20 und 30 sowie der Boden 40 des Geschosses 1 hinereinander. Durch das Entfalten von nicht dargestellten Bremselementen verringern die Submunitions­körper 20 und 30 ihre Geschwindigkeit auf vorgegebene Werte. Da der Geschoßoden 40 mit konstanter Geschwindig­keit weiterfliegt, kommt es häufig zu einem Zusammenstoß zwischen Geschoßboden 40 und Submunitionskörper 30 und damit zu einer Instabilität des Flugverhaltens dieser Ge­schosse.In Fig. 1, 1 denotes a spin-stabilized carrier projectile, which was fired for example by means of a gun, not shown. In the exemplary embodiment shown, this projectile 1 contains two target-recognizing submunitions which are ejected from the projectile 1 at a predetermined time. After this ejection process, first the casing 10, the submunitions 20 and 30 and the floor 40 of the projectile 1 fly towards one another. By deploying brake elements, not shown, the submunitions 20 and 30 reduce their speed to predetermined values. Since the projectile floor 40 continues to fly at a constant speed, there is often a collision between the projectile floor 40 and the submunition body 30 and thus an instability in the flight behavior of these projectiles.

Erfindungsgemäß wird nun vorgeschlagen, den Geschoßboden 40 ebenfalls mit einem Bremselement 43 zu versehen.According to the invention, it is now proposed to also provide the floor 40 with a braking element 43.

In Fig. 2a ist die Seitenansicht eines entsprechenden Geschoßbodens im Querschnitt dargestellt. Dabei bedeuten 41 das in der Regel aus Metall bestehende Bodenstück, 42 ein in dem Bodenstück angeordneter Hohlraum und 43 das Bremselement, das bis zum Ausstoßen der Submuni­tionskörper 20 und 30 zusammengefaltet in dem Hohlraum 42 angeordnet ist. Das Bremselement, welches im wesent­lichen aus einer Gewebescheibe z. B. aus Polyamid oder aus einer Kunststoffolie entsprechender Reißfestigkeit besteht, ist mit Hilfe von Schrauben 44 an das Boden­stückt 41 angeschraubt.In Fig. 2a, the side view of a corresponding floor is shown in cross section. In this case, 41 means the base piece, which is generally made of metal, 42 a cavity arranged in the base piece and 43 the braking element, which is arranged folded up in the cavity 42 until the submunitions 20 and 30 are ejected. The braking element, which consists essentially of a fabric disc z. B. consists of polyamide or a plastic film corresponding tensile strength, is screwed to the bottom piece 41 with screws 44.

In Fig. 2b ist das Bremselement in seinem entfalteten Zustand wiedergegeben. Der Entfaltvorgang läuft dabei wie folgt ab: Nach dem Ausstoßvorgang fliegen die Submunitionskörper 20 und 30 und der Geschoßboden 40 ohne mechanische Verbindung hintereinander her. Durch den Geschoßdrall wird nun die Gewebebremsscheibe 43 nach außen gezogen und verzögert so die Ausströmfläche des Geschoßbodens 40. Infolgedessen bleibt der Geschoßboden sehr schnell hinter dem Submunitionskörper 20 und 30 zurück, so daß eine Beeinflussung der Submunitions­körper durch den Geschoßboden nicht mehr erfolgen kann.2b shows the braking element in its unfolded state. The deployment process proceeds as follows: After the ejection process, the submunitions 20 and 30 and the floor 40 fly one behind the other without a mechanical connection. Due to the projectile swirl, the fabric brake disc 43 is now pulled outward and thus delays the outflow surface of the projectile floor 40. As a result, the projectile floor remains very quickly behind the submunitions 20 and 30, so that the submunition bodies can no longer be influenced by the projectile floor.

In Fig. 3 ist eine Draufsicht auf eine erste erfindungs­gemäße Bremsschiebe nach Fig. 2b von Heck aus gesehen wiedergegeben. Die Bremsscheibe ist wiederum mit 43 und die Befestigungsschrauben sind mit 44 bezeichnet. Vorzugsweise drücken die Befestigungsschrauben 44 nicht direkt die Bremsscheibe 43 gegen das Bodenstück 41 (Fig. 2), sondern es wird eine Scheibe 45 (z. B. aus Metall) gegen das Bodenstück 41 gepreßt.FIG. 3 shows a top view of a first brake slide according to the invention according to FIG. 2b seen from the rear. The brake disc is again 43 and the fastening screws are designated 44. The fastening screws 44 preferably do not directly press the brake disk 43 against the base piece 41 (FIG. 2), but instead a disk 45 (for example made of metal) is pressed against the base piece 41.

In Fig. 4 ist eine zweite erfindungsgemäße Bremsscheibe 43ʹ dargestellt. Mit 432 ist ein Saumband bezeichnet, welches die Aufgabe hat, zu verhindern, daß die Bremsscheibe bei den hohen Rotationen des Geschoßbodens 40 in ihrem Randbereich 431 ausreißt.4, a second brake disc 43ʹ according to the invention is shown. 432 denotes a seam band, which has the task of preventing the brake disc from tearing in its edge region 431 during the high rotations of the floor 40.

Eine weitere Stabilität der Gewebebremsscheibe 43ʹ wird durch zusätzliche Gurtbänder 434, die vorzugsweise kreuz­förmig angeordnet sind, erreicht. Als Material für die Gurtbänder wie für das Saumband hat sich besonders gut Polyamid erwiesen.A further stability of the fabric brake disc 43ʹ is achieved by additional belt straps 434, which are preferably arranged in a cross shape. Polyamide has proven to be a particularly good material for both the webbing and the hem band.

In diesem Zusammenhang sei darauf hingewiesen, daß die Gewebebremsscheibe nicht unbedingt, wie in den Fig. 3 und 4 dargestellt, kreisförmig ausgebildet sein muß. Vielmehr kann sie beispielsweise auch sechs- oder achteckig ausgebildet sein.In this context, it should be noted that the fabric brake disc does not necessarily have to be circular, as shown in FIGS. 3 and 4. Rather, it can also be hexagonal or octagonal, for example.
