Description

Die Erfindung betrifft ein Geschoß mit einem an seinem heckseitigen Ende zur Geschwindigkeitsreduzierung ange­ordneten, beim Flug des Geschosses entfaltbaren, aus einem Gewebe oder einer Kunststoffolie bestehenden Bremselement.The invention relates to a projectile with a brake element arranged at its rear end for speed reduction, which can be deployed during the flight of the projectile and which consists of a fabric or a plastic film.

Derartige Geschosse sind beispielsweise aus der DE-PS 31 27 071 bekannt. Bei dem darin beschriebenen Bremsele­ment, welches sowohl eine Geschwindigkeitsreduzierung als auch eine Stabilität des Geschosses bewirken soll, handelt es sich um entfaltbare Segelflächen, die zwi­schen aufblasbaren Schläuchen angeordnet sind. Die schlauchförmigen Arme werden während des Fluges von einem Gasgenerator aufgeblasen und sind derart angeord­nete, daß die Arme durch das Aufblasen entgegen der Flugrichtung geschwenkt werden können. Dadurch wird der Aufprall des Geschosses am Boden zusätzlich gedämpft, was insbesondere für abwerfbare Minen erforderlich ist.Such projectiles are known for example from DE-PS 31 27 071. The braking element described therein, which is intended to reduce both the speed and the stability of the projectile, is a deployable sail surface which is arranged between inflatable tubes. The tubular arms are inflated by a gas generator during flight and are arranged such that the arms can be pivoted against the direction of flight by the inflation. This additionally dampens the impact of the projectile on the ground, which is particularly necessary for detachable mines.

Die bekannten Bremselemente haben allerdings den Nach­teil, daß sie relativ aufwendig sind, da ein eigener Gasgenerator vorhanden sein muß. Außerdem ist die Steifigkeit der schlauchförmigen Arme, wie sie bei drallstabilisierten Geschossen erforderlich wäre, nicht gegeben.The known brake elements have the disadvantage, however, that they are relatively complex since their own gas generator must be present. In addition, the stiffness of the tubular arms, as would be required with spin-stabilized projectiles, is not provided.

Schließlich nimmt das bekannte Bremselement im zusammen­gefalteten Zustand relativ viel Platz ein, der insbeson­dere auch für die schlauchförmigen Arme benötigt wird.Finally, the known brake element takes up a relatively large amount of space in the folded state, which is also required in particular for the tubular arms.

Der vorliegenden Erfindung liegt daher die Aufgabe zu­grunde, ein Bremselement der eingangs erwähnten Art so weiterzuentwickeln, daß es möglichst wenig Platz in dem Geschoß beansprucht, einfach und stabil aufgebaut ist und bei drallstabilisierten Geschossen sowohl eine Ge­schwindigkeits- als auch eine Drallreduzierung bewirkt.The present invention is therefore based on the object of further developing a braking element of the type mentioned in such a way that it takes up as little space as possible in the projectile, is simple and stable, and both reduces speed and swirl in the case of swirl-stabilized projectiles.

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 Unteransprüche geben besonders vorteilhafte Ausge­staltungen der Erfindung wieder.The subclaims represent particularly advantageous embodiments of the invention.

Ein wesentlicher Gedanke der Erfindung besteht also darin, zur Geschwindigkeits- und Drallreduzierung eine Gewebe­bremsscheibe zu verwenden, an deren Rand, beispielsweise mittels eines Saumbandes, zusätzliche Massen angeordnet sind. Durch diesen Aufbau wird erreicht, daß bei Rotation des Geschosses die größeren Massen, d.h. die Randbe­reiche der Gewebebremsscheiben, zuerst nach außen ge­schleudert werden, so daß sich die Bremsscheibe allein durch die Rotation sehr schnell entfaltet.An essential idea of the invention is therefore to use a fabric brake disc to reduce the speed and twist, on the edge of which additional masses are arranged, for example by means of a hem band. This construction ensures that the larger masses, i.e. the edge areas of the fabric brake disks are first thrown outwards, so that the brake disk unfolds very quickly solely due to the rotation.

Dadurch, daß Stützarme sowie ein separater Gasgenerator entfallen, nimmt die Bremsscheibe im zusammengefalteten Zustand nur wenig Raum in dem Geschoß ein.Because support arms and a separate gas generator are not required, the brake disc takes up little space on the floor when folded.

Nähere Einzelheiten und weitere Vorteile werden im fol­genden anhand von Ausführungsbeispielen und mit Hilfe von Zeichnungen näher erläutert.Further details and further advantages are explained in more detail below on the basis of exemplary embodiments and with the aid of drawings.

Es zeigen:

  • Fig. 2 die Seitenansicht eines Submunitionskörpers gem. Fig. 1 mit erfindungsgemäßem Bremselement;

Show it:
  • Figure 1 shows the timing of the ejection process of submunitions, which are provided with braking elements according to the invention.
  • Fig. 2 shows the side view of a submunition acc. 1 with the braking element according to the invention;
  • FIG. 3 shows the top view of an inventive braking element according to FIG. 2; and
  • Fig. 4 is a plan view of a second embodiment of a braking element according to the invention.

In Fig. 1 ist mit 1 ein Geschoß bezeichnet, das mittels eines nicht dargestellten Geschützes verschossen wurde. Dieses Geschoß 1 enthält zwei intelligente Submunitions­körper, die zu einem vorgegebenen Zeitpunkt aus dem Ge­schoß 1 ausgestoßen werden. Nach diesem Ausstoßvorgang fliegen zunächst die Hülle 100, die Submunitionskörper 200 und 300 sowie der Boden 400 des Geschosses 1 hinter­einander. Durch das Entfalten der Bremselemente (in Fig. 1 ist aus Übersichtlichkeitsgründen nur der Sub­munitionskörper 300 mit Bremselement 30 dargestellt) verringern die Submunitionskörper ihre Geschwindigkeit und bewegen sich auf einer anderen Flugbahn als die weiterfliegende Geschoßhülle 100.In Fig. 1, 1 denotes a projectile which was fired by means of a gun, not shown. This floor 1 contains two intelligent submunitions that are ejected from floor 1 at a predetermined time. After this ejection process, the casing 100, the submunitions 200 and 300 and the floor 400 of the projectile 1 fly one behind the other. By unfolding the brake elements (only the submunition body 300 with the brake element 30 is shown in FIG. 1 for the sake of clarity), the submunition bodies reduce their speed and move on a different trajectory than the projectile shell 100 that flies further.

Das Bremselement 30 bewirkt sowohl eine Geschwindig­keitsverminderung der Submunitionskörper als auch eine Drallreduzierung. Sobald beide Größen auf einen vorge­gebenen Wert abgesunken sind, wird das Bremselement 30 von den Submunitionskörper abgestoßen (nicht dargestellt).The braking element 30 brings about both a reduction in the speed of the submunitions and a swirl reduction. As soon as both variables have dropped to a predetermined value, the braking element 30 is repelled by the submunition body (not shown).

Es kann dann beispielsweise durch Entfalten eines Fall­schirmes ein weiteres Abbremsen der Submunitionskörper sowie durch die rotierende Bewegung dieser Körper ein Abscannen des Zielgebietes erfolgen (vgl. hierzu im einzelnen Flume, "Artilleriemunition: Bessere Wirkung im Ziel"; Wehrtechnik 1985, Heft 10, S 112 ff).The submunitions can then be braked further, for example, by unfolding a parachute, and the target area can be scanned by the rotating movement of these bodies (cf. individual flume, "Artillery ammunition: better effect at the target"; Wehrtechnik 1985, Issue 10, p. 112) ff).

Fig. 2 zeigt eine Seitenansicht des Submunitionskörpers 300 beim Flug mit einem Schnitt im Bereich des Brems­elementes 30. Außer dem Bremselement 30 enthält der Submunitionskörper 300 den eigentlichen Wirkkörper 31, der beispielsweise eine Hohlladung enthält, das Gehäuse 32, welches die Signalverarbeitung und eine nicht dar­gestellte ausschwenkbare Antenne enthalten kann und einen abtrennbaren Stützaufbau 33, an dem die Brems­scheibe 30, beispielsweise mittels Schrauben 330, befestigt ist. Der ringförmige Vorsprung 331 umschließt den Verpackungsraum für das Bremselement 30. Wie aus Fig. 2 ersichtlich ist, bewirken die Luftkräfte, daß das Bremselement 30 eine kegelförmige Gestalt erhält. Durch entsprechende Massen am Rand der Bremsscheibe bzw. durch die Größe der Scheibe ist sicherzustellen, daß die Luftkräfte die Bremsscheibe nicht zusammendrücken.FIG. 2 shows a side view of the submunition body 300 when flying with a cut in the area of the braking element 30. In addition to the braking element 30, the submunition body 300 contains the actual active body 31, which contains, for example, a hollow charge, the housing 32, which processes the signal and one that is not shown can contain swing-out antenna and a detachable support structure 33 to which the brake disc 30 is fastened, for example by means of screws 330. The annular projection 331 encloses the packaging space for the brake element 30. As can be seen from FIG. 2, the air forces cause the brake element 30 to have a conical shape. Appropriate masses on the edge of the brake disc or the size of the disc ensure that the air forces do not compress the brake disc.

In Fig. 3 ist eine Draufsicht auf die erfindungsgemäße Bremsscheibe nach Fig. 2 vom Heck aus gesehen, wieder­gegeben. Mit 36 ist ein Saumband bezeichnet, welches sowohl die Aufgabe hat zu verhindern, daß die Brems­scheibe bei den hohen Rotationen des Geschosses 300 in ihrem Randbereich 35 ausreißt. Noch wesentlicher ist allerdings die Aufgabe des Saumbandes 36, dafür zu sorgen, daß in dem Randbereich 35 eine höhere Mas­senverteilung vorherrscht als in dem restlichen Bereich der Gewebebremsscheibe.FIG. 3 shows a top view of the brake disc according to the invention as shown in FIG. 2 viewed from the rear. 36 is a hem band, which both has the task of preventing the brake disc from tearing in its edge region 35 during the high rotations of the projectile 300. Even more important is the task of the hem band 36 to ensure that a higher mass distribution prevails in the edge region 35 than in the remaining region of the fabric brake disc.

Eine weitere Stabilität der Gewebebremsscheibe 30 wird durch zusätzliche Gurtbänder 37 erreicht, die vorzugsweise kreuzförmig angeordnet sind. Dadurch steigt die Festigkeit des gesamten Bremselementes 30 erheblich. Außerdem können an den Enden der Gurtbänder die zusätzlichen Massen ange­bracht werden, damit ein schnelles Öffnen der Bremsscheibe sichergestellt ist.A further stability of the fabric brake disk 30 is achieved by additional belt straps 37, which are preferably arranged in a cross shape. As a result, the strength of the entire brake element 30 increases considerably. In addition, the additional masses can be attached to the ends of the belt straps so that the brake disc can be opened quickly.

Als Material für die Gewebebremsscheibe aber auch für die Gurtbänder und das Saumband hat sich besonders gut Polyamid oder eine Kunststoffolie ausreichender Festigkeit erwiesen.Polyamide or a plastic film of sufficient strength has proven to be a particularly good material for the fabric brake disc but also for the belt straps and the hem band.

Um eine stärkere Drallreduzierung des Geschosses 300 zu erreichen, hat es sich als vorteilhaft erwiesen, die Gurt­bänder mit Taschen zu versehen. Dieses ist in Fig. 4 dar­gestellt. Dabei müssen die Taschen 38 so angeordnet werden, daß sie sich bei Rotation des Geschosses öffnen. Die Dreh­richtung ist in Fig. 4 mit einem Pfeil angedeutet.In order to achieve a greater twist reduction of the projectile 300, it has proven to be advantageous to provide the belt straps with pockets. This is shown in Fig. 4. The pockets 38 must be arranged so that they open when the projectile rotates. The direction of rotation is indicated in Fig. 4 with an arrow.

Die Gurtbandtaschen 38 können entweder auf den Gurtbändern 37 aufgebracht (z. B. aufgenäht) werden oder sie werden durch einen Teil der Gurtbänder (37) selbst gebildet, indem die Gurtbänder entsprechend auf der Gewebebremsscheibe befestigt (z. B. genäht) werden.The belt webbing pockets 38 can either be applied (e.g. sewn on) to the belt webbings 37 or they are formed by part of the belt webbings (37) themselves, in that the belt webbings are appropriately attached (e.g. sewn) to the fabric brake disc.
