Description

Die Erfindung betrifft eine Einrichtung zum Ausziehen eines Bremsschirmes nach dem Oberbegriff des Anspruches 1.The invention relates to a device for pulling out a brake screen according to the preamble of claim 1.

In der DE-PS 36 08 107 ist eine derartige Einrichtung beschrieben, Nach dem Ausstoß der Submunition aus einem Trägerprojektil reißt die zwischen den beiden Submunitionen vorgesehene Ausziehleine, mit der der Bremsschirm der vorderen Submunition geöffnet werden soll nahe bei diesem. Die Ausziehleine verbleibt an der hinteren Submunition. Dies kann zu Schwierigkeiten führen, da sich die Ausziehleine dann mit einem Rotationsschirm oder dem Bremsschirm der hinteren Submunition verwickeln kann.Such a device is described in DE-PS 36 08 107. After the submunition has been ejected from a carrier projectile, the pull-out line provided between the two submunitions, with which the brake parachute of the front submunition is intended to be opened, tears near it. The pull line remains on the rear submunition. This can lead to difficulties, since the pull-out line can then become tangled with a rotating parachute or the braking parachute of the rear submunition.

Aufgabe der Erfindung ist es, eine Einrichtung der eingangs genannten Art vorzuschlagen, bei der eine Beeinträchtigung der hinteren Submunition durch die Ausziehleine vermieden ist.The object of the invention is to propose a device of the type mentioned, in which an impairment of the rear submunition by the pull-out line is avoided.

Obige Aufgabe ist gemäß der kennzeichnenden Merkmale des Anspruches 1 gelöst.The above object is achieved according to the characterizing features of claim 1.

Durch die weitere Leine wird, wenn sich die Submunitionen voneinander entfernen, der Schleifknoten der Ausziehleine geöffnet, mit dem diese mit der hinteren Submunition verbunden ist. Die Ausziehleine und auch die weitere Leine verbleiben am dann geöffneten Bremsschirm der vorderen Submunition. Sie können diesen nicht beeinträchtigen. Es ist jedenfalls vermieden, daß die Ausziehleine oder auch die weitere Leine an der hinteren Submunition verbleiben.When the submunitions move away from each other, the additional line opens the grinding knot of the pull-out line, with which it is connected to the rear submunition. The pull-out line and the other line remain on the open brake parachute of the front submunition. You cannot affect it. In any case, it is avoided that the pull-out line or the other line remains on the rear submunition.

Günstig ist auch, daß diese Einrichtung sowohl im Aufbau als auch in der Montage einfach ist.It is also favorable that this device is simple both in terms of its structure and its assembly.

In bevorzugter Ausgestaltung der Erfindung ist die Ausziehleine schlauchartig gestaltet und die weitere Leine verläuft als Innenleine durch die Ausziehleine, wobei die Innenleine im Bereich des Schleifknotens aus der Ausziehleine herausgeführt ist. Die Innenleine ist dadurch einfach durch den Packsack an den Bremsschirm zu führen. Sie kann sich auch nicht mit der Ausziehleine verwickeln.In a preferred embodiment of the invention, the pull-out line is designed like a tube and the further line runs as an inner line through the pull-out line, the inner line being led out of the pull-out line in the region of the grinding knot. The inner line is therefore easy to lead through the stuff sack to the brake parachute. It also cannot get tangled with the pull-out line.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispiels. In der Zeichnung zeigen:

  • Figur 1 drei aufeinanderfolgende Stadien der Trennung eines Submunitionpaars,
  • Figur 2 die Ausziehleine und die weitere Leine im Bereich der vorderen Submunition und
  • Figur 3 die Ausziehleine und die weitere Leine im Bereich der hinteren Submunition.
Further advantageous refinements of the invention result from the following description of an exemplary embodiment. The drawing shows:
  • FIG. 1 shows three successive stages in the separation of a submunition pair,
  • Figure 2, the pull-out line and the other line in the area of the front submunition and
  • Figure 3, the pull-out line and the other line in the area of the rear submunition.

In einem nicht näher dargestellten Trägerprojektil sind eine hintere Submunition(1) und eine vordere Submunition(2) dicht aneinanderliegend untergebracht. Ein Fallschirmdeckel(3) der hinteren Submunition(1) deckt dabei den in einem Packsack(4) verstauten Bremsschirm(5) der vorderen Submunition(2) ab. Im Fallschirmdeckel(3) liegen dabei auch eine Ausziehleine(6), die einerseits am Packsack(4) befestigt ist und andererseits mit dem Fallschirmdeckel(3) der hinteren Submunition(1) verbunden ist. Die Innenleine(7) is an der Kappe(8) des Bremsschirms(5) befestigt.In a carrier projectile, not shown, a rear submunition (1) and a front submunition (2) are housed close together. A parachute cover (3) of the rear submunition (1) covers the brake parachute (5) of the front submunition (2) stowed in a stuff sack (4). In the parachute cover (3) there is also a pull-out line (6) which is attached to the pack sack (4) on the one hand and is connected to the parachute cover (3) of the rear submunition (1) on the other hand. The inner line (7) is attached to the cap (8) of the brake screen (5).

Die Submunitionen(1,2) werden aus dem Trägerprojektil ausgestoßen. Ihre Flugrichtung ist in Figur 1 mit F bezeichnet. Beim Ausstoßen öffnet sich ein Bremsschirm(9) der hinteren Submunition(1). Dadurch wird die hintere Submunition(1) gegenüber der vorderen Submunition(2) abgebremst, so daß sich die Ausziehleine(6) spannt. Dieser Zustand ist in Figur 1a gezeigt, wobei die Figuren 2 und 3 vergrößerte Teildarstellungen sind.The submunitions (1,2) are ejected from the carrier projectile. Their direction of flight is designated by F in FIG. When ejecting, a brake screen (9) of the rear submunition (1) opens. As a result, the rear submunition (1) is braked in relation to the front submunition (2), so that the pull-out line (6) tensions. This state is shown in FIG. 1a, with FIGS. 2 and 3 being enlarged partial representations.

Die Ausziehleine(6) ist schlauchförmig gestaltet. In ihr verläuft die Innenleine(7) (vgl. Figur 2). Sie erstreckt sich durch den Packsack(4) hindurch bis zur Kappe(8). Die Innenleine(7) ist an einer öffnung(10) aus der Ausziehleine(6) herausgeführt. An dem Fallschirmdeckel(3) ist eine Gegenstück(11), das einen Kopf(12) aufweist, angeordnet. Mit diesem Gegenstück(11) ist die Ausziehleine(6) durch einen Schleifknoten(13) verbunden (vgl. Figur 3). Wie Figur 3 zu entnehmen, sind die Ausziehleine(6) und die Innenleine(7) ein einziges Stück. Es wäre jedoch auch möglich, als Ausziehleine(6) und als Innenleine(7) jeweils ein eigenes Stück vorzusehen. Die Innenleine(7) wäre dann an einer geeigneten Stelle mit dem Schleifknoten(13) der Ausziehleine(6) verbunden.The pull-out line (6) is tubular. The inner line (7) runs in it (see FIG. 2). It extends through the stuff sack (4) to the cap (8). The inner line (7) is led out of the pull-out line (6) at an opening (10). A counterpart (11), which has a head (12), is arranged on the parachute cover (3). The pull-out line (6) is connected to this counterpart (11) by a grinding knot (13) (cf. FIG. 3). As can be seen in FIG. 3, the pull-out line (6) and the inner line (7) are a single piece. However, it would also be possible to provide a separate piece for the pull-out line (6) and the inner line (7). The inner line (7) would then be connected to the grinding knot (13) of the pull-out line (6) at a suitable point.

Im Zuge des weiteren Flugs löst sich der über die Ausziehleine(6) und deren Schleifknoten(13) an der hinteren Submunition(1) gehaltene Packsack(4) von der vorderen Submunition(2). Deren mit ihr über eine Verbindungsleine(14) verbundene Bremsschirm(5) beginnt sich zu entalten. Dieser Zustand ist in Figur 1b gezeigt.In the course of the further flight, the pack sack (4) held on the pull-out line (6) and its grinding knot (13) on the rear submunition (1) releases from the front submunition (2). The brake screen (5) connected to it via a connecting line (14) begins to unfold. This state is shown in Figure 1b.

Bei dem weiteren Entfernen der vorderen Submunition(2) von der hinteren Submunition(1) entfaltet sich der Bremsschirm(5). Seine Kappe(8) zieht nun an der Innenleine(7), die dadurch den Schleifknoten(13) aufzieht, so daß sich die Ausziehleine(6) und die Innenleine(7) von dem Gegenstück(11) der hinteren Submunition(1) lösen. Dieser Zustand ist in Figur 1c gezeigt. Die beiden Submunitionen(1,2) sind nun gegeneinander frei. Die Ausziehleine(6) und die Innenleine(7) sind von der hinteren Submunition(1) getrennt. Sie bleiben mit dem Bremsschirm(5) der vorderen Submunition(2) verbunden, ohne diesen zu stören.When the front submunition (2) is further removed from the rear submunition (1), the brake parachute (5) deploys. His cap (8) now pulls on the inner line (7), which thereby tightens the grinding knot (13), so that the pull-out line (6) and the inner line (7) detach from the counterpart (11) of the rear submunition (1) . This state is shown in Figure 1c. The two submunitions (1,2) are now free from each other. The pull-out line (6) and the inner line (7) are separated from the rear submunition (1). They remain connected to the brake screen (5) of the front submunition (2) without disturbing it.
