Abstract

In a submunition (1) with a stabilising parachute (4), the latter is to be deployed from its packed position independently of a carrier projectile. The pull-out device is formed by a balloon (3) inflatable by means of a gas generator (11). The stabilising parachute (4) is arranged inside the balloon (3) and in the inflated balloon (3) is pulled out of its packed position in this. The balloon (3) bursts after the inflation and thus releases the stabilising parachute (4) for deployment. <IMAGE>

Description

Die Erfindung betrifft eine Submunition mit einem Stabilisierungsschirm und einer Auszieheinrichtung zum Ausbringen des Stabilisierungsschirmes aus seiner Packstellung in einem Aufnahmeraum der Submunition.The invention relates to a submunition with a stabilizing screen and a pull-out device for deploying the stabilizing screen from its packing position in a receiving space of the submunition.

Der Stabilisierungsschirm dient der Lageorientierung und Abbremsung der Submunition nach deren Ausstoßen aus einem Trägergeschoß.The stabilization screen is used for orientation and braking of the submunition after it has been ejected from a carrier floor.

In der DE-PS 36 08 107 ist eine Submunition beschrieben. Bei dieser ist der Stabilisierungsschirm mittels einer Ausziehleine mit einem auszustoßenden Boden des Trägergeschosses verbunden. Der Boden selbst ist mit einem Bremssegel versehen, das unter der Wirkung des Dralls aufgespannt wird. Das Ausziehen des Stabilisierungsschirmes der Submunition ist somit vom Flug des Bodens abhängig.DE-PS 36 08 107 describes a submunition. In this case, the stabilizing screen is connected to a floor of the supporting floor to be ejected by means of an extension line. The floor itself is provided with a brake sail, which is stretched under the action of the swirl. Extending the stabilization screen of the submunition depends on the flight of the ground.

Aufgabe der Erfindung ist es, eine Submunition der eingangs genannten Art vorzuschlagen, bei der die Funktion der Auszieheinrichtung unabhängig von Teilen eines Trägergeschosses ist, aus dem die Submunition ausgestoßen wird, und unabhängig von dessen Drall ist.The object of the invention is to propose a submunition of the type mentioned in the introduction, in which the function of the extracting device is independent of parts of a carrier projectile from which the submunition is ejected and is independent of its swirl.

Erfindungsgemäß ist obige Aufgabe bei einer Submunition der eingangs genannten Art dadurch gelöst, daß die Auszieheinrichtung von einem mittels eines Gasgenerators aufblasbaren Ballon gebildet ist, der an der Submuniton befestigt und in Packstellung in dem Aufnahmeraum verstaut ist, daß der Stabilisierungsschirm innerhalb des Ballons angeordnet und im aufgeblasenen Ballon in diesem ausgezogen ist und daß der Ballon nach dem Aufblasen platzt.According to the invention, the above object is achieved in the case of submunition of the type mentioned at the outset in that the pull-out device is formed by a balloon which is inflatable by means of a gas generator and which is attached to the submunition fastened and stowed in the receiving space in the packing position, that the stabilizing screen is arranged inside the balloon and extended in the inflated balloon and that the balloon bursts after inflation.

In der Packstellung sind der Ballon und der Stabilisierungsschirm in der Submunition verstaut. Der zusätzliche Platzbedarf des Ballons ist gering.In the pack position, the balloon and the stabilization screen are stowed in the submunition. The additional space requirement of the balloon is minimal.

Nach dem Ausstoßen der Submunition aus einem Trägerprojektil wird zu einem geeigneten Zeitpunkt der Gasgenerator ausgelöst. Dieser bläst den Ballon auf. Dies ist unabhängig von dem Drall des Trägerprojektils bzw. dessen ausgestoßenen Boden. Mit dem Aufweiten des Ballons wird der in ihm liegende Stabilisierungsschirm eusgezogen. Besonders günstig ist, daß der aufgeblasene Ballon selbst zur Stabilisierung der Fluglage der Submunition beiträgt.After the submunition has been ejected from a carrier projectile, the gas generator is triggered at a suitable time. This inflates the balloon. This is independent of the swirl of the carrier projectile or its ejected floor. As the balloon expands, the stabilizing screen in it is pulled out. It is particularly favorable that the inflated balloon itself contributes to stabilizing the flight position of the submunition.

Der Ballon platzt dann, so daß danach der Stabilisierungsschirm angeströmt wird und die Submunition stabilisiert und bremst.The balloon then bursts, so that the stabilization screen is then flowed onto and the submunition stabilizes and brakes.

Insgesamt ist ein sicherer Funktionsablauf gewährleistet.Overall, a safe functional sequence is guaranteed.

Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und der folgenden Beschreibung eines Ausführungsbeispiels. In der Zeichnung zeigen:

  • Figur 1 eine Submunition nach dem Ausstoß aus einem Trägerprojektil,
  • Figur 2 die Submunition mit aufgeblasenem Ballon und ausgezogenem Stabilisierungsschirm und
  • Figur 3 die Submunition mit geplatztem Ballon und aufgespanntem Stabilisierungsschirm.
Advantageous refinements of the invention result from the subclaims and the following description of an exemplary embodiment. The drawing shows:
  • FIG. 1 shows a submunition after being ejected from a carrier projectile,
  • Figure 2 shows the submunition with an inflated balloon and extended stabilization screen and
  • Figure 3 shows the submunition with burst balloon and open stabilization screen.

Eine Submunition(1) weist einen Aufnahmeraum(2) auf. In diesem ist ein Ballon(3) befestigt. Innerhalb des Ballons(3) ist ein Stabilisierungsschirm(4) angeordnet, dessen Halteleinen(5) ebenfalls im Aufnahmeraum(2) befestigt sind.A submunition (1) has a receiving space (2). A balloon (3) is attached in this. A stabilizing screen (4) is arranged inside the balloon (3), the holding lines (5) of which are also fastened in the receiving space (2).

Eine Scheitelstelle(6) des Stabilisierungsschirms(4) ist mit einer Scheitelstelle(7) des Ballons(3) fest verbunden. Am Umfang des Ballons(3) ist eine Sollbruchlinie(8) zwischen einem Ballonoberteil(9) und einem Ballonunterteil(10) ausgebildet. Die Sollbruchlinie(8) liegt so, daß das Ballonoberteil(9) ein Auffalten des Stabilisierungsschirms(4) nicht behindert.A vertex (6) of the stabilizing screen (4) is firmly connected to a vertex (7) of the balloon (3). A predetermined breaking line (8) is formed on the circumference of the balloon (3) between an upper balloon part (9) and a lower balloon part (10). The predetermined breaking line (8) is such that the upper balloon part (9) does not prevent the stabilizing screen (4) from unfolding.

Die Submunition(1) weist einen Gasgenerator(11) auf, mit welchem der Ballon(3) bis zum Zerplatzen aufblasbar ist.The submunition (1) has a gas generator (11) with which the balloon (3) can be inflated until it bursts.

In der Packstellung (vgl. Figur 1) sind der Ballon(3) und der in ihm liegende Stabilisierungsschirm(4) in dem Aufnahmeraum(2) verstaut. Nach dem Ausstoß der Submunition(1) wird nach einer gewissen Zeit ein Impuls an den Gasgenerator(11) gegeben. Dieser bläst den Ballon(3) dann auf. Die Submunition(1) ist dabei einer Anströmung(A) ausgesetzt (vgl. Figur 2). Beim Aufblasen des Ballons(3) wird der Stabilisierungsschirm(4) vom Ballon(3) aus dem Aufnahmeraum(2) mit ausgezogen (vgl. Figur 2). Der aufgeblasene Ballon(3) stabilisiert die Fluglage der Submunition(1) in der Anströmung(A).In the packing position (cf. FIG. 1), the balloon (3) and the stabilizing screen (4) located in it are stowed in the receiving space (2). After the release of the submunition (1), a pulse is given to the gas generator (11) after a certain time. This then inflates the balloon (3). The submunition (1) is exposed to an inflow (A) (see FIG. 2). When the balloon (3) is inflated, the stabilizing screen (4) is pulled out of the receiving space (2) by the balloon (3) (cf. FIG. 2). The inflated balloon (3) stabilizes the flight position of the submunition (1) in the inflow (A).

Unter der weiteren Wirkung des Gasgenerators (11) reißt das Ballonoberteil(9) an der Sollbruchlinie(8) vom Ballonunterteil(10). Es ist nun der Stabilisierungsschirm(4) selbst der Anströmung(A) ausgesetzt, so daß er sich entfaltet (vgl. Figur 3) und den Flug der Submunition(1) stabilisiert und bremst. Bei der beschriebenen Einrichtung ist das Ausziehen und Auffalten des Stabilisierungsschirms(4) sicher gewährleistet.Under the further action of the gas generator (11), the balloon upper part (9) tears at the predetermined breaking line (8) from the balloon lower part (10). The stabilizing screen (4) itself is now exposed to the inflow (A), so that it unfolds (see FIG. 3) and stabilizes and brakes the flight of the submunition (1). With the described device, pulling out and unfolding the stabilizing screen (4) is guaranteed.
