Description

Die Erfindung betrifft ein Scheinziel für ein Luftfahrzeug zur Abwehr infrarotgesteuerter Flugkörper.The invention relates to a decoy target for an aircraft for repelling infrared-controlled missiles.

Zur Abwehr infrarotgesteuerter Flugkörper werden Luftfahrzeuge mit Scheinzielen, sogenannten Flares ausgestattet. Die Scheinziele enthalten Wirkmassen, die beim Abbrand eine die Infrarotsteuerung der Flugkörper störende IR-Signatur erzeugen.To ward off infrared-controlled missiles, aircraft are equipped with decoys, so-called flares. The decoys contain effective masses which generate a IR signature disturbing the infrared control of the missiles during burnup.

E.-C. Koch, A. Dochnahl, IR Emission Behavior of Magnesium/Teflon/Viton, Propellants, Explosives, Pyrotechnics 25 2000, 37 offenbart eine Wirkmasse, die beim Abbrand ein einem Schwarzkörper ähnliches Spektrum erzeugen, wie Magnesium/Teflon/Viton (MTV).E.-C. Koch, A. Dochnahl, IR Emission Behavior of Magnesium / Teflon / Viton, Propellants, Explosives, Pyrotechnics 25 2000, 37 discloses an active mass which upon burning produces a spectrum similar to a blackbody, such as Magnesium / Teflon / Viton (MTV).

Ferner sind Wirkmassen bekannt, die beim Abbrand ein selektives, z. B. H2O und CO2 ähnliches Spektrum erzeugen (E.C. Koch Pyrotechnic Countermeasures: II. Advanced Aerial Infrared Countermeasures, Propellants, Explosives, Pyrotechnics 31 2000, 3). Mittels solcher spektraler Wirkmassen können infrarotgesteuerte Flugkörper mit selektiver Diskrimierung für die vom Triebwerk des Luftfahrzeugs abgestrahlte Infrarotstrahlung abgewehrt werden.Furthermore, active compounds are known which burn when burning a selective, z. B. H 2 O and CO 2 produce similar spectrum (EC Koch Pyrotechnic Countermeasures: II. Advanced Aerial Infrared Countermeasures, Propellants, Explosives, Pyrotechnics 31 2000, 3). By means of such spectral active compositions infrared-controlled missiles with selective discrimination for the radiated from the engine of the aircraft infrared radiation can be repelled.

Aus der GB 2 327 116 A ist ein Scheinziel für einen Hubschrauber bekannt. Dieses Scheinziel umfasst ein Gehäuse, in dem drei MTV-Wirkmassen vorgesehen sind. Die Wirkmassen werden nacheinander mit einer vorbestimmten Verzögerung gezündet. Dadurch kann die Schutzdauer für den Hubschrauber verlängert werden. Für die Abwehr infrarotgesteuerter Flugkörper mit selektiver Diskriminierung ist das in der GB 2 327 116 A offenbarte Scheinziel allerdings nicht geeignet.From the GB 2 327 116 A is a decoy known for a helicopter. This decoy comprises a housing in which three MTV active materials are provided. The active materials are ignited in succession with a predetermined delay. This can extend the protection period for the helicopter. For the defense of infrared controlled missiles with selective discrimination that is in the GB 2 327 116 A disclosed decoy, however, not suitable.

Aufgabe der Erfindung ist es, die Nachteile nach dem Stand der Technik zu beseitigen. Es soll insbesondere ein Scheinziel angegeben werden, mit welchem infrarotgesteuerte Flugkörper mit selektiver Diskriminierung mit verbesserter Wirksamkeit abgewehrt werden können.The object of the invention is to eliminate the disadvantages of the prior art. In particular, a decoy target is to be specified with which infrared-controlled missiles with selective discrimination can be averted with improved effectiveness.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen ergeben sich aus den Merkmalen der Ansprüche 2 bis 5.This object is solved by the features of claim 1. Advantageous embodiments result from the features of claims 2 to 5.

Nach Maßgabe der Erfindung ist ein Scheinziel vorgesehen, wobei in einer Patrone zumindest zwei Wirkmassen aufgenommen sind, wobei eine erste Wirkmasse beim Abbrand ein einem Schwarzkörper ähnliches Spektrum erzeugt und wobei eine zweite Wirkmasse beim Abbrand ein von der ersten Wirkmasse verschiedenes, im Wesentlichen H2O und CO2 ähnliches Spektrum erzeugt, und wobei eine Ausstoßeinrichtung zum zeitlich versetzten Ausstoß der ersten und der zweiten Wirkmasse aus der Patrone vorgesehen ist, wobei die Ausstoßeinrichtung derart ausgestaltet ist, dass beim Zünden zuerst die erste Wirkmasse und nachfolgend die zweite Wirkmasse aus der Patrone ausgestoßen wird, und wobei die zweite Wirkmasse mit einem Bremsmittel zum Abbremsen der Fallgeschwindigkeit versehen ist.According to the invention, a decoy is provided, wherein in a cartridge at least two active masses are added, wherein a first active mass produced during burning a blackbody similar spectrum and wherein a second active mass during combustion one of the first active mass different, essentially H 2 O. and CO 2 produced similar spectrum, and wherein an ejection device is provided for time-staggered discharge of the first and second active mass from a cartridge, wherein the ejector is configured such that upon firing first the first active mass and subsequently discharged, the second active mass from the cartridge is, and wherein the second active mass is provided with a braking means for decelerating the falling speed.

Nach dem Gegenstand der vorliegenden Erfindung werden vorteilhafterweise mehrere unterschiedlich wirkende Wirkmassen in einer Patrone aufgenommen. Mit einem solchen Scheinziel bzw. Hybridscheinziel können unterschiedliche Typen infrarotgesteuerter Flugkörper abgewehrt werden. Die Fallgeschwindigkeit der zweiten Wirkmasse wird durch das Bremsmittel abgebremst. Beim Einsatz wird das von der zweiten Wirkmasse erzeugte, im Wesentlichen H2O und CO2 ähnliche Spektrum räumlich zwischen dem von der ersten Wirkmasse erzeugten Schwarzkörper-ähnlichen Spektrum und dem Luftfahrzeug erzeugt. Dadurch können bestimmte Bedrohungen besonders effizient abgewehrt werden.According to the subject matter of the present invention, advantageously a plurality of differently acting active compositions are received in a cartridge. With such a decoy or hybrid target different types of infrared-controlled missile can be repelled. The falling speed of the second active mass is decelerated by the braking means. During use, the spectrum produced by the second active mass, substantially similar to H 2 O and CO 2, is generated spatially between the blackbody-like spectrum generated by the first active mass and the aircraft. As a result, certain threats can be repelled particularly efficiently.

Nach einer vorteilhaften Ausgestaltung ist zum Zünden eine elektrische Zündvorrichtung mit Rohrsicherung vorgesehen. Die Rohrsicherung stellt sicher, dass die Wirkmassen erst außerhalb der Patrone abbrennen. Damit wird eine Beschädigung an der Ausstoßvorrichtung bzw. am Luftfahrzeug verhindert.According to an advantageous embodiment, an electric ignition device with pipe protection is provided for igniting. The pipe lock ensures that the active masses only burn off outside the cartridge. This prevents damage to the ejection device or on the aircraft.

Nach einer weiteren Ausgestaltung ist das Bremsmittel ein an der zweiten Wirkmasse angebrachter Fallschirm oder ein Band. Derartige Bremsmittel sind einfach, effizient und kostengünstig.According to a further embodiment, the braking means is attached to the second active mass parachute or a band. Such braking means are simple, efficient and inexpensive.

Vorteilhafterweise ist das Bremsmittel aus einem brennbaren Material hergestellt. Ein derartiges Bremsmittel verbrennt zusammen mit der zweiten Wirkmasse. Damit kann die Effizienz des Scheinziels weiter erhöht werden.Advantageously, the braking means is made of a combustible material. Such a brake means burns together with the second active mass. Thus, the efficiency of the decoy can be further increased.

Nach einer weiteren Ausgestaltung ist die erste Wirkmasse so ausgelegt, dass sie eine kürzere Brenndauer als die zweite Wirkmasse aufweist. Auch dieses Merkmal trägt zur Verbesserung der Abwehr infrarotgesteuerter Flugkörper bei.According to a further embodiment, the first active mass is designed so that it has a shorter burning time than the second active mass. This feature also contributes to improving the defense of infrared-controlled missiles.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung in Verbindung mit der einzigen Figur beschrieben, welche schematisch den Aufbau eines erfindungsgemäßen Hybridscheinziels zeigt.An embodiment of the invention will now be described in connection with the single figure, which shows schematically the structure of a hybrid light target according to the invention.

In Fig. 1 ist schematisch der Aufbau des erfindungsgemäßen Hybridscheinziels dargestellt. Das Hybridscheinziel umfasst eine Patrone 1. In der Patrone 1 sind hintereinander eine erste Wirkmasse 2, z. B. eine MTV-Wirkmasse, und eine zweite Wirkmasse 3 angeordnet, welche beim Abbrand ein H2O und CO2 ähnliches Spektrum erzeugt. Die zweite Wirkmasse 3 ist mit einem Bremsmittel 4 versehen. Das Bremsmittel 4 ist hier schematisch dargestellt. Es kann z. B. ein Fallschirm oder ein Band sein. Das Hybridscheinziel umfasst ferner eine Ausstoßeinrichtung 5. Die Ausstoßeinrichtung 5 ist als elektrisch initiierbare Impulskartusche zum Ausstoßen und Zünden der ersten 2 und der zweiten Wirkmasse 3 ausgebildet. Ferner ist eine Rohrsicherung 6 vorgesehen. Das Hybridscheinziel weist an einem der Ausstoßeinrichtung 5 gegenüberliegenden Ende einen Patronenabschluss 7, wie eine Abdeckung oder dgl., auf.In Fig. 1 the structure of the hybrid light target according to the invention is shown schematically. The hybrid light target comprises a cartridge 1. In the cartridge 1 are successively a first active mass 2, z. As an MTV active mass, and a second active mass 3, which generates a H 2 O and CO 2 similar spectrum during combustion. The second active mass 3 is provided with a braking means 4. The braking means 4 is shown schematically here. It can, for. As a parachute or a band. The hybrid light target further comprises an ejector 5. The ejector 5 is formed as an electrically initiatable pulse cartridge for ejecting and igniting the first 2 and the second active mass 3. Furthermore, a pipe lock 6 is provided. The hybrid light target has a cartridge end 7, such as a cover or the like, at an end opposite to the ejector 5.

Die Funktion des erfindungsgemäßen Hybridscheinziels ist wie folgt:The function of the hybrid light target according to the invention is as follows:

Beim Einsatz des erfindungsgemäßen Hybridscheinziels wird die Ausstoßeinrichtung 5 elektrisch ausgelöst. Durch den entstehenden Druck werden die erste 2 und die zweite Wirkmasse 3 in Richtung des Patronenabschlusses 7 bewegt. Zunächst wird die erste Wirkmasse 2, anschließend die zweite Wirkmasse 3 aus der Patrone 1 ausgestoßen. Durch die Rohrsicherung 6 wird in an sich bekannter Weise sichergestellt, dass die Wirkmassen 2, 3 erst nach dem Ausstoß, außerhalb des Luftfahrzeugs abbrennen.When using the hybrid light target according to the invention, the ejector 5 is triggered electrically. Due to the resulting pressure, the first 2 and the second active mass 3 are moved in the direction of the cartridge end 7. First, the first active mass 2, then the second active mass 3 is ejected from the cartridge 1. By means of the pipe safety device 6, it is ensured in a manner known per se that the active masses 2, 3 do not burn off outside of the aircraft until after the ejection.

Außerhalb des Luftfahrzeugs wird die zweite Wirkmasse 3 durch das Bremsmittel 4 abgebremst, während sich die erste Wirkmasse 2 mit einer vergleichsweise höheren Geschwindigkeit vom Luftfahrzeug entfernt. Dieser Effekt kann ferner durch die jeweilige Form der Wirkmassen 2, 3 verstärkt werden. Z. B. kann die erste Wirkmasse 2 mit einem kleinen Oberfläche/Volumen-Verhältnis und die zweite Wirkmasse mit einem großen Oberfläche/Volumen-Verhältnis ausgeführt wird. Z. B. kann die erste Wirkmasse die Form einer Kugel, eines Würfels oder eines Quaders haben, wohingegen die zweite Wirkmasse z. B. in Form einer flachen Platte oder Scheibe ausgeführt sein kann. Wegen der unterschiedlichen Fallgeschwindigkeiten der Wirkmassen 2, 3 befindet sich demnach das im Wesentlichen H2O und CO2 ähnliche Spektrum der zweiten Wirkmasse 3 zwischen dem Schwarzkörper-ähnlichen Spektrum der ersten Wirkmasse 2 und dem Luftfahrzeug. Die Brenndauer der ersten Wirkmasse 2 ist kürzer als die Brenndauer der zweiten Wirkmasse 3. Das Bremsmittel 4 ist aus einem brennbaren Material hergestellt und verbrennt zusammen mit der zweiten Wirkmasse 3.Outside the aircraft, the second active mass 3 is decelerated by the braking means 4, while the first active mass 2 with a relatively higher speed away from the aircraft. This effect can be further enhanced by the respective shape of the active masses 2, 3. For example, the first active mass 2 with a small surface / volume ratio and the second active mass with a high surface / volume ratio is performed. For example, the first active mass may have the shape of a ball, a cube or a cuboid, whereas the second active mass z. B. may be in the form of a flat plate or disc. Because of the different falling speeds of the active masses 2, 3, the substantially H 2 O and CO 2- like spectrum of the second active mass 3 is therefore located between the blackbody-like spectrum of the first active mass 2 and the aircraft. The burning time of the first active mass 2 is shorter than the burning time of the second active mass 3. The braking means 4 is made of a combustible material and burns together with the second active mass 3.

Das beschriebene Hybridscheinziel eignet sich insbesondere für Hubschrauber, kann jedoch auch in anderen Luftfahrzeugen eingesetzt werden.The hybrid light target described is particularly suitable for helicopters, but can also be used in other aircraft.
