Description

Die Erfindung betrifft einen Nebelwurfkörper mit einer Wirkladung aus einer pyrotechnischen Wirkmasse zur Erzeugung eines im Infraroten emittierenden und im Visuellen undurchdringlichen Aerosols.The invention relates to a smoke throwing body with an active charge a pyrotechnic active material for generating one in the infrared emissive and visually impenetrable aerosols.

Ein solcher körper ist aus der US 5 337 671 A bekannt.Such a body is known from US 5 337 671 A.

Gepanzerte und ungepanzerte Fahrzeuge werden mittels Aerosolvorhängen gegen Entdeckung, Erfassung und Zielverfolgung und damit gegen die Bedrohung durch Flugkörper geschützt.Armored and unarmored vehicles are used by Aerosol curtains against detection, detection and tracking and thus protected against the threat of missiles.

In der DE 199 14 097 A1 ist eine geeignete pyrotechnische Wirkmasse zur Erzeugung eines im Infraroten stark emissiven und im Visuellen undurchdringlichen Aerosols beschrieben. Diese Wirkmasse entwickelt einen Tarnnebel, der neben der Undurchdringlichkeit im sichtbaren Bereich auch eine lang anhaltende Deckung im Infrarotbereich ermöglicht. Diese Wirkmasse enthält als Hauptbestandteile roten Phosphor, ein Alkalimetallnitrat oder eine Mischung von Alkalimetallnitraten und als Nebenbestandteile mindestens ein Übergangsmetall bzw. eine metallische Verbindung oder Legierung desselben, mindestens ein Metalloid sowie einen Binder.In DE 199 14 097 A1 is a suitable pyrotechnic active material for generating a highly emissive in the infrared and in the visual impenetrable aerosol described. This active mass developed a camouflage fog, in addition to the impenetrability in the visible Range also a long-lasting coverage in the infrared range allows. This active material contains red as the main components Phosphorus, an alkali metal nitrate or a mixture of Alkali metal nitrates and as minor components at least one Transition metal or a metallic compound or alloy the same, at least one metalloid and a binder.

Da die bedrohenden Flugkörper mit Geschwindigkeiten von 200 bis 600 m/s anfliegen, muss nach ihrer Erkennung eine Vernebelung sehr schnell stattfinden. Bekannte Wurfkörper entfalten ihre Wirkung jedoch erst nach einer Flugzeit und Zeitverzögerung von beispielsweise 2 s. In dieser Zeit ist das Fahrzeug ungeschützt.Because the threatening missiles with speeds of 200 to 600 m / s approach, after their detection, a nebulization very take place quickly. However, known projectiles unfold their effect only after a flight time and time delay of, for example, 2 s. In At this time the vehicle is unprotected.

In der DE 29 08 217 C2 ist eine Einheitsladung zur Vernebelung von Fahrzeugen beschrieben, welche eine mit Nebelkörpern gefüllte Hülse aufweist. Die Nebelkörper weisen die Form zylindrischer aufeinanderliegender flacher Scheiben mit offenem Mittlloch auf. Die Nebelkörper werden ohne Umhüllung aus der Hülse ausgeworfen. Eine Überblendung der Sichtlinie im infraroten Bereich ist nicht vorgesehen.In DE 29 08 217 C2 is a unit charge for nebulization of Vehicle described which a filled with fog bodies sleeve having. The mists are cylindrical in shape on top of each other flat slices with open center hole. The Mist bodies are ejected without wrapping from the sleeve. A Crossfading of the line of sight in the infrared range is not provided.

Aufgabe der Erfindung ist es, einen einfach aufgebauten Nebelwurfkörper vorzuschlagen, der so gestaltet ist, dass es beim Ausstoß in einem Raumwinkel zu einer schnellen Überblendung der Sichtlinie im infraroten Strahlungsbereich und im visuellen Strahlungsbereich kommt.The object of the invention is to provide a simple structure To propose a smoke-throwing body that is designed to Output in a solid angle to a quick crossfade of the Line of sight in the infrared radiation range and in the visual Radiation area comes.

Erfindungsgemäß ist obige Aufgabe durch die Merkmale des Patentanspruchs 1 gelöst.According to the above object by the features of Patent claim 1 solved.

Der aus den Hohlzylindersegmenten bestehende Wirkladungsstapel wird von der Umhüllung gehalten aus einem Werferrohr ausgeworfen, wodurch in der Anfangsphase des Flugs eine aerodynamische Stabilität gewährleistet ist. Dadurch ist verhindert, dass sich der Stapel schon unmittelbar beim Fahrzeug auffaltet. Erst nach einigen Flugmetern, beispielsweise 5 m bis 10 m, brechen die angezündeten Hohlzylindersegmente die Umhüllung auf. Durch die nun fehlende aerodynamische Verkleidung greift die angeströmte Luft in den Stapel der Hohlzylindersegmente. Dadurch werden die Segmente sofort auseinandergetrieben, was zu einer großflächigen Auffächerung der brennenden Hohlzylindersegmente in einem weiten Raumwinkel führt. Dadurch wird sehr schnell, beispielsweise innerhalb von 0,25 s, eine Aerosolnebelverteilung geschaffen, die das Fahrzeug sowohl gegen horizontal als auch im Gleitflug anfliegende Flugkörper im Infrarotstrahlungsbereich und im visuellen Strahlungsbereich verdeckt. Im Fahrzeug steht damit eine im Vergleich zum Stand der Technik lange Zeit zur Verfügung, um durch Fahrmanöver dem im Fahrzeug errechneten Einschlagzeitpunkt des anfliegenden Flugkörpers auszuweichen.The existing of the hollow cylinder segments effective charge stack is ejected from the shroud ejected from a launcher tube, giving aerodynamic stability in the initial phase of the flight is guaranteed. This prevents the stack already immediately unfolds at the vehicle. Only after a few meters, For example, 5 m to 10 m, break the lighted Hollow cylinder segments on the envelope. By now missing Aerodynamic fairing attacks the inflated air in the stack the hollow cylinder segments. This will make the segments immediate dislocated, resulting in a large-scale diversification of the burning hollow cylinder segments leads in a wide solid angle. This is very fast, for example, within 0.25 s, one Created aerosol mist distribution, which the vehicle against both horizontal as well as in gliding approaching missiles in Infrared radiation area and hidden in the visual radiation area. In the vehicle is thus a long compared to the prior art Time available to maneuver in the vehicle calculated impact time of the approaching missile dodge.

    Die Hohlzylindersegmente 6 sind aus einer pyrotechnischen Wirkmasse gestaucht, die einen im infraroten Strahlungsbereich dämpfenden und emittierenden, sowie im Visuellen undurchdringlichen Aerosol erzeugen. Eine derartige Wirkmasse ist in der DE 199 14 097 A1 beschrieben. Sie weist als Hauptbestandteile roten Phosphor, ein Alkalimetallnitrat oder eine Mischung von Alkalimetallnitraten und als Nebenbestandteile mindestens ein Übergangsmetall, bzw. eine metallreiche Verbindung oder Legierung desselben und mindestens ein Metalloid sowie einen Binder auf.The hollow cylinder segments 6 are made of a pyrotechnic active mass upset, which dampens one in the infrared radiation range and emissive as well as produce in the visual impenetrable aerosol.

    Die Umhüllung 4 weist eine verbrennliche Folie 8 auf, die beispielsweise aus einem mit Parafin getränkten Papier besteht. Die Folie 8 hält anfänglich den aus den Hohlzylindersegmenten 6 bestehenden Wirkladungsstapel 2 zusammen. Die Folie 8 umhüllt den Wirkladungsstapel 2 an der Oberseite und an seinem dem Durchmesser D entsprechenden Umfang U in der gesamten Höhe H. Figur 5 zeigt die Folie 8 abgewickelt. Die Folie 8 ist mit einer Scheibe 9 verbunden, die an der Unterseite der Wirkladung 2 anliegt.The envelope 4 has a combustible film 8, for example made of paper impregnated with paraffin. The foil 8 stops initially consisting of the hollow cylinder segments 6 Wirkladungsstapel 2 together.

Fig. 1, Fig. 4).The disc 9 is made of a press fiber material and has a central opening 10 on. The diameter d1 of the Aperture 10 is ≥ the diameter d (see Fig. 1, Fig. 4).

    Der beschriebene Nebelwurfkörper ist in ein metallisches Auswerferrohr 11 einsetzbar (vgL Fig. 6). Figur 6 zeigt die Anordnung in auseinandergezogenem Zustand. Am Boden 12 des Auswerferrohres 11 ist ein elektrisches Anzündelement 13 angeordnet, dessen elektrischen Kontakte 14 über eine entsprechende Schalteinrichrung des Fahrzeugs aufschließbar sind. Das Anzündelement 13 zündet bei Initiierung die Anzündladung 3 an, die zugleich als Ausstoßladung wirken kann.The described fogging body is in a metallic ejector tube 11 can be used (vgL Fig. 6). FIG. 6 shows the arrangement in FIG exploded state. At the bottom 12 of the ejector 11th an electric ignition element 13 is arranged, the electrical Contacts 14 via a corresponding Schalteinrichrung of the vehicle are unlockable. The ignition element 13 ignites upon initiation the Anzündladung 3, which can act as a discharge charge at the same time.

    Erfolgt die Anzündung, dann werden die Hohlzylindersegmente 6 angezündet und der Nebelwurfkörper 1 wird ausgeworfen. Im Bereich zwischen etwa 5 bis 10 m nach dem Beginn der Gasentwicklung des Ausstoßes bleiben die Hohlzylindersegmente 6 von der Folie 8 zusammengehalten. Nach Abbrand der Folie 8, etwa 5 bis 10 m nach dem Verlassen des fahrzeuggebundenen Auswerferrohres 11, fächert sich der Wirkladungsstapel 2 unter Vereinzelung der Hohlzylindersegmente 6 auf und die einzelnen Hohlzylindersegmente 6 entwickeln nach einer Strecke S in Abstand von dem zu schützenden Fahrzeug F einen Nebelvorhang N, der das Fahrzeug F sowohl gegen im Gleitflug bedrohende Flugkörper K1 als auch im Horizontalnug angreifende Flugkörper K2 abschirmt (vgl. Fig. 7).If the ignition, then the hollow cylinder segments 6 lit and the smoke throwing body 1 is ejected. In the area between about 5 to 10 m after the beginning of the gas evolution of the Ejection remain the hollow cylinder segments 6 of the film. 8 held together. After burning of the film 8, about 5 to 10 m after leaving the vehicle-mounted ejector tube 11 fans the random charge stack 2 under separation of the Hollow cylinder segments 6 and the individual hollow cylinder segments. 6 develop after a distance S at a distance from the one to be protected Vehicle F a fog curtain N, the vehicle F against both in Gliding-threatening missile K1 as well as in Horizontalnug shielding missile K2 shields (see Fig. 7).

    Die Entwicklung des schützenden Nebels N erfolgt beispielsweise innerhalb von 0,25 s nachdem das Fahrzeug F die Bedrohung durch die Flugkörper K1 und K2 erkannt und ausgewertet hat.The development of the protective mist N takes place, for example within 0.25 s after the vehicle F is threatened by the Missile K1 and K2 has been detected and evaluated.

    Figur 8 zeigt einen Vergleich bekannter Wirkungszeiten und der durch den erfindungsgemäßen Wurfkörper erreichbaren Wirkungszeit. Zum Zeitpunkt t0 wird vom Fahrzeug F die Bedrohung durch einen anfliegenden Flugkörper erkannt und damit ein Auswurf der Vernebelungseinrichtung ausgelöst, der dann zum Zeitpunkt t1 erfolgt. t4 ist der Zeitpunkt, bei dem nach der Berechnung des Fahrzeugs F der bedrohende Flugkörper einschlägt.Figure 8 shows a comparison of known action times and by the impact length achievable according to the invention. To the Time t0 is the threat of a vehicle F recognized flying missile and thus an ejection of the Nebulizer triggered, which then takes place at time t1. t4 is the time at which after calculation of the vehicle F the threatening missile strikes.

    Nach dem Stand der Technik wird die der Bedrohung entgegenwirkende Nebelentwicklung W nach der Linie a zum Zeitpunkt t3 erreicht, wogegen das mit der beschriebenen Einrichtung erreichte Wirkungsniveau bereits in der Linie b zum Zeitpunkt t2 erreicht wird. Dabei zeigt sich, dass die Zeitspanne zwischen t3 und t4 wesentlich kleiner ist als die Zeitspanne zwischen t2 und t4. Dies besagt, dass zwischen t2 und t4 im bedrohten Fahrzeug eine wesentlich länger Zeit für der Bedrohung ausweichende Fahrmanöver zur Verfügung steht als zwischen dem Stand der Technik, bei dem für ausweichende Fahrmanöver nur die Zeit zwischen t3 und t4 zur Verfügung steht.According to the state of the art, the counteracts the threat Fog development W after line a reached at time t3, whereas that achieved with the described device Level of effect is already reached in line b at time t2. It shows that the time span between t3 and t4 is significant is less than the time span between t2 and t4. This states that between t2 and t4 in the threatened vehicle a much longer time for the threat evasive driving maneuver is available as between the prior art, in which for evasive Driving maneuvers only the time between t3 and t4 is available.
