Description

Die vorliegende Erfindung betrifft einen Nebelwurfkörper gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a smoke throwing body according to the preamble of claim 1.

Derartige Nebelwurfkörper sind dazu vorgesehen, einen Nebelvorhang zu bilden, um damit Fahrzeuge oder Truppen gegen Entdeckung, Erfassung und Zielverfolgung zu schützen. Üblicherweise werden Nebelwurfkörper an einem gepanzerten Fahrzeug in einer Mehrzahl von Auswerferrohren mitgeführt und bei Bedarf durch Zünden einer Treibladung in einer Flugbahn, die durch die Winkeleinstellung des Auswerferrohres festgelegt ist, ausgeschleudert. Etwas zeitverzögert erfolgt dann aufgrund eines pyrotechnischen Zerlegers ein Verbrennen des Nebelstoffs und damit die Erzeugung eines Nebelvorhangs.Such smoke projectiles are intended to form a fog curtain to protect vehicles or troops against detection, detection and target tracking. Usually, smoke projectiles are carried on an armored vehicle in a plurality of ejector tubes and, if necessary, ejected by igniting a propellant charge in a trajectory defined by the angular setting of the ejector tube. Somewhat time-delayed, the result is then a burning of the smoke material and thus the generation of a fog curtain due to a pyrotechnic decomposer.

Die DE 20 2006 003 023 U1 beschreibt einen gattungsgemäßen Nebelwurfkörper, der in einer Dose einen Stapel übereinander angeordneter Nebeltabletten aufweist, der in der Dose über einem Treibspiegel und der Abschlussscheibe angeordnet ist. Zum Anzünden der Nebeltabletten ist in einem zentralen Längskanal eine Anzündlitze vorgesehen. Nach dem Auswerfen des Nebelwurfkörpers sorgt die Anzündlitze für ein Anzünden der Nebeltabletten und damit für die Ausbildung einer Nebelwand. Das Problem besteht jedoch darin, dass bei einem zu großen Einstellwinkel, d. h. bei zu steiler Stellung des Auswerferrohres, die Ausbildung der Nebelwand zu hoch einsetzt, so dass das Fahrzeug aus einem flacheren Beobachtungswinkel länger sichtbar und damit ungeschützt bleibt.The DE 20 2006 003 023 U1 describes a generic smoke throwing body having a stack of superposed mist tablets in a can, which is arranged in the box above a sabot and the lens. To ignite the mist tablets a Anzündlitze is provided in a central longitudinal channel. After the ejection of the smoke-throwing body, the Anzündlitze provides for lighting the fog tablets and thus for the formation of a smoke screen. The problem, however, is that if the setting angle is too great, ie if the ejector tube is too steep, the formation of the smoke screen will be too high, so that the vehicle will remain visible longer from a shallower viewing angle and thus remain unprotected.

Aus der WO 03/106913 A1 ist ein Nebelwurfkörper bekannt, der eine Mehrzahl von Lagen von Nebeltabletten aufweist, die über eine unterseitige pyrotechnische Wirkladung abgebrannt werden. Dies führt dazu, dass aufgrund der Stapelbildung die einzelnen, entzündeten Nebeltabletten einzeln zeitlich nacheinander entlang der ballistischen Flugbahn des Nebelwurfkörpers verbrennen. Das Problem besteht jedoch hierbei darin, dass aufgrund des Verbrennens der einzelnen Nebeltabletten bedingt sukzessive lediglich kleine Nebelschwaden erzeugt werden. Hinzu kommt das Problem, dass die hierdurch gebildete Nebelwand eine vergleichsweise geringe Nebeldichte aufweist.From the WO 03/106913 A1 For example, a smoke throwing device is known which comprises a plurality of layers of mistletoe tablets which are burnt off via a pyrotechnic active charge on the underside. This leads to the fact that due to the stacking individually, one after the other, burn individual, inflamed mists of pollen one after the other along the ballistic trajectory of the smoke throwing body. However, the problem here is that caused due to the burning of the individual fog tablets due successively only small nets. In addition, there is the problem that the fog wall formed thereby has a comparatively low mist density.

Die US 4 791 870 A1 beschreibt einen weiteren Nebelwurfkörper gemäß dem Oberbegriff des Anspruchs 1. Dieser Nebelwurfkörper stellt den Ausgangspunkt für die vorliegende Erfindung dar.The US 4,791,870 A1 describes another smoke throwing body according to the preamble of claim 1. This smoke throwing body is the starting point for the present invention.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen neuartigen Nebelwurfkörper zur Verfügung zu stellen, der eine effektive Nebelwand mit hoher Nebeldichte in kürzester Zeit gewährleistet. Die vorliegende Aufgabe wird bei dem gattungsgemäßen Nebelwurfkörper dadurch gelöst, dass mehrere, voneinander getrennte pyrotechnische Zerlegerladungen vorgesehen sind, die eine Nebelerzeugung und wirksame Verteilung des erzeugten Nebels zu unterschiedlichen, aufeinander folgenden Zeitpunkten bewirken. Der neuartige Nebelwurfkörper ermöglicht es aufgrund der voneinander getrennten pyrotechnischen Zerlegerladungen, die mit zugehörigen Modulen von Nebelstoff zusammenwirken, dass unmittelbar, d. h. in sehr kurzer Zeit nach dem Ausstoß eine durch die erste pyrotechnische Zerlegerladung entstehende erste Nebelwand mit hoher Nebeldichte ausgebildet wird und anschließend, etwas zeitverzögert, die Ausbildung der zweiten Nebelwand erfolgt. Hierdurch wird eine Vernebelung mit hoher Nebeldichte in sehr kurzer Zeit gewährleistet, die auch aus verschiedenen Beobachtungswinkeln wirkungsvoll ist.The present invention has for its object to provide a novel smoke throwing available that ensures an effective smoke screen with high fog density in no time. The present object is achieved in the generic smoke throwing body in that a plurality of separate pyrotechnic Zerlegerladungen are provided which cause fog generation and effective distribution of the fog generated at different, successive times. Due to the separate pyrotechnic decomposer charges, which cooperate with associated modules of mist material, the novel smoke-impact body makes it possible to directly, d. H. in a very short time after ejection, a first fog wall having a high fog density, which is formed by the first pyrotechnic disintegrating charge, is formed and then, with a time delay, the second fog wall is formed. As a result, a nebulization with high fog density is ensured in a very short time, which is effective even from different viewing angles.

Konstruktiv kann dies dadurch in einfacher Weise gelöst werden, dass mindestens eine erste und zweite Kammer vorgesehen sind, wobei jede Kammer Nebelstoff enthält und jeder Kammer eine eigene pyrotechnische Zerlegerladung zugeordnet ist.Constructively, this can be achieved in a simple manner that at least a first and second chamber are provided, each chamber contains smoke and each chamber is assigned its own pyrotechnic bursting charge.

Dadurch, dass sich die Kammern sowie Zerlegerladungen entlang der Längsachse des Nebelwurfkörpers befinden, kann ein entsprechender sandwichartiger Aufbau zur Gewährleistung der zeitversetzten Wirksamkeit in einfacher Weise realisiert werden.Characterized in that the chambers and Zerlegerladungen along the longitudinal axis of the smoke thrown body, a corresponding sandwich-like structure to ensure the time-delayed effectiveness can be realized in a simple manner.

Sofern die jeweilige Zerlegerladung in einem zugehörigen, vorzugsweise im Bereich der Längsachse befindlichen Längskanal des Nebelwurfkörpers untergebracht ist, steht die Zerlegerladung umfänglich über deren gesamter Länge mit dem Nebelstoff in Kontakt und ermöglicht hierdurch eine äußerst schnelle Verbrennung und damit Nebelbildung.If the respective bursting charge is accommodated in an associated longitudinal channel, located preferably in the region of the longitudinal axis, of the smoke throwing body, the bursting charge is circumferentially in contact with the smoke substance over its entire length, thereby enabling extremely rapid combustion and thus fog formation.

Zweckmäßigerweise befindet sich zwischen den beiden Kammern eine Trennwand, die die Zeitverzögerung beim Abbrennen der beiden Kammern noch unterstützt.Conveniently, there is a partition between the two chambers, which still supports the time delay during the burning of the two chambers.

Erfindungsgemäß ist eine der beiden Zerlegerladungen mit Mittel zu einem zeitverzögerten Wirksamwerden der Zerlegerladung versehen. Hierdurch kann eine gemeinsame elektrische Zündeinrichtung für beide Zerlegerladungen verwendet und ein einfacher Aufbau realisiert werden. Gleichwohl werden die beiden Zerlegerladungen zeitversetzt wirksam. Die vorliegende Erfindung ist dadurch gekennzeichnet, dass als Mittel zu einem zeitverzögerten Wirksamwerden der Zerlegerladung eine Umhüllung, beispielsweise Verdämmung, vorgesehen ist, die die Zerlegerladung vollständig oder teilweise umgibt. Sie sorgt dafür, dass sich das bereits entzündete Material der Zerlegerladung nicht sofort ausbreiten und auf den Nebelstoff einwirken kann.According to the invention, one of the two burster charges is provided with means for a time-delayed activation of the burster charge. As a result, a common electric ignition device can be used for both Zerlegerladungen and a simple structure can be realized. Nevertheless, the two Zerlegerladungen be effective with a time delay. The present invention is characterized in that as a means for a time-delayed effect of the Zerlegerladung an envelope, such as confinement, is provided which completely or partially surrounds the Zerlegerladung. It ensures that the already ignited material of the burster charge can not spread immediately and act on the fog material.

Vorzugsweise sind die Mittel zu einem zeitverzögerten Wirksamwerden der Zerlegerladung so ausgewählt, dass sie rückstandsfrei verbrennen. Es erfolgt damit keine Gefährdung von Truppen durch Metallteile.Preferably, the means for a time-delayed effect of the Zerlegerladung are selected so that they burn residue. There is thus no danger to troops through metal parts.

Beispielsweise kann hierfür als Umhüllung ein organischer, im Wesentlichen rückstandsfrei verbrennender Stoff, beispielsweise Pappe, Kunststoff oder dergleichen, vorgesehen sein.For example, this can be provided as a wrapping an organic, substantially residue-free burning material, such as cardboard, plastic or the like.

Sofern die Umhüllung zudem eine Mehrzahl von Kammern aufweist, wird hierdurch ein zusätzlicher Zeitverzögerungseffekt erreicht.If the enclosure also has a plurality of chambers, this results in an additional time delay effect.

Die Erfindung erlaubt es, als Zerlegerladung gepresste sowie lose, geschüttete pyrotechnische Sätze zu verwenden.The invention makes it possible to use as a disintegrating charge as well as loose, poured pyrotechnic charges.

Eine zweckmäßige Ausgestaltung der vorliegenden Erfindung wird anhand von Zeichnungsfiguren näher erläutert.An expedient embodiment of the present invention will be explained in more detail with reference to drawing figures.

Bezugsziffer 1 bezeichnet den Nebelwurfkörper in seiner Gesamtheit. Er umfasst ein Gehäuse 22. In dem Gehäuse 22 sind eine erste Kammer 3 sowie zweite Kammer 4, die durch eine gemeinsame Trennwand 13 voneinander getrennt sind, vorgesehen.Reference numeral 1 denotes the smoke throwing body in its entirety. It comprises a housing 22. In the housing 22, a first chamber 3 and second chamber 4, which are separated from each other by a common partition wall 13, are provided.

Die erste Kammer 3 sowie zweite Kammer 4 beinhalten jeweils sogenannten Nebelstoff, beispielsweise in Form einer Mehrzahl von in der ersten Kammer 3 sowie zweiten Kammer 4 angeordneten Nebeltabletten. Die Nebeltabletten können beispielsweise in der Art, wie sie in der WO 03/106913 A1 beschrieben sind, ausgebildet sein.The first chamber 3 as well as the second chamber 4 each contain so-called mists, for example in the form of a plurality of fog tablets arranged in the first chamber 3 and the second chamber 4. The fog tablets can, for example, in the way they are in the WO 03/106913 A1 are described, be formed.

Entlang der Längsachse X des Nebelwurfkörpers ist jeweils ein Kanal 11, 12 vorgesehen, welcher zur Aufnahme einer pyrotechnischen ersten Zerlegerladung 5 bzw. zweiten Zerlegerladung 6 dient, wobei eine der Zerlegerladungen zeitverzögert wirkt. Dies wird bei der in Fig. 1 dargestellten Ausführungsform dadurch erreicht, dass die erste Zerlegerladung in dem Kanal 11 angeordnet ist, wohingegen die zweite Zerlegerladung 6 sich innerhalb einer zusätzlichen Umhüllung 7, die vorzugsweise zusätzlich einzelne Kammern 8 aufweisen kann, befindet.Along the longitudinal axis X of the smoke throwing body is in each case a channel 11, 12 is provided which serves to receive a pyrotechnic first Zerlegerladung 5 and second Zerlegerladung 6, wherein one of the Zerlegerladungen time-delayed acts. This will be at the in Fig. 1 illustrated embodiment achieved in that the first Zerlegerladung is disposed in the channel 11, whereas the second Zerlegerladung 6 is within an additional enclosure 7, which may additionally preferably have individual chambers 8.

Die jeweilige Zerlegerladung 5, 6 kann als Hauptbestandteil vorzugsweise loses, geschüttetes Pulver, enthalten. Die Gesamtheit der Zerlegerladungen 5, 6 erstreckt sich gemäß Fig. 1 über die gesamte Höhe des Nebelwurfkörpers 1.The respective burster charge 5, 6 may contain as a main component preferably loose, poured powder. The entirety of the Zerlegerladungen 5, 6 extends according to Fig. 1 over the entire height of the smoke throwing body 1.

Zweckmäßigerweise ist das Material der Umhüllung 7 derart ausgewählt, dass es rückstandsfrei oder zumindest im Wesentlichen rückstandsfrei verbrennt.Conveniently, the material of the envelope 7 is selected such that it burns residue-free or at least substantially residue-free.

Die strichpunktierte Linie in Fig. 1 deutet ein an einem Fahrzeug 16 (vgl. Fig. 2) befindliches Auswerferrohr 14 an. Das Auswerferrohr 14 ist an dem Fahrzeug 16 in einem bestimmten Neigungswinkel positioniert, welcher die Flugbahn des Nebelwurfkörpers festlegt. Im Bereich des Auswerferrohrs 14 befindet sich ein elektronisches Zündelement 15, mit welchem die Treibladung 9 bei Bedarf gezündet werden kann. Die Treibladung 9 dient dazu, einerseits den Auswurf des Nebelwurfkörpers 1 andererseits das Entzünden der Zerlegerladungen 5, 6 zu bewirken.The dash-dotted line in Fig. 1 indicates on a vehicle 16 (see. Fig. 2 ) located ejector tube 14 at. The ejector tube 14 is positioned on the vehicle 16 at a certain angle of inclination, which defines the trajectory of the smoke thrown. In the region of the ejector tube 14 is an electronic ignition element 15, with which the propellant charge 9 can be ignited if necessary. The propellant 9 serves on the one hand to cause the ejection of the smoke throwing body 1 on the other hand, the ignition of the Zerlegerladungen 5, 6.

Fig. 2 zeigt den erfindungsgemäßen Nebelwurfkörper im Einsatz. Der Nebelwurfkörper 1 wird aus dem Auswerferrohr 14 am Fahrzeug 16 durch Zünden der Treibladung entlang einer Flugbahn 17 ausgeschleudert. Hierbei erfolgt nach äußerst kurzer Zeit ein Abbrennen des Nebelstoffs 2 der ersten Kammer 3, wodurch eine Nebelwand 20 unmittelbar vor dem Fahrzeug 16 gebildet wird. Fig. 2 shows the smoke projectile according to the invention in use. The smoke hatch 1 is ejected from the ejector tube 14 on the vehicle 16 by igniting the propellant charge along a flight path 17. In this case, after a very short time a burning of the mist 2 of the first chamber 3, whereby a fog wall 20 is formed immediately in front of the vehicle 16.

Anschließend brennt aufgrund der Umhüllung 7 zeitverzögert der Nebelstoff 2 der zweiten Kammer 4 ebenfalls ab und bildet die in Fig. 2 mit Bezugsziffer 21 gekennzeichnete, weitere Nebelwand. Trotz einer vergleichsweise steil ausgerichteten Positionierung des Auswerferrohrs 14 am Fahrzeug 16 wird sogleich unmittelbar vor dem Fahrzeug eine Nebelwand 20 mit sehr hoher Nebeldichte erzeugt sowie zeitverzögert danach eine weitere Nebelwand 21, so dass der Flugkörper aus verschiedenen Flugbahnen 19 keine Möglichkeit der optischen Ortung mehr hat. Die sich ausbildende, aus den Teilnebelwänden 20, 21 ergebende Gesamtnebelwand zeichnet sich zum einen durch eine sehr schnelle Entstehung zum anderen durch eine sehr hohe Nebeldichte aus. Zudem kann der betreffende Nebelwurfkörper mit sehr einfachen Mitteln hergestellt werden. Da keine Rückstände oder zumindest im Wesentlichen keine Rückstände vorherrschen, besteht keinerlei Gefährdung der Bodentruppen.Then burns due to the envelope 7 time delay of the mists 2 of the second chamber 4 also from and forms the in Fig. 2 marked with reference numeral 21, further smoke screen. Despite a comparatively steeply oriented positioning of the ejector tube 14 on the vehicle 16, a fog wall 20 with a very high fog density is generated immediately ahead of the vehicle and a further fog wall 21 is delayed, so that the missile from different trajectories 19 no longer has any possibility of optical locating. The forming, resulting from the partial mist walls 20, 21 resulting total mist wall is characterized on the one hand by a very rapid emergence to the other by a very high fog density. In addition, the relevant smoke projectile can be produced with very simple means. Since there are no residues or at least essentially no residues, there is no danger to ground troops.

Die vorliegende Erfindung stellt daher einen ganz besonderen Beitrag auf dem einschlägigen Gebiet der Technik dar.The present invention therefore represents a very special contribution in the relevant field of technology.
