Description

Die Erfindung beschäftigt sich mit einem Nebelkörper zur Erzeugung einer Nebelwolke bzw. Nebelwand zum Schutz eines Objektes, Fahrzeugs oder dergleichen vor einer Bedrohung.The invention is concerned with a fog body for generating a cloud of fog or wall for protecting an object, vehicle or the like from a threat.

Herkömmliche pyrotechnische Nebelkörper für Artillerie- und Mörseranwendungen bestehen in der Regel aus Behältern, in denen der pyrotechnische Nebelsatz gepresst wird und einem darauf aufgelegten Deckel mit zumindest einer Ausblasöffnung für den Austritt des bei der Verbrennung entstehenden Nebels. Ein derartiges Nebelgeschoss zeigt beispielsweise die DE 33 39 039 A1 . Im Geschossmantel des Nebelgeschosses sind in Abschussrichtung stapelartig aufeinanderliegend Nebeltöpfe oder Nebelkörper angeordnet, welche nach Abschuss aus diesem Geschossmantel ausgestoßen werden.Conventional pyrotechnic mist bodies for artillery and mortar applications generally consist of containers in which the pyrotechnic mist set is pressed and a cover placed thereon with at least one blow-out opening for the outlet of the mist formed during combustion. Such a smoke bullet shows, for example DE 33 39 039 A1 . In the projectile jacket of the smoke projectile, mist pots or fog bodies are arranged one on top of the other in the firing direction, which are ejected from this projectile jacket after being fired.

Die US 3,685,450 A offenbart einen schwimmenden Granatennapf, um beispielsweise als Rauchschutz oder Markierung für die jeweilige Stelle auf dem Gewässer zu dienen. Bodenseitig weist die Granate eine Schwimmeinrichtung auf. Wenn die Munition vollständig in die Schwimmeinrichtung eingesetzt ist, liegt der Boden der Munition auf dem Ringflansch der Schwimmeinrichtung auf, um einen Raum zwischen dem Boden der Granate und dem Boden der Schwimmeinrichtung zu lassen. Ein Loch im Boden der Schwimmeinrichtung dient dazu, das Entweichen des Granateninhaltes etc. zu ermöglichen. Ein Loch im Granatenboden ist in den Raum zwischen dem Boden der Granate und dem Boden der Schwimmeinrichtung gerichtet. Die Granate sitzt reibschlüssig in der Schwimmeinrichtung. Ein Anschlagmittel dient dazu, zu verhindern, dass die Granate aus der Schwimmeinrichtung getrieben wird, wenn Gase aus dem Loch im Granatenboden in den Zwischenraum entweichen und die Granate gegen das Anschlagmittel getrieben wird.The US 3,685,450 A discloses a floating grenade bowl, for example to serve as smoke protection or marking for the respective location on the water. On the bottom side, the grenade has a floating device. When the ammunition is fully inserted into the buoyancy device, the bottom of the ammunition rests on the ring flange of the buoyancy device to leave a space between the bottom of the grenade and the bottom of the buoyancy device. A hole in the bottom of the floating device serves to allow the grenade contents etc. to escape. A hole in the grenade bottom is directed into the space between the bottom of the grenade and the bottom of the swimming facility. The grenade sits frictionally in the swimming facility. A slinging device serves to prevent the grenade from being driven out of the floating device if gases escape from the hole in the grenade bottom into the intermediate space and the grenade is driven against the slinging device.

In der GB 2 162 621 A wird ein Wurfkörper aus einem elektrisch betätigbaren Kontaktkopf und aus einem daran angeordnete, mit einem Deckel verschlossenen dosenförmigen Wurfmittelbehälter beschrieben. Beim Verschießen des Wurfkörpers wird neben einer Anzündung und Verteilung der in ihm eventuell befindlichen brennbaren Blättchen über eine Zündzerlegereinheit auch ein Presskörper angezündet und zerlegt, wobei gleichzeitig auch eine Wandung des Wurfmittelbbehälters zerlegt wird. Die zu Boden fallenden brennbaren Pellets ziehen einen Nebelvorhang, den sie durch weiteres Abbrennen vom Boden aus nähren.In the GB 2 162 621 A describes a throwing body consisting of an electrically actuated contact head and a can-shaped throwing agent container arranged thereon and closed with a lid. When the throwing body is fired, in addition to igniting and distributing the combustible leaflets that may be located in it, a pressing body is also ignited and disassembled via an ignition disassembly unit, a wall of the Throwing agent container is disassembled. The flammable pellets falling to the ground draw a mist curtain, which they nourish by burning them off from the ground.

In der DE 10 2011 100 2243 A1 wird ein Wirkmassenbehälter mit einem Deckel und wenigstens einer Ausblasöffnung sowie einer im Wirkmassenbehälter eingebundenen Wirkmasse vorgestellt. Der Deckel umfasst Rippen zur Versteifung des Wirkmassenbehälters. Der Deckel und die Rippen können dabei eine konstruktive Einheit bilden. Die Rippen können ihrerseits je nach Belastung vom Mittelrohr bis an die Außenkante des Wirkmassenbehälters verlaufen.In the DE 10 2011 100 2243 A1 an active mass container with a lid and at least one blow-out opening and an active mass incorporated in the active mass container is presented. The lid includes ribs to stiffen the active substance container. The lid and the ribs can form a structural unit. Depending on the load, the ribs can in turn run from the center tube to the outer edge of the active substance container.

Verwendbare Nebelkörper beschreiben beispielsweise die DE 10 2008 019 752 A1 sowie die DE 103 08 307 B4 . Die Nebelsubmunition der DE 103 08 307 B4 weist eine Submunitionskörperhülle aus Stahl auf, in deren Innerem sich eine Wirkmasse befindet. Die Submunitionskörperhülle ist in Schussrichtung mit einem Deckel versehen. In diesem befindet sich ein Ausblasloch, aus dem der Nebel nach Anzündung der Wirkmasse austreten kann. Auch die DE 10 2008 019 752 A1 zeigt eine Submunition mit Wirkmassen, wie pyrotechnische Nebel, wobei der Wirkkörperbehälter durch einen Deckel mit Ausblasöffnung verschlossen ist.Usable fog bodies describe, for example DE 10 2008 019 752 A1 as well as the DE 103 08 307 B4 . The fog submunition of the DE 103 08 307 B4 has a submunition shell made of steel, inside of which there is an active mass. The submunition shell is provided with a cover in the firing direction. In this there is a blow-out hole from which the fog can emerge after the active mass has been ignited. Also the DE 10 2008 019 752 A1 shows a submunition with active masses, such as pyrotechnic fog, the active substance container being closed by a cover with a blow-out opening.

Aus fertigungstechnischen Gründen sowie aufgrund der hohen Belastung beim Abschuss der Geschosse, sind die Nebelkörper in den Geschossen so montiert, dass die Ausblasöffnungen in Flugrichtung weisen. Nach dem Abschuss aus dem Geschoss fliegen die Nebelkörper in dieser Ausrichtung bzw. Lage weiter. Das kann dazu führen, dass beim Aufprall auf den Boden die Nebelkörper erlöschen könnten. Nicht auszuschließen ist diese Situation, wenn nasser Boden oder Schnee in größeren Mengen in die Ausblasöffnung(en) eindringt.For manufacturing reasons and due to the high load when the projectiles are fired, the fog bodies are mounted in the storeys so that the exhaust openings point in the direction of flight. After being fired from the projectile, the smoke bodies continue to fly in this orientation. This can lead to the fog bodies being extinguished if they hit the ground. This situation cannot be ruled out if large amounts of wet ground or snow penetrate the discharge opening (s).

Teilweise werden die Nebelkörper mit Fallschirmen oder Bremstüchern versehen, um die Aufprallgeschwindigkeit zu reduzieren, wie beispielsweise in der DE 196 02 422 C1 angedacht.In some cases, the fog bodies are provided with parachutes or brake pads to reduce the speed of impact, such as in the DE 196 02 422 C1 contemplated.

Da nicht immer verhindert werden kann, dass diese insbesondere textilen Bremstücher oder Fallschirme beschädigt werden können, und zudem der Montageaufwand ein sehr hoher ist, stellt sich die Erfindung die Aufgabe, eine andere Möglichkeit zur Erhöhung der Zuverlässigkeit von Nebelkörpern bei Minimierung des Montageaufwandes aufzuzeigen.Since it is not always possible to prevent these, in particular textile brake pads or parachutes, from being damaged, and moreover, the assembly effort is very high, the object of the invention is to show another possibility for increasing the reliability of fog bodies while minimizing the assembly effort.

Gelöst wird die Aufgabe in alternativer Weise durch die Merkmale der beiden unabhängigen Ansprüche 1 und 2. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.The object is achieved in an alternative manner by the features of the two independent claims 1 and 2. Advantageous refinements can be found in the subclaims.

Der Erfindung liegt die Idee zugrunde, die Erhöhung der Zuverlässigkeit durch einen zusätzlichen Schutz des / der Ausblasöffnung/en im Nebelkörperoberteil zu realisieren.The invention is based on the idea of realizing the increase in reliability by additional protection of the blow-out opening (s) in the upper part of the mist body.

Der Nebelkörper besteht aus einer Nebelkörperhülle, die von oben mittels eines Deckels mit wenigstens einer Ausblasöffnung verschlossen ist und bodenseitig einen Nebelkörperboden aufweist. In der Nebelkörperhülle eingebracht ist eine Nebelmasse.The mist body consists of a mist body shell, which is closed from above by means of a cover with at least one blow-out opening and has a mist body floor on the bottom side. A fog mass is introduced into the mist body shell.

Nunmehr ist erfindungsgemäß vorgesehen, oberhalb des Deckels mit der wenigstens einen Ausblasöffnung einen Aufsatz anzubringen, der die Ausblasöffnung selbst schützt, bzw. den Deckel selbst in dieser Art und Weise auszuführen. Eine Alternative hierzu besteht darin, die wenigstens eine Ausblasöffnung mit einer Klappe zu versehen, die unter dem Druck des sich aufbauenden Nebels diesen entweichen lassen. In beiden Ausführungen wird erreicht, dass keine Fremdkörper, wie Schmutz, Dreck oder dergleichen, in die wenigstens eine Ausblasöffnung eintreten kann. Damit wird verhindert, dass der Nebelkörper beim Auftreffen auf den Boden erlischt. Durch den Einsatz eines Deckels, der die wenigstens eine Ausblasöffnung abdeckt und die entstehenden Gase zur Seite oder über wenigstens eine Klappe ausbläst, wird auf einfache Art und Weise ein Eindringen von Schmutz etc. beim Aufprall des Nebelkörpers auf den Boden verhindert. Es versteht sich, dass auch eine Kombination beider Varianten möglich ist.It is now provided according to the invention to mount an attachment above the lid with the at least one blow-out opening, which protects the blow-out opening itself, or to design the lid itself in this way. An alternative to this is to provide the at least one blow-out opening with a flap which can be released under the pressure of the mist which is building up. In both versions it is achieved that no foreign bodies, such as dirt, dirt or the like, can enter the at least one blow-out opening. This prevents the fog body from going out when it hits the ground. The use of a cover, which covers the at least one blow-out opening and blows out the resulting gases to the side or via at least one flap, prevents dirt, etc. from penetrating in a simple manner when the mist body hits the floor. It goes without saying that a combination of both variants is also possible.

Dadurch kann der Einsatzbereich der Nebelkörper erweitert werden und ist nicht mehr umgebungsabhängig, da auch bei sehr nassen Böden und / oder Schnee eine Funktion gewährleistet werden kann. Zudem ist der Materialaufwand zur Realisierung gering, der Montageaufwand ist minimal. Da der prinzipielle Aufbau des Nebelkörpers selbst, wie auch die Anordnung der Nebelkörper im Geschoss erhalten bleiben, muss auch das Fertigungsverfahren nicht verändert werden. Die vorhandenen Betriebsmittel können weiter verwendet werden.As a result, the area of application of the fog bodies can be expanded and is no longer dependent on the environment, since a function can be guaranteed even on very wet floors and / or snow. In addition, the material required for implementation is low, the assembly effort is minimal. Since the basic structure of the smoke body itself, as well as the arrangement of the smoke body on the floor, are retained, the manufacturing process does not have to be changed. The existing equipment can continue to be used.

Vorgeschlagen wird ein Nebelkörper mit einer Nebelkörperhülle und einer darin eingebetteten Nebelmasse, einem Nebelkörperboden sowie einer Nebelkörperoberseite, wobei der Nebelkörper in seiner Nebelkörperoberseite zumindest eine Ausblasöffnung aufweist. Um zu vermeiden, dass beim Auftreffen des Nebelkörpers im Zielgebiet die wenigstens eine Ausblasöffnung mit Schmutz, Staub, Dreck, Boden etc. zugesetzt wird, befindet sich an der Nebelkörperbodenseite ein Aufsatz, der über Abstützungen, wenigstens zwei, von der Nebelkörperoberseite beabstandet ist. Alternativ oder zusätzlich kann die wenigstens eine Ausblasöffnung durch eine Klappe verschlossen sein, die dann, wenn sich im Nebelkörper ein ausreichender Gasdruck eingestellt hat, die wenigstens eine Ausblasöffnung freigibt. Bei mehreren Ausblasöffnungen kann für jede eine eigene Klappe vorgesehen werden.A mist body with a mist body shell and a mist mass embedded therein, a mist body bottom and a top of the mist body is proposed, the mist body having at least one blow-out opening in its top of the mist body. To avoid the at least one blow-out opening when the fog body hits the target area with dirt, dust, dirt, soil etc. is added, there is an attachment on the fog body bottom side, which is spaced from the upper side of the fog body via supports, at least two. Alternatively or additionally, the at least one blow-out opening can be closed by a flap which, when a sufficient gas pressure has set in the mist body, releases the at least one blow-out opening. If there are several exhaust openings, a separate flap can be provided for each.

Anhand eines Ausführungsbeispiels mit Zeichnung soll die Erfindung näher erläutert werden.The invention will be explained in more detail using an exemplary embodiment with a drawing.

Es zeigt:

Fig. 1
eine erste Variante einen Schutz wenigstens einer Ausblasöffnung eines Nebelköpers,
Fig. 2
eine weitere Variante den Schutz wenigstens einer Ausblasöffnung des Nebelkörpers.
It shows:
Fig. 1
a first variant of protecting at least one outlet opening of a fog body,
Fig. 2
a further variant the protection of at least one blow-out opening of the mist body.

In Fig. 1 dargestellt ist skizzenartig ein Nebelkörper 1 mit einer Nebelkörperhülle 2, einer Nebelkörperoberseite 3 und einem Nebelkörperboden 4. Der Nebelkörper 1 beinhaltet eine Nebelmasse 5 zur Erzeugung eines Nebels.In Fig. 1 a sketch of a mist body 1 with a mist body shell 2, a mist body top 3 and a mist body bottom 4 is shown. The mist body 1 contains a mist mass 5 for generating a mist.

An seiner Oberseite 3 besitzt der Nebelkörper 1 zumindest eine Ausblasöffnung 6, bevorzugt jedoch mehrere, durch die der Nebel aus dem Nebelkörper 1 austreten kann. Diese wenigsten eine Ausblasöffnung 6 kann in einem die Oberseite 3 abdeckenden Deckel 3' eingebracht sein.On its upper side 3, the fog body 1 has at least one blow-out opening 6, but preferably several, through which the fog can emerge from the fog body 1. This at least one blow-out opening 6 can be introduced in a cover 3 'covering the upper side 3.

Erfindungsgemäß ist nun vorgesehen, auf dieser Oberseite 3 bzw. auf den Deckel 3' einen Aufsatz 7 aufzubringen, der von der Oberseite 3 bzw. dem Deckel 3' beabstandet ist. Dazu sind am Aufsatz 7 Abstützungen 8 befestigt. Diese können einteilig mit dem Aufsatz 7 ausgeführt sein. Die Abstützungen 8 können aber auch am Deckel 3' oder an der Oberseite 3 angebracht und Bestandteil dieser sein, ggf. auch einteilig. Schlägt der Nebelkörper 1 auf dem Boden auf, wird die wenigstens eine Ausblasöffnung 6 durch den Aufsatz 7 vom Boden beabstandet. Der sich aufbauende Nebel tritt aus der / den Ausblasöffnung/en und danach seitlich aus dem Nebelkörper 1 aus.According to the invention, an attachment 7 is now provided on this upper side 3 or on the lid 3 ', which is spaced apart from the upper side 3 or the lid 3'. For this purpose, supports 8 are attached to the attachment 7. These can be made in one piece with the attachment 7. The supports 8 can also be attached to the lid 3 'or on the top 3 and be part of this, if necessary also in one piece. If the mist body 1 hits the floor, the at least one blow-out opening 6 is spaced apart from the floor by the attachment 7. The mist that builds up emerges from the outlet opening (s) and then laterally out of the mist body 1.

Eine Alternative zeigt die Fig. 2. Die wenigstens eine Ausblasöffnung 6 ist hier durch eine dieser zugeordneten Klappe 9 verschlossen. Ähnlich eines Rückschlagventils gibt die Klappe 9 die Ausblasöffnung 6 dann frei, wenn sich ein bestimmter Gasdruck im Inneren der Nebelkörperhülle 2 nach Zünden der Nebelmasse 5 aufgebaut hat. Mit Öffnen der Klappe/n 9 strömt der Nebel aus dem Nebelkörper 1 heraus. Die Klappe/n 9 übernehmen den Schutz der Ausblasöffnung/en 6 beim Aufprall des Nebelkörpers 1 auf den Boden und drücken beim Öffnen Schmutz, Dreck Schnee etc. weg.An alternative shows that Fig. 2 . The at least one blow-out opening 6 is closed here by a flap 9 assigned to it. Similar to a check valve, the flap 9 opens the blow-out opening 6 when a certain gas pressure has built up inside the mist body shell 2 after the mist mass 5 has been ignited. When the flap (s) 9 are opened, the mist flows out of the mist body 1. The flap (s) 9 protect the blow-out opening (s) 6 when the mist body 1 strikes the floor and push dirt, dirt snow, etc. away when opened.
