Description

Die Erfindung betrifft ein Geschoßsimulationsmittel gemäß dem Oberbegriff des Anspruchs 1 und 2. Des weiteren betrifft die Erfindung ein Verfahren zur Herstellung eines Geschoßsimulationsmittels gemäß dem Oberbegriff des Anspruchs 7.The invention relates to a projectile simulation means according to the The preamble of claims 1 and 2. Furthermore relates to Invention a method for producing a Missile simulation means according to the preamble of Claim 7.

Geschoßsimulationsmittel dienen vornehmlich zur Simulation einer akustischen und/oder optischen Darstellung des Abschusses von Kanonen oder dergleichen, insbesondere Panzerkanonen.Projectile simulation means are primarily used to simulate a acoustic and / or visual representation of the launch of cannons or the like, in particular tank cannons.

Derartige Geschoßsimulationsmittel müssen verschiedene Anforderungen erfüllen. Erstens müssen sie deutlich wahrnehmbar sein, insbesondere durch einen lauten Knall. Zweitens dürfen die durch eine Explosion entstehenden Splitterteile einen bestimmten Sicherheitsbereich nicht verlassen. Such projectile simulation means have different requirements fulfill. First, they must be clearly noticeable especially by a loud bang. Second, they can a certain piece of fragments created by an explosion Do not leave the security area.

Aus der US-A-5 138 948 (Basis für den Oberbegriff der Ansprüche 1, 2 und 7) ist ein Geschoßsimulationsmittel bekannt, das eine zweiteilige Umhüllung mit einem darin angeordneten Effektsatz aufweist. Die Teile der Umhüllung sind durch Reibschweißung fest miteinander verbunden. Durch die Zündung des Effektsatzes wird die Umhüllung getrennt. Da die Reibschweißung der Teile der Umhüllung nicht so ausführbar ist, daß die Umhüllung an der Schweißnaht aufreißt, kann bei der Zündung des Effektsatzes die Umhüllung an einer beliebigen Stelle aufplatzen. Das führt zu einem unkontrollierten Zersplittern der Umhüllung, was die Sicherheit des bekannten Geschoßsimulationsmittels beeinträchtigt.A projectile simulation means is known from US-A-5 138 948 (basis for the preamble of claims 1, 2 and 7), which is a two-part casing with one arranged in it Has effect set. The parts of the wrapper are through Friction welding firmly connected. Through the ignition the wrapping is separated from the effect set. Since the Friction welding of the parts of the casing is not so feasible, that the covering tears open at the weld seam, can Ignition of the effect set wrapping on any Burst open. This leads to an uncontrolled fragmentation the casing, which is the safety of the known projectile simulation means impaired.

Aus der FR-A-2 022 758 ist ein weiteres Geschoßsimulationsmittel bekannt, bei dem ein Effektsatz in einer Umhüllung aus einem beidseitig durch einen Stopfen verschlossenen Rohr und einem zusätzlichen Gehäuse zur Aufnahme der Umhüllung mit dem Effektsatz gebildet ist. Das Gehäuse weist am Boden eine Sollbruchstelle auf. Dadurch kann ein Teil des Bodens vom Gehäuse abgetrennt werden. Der abgetrennte Teil des Bodens und die das Rohr der Umhüllung verschließenden Stopfen bilden eine zusätzliche Gefahr beim Zünden des Geschoßsimulationsmittels. Das gilt insbesondere für die großvolumigen Stopfen, die beim Zünden des Geschoßsimulationsmittel nicht zerstört werden.FR-A-2 022 758 is a further projectile simulation means known in which an effect set in an envelope from a tube sealed on both sides by a stopper and an additional housing to accommodate the casing with the Effect set is formed. The case has a bottom Predetermined breaking point. This allows part of the floor to Housing be separated. The separated part of the soil and the plugs closing the tube of the casing form one additional danger when igniting the projectile simulation means. This applies in particular to the large-volume plugs that are used for Ignition of the projectile simulation means cannot be destroyed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein sicher und einfach aufgebautes Geschoßsimulationsmittel sowie ein Verfahren zur kostengünstigen Herstellung desselben zu schaffen.The present invention has for its object a safe and simply constructed projectile simulation means as well as a To create methods for inexpensive manufacture of the same.

Zwei eigenständige Geschoßsimulationsmittel zur Lösung dieser Aufgabe weisen die Merkmale des Anspruchs 1 einerseits und des Anspruchs 2 andererseits auf. Durch die Anordnung des Effektsatzes in einer Umhüllung aus durch Reibschweißung miteinander verbundenen Teilen und Sollbruchstellen entsteht ein sicheres und einfach aufgebautes Geschoßsimulationsmittel. Durch die Sollbruchstellen der Umhüllung wird verhindert, daß diese im Moment der Explosion unkontrolliert zersplittert und Splitterteile aus dem Sicherheitsbereich (von üblicherweise 50m) herausgeschleudert werden. Die durch die Sollbruchstellen geschwächten Teile der Umhüllung, insbesondere Aufnahmeraumdecke und -boden, reißen an der dafür vorgesehenen Seite und klappen scharnierartig auf, und zwar ohne sich von der Umhüllung zu lösen.Two independent projectile simulation tools to solve this Task have the features of claim 1 on the one hand and the Claim 2 on the other hand. By arranging the Effect set in an envelope made by friction welding interconnected parts and predetermined breaking points a safe and simply constructed projectile simulation tool. The predetermined breaking points of the casing prevent these shattered uncontrollably at the moment of the explosion and Splinter parts from the security area (from usual 50m) are thrown out. The through the predetermined breaking points weakened parts of the envelope, in particular the recording room ceiling and floor, tear at the designated Side and fold open like a hinge, without coming off to release the wrapping.

In einer weiteren vorteilhaften Ausbildung des Geschoßsimulationsmittels beträgt die Wandstärke der Umhüllung 1,5 bis 3 mm, insbesondere ca. 2 mm. Dadurch wird eine ausreichende Dämmung erreicht.In a further advantageous embodiment of the projectile simulation means the wall thickness of the casing is 1.5 to 3 mm, in particular about 2 mm. This ensures adequate insulation reached.

Das erfindungsgemäße Verfahren zur Herstellung des Geschoßsimulationsmittels weist die Merkmale des Anspruchs 7 auf. Ein Effektsatz wird direkt in einen Aufnahmeraum eines Unterteils der Umhüllung eingebracht. Dies wird dadurch besonders vereinfacht, weil der Aufnahmeraum des Unterteils eine große Öffnung zum Befüllen aufweist, die erst nach dem Befüllen durch einen zweiten, oberen Teil (Deckel) der Umhüllung verschlossen wird. Beide Teile der Umhüllung werden durch Reibschweißung fest miteinander verbunden.The method according to the invention for producing the projectile simulation means has the features of claim 7. An effect set is directly in a recording room of a lower part of the Wrapping introduced. This is particularly simplified because the receiving space of the lower part has a large opening for filling has, which only after filling by a second, the upper part (lid) of the wrapper is closed. Both parts of the casing are firmly joined together by friction welding connected.

Durch den erfindungsgemäßen einfachen Aufbau des Geschoßsimulationsmittels und der Tatsache, daß die Umhüllung vorteilhafterweise nur aus zwei Teilen besteht, ist eine einfache und kostengünstige Herstellung gewährleistet.Due to the simple structure of the projectile simulation means according to the invention and the fact that the wrapping is advantageous consists of only two parts, is a simple and inexpensive Manufacturing guaranteed.

Nach dem Verbinden beider Teile durch Reibschweißung entsteht ein geschlossener Aufnahmeraum 18 in einem Teilbereich der Umhüllung 11. In dem Aufnahmeraum 18 ist ein Effektsatz 19 angeordnet. Durch eine Öffnung 20 im Deckelboden 15 ragt eine Zündpille 21 in den Aufnahmeraum 18. An die Zündpille 21 sind zwei Zündkabel 22 angeschlossen, die aus der Öffnung 20 herausführen und am äußeren Ende mit einem Stecker 23 verbunden sind. Der Aufnahmeraum 18 wird im Bereich der Öffnung 20 des Deckelbodens 15 durch ein Dichtungselement 24 feuchtigkeitsdichtend geschlossen. Zum Schutz des gesamten Zündelements 25 vor Beschädigungen oder dergleichen wird auf den Deckel 13 eine dünnwandige Schutzkappe 26 gesteckt.After connecting both parts by friction welding a closed receiving space 18 in a partial area of the Envelope 11. In the receiving space 18 there is an effect set 19 arranged. One protrudes through an opening 20 in the lid base 15 Primer 21 in the receiving space 18. At the primer 21 are two ignition cables 22 connected from the opening 20th lead out and connected at the outer end with a plug 23 are. The receiving space 18 is in the region of the opening 20 of the Lid base 15 moisture-sealing by a sealing element 24 closed. To protect the entire ignition element 25 before damage or the like is on the lid 13th a thin-walled protective cap 26 is inserted.

Der Effektsatz 19 befindet sich unmittelbar in der einwandigen Umhüllung 11. Die Umhüllung 11 weist eine solche Wandstärke auf, daß eine ausreichende Dämmung gewährleistet ist. Gleichzeitig schützt die Umhüllung 11 den Aufnahmeraum 18 mit dem darin befindlichen Effektsatz 19 vor Feuchtigkeitseinflüssen.The effect set 19 is located directly in the single-walled Covering 11. The covering 11 has such a wall thickness that adequate insulation is guaranteed. At the same time protects the envelope 11 the receiving space 18 with the therein effect set 19 against the effects of moisture.

Der Deckelboden 15 liegt an einem oberen Rand der Außenhülse 12 an. Die Mantelfläche 14 des Deckels 13 unterhalb des Deckelbodens 15 überlappt einen Teilbereich der Mantelfläche 16 der Außenhülse 12 oberhalb des Außenhülsenbodens 17. Der Deckel 13 und die Außenhülse 12 bilden im Überlappungsbereich eine Nahtstelle 28.The receiving space 18 is through the lid base 15, the outer sleeve bottom 17 and one lying above the outer sleeve base 17 inner lateral surface 27 of the outer sleeve 12 is formed. The lid bottom 15 abuts an upper edge of the outer sleeve 12. The The lateral surface 14 of the cover 13 below the cover base 15 overlaps a partial area of the outer surface 16 of the outer sleeve 12 above the outer sleeve bottom 17. The lid 13 and the Outer sleeve 12 form a seam 28 in the overlap area.

Der Innendurchmesser des Deckels 13 ist geringfügig kleiner als der Außendurchmesser der Außenhülse 12, so daß die beiden Teile im zusammengesteckten Zustand einen Preßsitz aufweisen. Durch Reibschweißung werden die beiden Teile, nämlich die Außenhülse 12 und der Deckel 13, im Überlappungsbereich fest miteinander verbunden. The inside diameter of the cover 13 is slightly smaller than the outer diameter of the outer sleeve 12 so that the two parts have an interference fit in the assembled state. By The two parts, namely the outer sleeve, are friction welded 12 and the lid 13, firmly together in the overlap area connected.
