Description

Die Erfindung betrifft ein gepanzertes Fahrzeug, insbesondere ein Kampffahrzeug, bei welchem in einer Außenwand eine Lufteintrittsöffnung angeordnet ist, hinter der im Fahrzeuginneren ein Kühler positioniert ist, wobei die Lufteintrittsöffnung mit einer ballistischen Schutzeinrichtung versehen ist.The invention relates to an armored vehicle, in particular a combat vehicle, in which an air inlet opening is arranged in an outer wall, behind which a radiator is positioned in the vehicle interior, wherein the air inlet opening is provided with a ballistic protection device.

Bei bekannten gepanzerten Fahrzeugen sind die ballistischen Schutzeinrichtungen an der Lufteintrittsöffnung im allgemeinen als sogenannte Grätings ausgebildet, was den Nachteil hat, daß die ballistischen Wirkungen richtungsabhängig sind und die Radarsignaturen auffällig sind. Es ist auch bekannt, über den Lufteintrittsöffnungen jeweils eine Abdeckplatte anzuordnen, wobei die Luft seitlich unter der Abdeckplatte hindurch eintritt, was den Nachteil hat, daß die Fahrzeugdächer erhöht werden müssen. Derartige Anordnungen sind aus DE 1114410 und DE 4228 865 bekannt.In known armored vehicles, the ballistic guards at the air inlet opening are generally designed as so-called Grätings, which has the disadvantage that the ballistic effects are direction-dependent and the radar signatures are conspicuous. It is also known, in each case to arrange a cover plate over the air inlet openings, wherein the air enters laterally under the cover plate, which has the disadvantage that the vehicle roofs must be increased. Such arrangements are made DE 1114410 and DE 4228 865 known.

Der Erfindung liegt die Aufgabe zugrunde, ein gepanzertes Fahrzeug, insbesondere ein Kampffahrzeug mit den eingangs und im Oberbegriff des Patentanspruchs 1 beschriebenen Merkmalen so auszubilden, daß einerseits ein ausreichender Luftzutritt sichergestellt ist, andererseits aber ein hoher ballistischer Schutz und eine niedrige Radar- und IR-Signatur erreicht werden können.The invention has the object of providing an armored vehicle, in particular a combat vehicle with the features described in the preamble of claim 1 in such a way that on the one hand sufficient air access is ensured, on the other hand, a high ballistic protection and a low radar and IR Signature can be achieved.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, dass im Fahrzeuginneren im Bereich zwischen dem Kühler und der Lufteintrittsöffnung eine im wesentlichen parallel zur Außenwand verlaufende Bodenplatte angeordnet ist, deren Außendimensionen gleich oder um einen vorgegebenen Betrag kleiner als die Dimensionen der Lufteintrittsöffnung sind, und die Zwischenräume zwischen den Außenkanten der Bodenplatte und den Innenkanten der Lufteintrittsöffnung durch einen geschlossenen Ring bildende Abdeckbleche verschlossen sind, und die Bodenplatte im mittleren Bereich eine Luftdurchtrittsöffnung aufweist, unter welcher der Kühler positioniert ist, und die durch die Bodenplatte und die Abdeckbleche gebildete Vertiefung von einer Schutzplatte teilweise überdeckt ist, deren Dimensionen mindestens entlang von Teilbereichen ihrer Außenkanten kleiner sind als die Dimensionen der Lufteintrittsöffnung, aber größer als die Dimensionen der Luftdurchtrittsöffnung in der Bodenplatte, und die im wesentlichen in der Ebene der Außenwand angeordnet ist Vorteilhafte Weiterbildungen der Erfindung sind weiter unten und in den abhängigen Ansprüchen beschrieben.The solution of this object is achieved according to the invention, that in the vehicle interior in the region between the radiator and the air inlet opening a substantially parallel to the outer wall extending bottom plate is arranged, the outer dimensions are equal to or smaller by a predetermined amount than the dimensions of the air inlet opening, and the spaces between the outer edges of the bottom plate and the inner edges of the air inlet opening are closed by a closed ring forming cover plates, and the bottom plate in the central region has an air passage opening, under which the cooler is positioned, and partially covers the recess formed by the bottom plate and the cover plates of a protective plate is, whose dimensions are at least along partial areas of their outer edges smaller than the dimensions of the air inlet opening, but larger than the dimensions of the air passage opening in the bottom plate , and which is arranged substantially in the plane of the outer wall. Advantageous developments of the invention are described below and in the dependent claims.

Der Grundgedanke der Erfindung besteht darin, die Lufteintrittsöffnung bis auf mindestens zwei offene, den Lufteintritt zulassende Luftdurchtrittsschlitze mit einer Schutzplatte zu überdecken, die als Panzerplatte ausgebildet ist und im wesentlichen bündig und parallel mit der umgebenden Fahrzeugkontur angeordnet ist. Unterhalb dieser Schutzplatte ist eine Bodenplatte angeordnet, die im mittleren Bereich eine Luftdurchtrittsöffnung aufweist, unter welcher der Kühler positioniert ist. Da die Schutzplatte die Luftdurchtrittsögnung in der Bodenplatte überlappt, ist eine ballistische Dichtheit unter allen Bedrohungswinkeln sichergestellt. Ferner können zur abdeckenden Schutzplatte parallele Platten im Randbereich angeordnet werden, die gleichzeitig zur Herstellung einer über die Lufteintrittsöffnung ausgewogenen Strömungsverteilung verwendet werden. Der Raum unterhalb der abdeckenden Schutzplatte wird durch im wesentlichen senkrecht zur Schutzplatte stehende Trennwände so unterteilt, daß mindestens zwei den obengenannten Luftdurchtrittsschlitzen zugeordnete Volumen entstehen. Die Trennwände können an die abdeckende Schutzplatte angebunden sein und können entweder mit Spalt oder bündig zu den nachfolgenden Luftführungselementen angeordnet sein. Durch die Hinterlüftung der abdeckenden Schutzplatte kann eine niedrige IR-Signatur erreicht werden, während eine niedrige Radarsignatur sich aus der parallel zur umgebenden Fahrzeugstruktur angeordneten ebenen Schutzplatte ergibt, was durch radarabsorbierende Beschichtungen des Lufteintrittsbereiches sowie der Unterseite der abdeckenden Schutzplatte und der Trennwände noch verbessert werden kann.The basic idea of the invention is to cover the air inlet opening with at least two open, the air inlet permitting air passage slots with a protective plate, which is designed as an armor plate and is arranged substantially flush and parallel to the surrounding vehicle contour. Below this protective plate, a bottom plate is arranged, which has an air passage opening in the middle region, under which the cooler is positioned. Since the protective plate overlaps the Luftdurchtrittsögnung in the bottom plate, a ballistic tightness is ensured under all threat angles. Furthermore, parallel plates can be arranged in the edge region for covering protective plate, which are used simultaneously for producing a balanced over the air inlet flow distribution. The space below the covering protective plate is divided by partitions substantially perpendicular to the protective plate, that at least two of the above-mentioned air passage slots associated volume arise. The partitions can be connected to the covering protective plate and can be arranged either with gap or flush with the subsequent air guide elements. Due to the ventilation of the covering protective plate, a low IR signature can be achieved, while a low radar signature results from the plane parallel to the surrounding vehicle structure arranged flat protective plate, which can be improved by radar absorbing coatings of the air inlet region and the underside of the protective cover and the partition walls ,

Fig. 1 zeigt die Ausgangssituation bei einer Dachplatte eines im übrigen nicht dargestellten Kampffahrzeugs im Bereich einer Lufteintrittsöffnung. Die Dachplatte 1 besitzt eine rechteckige Öffnung 2, unter der in angedeuteter Weise ein Kühler 3 angeordnet ist. Die Öffnung 2 soll nun mit einer ballistisch wirkenden Schutzabdeckung verschlossen werden.Fig. 1 shows the initial situation in a roof panel of a combat vehicle, not shown in the rest in the region of an air inlet opening. The roof panel 1 has a rectangular opening 2, below which a radiator 3 is arranged in the manner indicated. The opening 2 should now be closed with a ballistic protective cover.

Hierzu ist, wie aus Fig. 2 zu entnehmen, im Fahrzeuginneren im Bereich zwischen dem Kühler 3 und der Lufteintrittsöffnung der Dachplatte 1 eine im wesentlichen parallel zur Dachplatte 1 verlaufende Bodenplatte 5 angeordnet, deren Außendimensionen geringfügig kleiner sind als die Dimensionen der Lufteintrittsöffnung 2. Zur Halterung der Bodenplatte 5 dienen Abdeckbleche 4.1, 4.2, 4.3 und 4.4, welche in die Zwischenräume zwischen den Außenkanten der Bodenplatte 5 und den Innenkanten der Lufteintrittsöffnung 2 eingesetzt sind und einen geschlossenen Ring bilden. Dabei verlaufen, wie Fig. 2 zu entnehmen, die Abdeckbleche 4.2 und 4.4 leicht schräg nach innen zum mittleren Bereich der Bodenplatte hin abfallend. In ihrem mittleren Bereich weist die Bodenplatte 5 eine rechteckige Luftdurchtrittsöffnung 6 auf, unter welcher der Kühler 3 positioniert ist. Durch die Abdeckbleche 4.1 bis 4.4 sind die Zwischenräume zwischen Bodenplatte 5 und Dachplatte 1 zum Fahrzeuginneren hin vollständig abgeschlossen.For this purpose, as shown in Fig. 2, in the vehicle interior in the area between the radiator 3 and the air inlet opening of the roof panel 1 a substantially parallel to the roof panel 1 extending bottom plate 5 is arranged, whose outer dimensions are slightly smaller than the dimensions of the air inlet opening 2. Zur Holder of the bottom plate 5 serve cover plates 4.1, 4.2, 4.3 and 4.4, which are inserted into the spaces between the outer edges of the bottom plate 5 and the inner edges of the air inlet opening 2 and form a closed ring. In this case, as shown in FIG. 2, the cover plates 4.2 and 4.4 are sloping slightly obliquely inwards towards the middle region of the base plate. In its middle region, the bottom plate 5 has a rectangular air passage opening 6, below which the cooler 3 is positioned. Through the cover plates 4.1 to 4.4, the spaces between the bottom plate 5 and roof panel 1 to the vehicle interior are completely completed.

Wie Fig. 3 zu entnehmen, ist nun die durch die Bodenplatte 5 und die Abdeckbleche 4.1 bis 4.4 gebildete Vertiefung in der Fahrzeugkontur von einer rechteckigen Schutzplatte 7 derart teilweise überdeckt, daß zwischen den Außenkanten der Schutzplatte 7 und den Innenkanten der Lufteintrittsöffnung 2 ein insgesamt ringförmiger Durchtrittsschlitz entsteht. Dabei ist die Schutzplatte 7 in der Ebene der Dachplatte 1 und parallel zu dieser angeordnet und so dimensioniert, daß sie die Luftdurchtrittsöffnung 6 in der Bodenplatte 5 vollständig überdeckt, so daß unter allen Bedrohungswinkeln eine ballistische Dichtheit gewährleistet ist. Der Luftzutritt kann von vier Seiten her durch den gebildeten Ringkanal erfolgen.As shown in FIG. 3, the depression formed in the vehicle contour by the base plate 5 and the cover plates 4.1 to 4.4 is now partially covered by a rectangular protective plate 7 such that an overall ring-shaped between the outer edges of the protective plate 7 and the inner edges of the air inlet opening 2 Passage slot is created. The protective plate 7 is arranged in the plane of the roof panel 1 and parallel to this and dimensioned so that it completely covers the air passage opening 6 in the bottom plate 5, so that a ballistic tightness is ensured under all threat angles. The air can enter from four sides through the formed annular channel.

In den Zwischenraum zwischen Bodenplatte 5 und Schutzplatte 7 können weitere Schutz- und Luftleitelemente eingebracht werden. Dies wird im folgenden näher erläutert.In the space between the bottom plate 5 and the protective plate 7 more protective and air guide elements can be introduced. This will be explained in more detail below.

In Fig. 4 ist dargestellt, wie der Raum zwischen Bodenplatte 5 und Schutzplatte 7 durch Luftleitbleche 8.1, 8.2 und 8.3 in mehrere voneinander getrennte Eintrittsbereiche für die zuströmende Luft aufgeteilt werden kann. Hierzu sind die Luftleitbleche 8.1 bis 8.3 in Aufsicht auf die Luftdurchtrittsöffnung 6 gesehen H-förmig angeordnet, wobei der Querbalken 8.3 des H im wesentlichen auf einer Mittellinie der Luftdurchtrittsöffnung 6 liegt und die beiden Längsbalken 8.1 und 8.2 des H in den Randbereichen der Luftdurchtrittsöffnung 6 verlaufen. Hierbei ist die Länge der beiden Längsbalken 8.1 und 8.2 größer als die Breite der Luftdurchtrittsöffnung 6. Wie Fig. 4 zu entnehmen, entstehen somit vier Luftzutrittsbereiche, in welche die Luft in Pfeilrichtungen A, B, C und D einströmt und zwar derart, daß keine Vermischung der aus vier Richtungen eintretenden Luftströmungen stattfindet und Wirbelbildungen und parasitäre Luftströmungen unterhalb der Schutzplatte 7 vermieden werden.In Fig. 4 shows how the space between the bottom plate 5 and the protective plate 7 can be divided by air baffles 8.1, 8.2 and 8.3 in several separate inlet regions for the incoming air. For this purpose, the baffles are 8.1 to 8.3 viewed in plan view of the air passage opening 6 H-shaped, wherein the cross bar 8.3 of H is located substantially on a center line of the air passage opening 6 and the two longitudinal beams 8.1 and 8.2 of the H in the edge regions of the air passage opening 6 , In this case, the length of the two longitudinal beams 8.1 and 8.2 is greater than the width of the air passage opening 6. As shown in FIG. 4, thus four Luftzutrittsbereiche, in which the air flows in arrow directions A, B, C and D in such a way that no Mixing occurring from four directions air flows takes place and vortex formations and parasitic air currents are avoided below the protective plate 7.

Selbstverständlich ist es auch möglich den Raum zwischen Bodenplatte und Schutzplatte durch etwas anders angeordnete Luftleitbleche in mehrere voneinander getrennte Eintrittsbereiche für die zuströmende Luft aufzuteilen. So können beispielsweise in Abweichung von der in Fig. 4 dargestellten Lage die Luftleitbleche in Aufsicht auf die Luftdurchtrittsöffnung gesehen auch T-förmig oder Y-förmig angeordnet sein. Wesentlich ist, daß getrennte Luftzutrittsbereiche entstehen, so daß keine Vermischung der aus unterschiedlichen Richtungen eintretenden Luftströmungen stattfindet.Of course, it is also possible to divide the space between the base plate and protective plate by slightly differently arranged air baffles in several separate inlet regions for the incoming air. For example, in deviation from the position shown in Fig. 4, the air baffles seen in plan view of the air passage opening can also be arranged T-shaped or Y-shaped. It is essential that separate air inlet areas arise, so that no mixing of the incoming air flows from different directions takes place.

Anhand von Fig. 5 ist erkennbar, daß weiterhin in dem Raum zwischen der Bodenplatte 5 und der in Fig. 5 genommenen Schutzplatte 7 eine Zwischenpanzerung 9 angeordnet sein kann, die in ihrem mittleren Bereich eine über der Luftdurchtrittsöffnung 6 liegende weitere Luftdurchtrittsöffnung aufweist und die sowohl zur Bodenplatte 5 als zur Schutzplatte 7 hin in einem gewissen Abstand angeordnet ist. Die Außendimensionen der Zwischenpanzerung 9 können gleich oder größer sein wie die Außendimensionen der Schutzplatte 7, wie dies aus Fig. 6 ersichtlich ist.5, it can be seen that, furthermore, an intermediate armor 9 can be arranged in the space between the bottom plate 5 and the protective plate 7 taken in FIG. 5, which has a further air passage opening lying above the air passage opening 6 in its central region and which both is arranged to the bottom plate 5 as the protective plate 7 out at a certain distance. The outer dimensions of the intermediate armor 9 may be equal to or greater than the outer dimensions of the protective plate 7, as shown in FIG. 6 can be seen.

Durch die Anordnung der Zwischenpanzerung 9 werden die Einströmwege der Luft noch einmal in vertikaler Richtung unterteilt, je nachdem, ob sich der Luftstrom oberhalb oder unterhalb der Zwischenpanzerung 9 bewegt. Wie aus Fig. 5 zu entnehmen, entstehen somit vier obere Luftströmungen A1, B1, C1 und D1 und vier untere Luftströmungen A2, B2, C2 und D2. Dabei werden die Teilluftströme A1 bis D1 zwischen der abdeckenden Schutzplatte 7 und der Zwischenpanzerung 9 in die inneren Bereiche der Luftdurchtrittsöffnung 6 geleitet, während die Teilluftströme A2 bis D2, die im Bereich zwischen der Zwischenpanzerung 9 und der Bodenpanzerung 5 verlaufen, in die äußeren Bereiche geleitet werden. Die Zwischenpanzerung 9 hat darüber hinaus die Aufgabe, die ballistischen Schwachstellen an den Rändern unter der abdeckenden Schutzplatte 7 zu schließen.The arrangement of the intermediate armor 9, the inflow of air are divided once again in the vertical direction, depending on whether the air flow above or below the intermediate armor 9 moves. As can be seen from FIG. 5, four upper air flows A1, B1, C1 and D1 and four lower air flows A2, B2, C2 and D2 thus arise. The partial air flows A1 to D1 between the covering protective plate 7 and the intermediate armor 9 are conducted into the inner regions of the air passage opening 6, while the partial air streams A2 to D2, which run in the region between the intermediate armor 9 and the bottom armor 5, are conducted into the outer regions become. The intermediate armor 9 also has the Task to close the ballistic weak points at the edges under the covering protective plate 7.

Fig. 6 zeigt die ballistisch dichte und aerodynamisch optimierte Lufteintrittsöffnung 2 in der umgebenden Fahrzeugpanzerung 1. Der Ringspalt zwischen Dachplatte 1 und Schutzplatte 7 kann mit einer luftdurchlässigen, Radarwirksamen Abdeckung abgedeckt werden oder die Abdeckbleche 4.1 bis 4.4 und die Unterseiten der abdeckenden Schutzplatte 7 sowie der Zwischenpanzerungen 9 können mit radarabsorbierenden Beschichtungen versehen werden.The annular gap between the roof panel 1 and the protective plate 7 can be covered with an air-permeable, Radar effective cover or the cover plates 4.1 to 4.4 and the undersides of the protective cover plate 7 and the Intermediate armor 9 can be provided with radar absorbing coatings.
