Description

Vorrichtung zur beschußsicheren Abdeckung von der Be- und Entlüftung dienenden Lufteis und Austrittsöffnungen bei Panzerfahrzeugen Die Erfindung betrifft eine Vorrichtung zur beschußsicheren Abdeckung von der Be- und Entlüftung dienenden Luftein-und-austrittsöffnungen bei Panzerfahrzeugen in Form von quer zur Luftdurchgangsrichtung und parallel zueinander angeordneten im Querschnitt etwa S-förmigen Profilstäben (Grätings).Device for bulletproof covering of the ventilation serving air ice and outlet openings in armored vehicles The invention relates a device for the bulletproof cover of the ventilation serving Air inlet and outlet openings in armored vehicles in the form of transverse to the air passage direction and parallel to each other arranged in cross-section approximately S-shaped profile rods (Grätings).

Diese Grätings sind aus Profilstäben gebildete Metallgitter, die der Abdeckung von Lufteintritts-und -austrittsöffnungen gegen Beschuß dienen, d. h., sie sollen den Durchtritt von Geschossen oder Sprengstücken auf geradlinigem Wege verhindern. Weiterhin wird an diese Grätings die Forderung gestellt, dem Luftdurchtritt einen möglichst geringen Strömungswiderstand entgegenzustellen. Außerdem sollen die Grätings möglichst leicht sein.These gratings are metal grids formed from profile bars, which the Covering air inlet and outlet openings to protect against bombardment, d. H., they are intended to allow projectiles or explosives to pass through in a straight line impede. Furthermore, the requirement is placed on these grating, the passage of air to oppose the lowest possible flow resistance. Also should the gratings should be as light as possible.

Es sind die verschiedensten Arten von Grätings bekanntgeworden, aber entweder sind sie aus dünnen Profilstäben gebildet und dienen einem möglichst günstigen Luftdurchtritt oder es sind schwere Gitterstäbe angeordnet, um Geschosse oder Sprengstücke abzufangen. Die erste Art der Grätings, wie sie bei normalen Abdeckungen von Ventilatoren verwendet wird, ist nicht beschußsicher, und die zweite Art bildet normalerweise derart viel Lufttaschen bzw. scharfe Umlenkkanten, daß dadurch der Luftwiderstand unnötig erhöht wird.The most varied types of gratings have become known, but Either they are made of thin profile rods and serve as cheap as possible Air passage or heavy bars are arranged around projectiles or explosives intercept. The first type of grating, as found in normal fan covers is not bulletproof, and the second type usually forms so many air pockets or sharp deflection edges that this reduces air resistance is increased unnecessarily.

Durch die Erfindung werden die oben beschriebenen Mängel behoben, indem das S-förmige Querschnittsprofil der einzelnen Stäbe im Mittelbereich so weit verdickt ist, daß die zwischen den einzelnen Stäben verbleibenden Luftdurchlaßspalte sich nach der Innen- und/oder Außenseite hin erweitern. Unter den Schutz soll jedoch nicht die reine Abrundung der einzelnen Grätingsstäbe an ihren äußeren Enden fallen.The invention eliminates the deficiencies described above, by the S-shaped cross-sectional profile of the individual rods in the central area so far is thickened that the remaining air passage gaps between the individual rods expand towards the inside and / or outside. Under the protection should however not the pure rounding of the individual grating bars at their outer ends.

Mit besonderem Vorteil wird das S-förmige Querschnittsprofil der einzelnen, das Gräting bildenden Stäbe an den Enden in Richtung einer Normalen zur Innen- oder Außenfläche des ganzen Grätings abgebogen.The S-shaped cross-sectional profile of the individual, the grating forming rods at the ends in the direction of a normal to the inner or Curved outer surface of the whole grating.

Ein Teil eines Mittelschnittes durch ein solches Gräting, bestehend aus vier der das Gräting bildenden Profilstäbe, ist in der Zeichnung wiedergegeben, wobei durch Pfeile die Durchgangsrichtung der Luft angedeutet ist. Selbstverständlich richtet sich die Anzahl der das Gräting bildenden Stäbe nach der Größe der abzudeckenden Öffnung.Part of a central section through such a grating, consisting from four of the profile bars forming the grating, is shown in the drawing, the direction of passage of the air being indicated by arrows. Of course the number of bars forming the grating depends on the size of the bars to be covered Opening.
