Description

Bei Tragholmen für Flugzeuge ist es bekannt, etwa halbkreisförmige Schalen zu verwenden. It is known to use approximately semicircular shells in support struts for aircraft.

Erfindungsgemäß läßt man die etwa halb· kreisförmigen Schalen unmittelbar aneinanderstoßen. Man überlascht sie an den Stoßkanten durch Deckschienen. Hierdurch erhält man eine außerordentlich feste Verbindung des gebauten Holmes. Die Festigkeit wird noch, um ein wesentliches erhöht, wenn man die Stoßkanten und die Deckschiene oben und unten am Tragholm vorsieht, da hierdurch der Holm gerade in den auf Biegung am stärksten beanspruchten Zonen ver stärkt wird.According to the invention, the approximately semicircular shells are allowed to directly abut one another. They are covered by cover rails at the abutting edges. This creates an extremely strong connection of the built Holmes. The strength is still increased by a substantial, though the abutting edges and the cover rail are provided at the top and bottom of the support beam, there as a result, the spar verifies in the areas that are most exposed to bending is strengthened.

Der Tragholm setzt sich aus etwa halbkreisförmigen Schalend zusammen; die Längskanten der Schalen sind durch die D eckschienen e überlascht. Hierdurch wird nicht nur die Verbindung im Holm äußerst fest, sondern es wird vor allen Dingen der Hohn in den am stärksten beanspruchten Zonen nicht unwesentlich versteift.tapering spar / z is firmly connected to the ribs b of the wing with the flanges c , for example riveted or welded. The support spar is composed of approximately semicircular shells; the longitudinal edges of the shells are überlascht by the corner rails D e. This not only makes the connection in the spar extremely strong, but above all the mockery in the most stressed areas is not insignificantly stiffened.
