Description
Kupplung der Tragflächenholme. Beim Bau von Flugzeugflächen ist man dazu übergegangen, Seitenstreben und Spanndrähte zwischen den oberen und unteren Tragflächen nach Möglichkeit. fortzulassen und dafür die Festigkeit des Flugzeuges durch Verstärkung der in dem Flächenprofil untergebrachten Tragholme zu gewährleisten. Auf diese Weise entstehen Holme, die in. der Bauhöhe sehr hoch sind. Die Holme bestehen im wesentlichen aus einem oberen und unteren Gurt.Coupling of the wing spars. When building aircraft surfaces, you are moved on to side struts and tension wires between the upper and lower Wings if possible. and the strength of the aircraft by reinforcing the support bars accommodated in the surface profile. This creates spars that are very high in height. The spars exist essentially consisting of an upper and lower belt.
Beide Gurte sind durch Wände miteinander verbunden, so daß die Holme kastenförmigen, doppel-T-förmigen oder einen ähnlichen Querschnitt erhalten.Both straps are connected by walls so that the spars box-shaped, double-T-shaped or a similar cross-section.
Schwierigkeiten entstehen nun, derartige Holme miteinander zu verbinden, und zwar derart, daß die Verbindungsstelle die gleiche Festigkeit besitzt wie der Holm selbst. Nach der Erfindung wird dies dadurch erreicht, daß die Holme in kammartig ausgebildete Endstücke auslaufen, welche durch einen auf Abscheren beanspruchten Bolzen miteinander gekuppelt werden. Die - kammartig ausgebildeten Endstücke werden vorteilhaft an den Gurten angenietet. Um fernerhin die Gurte vor zusätzlichen Biegungsbeanspruchungen zu schützen, wird die Mittellinie des Bolzens in die Schwerlinie des Gurtes verlegt. Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung bei Tragholmen von kastenförmigem Querschnitt in Fig. i in Seitenansicht, in Fig. 2 im Querschnitt und in Fig. 3 im Grundriß.Difficulties arise now to connect such spars with each other, in such a way that the joint has the same strength as the Holm itself. According to the invention, this is achieved in that the spars in a comb-like trained end pieces run out, which stressed by a shear Bolts are coupled together. The - comb-shaped end pieces are advantageously riveted to the straps. In order to further protect the belts from additional bending stresses To protect, the center line of the bolt is relocated to the center line of the belt. The drawing shows an embodiment of the invention with support bars of box-shaped Cross section in Fig. I in side view, in Fig. 2 in cross section and in Fig. 3 in Layout.
Die Tragflächenholme a und a1 bestehen aus den oberen Gurten b, b1 und den unteren Gurten b2, b3, welche durch die Seitenwände c, cl miteinander verbunden sind. An die Gurte b, b1 bzw. b,=, b3 sind paarweise kammartige Endstücke d, dl bzw. d2, d3 angenietet, welche durch je einen Bolzen g bzw. g1 zusammengekuppelt sind. Von besonderem Wert ist es, die Mittellinie des Bolzens g bzw. g1 in die Schwerlinien a:, y zu legen, wodurch die Gurte vor zusätzlichen Biegungsbeanspruchungen gesichert werden.The wing spars a and a1 consist of the upper straps b, b1 and the lower straps b2, b3, which are connected to one another by the side walls c, cl. Comb-like end pieces d, dl or d2, d3 are riveted to the belts b, b1 or b, =, b3 in pairs, which are each coupled together by a bolt g or g1. It is particularly important to place the center line of the bolt g or g1 in the median lines a :, y , so that the belts are secured against additional bending stresses.
