Description
flügel 3 am weitesten nach oben und der hinterste Teilflügel 6 am weitesten nach unten verschwenkt ist.wing 3 is pivoted the furthest up and the rearmost wing part 6 is pivoted the furthest down.
Der in F i g. 3 dargestellte Flügel besitzt zwei Teilflügel 3 und 4, die mit Klappen 8 und 10 versehen sind. Diese Klappen sind um die Achsen 9 und 11 schwenkbar.The in F i g. The wing shown in FIG. 3 has two wing parts 3 and 4, which are provided with flaps 8 and 10 are. These flaps can be pivoted about axes 9 and 11.
Die für eine wirksame Reduzierung des induzierten Widerstandes erforderliche Stellung der Klappen ist in F i g. 4 dargestellt.The position of the flaps required to effectively reduce the induced drag is in Fig. 4 shown.
Der mittlere Teil der Figur stellt eine Seitenansicht eines Tragflügels dar, wobei sich die Teilflügel 3 und 4 mit ihren Klappen 8 und 10 in Ruhestellung befinden. Die ausgeschwenkte Stellung der Teilflügel ist gestrichelt dargestellt. Der Teilflügel 3 ist nach oben, der Teilflügel 4 nach unten verschwenkt. Hierbei erkennt man, daß die Klappe 8 des Teilflügels 3 nach unten ausgelenkt ist, während die Klappe 10 des Teilflügels 4 nach oben ausgelenkt ist.The middle part of the figure shows a side view of an airfoil, with the partial wings 3 and 4 with their flaps 8 and 10 are in the rest position. The swiveled out position of the partial leaves is shown in dashed lines. The wing part 3 is pivoted upwards and the wing part 4 is pivoted downward. Here it can be seen that the flap 8 of the wing element 3 is deflected downwards, while the flap 10 of the wing element 4 is deflected upwards.

The flaps are supposed to be reduced in size. As is well known, the induced resistance from the swiveled-out position of the wing sections is invented in a wing by being set in such a way that the flap creates a spatial flow at the wing tips due to the pressure equalization between the lower wing and the front wing section the flap of the rear wing part is caused obliquely after mung, which is directed to the formation of a we- above. This results in an optimal rebel area behind the wing, whereby the reduction of the induced drag is achieved.
