RippenklappmechanismusRib folding mechanism Beschreibung:Description:

Die Erfindung betrifft die Konstruktion von Tragflächen für leichte Fluggeräte.The invention relates to the construction of wings for light aircraft.

Die Erfindung verbindet die Vorteile einer festen Flügelkonstruktion mit der einer flexiblen, zusammenlegbaren Flügelkonstruktion.The invention combines the advantages of a fixed wing construction with those of a flexible, collapsible wing construction.

Der Zweck des Rippenklappmechanismus ist die Verringerung der Flügeltiefe einer aerodynamisch hochwertigen Tragfläche. Der Transport wird dadurch erleichtert.The purpose of the rib folding mechanism is to reduce the chord of an aerodynamically high-quality wing. This makes transportation easier.

In dem möglichen Einsatzgebiet bei leichten Fluggeräten (z.B. Hängegleitern) sind derzeit einerseits zusammenlegbare Tragflächen, deren Profil und Flächenform siöh.bei-verschiedenen Geschwindigkeiten negativ verändern und andererseits feste Tragflächen, die sohlecht transportiert werden können, bekannt. Die technische Aufgabenstellung bestand darin, eine aerodynamisch hochwertige Tragfläche zu konstruieren, die dennoch mit geringem Aufwand auf- bzw. abzurüsten ist· Der Flügel besteht aus einem tragenden Torslonskaeten in bewährter Bauweise (Holz-Kunststoff-Leichtmetall-Gemischtbauweise) im vorderen Drittel der Tragfläche und einer mit Gelenken am Torsionskaeten befestigten Rippenkonstruktion, die dem Bespannstoff im hinteren Bereich der Tragfläche die Form gibt. Durch diese Konstruktion läßt sich die Flügeltiefe für den Transport erheblich verkleinern, wobei die gleiche aerodynamische Güte wie bei einer festen Tragflächenkonstruktion erreicht werden kann.In the possible field of application for light aircraft (e.g. hang gliders), folding wings are currently known, whose profile and surface shape change negatively at different speeds, and fixed wings that can be transported on their own. The technical task was to design an aerodynamically high-quality wing that can nevertheless be upgraded or dismantled with little effort. The wing consists of a load-bearing torsion bar in a proven design (wood-plastic-light metal mixed construction) in the front third of the wing and a rib structure attached to the torsion bar with joints, which gives the covering material in the rear area of the wing its shape. This design allows the wing depth to be reduced considerably for transport, while achieving the same aerodynamic quality as with a fixed wing structure.
