AIRCRAFT WING WITH DISPLACEABLE WINGLET

AIRCRAFT WING WITH DISPLACEABLE WINGLET

A wing having a main wing section (11) with a forward spar (14A) and an aft spar (14B) extending through an internal cavity. The forward and aft spars are spaced apart and delimiting a dry segment of the internal cavity (19). A winglet (20) is rotatably coupled to the main wing section (11) by a can...

Zusammenfassung:A wing having a main wing section (11) with a forward spar (14A) and an aft spar (14B) extending through an internal cavity. The forward and aft spars are spaced apart and delimiting a dry segment of the internal cavity (19). A winglet (20) is rotatably coupled to the main wing section (11) by a cant hinge (30) defining a cant axis (32) about which the winglet (20) rotates relative to the main wing section (11) between an extended position in which the winglet (20) is aligned with the main wing section (11), and a folded position in which the winglet (20) is rotated about the cant axis (32). A linkage assembly (40) disposed in the dry segment is pivotably mounted to one of the forward and aft spars (14A, 14B) and is coupled to the cant hinge (30). The linkage assembly (40) is displaceable to apply a force to move the winglet (20) between the extended position and the folded position during flight of the aircraft.
