The invention relates to an aerofoil (T) comprising a main wing and a high lift flap (K) which is movably mounted on the aerofoil (T) by means of at least two adjusting mechanisms (1, 2) that are located next to one another in the direction of the span of the aerofoil (T) and that are adjusted by means of a drive device (50), each of said adjusting mechanisms (10) having: a first adjusting lever (11, 21), hinged to the main wing by means of a first pivot joint (13, 23), forming a first rotational axis (A11, A21); a second adjusting lever (12, 22), hinged to the high lift flap (K) by means of a second pivot joint (23), forming a second rotational axis (A21, A22), a central joint (15, 25) which hinges the first adjusting lever (11, 21) to the second adjusting lever (12, 22), forming a third rotational axis (A31, A32). An intermediate joint part (Z) for coupling the first adjusting lever (11, 21) to the main wing (H), or for coupling the second adjusting lever (12, 22) to the high lift flap (K) is located on at least one of the adjus-ting mechanisms (1, 2).

L'invention concerne une surface portante (T) constituée d'une aile principale (H) et d'un volet hypersustentateur (K) monté mobile sur la surface portante (T) à l'aide d'au moins deux mécanismes de déplacement (1, 2) juxtaposés dans le sens de l'envergure de la surface portante (T) et pouvant être déplacés au moyen d'un dispositif d'entraînement (50), chaque mécanisme de déplacement (10) comprenant un premier levier de déplacement (11, 21) qui est articulé sur l'aile principale par l'intermédiaire d'une première articulation tournante (13, 23) avec formation d'un premier axe de rotation (A11, A21), un second levier de déplacement (12, 22) qui est articulé sur le volet hypersustentateur (K) par l'intermédiaire d'une seconde articulation tournante (23) avec formation d'un deuxième axe de rotation (A21, A22), ainsi qu'une articulation centrale (15, 25) qui relie entre eux de manière articulée le premier (11, 21) et le second (12, 22) levier de déplacement avec formation d'un troisième axe de rotation (A31, A32). Une pièce intermédiaire d'articulation (Z) permettant d'accoupler le premier levier de déplacement (11, 21) et l'aile principale (H) ou d'accoupler le second levier de déplacement (12, 22) et le volet hypersustentateur (K) est placée sur au moins un des mécanismes de déplacement (1, 2).
