Aircraft wing comprising a leading edge mobile flap shutter equipped with a follow-up rail with movement restricted according to an arc of circle trajectory

摘要

The wing (4) has a movement device moving a mobile flap (16) of a leading edge and with a follow-up rail (50) extending along a guiding line in the form of an arc of circle (60) centered on a rotational axis (18) of the flap. The follow-up rail is placed between two drive rails and permits following-up displacement of the flap. Guiding systems (56) guide the follow-up rail, and are connected on a fixed central body (8). The guiding systems restrain the follow-up rail in displacement such that the line remains superimposed to a path in the form of an arc of circle (62) centered on the axis.
