The invention relates to a contoured wing intended to serve as a airfoil or a blade. This wing comprises a longitudinal stringer (3), a plurality of juxtaposed wing sectors (1, 2), each articulated about the stringer, a series of cranks (7), each crank associated with a sector in such a manner as to fix the angular position thereof about the stringer, and a control device (10) for the cranks, able to cause their pivoting. The wing according to the invention permits control of the angle, continuously and progressively variable along the contour. It may particularly be applied for use in beating wing aircraft.

A profiled wing for use as an airfoil or a blade, comprising an axial stringer (3), a plurality of wing sectors (1, 2) juxtaposed along said wing, each of said sectors being articulated on said stringer so as to be pivotable therearound, angular positioning means for positioning said sectors with respect to said stringer, said angular positioning means for said sectors comprising a series of cranks (7, 23, 29) one associated with each sector in such a manner as to fix the angular position of said sector with respect to said stringer (3), and control means for said cranks (10) for causing pivotal movement of said cranks and thereby establishing a predetermined position for each of said cranks as a function of the desired angle for each sector of the wing (1, 2), each sector being covered by a deformable covering surface (11, 12) resting upon two ribs (6), and said deformable covering comprising, at the point of each sector, a top surface (11) and a bottom surface (12) able to undergo a twisting motion and maintained against two adjacent ribs (6) in such a manner as to be able to slide independently one with respect to the other when said ribs assume different angles.
