A longitudinally extending flying surface in the form of a box-like structure, floats on and surrounds a frame including a spar, in the chordal plane. Two suitable links mounted at a spanwise distance between them, link the spar with the flying surface: they cooperate with themselves to form two fixed points of intercept with respect to the flying surface, of the curvature of flexion covered by the spar on the flying surface in the chordal plane: they permit the free flex of the spar relatively to the flying surface in the chordal plane, during the axial rotation of the spar. In a modified wing the spar and a plurality of non spherical bearings coaxial with the spar provide the framework, and the wing sheets forming flying surfaces are able to slide on such a framework: the assembly has no structure between the wing sheets and the bearings, and no contacting structure surrounding the circumference of the bearings, and maintains a space flanking the bearings in the chordal plane to allow the movement of the bearings according to the curvature of flexion of the spar, such that during rotation of the flying surface, the spar can freely flex for the whole of its span relatively to the flying surface in the chordal plane.
