Abstract:
1. A control device on the suction-face side of a lift-generating surface of an aircraft for controlling at least one vortex trail generated by at least one oblong element which is mounted under this lift-generating surface protruding partially beyond the leading edge of said lift-generating surface in the upstream direction, said device comprising at least one control means: which is arranged at the level of said oblong element; and which has an elongate shape, its longitudinal axis being substantially parallel to a local fluid flow and its upstream end being pointed, wherein said control means: is produced in the form of a point which is triangular both when viewed from the side and when viewed from the top; is arranged both on a fixing element used to secure the oblong element and on the lift-generating surface in such a way that the base of said point, which corresponds to its downstream end, is brought into contact with the leading edge of said lift-generating surface; and has a shape which is substantially triangular in a plane perpendicular to said longitudinal axis and which has a first side intended to come into contact with said fixing element and two adjacent sides forming flanks, said flanks being joined together by a rounded edge.
