A device for accelerating the destruction of contra-rotating vortices formed at the rear of wings of a moving body by the merging of at least two co-rotating eddies includes, on each of the wings, at least one perturbator which is positioned in the vicinity of the area of creation of one of the co-rotating eddies associated with the wing. Each of the perturbators generates a periodic perturbation of the flow, which has a wavelength capable of exciting at least one of the instability modes of the corresponding eddy in such a way as to increase the core of the contra-rotating vortex which is created from this eddy, in such a way that the diameter of the core becomes greater than a predetermined proportion of the inter-vortex distance.
