Beschreibung
Zusammenfassung:	The installation has a drive unit rotatably driving a Magnus effect rotor i.e. blade of wind turbine. The rotor comprises structured surfaces on a portion of an outer surface of the rotor to optimize hydro/aerodynamic characteristics of the rotor with respect to fluid in turbulent flow. The structured surfaces are chosen from two-dimensional, three-dimensional transverse wave and/or orthogonal meridian wave microstructure, where the rotor is installed on a ship. La présente invention concerne une installation comprenant des moyens pour la réduction de l'énergie d'entraînement des rotors à effet Magnus par réduction de la traînée aérodynamique (réduction du facteur de friction) au moyen d'une stabilisation et/ou l'atténuation de la turbulence pariétale, tout en augmentant la dissymétrie de l'écoulement correspondant à une augmentation de l'effet Magnus. Cette installation est particulièrement bien adaptée à l'utilisation de rotors à effet Magnus pour le déplacement des bateaux et les éoliennes.
