The invention concerns a rotor blade, in particular a rotor blade of a wind power installation. The object of the present invention is to provide measures for still further improving the CR-value and also the level of acoustic power of rotor blades of wind power installations. A rotor blade for a wind power installation comprising a pressure side and a suction side, wherein a substantially constant, area-covering electrostatic field is provided on the suction side.
L'invention concerne une pale de rotor, notamment une pale de rotor pour installation d'énergie éolienne. L'invention vise à mettre au point des mesures, visant à perfectionner le coefficient de résistance aérodynamique, de même que le niveau de puissance acoustique de pales de rotor d'installations d'énergie éolienne. La pale de rotor d'installation d'énergie éolienne selon l'invention est munie d'un intrados et d'un extrados, un champ électrostatique étendu, sensiblement constant étant formé sur l'extrados.
