Abstract

The invention relates to a rotor blade for a Darrieus H rotor. The aim of the invention is to reduce the noise produced by the rotor and to improve its starting properties. The upper and lower ends of the rotor blades are therefore bent outward and away from the rotor axis to some extent in relation to the rest of the rotor blade and the upper and lower sections of the leading edge of the rotor blades are bent backward to some extent in the direction of movement when in operation in relation to the center section of the leading edge.
