Rotor blade for wind-energy plant, has main blade and auxiliary blade that is radially diverging from main blade with respect to wind-induced rotation, where blade cross-section is tapered from hub in radial direction
The blade (10) has a main blade (1) and an auxiliary blade (2) that is radially diverging from the main blade with respect to a wind-induced rotation. A blade cross-section (N10) is tapered from a hub in a radial direction, where the cross-section is twisted in a circularly flattening manner. Main blade ends (E1) are arranged at a distance from adjacent auxiliary blade ends (E2). The auxiliary blade ends exhibit a leeward-side auxiliary blade offset to the main blade end with respect to an arising wind, where the auxiliary blade offset is larger than a thickness of the main blade end. An independent claim is also included for a wind-energy plant with a tower.
