Title: Rotor Blade for a Wind Power Installation
IPC: F03D7/02
Filed: 2000-12-19
Abstract: The invention concerns a rotor blade for a wind power installation. The degree of efficiency of rotor blades is determined by the afflux angle, that is to say the angle between the rotor blade profile chord and the afflux direction of the air. Particularly in the case of wind power installations the afflux angle depends on the rotor blade speed-that is to say the speed of rotation of the rotor-and the wind direction: the afflux direction is distinguished by the sum vector of the wind speed v<SUB>Wind </SUB>and the speed of the rotor blade tip v<SUB>Tip</SUB>, the effective afflux speed v<SUB>eff</SUB>, see FIG. 1, <?in-line-formulae description="In-line Formulae" end="lead"?>v<SUB>eff</SUB>=√{square root over (<SUB>Wind</SUB><SUP>2</SUP>)}+v<SUB>Tip</SUB><SUP>2</SUP> (1)<?in-line-formulae description="In-line Formulae" end="tail"?> The object of the invention is therefore that of reducing the sensitivity of a rotor blade to turbulent wind flows. A rotor blade for a wind power installation which is divided in its longitudinal direction into at least two portions which are integrally connected together and which are designed for different high-speed indexes, wherein the high-speed index, associated with the maximum power coefficient, of the portion which is further away from the rotor blade root is greater than the high-speed index, associated with the maximum power coefficient, of the portion respectively disposed closer to the rotor blade root.
