ABSTRACT:
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 includes a high pressure side and a low pressure side. A substantially constant, area-covering electrostatic field is provided on the low pressure side.
