摘要： A rotor blade for a wind turbine is provided. The rotor blade includes a pressure side, a suction side, a leading edge section with a leading edge, and a trailing edge section with a trailing edge. An airflow flows along the surface of the rotor blade from the leading edge section to the trailing edge section and builds up a boundary layer in close proximity to the surface of the rotor blade. The rotor blade includes a noise reduction device for reducing noise which is generated by interaction of the airflow and the rotor blade. The noise reduction device is located within the boundary layer of the rotor blade. The noise reduction device includes a cover and connection device for connecting the cover to the surface of the rotor blade. The cover spans at least over a part of the surface of the rotor blade.

摘要： A rotor blade of a wind turbine including an aerodynamic device which can be actuated pneumatically by the use of a pressure supply system is provided. The pressure supply system includes a pressurized air supply system, a pressurized air transmission system with pressure lines for transmitting the supplied pressurized air from the pressurized air supply system to the aerodynamic device, at least one pneumatic actuator for activating the aerodynamic device, and a safety system to protect the rotor blade from damages caused by overpressure in the pressurized air transmission system and/or the actuator. The safety system includes means for discharging pressurized air from the pressurized air transmission system and/or the actuator. Also provided is a wind turbine for generating electricity including at least one such rotor blade.
