Abstract
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.
