Wind turbine rotor blade and method for defrosting a wind turbine rotor blade

摘要

There is provided a wind turbine rotor blade having a rotor blade nose (11), a rotor blade trailing edge (12), a rotor blade root portion (14) for mounting the rotor blade to a hub of a wind turbine and a rotor blade tip (13). The rotor blade extends from the rotor blade root region (14) along a longitudinal axis to the rotor blade tip (13). The rotor blade further comprises an air distribution unit (500) with an actuator (540) for directing an airflow into the rotor blade nose region (11) and / or a rotor blade trailing edge region (12).
