Abstract
A rotor blade for a wind turbine has a rotor blade root defining a reference plane for attachment to a hub. Adjacent to the rotor blade root is a profile region extending to the rotor blade tip. In the profile region, the rotor blade has a blade profile defining a chord. The chord angle between the reference plane and the chord increases over the entire profile region, from the rotor blade root towards the rotor blade tip.
