A wind turbine rotor blade (1) with a suction side (13) and a pressure side (15) is provided. It comprises a cylindrical root portion (3) an airfoil portion (5) defining the suction side (13) and the pressure side (15), and a transition portion (7) which is located between the airfoil portion (5) and the root portion (3). The transition portion (7) has a transition profile changing from the airfoil of the airfoil portion (5) to the cylindrical profile of the root portion (3). The leading section of the transition profile is cylindrical and the trailing section of the transition profile is elongated. In the rotor blade, the maximum chord length of the airfoil portion (5) is at least the maximum chord length of the transition portion (7). In addition, the transition profile comprises a section with a concave curvature (25) on the pressure side (15) of the rotor blade (1). |
