Wind Turbine With Bent Rotor Blades

Patent No. EP1596063 (titled "Wind Turbine With Bent Rotor Blades") was filed by Repower Systems on May 4, 2005. The application was issued on Sep 28, 2016.

Patent Summary

A wind turbine comprises a tower, a nacelle mounted on the tower's upper end, and a rotor rotatable about a rotor axis of rotation. The rotor includes a rotor hub and at least one rotor blade extending therefrom. The rotor blade is arranged on the rotor hub such that it is oriented with an inclination away from the tower at an obtuse angle relative to the rotor axis of rotation. To minimize performance degradation and reduce the required inclination angle while preventing tower collisions, the rotor blade is designed to be curved with respect to its longitudinal axis in at least one length section. This combination of an obtuse inclination and longitudinal curvature optimizes structural loads and aerodynamic efficiency.
