Abstract (en)
[origin: US2014234115A1] A radially twisted wind turbine blade (10), including a radially twisted spar web (122), wherein a center (78) of a radial cross section of a base (12) of the blade rotates within a plane of rotation (80), and wherein at a base (12), a radial cross section of the spar web forms a first angle (82) with the plane of rotation, and at a tip (32) a radial cross section of the spar web forms a second angle (130) with the plane of rotation different than the first angle.
