Beschreibung
Zusammenfassung:	A blade for a rotor of a wind turbine having a longitudinal direction with a tip end and a root end and a transverse direction, comprising: a profiled contour that when impacted by an incident airflow, generates a lift, wherein the profiled contour is divided into: a root region having a substantially circular or elliptical profile closest to the hub, an airfoil region having a lift-generating profile furthest away from the hub, and a transition region between the root region and the airfoil region, the transition region having a profile gradually changing in the radial direction to the lift-generating profile of the airfoil region, and further comprising a shoulder, wherein the shoulder is located in the airfoil region, thus yielding a slender and relative thick blade maximizing energy output, reducing bearing loads and facilitating transportation.
