Abstract
The invention relates to an aerodynamic profile for the root of a wind turbine blade having a double leading edge, including a leading edge (), a trailing edge () and suction and pressure sides () between the leading edge () and the trailing edge (). The profile (') has a relative thickness in the 30%-50% range in at least one section () of the root region (). In addition, the convex portion () of the pressure side () is configured such that the curvature thereof decreases from a value Cat the leading edge () to a value Cat a first point Pand subsequently increases to a value Cat a second point P, after which it decreases to a value 0 at the end of the convex portion ().
