Abstract
A blade (1) for a rotor of a wind turbine having a substantially horizontal′ rotor shaft, said rotor comprising a hub, from which the blade extends substantially radially from said rotor when mounted. The blade (1) has a chord plane (K) extending between the leading edge (5) and the trailing edge (S) of the blade (1). The blade (1) comprises a root area (2) closest to the hub, an airfoil area (4) furthest away from the hub and a transition area (3) between the root area (2) and the airfoil area (4), and comprises a single airfoil along substantially the entire airfoil area (4). The blade (1) comprises at least a first root segment (7) and a second root segment (8) along substantially the entire root area (2), said segments being arranged with a mutual distance, as seen transverse to the chord plane (K). At least one of the root segments (7, 8) has an airfoil profile.
