Abstract:
1. A wind turbine blade ( 1 ) having an aerodynamic profile with a root region, leading edge ( 13 ), a trailing edge ( 15 ) and suction and pressure sides ( 17 , 19 ) between the leading edge ( 13 ) and the trailing edge ( 15 ), the pressure side ( 19 ) having a first convex part ( 21 ) and a second concave part ( 23 ), the convex part ( 21 ) of the pressure side ( 19 ) being shaped so that its curvature decreases from a value (C 0 ) in the leading edge ( 13 ) to a value (C 1 ) in a first point (P 1 ), then increases up to a value (C 2 ) in a second point (P 2 ) and then decreases up to a 0 value at the end of the convex part ( 21 ), wherein at least a section ( said first point (P said second point (P the value (C
