Abstract: It is described a blade (6) for a wind turbine (1) for converting wind energy into electric energy, comprising: -a blade structure (7) longitudinally extending along a blade axis (X1) and comprising a blade tip (11), an opposite blade root (12), a longitudinal leading edge portion (13) and a longitudinal trailing edge portion (14) which are extended between the blade root (12) and the blade tip (11); and -an outer aerodynamic shell (20) defining an airfoil (25) including an airfoil leading edge (26), an airfoil trailing edge (27) and an airfoil suction side and an airfoil pressure side (28, 29) between said airfoil leading and trailing edges (26, 27).

Abstract: A wind turbine (1) is disclosed, for converting wind energy into electric energy, comprising:—a shuttle (2) comprising a head portion (11) and a tail portion (12);—a primary wind rotor (3) pivotable with respect to the shuttle (2) around a primary rotational axis (A1) and comprising a primary group of blades (4), a fastening hub (5) for said blades (4) projecting from the head portion (11) of the shuttle (2) and a shaft adapted for being rotatably moved by the primary wind rotor (3);—at least one primary electric generator comprising at least one primary electric stator integral with the shuttle (2) and a primary electric rotor integral with said shaft or operatively connected to it, the primary electric generator adapted to convert wind energy intercepted by said primary group of blades (4) into electric energy.
