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). The outer aerodynamic shell (20) comprises a suction side panel (31) and a pressure side panel (33) which are made from a transparent material and are fastened to the blade structure (7) so as to define the airfoil suction side and the airfoil pressure side (28, 29), respectively, wherein said blade (6) comprises a transparent region (40) between said transparent panels (31, 33) and wherein said transparent panels (31, 33) are arranged facing one another so that it is possible to see through the blade (6) looking through said transparent panels (31, 33) and said transparent region (40). A method for assembling the blade (6) is also described. |
