BLADE FOR WIND TURBINE AND METHOD OF ASSEMBLY OF THE BLADE Russian patent published in 2016 - IPC F03D1/06 

FIELD: turbines.

SUBSTANCE: invention concerns blade (6) for wind turbine generator (1) and wind turbine generator (1) and method for assembling blade (6) and wind turbine generator (1). Blade (6) for wind turbine generator (1) comprises blade structure (7), longitudinally extending along blade axis (X1) and comprising blade tip (11), opposite blade root (12), longitudinal leading edge portion (13) and longitudinal trailing edge portion (14), which are extended between blade root (12) and blade tip (11); outer aerodynamic shell (20) defining airfoil (25), including airfoil leading edge (26), airfoil trailing edge (27) and airfoil suction side airfoil pressure side (28, 29), arranged between said airfoil leading and trailing edges (26, 27). Outer aerodynamic shell (20) comprises suction side panel (31) and pressure side panel (33), which are made from a transparent material and are fastened to blade structure (7) so as to define airfoil suction side and airfoil pressure side (28, 29), respectively, wherein blade (6) comprises transparent region (40) which is arranged between transparent panels (31, 33) and wherein said transparent panels (31, 33) are arranged facing one another.

EFFECT: invention is aimed to increase strength of the blade for wind turbine generator and reduce negative visual impact of the wind generator on the surrounding environment.
