摘要
Blade for vertical-axis wind turbine, comprising a central body (5) that is extended along a longitudinal extension line (1) substantially helical around an axis (Z) with an aerodynamic profile (P) orthogonal thereto, between an upper end (5'), defined by a horizontal upper end section (Ss) orthogonal to the vertical axis (Z) and tilted with respect to the longitudinal extension line (1), and a lower end (5"), defined by a horizontal lower end section (Si) orthogonal to the vertical axis (Z) and tilted with respect to the longitudinal extension line (1). Each of the blades (3) further comprises two appendages (6) respectively connected to the upper end (5') and lower end (5 ") of the central body (5) and each being extended along a radial direction (R) substantially orthogonal to the vertical axis (Z) towards the central rotation shaft (2) starting from a root end (7) defined by a root section (7'), lying on a plane substantially vertical and orthogonal to the radial direction (R).;The appendages (6) are connected to the upper end (5') and lower end (5") of the central body (5) by means of respective connector portions (9), each of which is extended between the horizontal upper end section (Ss) or lower end section (Si) of the central body (5) and the root section (7) of the corresponding appendage (6).;Also forming the object of the invention is a vertical-axis turbine comprising two or more blades according to the present invention.
