FIELD: machine building.
SUBSTANCE: wind turbine blade containing aerodynamic fairing supported along part of its axial length of the spar (12). The spar contains two sections (12) connected end to end at the border (9) of contact and each having wall (3) working to shear, with flange (4) at each side. External surface (6) of each flange of the spar tapers inside in direction to the contact border to reduce its depth in direction to the contact border, creating cavity at each side of the contact border, created by tapered surfaces of the adjacent spar flanges. Corresponding connecting part (8) has size suitable to location in each cavity. Each connecting part (8) is made at tapered surfaces of the adjacent spar flanges to form double overlapping connection.
EFFECT: increased efficiency.
