Abstract
A wind turbine blade comprising at least one central spar longitudinal section and at least two shell longitudinal sections forming, respectively, the leading edge and the trailing edge of the corresponding blade section. The central spar is composed of two cap prefabricated panels and two web prefabricated panels placed side by side in a box shape. The shell longitudinal sections are placed adjacently to the central spar section and are composed of a single prefabricated panel or of two prefabricated panels. The aerodynamic profile of the blade being defined by the cap panels and the single shell panels or two shell panels.
Claims16
A wind turbine blade comprising at least one central spar longitudinal section (7) and at least two shell longitudinal sections (5, 9), wherein:
- a) each central spar section (7, 7′, 7″) is composed of only two cap prefabricated panels (15, 17) and two single-piece web prefabricated panels (19, 21) placed side by side in a box shape;
- b) each shell section (5, 5′, 5″, 5′″, 5″″;
- 9, 9′, 9″, 9′″) forming, respectively, a leading edge and a trailing edge of the corresponding blade section is placed adjacently to a central spar section (7, 7′, 7″);
- c) each shell section (5, 5′, 5″, 5′″, 5″″;
- 9, 9′, 9″, 9′″) is composed of at least a single prefabricated panel (31, 33);
- d) an aerodynamic surface of the blade is composed of just said cap panels (15, 17) and shell prefabricated panels (31;
- 33);
- and
- e) joints between panels are carried out by chemical and/or mechanical joints.
