| 摘要 |
The objective of this invention is to obtain rotor blades for large-sized horizontal axis wind turbines that allow easy transport, handling and storage at the same time guaranteeing greater efficiency in the use of wind energy. The present invention results in a blade (4) made up of two or more elements (5,6,9) arranged collaterally and preferably fixed among themselves such as to cause an aerodynamic interference between said elements.
