초록

Wind turbine blade (10) including adjustable lift-regulating means (12, 13, 15, 17, 19, 21) arranged on or at the surface of the wind turbine blade (10), said lift-regulating means being provided with activating means by means of which they can be adjusted and thus alter the aerodynamic properties of the blade (10). The lift-regulating means (12, 13, 15, 17, 19, 21) and the activating means are adapted and arranged such that by activation of the activating means, the lift can be reduced in a zone extending in the longitudinal direction of the blade (10) ...

청구항

The invention claimed is: 1. Wind turbine blade including adjustable lift-regulating means arranged on or at a surface of the wind turbine blade and extending in a longitudinal direction of the blade, and activating means by which the lift-regulating means can be adjusted and thus alter the aerodynamic properties of the blade, the lift-regulating means and the activating means being adapted and arranged such that by activation of the activating means, the lift can be reduced in a zone extending in the longitudinal direction of the blade from a first pos...
