Abstract
Official abstract text for this publication.
A wind turbine blade is provided. The wind turbine blade has multiple vortex generators, each projecting from a surface of the blade and having a predetermined length. The vortex generators are arranged on a strip. The width of the strip is several times larger than the length of a vortex generator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wind turbine blade, comprising: a strip; and a plurality of vortex generators arranged on the strip, wherein each of the vortex generators projects from a surface of the blade and comprises a predetermined length, wherein a width of the strip is 2 to 10 times larger than the length of each of the vortex generators, wherein an adhesive is applied on a lower surface of the strip, and wherein the lower surface of the strip is provided with a countersink groove along a longitudinal direction of the strip. 2. The wind turbine blade according to claim 1 , wherein a double-sided adhesive tape is applied on the countersink groove. 3. The wind turbine blade according to claim 1 , wherein a first end of the strip is provided with a predetermined shape and a second end of the strip is provided with a mating shape. 4. The wind turbine blade according to claim 3 , wherein the first end and the second end of the strip are shaped as tongue and groove.
