An advantageous new design of a wind turbine blade and rotor is obtained by providing one, two or more parallel rows of sub-boundary layer vortex generators, whereby a blade is obtained, which is resistant to stall and provides for a high maximum lift coefficient CL,max of the blades and a slender blade design, a low socalled radius specific solidity of the rotor. The very high lift coefficient CL can reduce the necessary blade area and loads or/and increase the length of the blade and maintain the original loads with higher production. The row or rows o...


What is claimed is: 1. A wind turbine blade comprisinga first row of vortex generators arranged in a longitudinal direction of the blade on a suction side thereof, wherein a height of said vortex generators comprising the first row in a direction away from a surface of the blade is within the range of 0.1% to 0.65% of a chord length of the blade, anda second row of vortex generators arranged in the longitudinal direction of the blade on the suction side thereof, wherein a height of said vortex generators comprising the second row in a direction away from...
