30 THICKNESS AIRFOIL FOR LARGE SCALE WIND TURBINE BLADE

摘要

The present invention relates to a 30% thickness airfoil for a large scale wind turbine blade. The 30% thickness airfoil for a large scale wind turbine blade according to one embodiment of the present invention is used for a wind turbine. According to one embodiment of the present invention, the airfoil has an upper surface and a lower surface. The thickness is 30% of a cord length. According to one embodiment of the present invention, a maximum ratio (lift coefficient/drag coefficient) in free transition is 146. A maximum ratio in forced transistor is 92. More particularly, in an aspect of the present invention, the 30% thickness airfoil for a large scale wind turbine blade can include other embodiments.
