摘要：
A wind turbine blade apparatus at least includes a wind turbine blade body, wherein a serration portion is disposed on at least on a part of a trailing edge of the wind turbine blade body, the serration portion having a saw-teeth shape where a mountain portion and a valley portion are arranged alternately in a blade longitudinal direction, and wherein a chord-directional cross section of the wind turbine blade body along a chord direction is formed to have an airfoil shape at any position in a region from the mountain portion to the valley portion.
