| description | The utility model relates to the technical field of wind turbine blades, in particular to a wind turbine blade with a suction surface acceleration channel, which comprises a first blade and a plurality of small airfoil blades, and the small airfoil blades are symmetrical airfoil and are smaller than the first blade in volume; the multiple small-wing-shaped blades are distributed at intervals in the spanwise direction of the first blade, and an airflow acceleration channel is defined between every two adjacent small-wing-shaped blades; the small wing-shaped blade is fixedly installed on the suction surface of the first blade, and the lower surface of the small wing-shaped blade is tightly attached to the suction surface of the first blade. According to the utility model, when the power generation operation is carried out, the airflow speed of the suction surface is improved due to the existence of the airflow acceleration channel, so that the pressure of the suction surface is reduced, and the lift performance |
