摘要： A rotor blade of a wind turbine, having a rotor blade length, a rotor blade depth extending over the rotor blade length, a rotor blade thickness extending over the rotor blade length, and a thickness of a trailing edge of the rotor blade extending over the rotor blade length, wherein, in a region of the rotor blade length, the rotor blade simultaneously has a splitter plate that has a predetermined length and a Gurney flap that has a predetermined height, wherein a ratio of the predetermined height of the Gurney flap to the predetermined length of the splitter plate at a particular position in the direction of the rotor blade length is selected in such a manner that a threshold value that decreases with a relative profile thickness, which is defined as a ratio of the rotor blade thickness to the rotor blade depth, is not reached.

摘要： The present disclosure is directed to a rotor blade having a passive airflow modifying assembly to create an airflow feature along the blade, based on the instant pressure gradient around the blade during operation. The present disclosure also is directed to a rotor blade that passively channels airflow through the passive airflow modifying assembly to create an air feature that decreases the aerodynamic load, at times when the aerodynamic load experienced by the blade is bearing on the rotatable hub, and one the passively channels airflow through the passive airflow modifying assembly to create an air feature that increases the aerodynamic load, at times when the aerodynamic load is not bearing on the rotatable hub, and one that passively operates to not create an air feature, at times when the requisite pressure gradient is not met and/or when the load conditions are not an issue.

摘要： Wind turbine blade having a length L, an airfoil with a chord C, and a first Gurney flap attached to the pressure or the suction surface of the airfoil near the trailing edge of the wind turbine blade. The first Gurney flap extends along at least 50% of the length of the outer ⅓rd of the wind turbine blade. By mounting the Gurney flap to the outer portion of the blade, the lift of the outer portion of the blade can be increased or decreased depending on the conditions in which the wind turbine is operating.
