METHOD FOR DETERMINING ARRANGEMENT POSITION OF VORTEX GENERATOR ON WIND TURBINE BLADE, METHOD FOR PRODUCING WIND TURBINE BLADE ASSEMBLY, AND WIND TURBINE BLADE ASSEMBLY

摘要

A wind turbine blade comprising a vortex generator including a plurality of fins. The plurality of fins include a first fin positioned closest to a blade tip, and the first fin is disposed closer to a blade root than a position closer to the blade tip, of a blade spanwise directional position at which a ratio t/C of a blade thickness ‘t’ to a chord length C is 0.4 or a radial directional position of 0.2 R with respect to a radius R of a rotor including the wind turbine blade. The vortex generator may include at least one fin disposed in a mounting range of zero to 0.1 R, such that a ratio x/C of a chordwise directional position x of the at least one fin to the chord length C satisfies 0≤x/C≤0.2.
