    摘要： A wind turbine blade airfoil trailing edge (TE) with a first waveform profile (44B, 44C, 44E) as seen from behind, formed by ruffles or alternating ridges (21) and valleys (22) formed on the airfoil (20) and ending at the trailing edge. The trailing edge may further include a second waveform profile (48B, 48C, 48E) as seen from above, resulting from serrations formed by an oblique termination plane (32B) of the trailing edge or by other geometry. The ridges and/or serrations may be asymmetric (44E, 48E) to increase a stall fence effect of the ridges on the suction side (SS) of the trailing edge. The first and second waveforms may have the same period (44B, 48B) or different periods (44C, 48C).

    摘要： A wind turbine blade (80, 82) having a spanwise series of vortex generators (26, 28, 26P, 28P, 64, 66) and having a trailing edge (42) defining a waveform. The vortex generators are aligned with a predetermined position or phase (44, 46) of a respective period of the trailing edge waveform. Each vortex generator may be designed to create a vortex (27, 29) that crosses the trailing edge at an angle of less than 30 degrees from parallel to the trailing edge. The blade may include alternating ridges (52) and troughs (54) that end at the waveform trailing edge. A front end of each trough may form a V-shaped drop-off in the suction side of the blade that forms a pair (64, 66) of vortex generators to create counter-rotating vortices within the trough that entrain energy to the bottom of the trough.

    摘要： A wind turbine blade is described having noise reduction features. The blade has a plurality of projecting serrations provided at the blade trailing edge to reduce the scattering noise produced during operation of the blade, wherein the serrations have a plurality of through-going apertures defined in the serration body. The apertures act to provide a pressure equalisation effect at the serrations between the suction and pressure sides. This pressure equalisation provides for improved noise reduction performance, as well as a reduction in mechanical stresses and strains which may be experienced by the serrations, increasing serration lifetime.
