    Abstract: Wind turbine rotor blade with reduced trailing edge noise A wind turbine rotor blade is described, the rotor blade extending in a spanwise direction between a root end and a tip end, and extending in a chordwise direction between a leading edge and a trailing edge. The rotor blade comprises a series of serrations projecting from the trailing edge, each serration extending from a base to a tip to define a length of the serration. The rotor blade also comprises a respective distinct set of fins associated with, and arranged adjacent to, each of the serrations, each fin projecting from a surface of the blade and extending between a leading end and a trailing end to define a length of the fin. Each set of fins comprises multiple fins whose trailing ends are in spanwise alignment with, and are located at or upstream of, the base of the serration associated with the set. For each set of fins, each fin of the set has a greater length than the serration associated with the set, and the trailing end of at least one fin lies between spanwise edges of the serration associated with the set.

    Abstract: An aerodynamic device is described for mounting to an outer surface of a wind turbine blade. The aerodynamic device includes a baseplate having an inner surface defining a mounting region and a sealing region at least partially surrounds the mounting region. The mounting region is bonded to the outer surface of the blade by an adhesive. A seal is provided between the sealing region of the baseplate and the outer surface of the blade. The seal at least partially surrounds the mounting region. A barrier is provided between the seal and the adhesive. The barrier is arranged substantially to prevent contact between the seal and the adhesive.
