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.
Claims19
A wind turbine blade comprising an aerodynamic device mounted to an outer surface of the blade, the aerodynamic device comprising a baseplate having an inner surface defining a mounting region and a sealing region at least partially surrounding the mounting region, wherein:
- 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 surrounding the mounting region;
- and
- a barrier is provided between the seal and the adhesive, the barrier being arranged substantially to prevent contact between the seal and the adhesive,
- wherein the sealing region comprises a skirt at least partially surrounding the mounting region, the skirt being arranged to cover the seal.
A wind turbine blade comprising an aerodynamic device mounted to an outer surface of the blade, the aerodynamic device comprising a baseplate having an inner surface defining a mounting region and a sealing region at least partially surrounding the mounting region, wherein:
- 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 surrounding the mounting region;
- and
- a barrier is provided between the seal and the adhesive, the barrier being arranged substantially to prevent contact between the seal and the adhesive,
- wherein the barrier comprises a plurality of ridges that are spaced apart such that channels are defined between adjacent ridges.
A wind turbine blade comprising an aerodynamic device mounted to an outer surface of the blade, the aerodynamic device comprising a baseplate having an inner surface defining a mounting region and a sealing region at least partially surrounding the mounting region, wherein:
