The present invention relates to a wind turbine blade () with an access window () extending through a shell body of the blade. A frame (), which defines an opening (), is arranged on top of the outer surface of the blade such that the opening of the frame () is aligned with the access window. A cover member () covers the opening () of the frame and releasably closes the access window.

Wind turbine rotor blade with framed access window

A noise reduction element extends between a first end and a second end in a first direction. The noise reduction element extends between a third end and a fourth end in a second direction perpendicular to the first direction. The noise reduction element includes a base part configured to be attached to a trailing edge of a wind turbine blade. The base part has a first base part surface and a second base part surface. The base part extends between the first end and a first position in the first direction. The noise reduction element includes a first serration part having a serration pressure surface and a serration suction surface and extending in the first direction between the first position and the second end. The first serration part has a thickness in a third direction between the serration pressure surface and the serration suction surface.
