Abstract: The present invention relates to a wind turbine blade with an access window extending through the blade. A cover member for covering the access window is provided, such that a first end of the cover member is pivotally connected to the outer surface of the blade and a second end of the cover member is releasably fastened to the outer surface of the blade.

Abstract: A method of joining first and second blade components of a rotor blade of a wind turbine includes arranging the first blade component and the second blade component together at an interface. The first and second blade components are formed of different materials having different stiffnesses. The method further includes providing at least one gap at the interface of the blade components. Further, the method includes securing the blade components together by at least partially filling the gap with at least one filler material. Moreover, the method includes further securing the blade components together via an infusion process, wherein, during the infusion process, additional filler material further fills the gap or covers at least a portion of the at least one filler material. In addition, the method includes allowing the filler material(s) to cure. Thus, upon curing, the filler material(s) is configured to smoothly transition a load between the different materials of the blade components, thereby limiting an associated stress at the interface.
