Abstract

A shear web foot for a wind turbine blade is described. The shear web foot extends longitudinally and comprises a base for attaching to an internal surface of the blade and first and second side walls. The side walls extend respectively from opposite longitudinal sides of the base. At least part of each side wall is inclined relative to the base and inclined towards the other side wall. A web-foot interior is defined at least in part by the base and the first and second side walls. One or more internal walls are located in the web-foot interior. The one or more internal walls extend between the base and the first and/or second side walls and are spaced apart from the first and second side walls to define a plurality of chambers within the web-foot interior.
