ABSTRACT:
A structure and method for transferring load, particularly bending load, from a blade to a blade hub, such as for use in a wind turbine device, is provided. In one embodiment, the structure includes two or more spaced-apart annular rings, respectively contacting the inner surface of a blade root end, and the outer surface of a hub spindle, with a web extending therebetween.
