Claims13
A method comprising:
- joining at least one integral bulkhead and a blade shell to form a blade;
- and then
- separating the blade into multiple blade segments such that each blade segment comprises a portion of the at least one integral bulkhead and a portion of the blade shell,
- wherein the at least one integral bulkhead includes a center flange, an inboard periphery flange extending from the center flange towards an inboard direction, and an outboard periphery flange extending from the center flange towards an outboard direction, and wherein separating the blade comprises separating along an axis of the center flange.
