SEGMENTED ROTOR BLADE HAVING MAXIMIZED OVERALL PRE-BEND VIA AN INCREASED PRE-BEND IN A BLADE TIP SEGMENT THEREOF

摘要

A rotor blade for a wind turbine includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the first and second blade segments has at least one shell member defining an airfoil surface and an internal support structure. The first blade segment defines a first pre-bend in a flap-wise direction. The second blade segment defines a different, second pre-bend in the flap-wise direction. Further, the first pre-bend is greater than the second pre-bend. In addition, the first and second pre-bends provide an overall pre-bend in the flap-wise direction away from a tower of the wind turbine that allows for a predetermined deflection of the rotor blade towards the tower.
