Title: Wind turbine rotor blades with load-transferring exterior panels

Patent ·
OSTI ID:1459660
; ;

Rotor blades for a wind turbines include a structural support member disposed internal the rotor blade that extends for at least a portion of a rotor blade span length and an airfoil structure supported by the structural support member, the airfoil structure comprising a shell portion and at least one load-transferring exterior panel. The shell portion and the at least one load-transferring exterior panel combine to form an aerodynamic profile comprising a leading edge opposite a trailing edge and a pressure side opposite a suction side. Moreover, the shell portion and the at least one load-transferring exterior panel are independently connected to the structural support member.
