Aerodynamic root adapters for wind turbine rotor blades

A modified rotor blade assembly for a wind turbine, the modified rotor blade assembly comprising:

• a rotor blade having a pressure side, a suction side, a leading edge, and a trailing edge extending in a generally span-wise direction between a tip end and a root end;
• an aerodynamic root adapter attached to at least a portion of the root end of the rotor blade, the aerodynamic root adapter comprising:
• an interior support section having a first end that connects to the rotor blade and a second end that connects to a rotor hub of the wind turbine;
• and,
• an aerodynamic exterior section supported by the interior support section, wherein the aerodynamic exterior section extends an aerodynamic profile of the rotor blade beyond the root end of the rotor blade to at least partially between the root end of the rotor blade and the rotor hub.
