Abstract

A rotor assembly for a wind turbine including at least one blade adapted to automatically adjust its shape as a function of rotational speed to create an efficient fluid dynamic profile over a wide range of wind conditions and rotational speeds. The rotor assembly includes at least one blade configured to respond to rotation induced forces to automatically bend in a manner to optimize its wind profile.
