Rotor Blade Assembly Having Twist, Chord, and Thickness Distribution for Improved Performance

Abstract:

A rotor blade assembly of a wind turbine includes an aerodynamic body having an inboard region and an outboard region. The inboard and outboard regions define a pressure side, a suction side, a leading edge, and a trailing edge. The inboard region includes a blade root, whereas the outboard region includes a blade tip. The outboard region also has a twist variation of less than plus or minus about 0.5 degrees (.degree.) in order to reduce a rate of reduction in at least one of a chord length or a thickness of the rotor blade in the outboard region.
