Abstract
A rotor blade assembly of a wind turbine includes a rotor blade having an aerodynamic body with 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 rotor blade also defines a chord and a span. Further, the inboard region includes a transitional region of the rotor blade that includes a maximum chord. Moreover, a unitless first derivative of the chord with respect to the span of the rotor blade in the transitional region ranges from about −0.10 to about 0.10 from the maximum chord over about 15% of the span of the rotor blade. In addition, the unitless first derivative of the chord with respect to the span a slope of a change in the chord in is greater than about −0.03 at an inflection point of the chord in the outboard region.
