1. A rotor blade assembly of a wind turbine, the rotor blade assembly comprising:
a rotor blade comprising an aerodynamic body having an inboard region and an outboard region, the inboard and outboard regions defining a pressure side, a suction side, a leading edge, and a trailing edge, the inboard region comprising a blade root, the outboard region comprising a blade tip, the rotor blade defining a chord and a span;
the inboard region comprising a transitional region of the rotor blade that comprises a maximum chord,
wherein 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, and
wherein the unitless first derivative of the chord with respect to the span is greater than about −0.03 at an inflection point of the chord in the outboard region.
