Abstract
Rotor blade assemblies for wind turbines are provided. In one embodiment, a rotor blade assembly includes a rotor blade having exterior surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge each extending between a tip and a root. The rotor blade further defines a span and a chord. A span-wise portion of the pressure side includes along a chord-wise cross-section a plurality of inflection points. The plurality of inflection points include a first inflection point and a second inflection point, the first and second inflections points positioned within approximately 50% of the chord from the leading edge.
