    Abstract: In one aspect, a winglet for a rotor blade is disclosed. The winglet may generally include a winglet body extending at least partially between a winglet origin and a blade tip. The winglet body may define a sweep and a pre-bend. The sweep defined between the winglet origin and the blade tip may range from about 0.5% to about 4.0% of a span of the rotor blade. The pre-bend defined between the winglet origin and the blade tip may range from about 1.5% to about 4.5% of the span of the rotor blade.

    IPC: F03D1/06

    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 chord slope 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, a slope of a change in the chord in the outboard region at a peak from concave to convex or vice versa is greater than about −0.03

    Abstract: A wind turbine includes a hub configured to rotate about an axis at a first rotation speed and at least one blade coupled to the hub. The wind turbine also includes a sensor assembly configured to detect at least one characteristic of wind flowing through the wind turbine. The sensor assembly is mounted to the hub. The sensor assembly includes a laser device configured to emit a laser beam and at least one optical element configured to direct the laser beam. The sensor assembly also includes a non-motorized mechanism configured to rotate the at least one optical element at a second rotation speed when the hub rotates at the first rotation speed. The second rotation speed is greater than the first rotation speed.
