Abstract: A fluid transport system includes a housing defining a passageway for fluid to flow through the fluid transport system and a probe extending in the passageway. The probe includes a first end defining a plurality of sensing ports for the fluid to flow into the probe and a second end opposite the first end. The fluid flows through a plurality of conduits and a plurality of tubes. A differential pressure sensor is in fluid communication with the plurality of tubes such that the differential pressure sensor determines a differential pressure of the fluid in the plurality of tubes. A purge system is in fluid communication with the plurality of tubes. The purge system includes a source of purge liquid and is configured to direct the purge liquid through the plurality of tubes.

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

Abstract: A wind turbine is provided. The wind turbine includes at least one blade having a pressure side, a suction side, a leading edge, and a trailing edge that define an airfoil-shaped profile. The pressure side has a morphable region. The wind turbine also includes a control system configured to activate the morphable region to alter the airfoil-shaped profile and reduce negative lift generated by the blade when the blade is oriented at a negative lift angle.

Abstract: Rotor blade assemblies for wind turbines and methods for reducing rotor blade noise are disclosed. A rotor blade assembly includes a rotor blade having external surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a tip and a root. The rotor blade further defines a span and a chord. The rotor blade assembly further includes a tab. The tab includes an inner surface, an outer surface, a forward end and an aft end. The inner surface is mounted to one of the pressure side or the suction side. The outer surface has a cross-sectional profile configured to modify an operational value of the rotor blade at the trailing edge. The forward end is disposed within the chord.

Abstract: An apparatus for mitigating vortex-shedding vibrations or stall-induced vibrations on one or more rotor blades of a wind turbine during standstill includes at least one positioning element located between a blade tip section and a blade root section thereof. The positioning element is adapted for wrapping around at least a portion of the rotor blade. The apparatus also includes at least one airflow modifying element coupled to the positioning element and defining a height relative to a surface of the rotor blade. Additionally, the apparatus includes at least one securing element operably coupled to the positioning element for temporarily securing the airflow modifying element to the rotor blade.

Abstract: A method to reduce noise and vibration between separate blade segments of a jointed wind turbine rotor blade includes determining an actual offset at a chord-wise joint line between the shell members of the first and second blade segments at a load condition on the jointed wind turbine rotor blade, wherein the offset is any one or combination of a flap-wise offset, a twist-wise offset, or a yawl-wise offset. The method defines a modified configuration of the joint structure at a no-load condition on the wind turbine rotor blade that compensates at least partially for the actual offset at the load condition, and the first and second blade segments are connected with the modified configuration of the joint structure.

Abstract: A jointed wind turbine rotor blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint line. Each of the blade segments includes a pressure side shell member and a suction side shell member. A sealing tape is applied over the shell members so as to bridge across the chord-wise joint line. The sealing tape includes side edges that are aligned parallel with airflow over the shell members at the chord-wise joint line at a defined load and operational condition on the jointed wind turbine blade.
