摘要： In one aspect, a rotor blade assembly for a wind turbine may generally include a rotor blade extending lengthwise between a root and a tip. The rotor blade may include a pressure side and a suction side extending between a leading edge and a trailing edge. Additionally, the rotor blade assembly may include a chord extender having an attachment portion coupled to at least of the pressure side or the suction side and an extension portion extending outwardly from the attachment portion beyond the trailing edge. The extension portion may extend chordwise between a first end disposed adjacent to the trailing edge and a second end disposed opposite the first end. The extension portion may include a surface defined between the first and second ends. The extension portion may further include at least one stiffening rib projecting outwardly from the surface.

摘要： A flow manipulating arrangement for a turbine exhaust diffuser includes a strut having a leading edge and a trailing edge, the strut disposed within the turbine exhaust diffuser. Also included is a plurality of rotatable guide vanes disposed in close proximity to the strut and configured to manipulate an exhaust flow, wherein the plurality of rotatable guide vanes is coaxially aligned and circumferentially arranged relative to each other. Further included is an actuator in operative communication with the plurality of rotatable guide vanes and configured to actuate an adjustment of the plurality of rotatable guide vanes. Yet further included is a circumferential ring operatively coupling the plurality of rotatable guide vanes, wherein the actuator is configured to directly actuate rotation of one of the rotatable guide vanes, and wherein the circumferential ring actuates rotation of the plurality of rotatable guide vanes upon rotational actuation by the actuator.
