摘要： A horizontal axis wind turbine blade comprises a leading edge surface, a trailing edge surface, an upper camber surface extending between the leading edge surface and the trailing edge surface, and a lower camber surface extending between the leading edge surface and the trailing edge surface. Notably, the trailing edge surface includes a plurality of air flow mixing lobes. An ejector blade may be located above the upper camber surface and behind the trailing edge surface. The ejector blade may include an ejector blade trailing edge surface that includes a plurality of ejector blade mixing lobes. The ejector blade mixing lobes may include a plurality of ejector blade high energy mixing lobes and ejector blade low energy mixing lobes. Advantageously, the mixing lobes allow for a reduced wakes behind the HAWT and thus decrease the requisite separation distance between HAWTs in a wind farm.

摘要： A wind turbine has an impeller surrounded by a turbine shroud and/or an ejector shroud, wherein the turbine shroud and/or the ejector shroud include inflatable portions and/or flexible inflatable portions. In some embodiments, the turbine shroud and/or the ejector shroud include internal rib members whose shape or length can be changed to alter the characteristics of the wind turbine.
