Abstract:
1. An apparatus for delivering a focused airstream flow from an area surrounding a wind turbine to rotor blades of the wind turbine, the apparatus comprising: an at least partially removable frame comprising sections with high strength supports covered in light weight air resistant materials, the sections when installed comprising a permanent section of at least one half the total frame size and a remaining removable section; the frame comprising angled portions and a flat portion connected together such that the angled portions extend from a proximal end at an installation grade level and connect to the flat portion at a distal end of said angled portion; the flat portion of the frame being substantially horizontal and parallel with the installation grade level and having a width at least the same measurement as the rotor blade arc diameter of a wind turbine, wherein a shortest distance from a connection edge between the angled portion distal end and the flat portion to the rotor blades is at least one half of the rotor blade arc diameter; the flat portion of the frame being continuous from the connection edge to an edge adjacent a support column of the wind turbine and the flat portion being substantially the same elevation as the connection edge so as to provide a substantially unimpeded airstream flow surface from along the angled portion to along the flat portion; the flat portion of the frame when connected to the angled portion having a height equivalent to the bottom tip of the rotor arc of the wind turbine less a minimal clearance amount to avoid impacting the flat portion of the apparatus frame by the rotor blade; wherein the apparatus is installed in an at least partially removable manner at least partially encircling the support column of the wind turbine so as to concentrate an airstream on the front bottom portion of the wind turbine rotor blades.
