6 Egypt Silk Mill 2pi, wind turbine . Revisions 4B, 11 July 2011, panel 1 of 3 .

_

These figures provide a rotated view of a type of fillet which could join the wings' tips to the perimeter ring, making that union stronger .

As this fillet expands while maintaining an airfoil profile, it should offer added lift .

_

In the lowest images of the columns, (the first two columns of five total), the fillet's ringward end is to the viewer ;

airflow is from screen-top to bottom, and rotation is rightward .

In the highest images, the fillet's wingward end is toward the viewer, airflow is from screen-bottom to top and rotation (also) rightward .

( center column )

_

In this column, a (partially cut-away) section of the perimeter ring is shown, together with a fillet and a small section of wing .

This perimeter ring is also airfoil shaped, for reduced drag .

I expect the shape to create a slight acceleration of the air moving past the ring's widest point .

The fillet meets the ring there, hopefully with a slight boost to efficiency .

6 Egypt Silk Mill 2pi, wind turbine .

Revisions 4B, 11 July 2011, panel 3 of 3 .

_

These figures provide a rotated view of a type of fillet which could join the wings' tips to the perimeter ring, making that union stronger .

The rotation shown is complementary to that of panel one .

_

In these, (the last two columns of five total), the airflow is from screen-bottom to top .

The direction of rotation varies, from rightward in the top two figures, to leftward in the bottom two .

_

I hope that rotation speed will be slightly below 2pi times windspeed .
