hi my dear friends,

Wells turbine is the subject of the my Thesis:

Now Here,
I do not think the sweep tool is efficient(attention to below picture ).

I think that have the coordinates of the vertexes from the two airfoils(for blade),I can easily Create New model.

Do not know of a site that would provide the coordinates airfoils with different chord?

The following sites provides coordinates but I think cords are identical:
