Make a sketch in modeling with the chord and pitch circle. See attached PDF

I can tangent circle only at one end of the profile,I don't have tangency on other end.In your example profile is almost symmetric,since tangency point determines distance (radius) I need to make sure that my tangency point is at extreme end.How to find tangency point in this example?

Can you upload your wing profile?

See attached.  Make the tangent constraints to the bridge curves you used to create the profile.

 

You can only have one tangent constraint on a closed profile. If you did not have the bridge curve you could just extract curves and trim them so you have one curve at the LE and one at the TE.
