Hello, thank you for you reply. 

Here you have a 2D sketch of the problem:

To better understand in 3D, the duct goes from an angular position of -60° degree to 60° while the stacking line of the blade profiles (red line in previous figure) is placed at an angular position equal to 0° (It is the NREL Phase VI blade).

If I did not make it clear let me know.
