If you have modelled the airfoil, then just use line integrals (for lines) or force() for areas to get the forces acting on the foil. Why do you not have XYZ values...

As a line has zero area the force is zero. Extrude your polyline to make a surface, or take a cross section of your airfoil to do this.
