The proper way to do this is to utilize a parametrized airfoil generator
function that returns you the airfoil data in list representation (i.e. a
representation you can visualize with polygon() ). 

In the next step you utilize a so called trajectory function that calls the
generator function with changing parameters and produces a series of
airfoils that defines your wing just - like a skeleton. Before it stuffs
these data into a list, it properly places each airfoil into 3D. To do this
you use affine functions that are the counterparts of translate() and
rotate() but operate over a series of 3D points. 

The final step is to skin or sweep the skeleton into a polyhedron.

principle.
