Airfoil Coordinates (the format)
As depicted in the figure below, the coordinates listed in PROFOIL-WWW
output start at the upper-surface trailing edge at x =1 , y = 0 (1,0), go
around the top of the airfoil to the leading edge (0,0) and back to the
trailing edge (1,0). Airfoil coordinates through the leading-edge region
may not include the x=0, y=0 (0,0) point.
