Boeing 737 wing model
This is a 1/4 scale model of a Boeing 737 wing. The full dimensions can be found at here (scroll to 'Wing Design'). Four different airfoils are used to construct this model - one each for the root and tip and two mid-span. The full wing span of a Boeing 737 (classic) is 28.8 m. On a real 737, the wings would be swept back at an angle of 25 degrees. The four airfoils used to construct this model are shown below.
