Aviation Design/ Tools (aeronautics - airfoils) » Complete Airfoil Archive

 Airfoil Archive: The most complete airfoil collection available. (approx 2000 airfoils) Includes Clark, NASA etc.
The airfoil profiles are in a lot of ways considered the heart of the aircraft. A good airfoil is critical in attaining the desired aircraft performance.

Aviation Design/ Tools (aeronautics - airfoils) » Professional wind tunnel

 Plans to construct your own professional wind tunnel. Designed by NASA Low cost project (can be built for less then US$ 250.00) This was designed to produce a steady airflow with no turbulence in the testing area. Designed to test scale model/s of your airfoil, fuselage, canopy etc.
