A list of all the airfoils in the database in alphabetic order. In a wind tunnel or in flight an airfoil is simply a streamlined object inserted into a moving stream of air. To understand why a reflexed airfoil is able to provide longitudinal stability to a wing two things are important. Alternatively you can use the airfoil database search page to filter and order the airfoils by camber thickness and name. AeroFoil uses the vortex panel method and integral boundary layer equations to calculate drag lift and airfoil pitching moment at different angles of attack.
