WebSTOL airfoil built at WVU had a 4 ft chord and incorporated a drooped and blown leading edge. A low pressure blowing slot produced an air jet tangentially to the cylindrical flap hinge. The airfoil could be operated in the blown flap mode or as a CC airfoil after the 15% flap was folded fully forward and flush with the underside The wings and stabilizers of fixed-wing aircraft, as well as helicopter rotor blades, are built with airfoil-shaped cross sections. Airfoils are also found in propellers, fans, compressors and turbines. Sails are also airfoils, and the underwater surfaces of sailboats, such as the centerboard, rudder, and keel, are similar in cross-section and operate on the same principles as airfoils. Swimming and fl…
