An investigation has been made at low speed of the two-dimensional aerodynamic characteristics of a 10.51-percent-thick symmetrical airfoil with area suction near the leading edge. The chordwise extent and distribution of porosity were adjusted for the purpose of obtaining a low quantity of suction-air flow for the maximum possible lift.
