Section characteristics of a 10.5-percent-thick airfoil with area suction as affected by chordwise distribution of permeability

Robert E. Dannenberg, James A. Weiberg
Dec 1952

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.
