Wortmann FX 63-137 and Selig S1223 are high lift low Reynolds Number Airfoils which have widespread applications in heavy lift cargo planes and student projects like FSAE. The trailing edge is often given a radius for the ease of manufacturing and safety. This paper studies the variation in lift coefficients, drag coefficients and aerodynamic efficiency because of the amendments in the trailing edge radii of these two airfoils, ranging from 0.25% to 1.5% of the chord length.
