A symmetrical airfoil has another characteristic that Clarence used. Now you see where all the drag of a wire braced biplane comes from. In fact, a symmetrical airfoil has the same drag as a circular wire or pole 1/10 the thickness of the airfoil. Consider a finite wing using this airfoil, with AR 8and taper ratio 0.8. First (assuming the same thickness) a symmetrical airfoil has less drag than a flat bottom example. C l 0 at 0 angle of attack).considering the wind tunnel specification constraints, the aerofoil dimensions of chord C 30 cm (approximately 1/3 rd of the test section length to provide a uniform stream line air flow), maximum thickness of t 5. The measured lift slope for the NACA 23012 airfoil is 0.1080 degree1,and L0 1.3. For a symmetric aerofoil, no lift is generated at zero incidence (i.e. The release of this calculator does not and cannot warrant that any functions contained within are accurate or error free. Calculateand compare the lift slopes for (a) a straight wing, and (b) a swept wing,with a half-chord line sweep of 45 degrees.
