![]() ![]() Where is NACA 4412 used? sports plane The NACA 4412 has been used in sports plane. The first digit expresses the camber in percent chord, the second digit gives the location of the maximum camber point in tenths of chord, and the last two digits gives the thickness in percent chord. National Advisory Committee on Aeronautics. National Advisory Committee for Aeronautics. where m is the maximum ordinate of the mean line expressed as a fraction of the chord and p is the chordwise location of the maximum ordinate. y c = m / (1 - p) 2 aft of the maximum ordinate. ![]() The camber line for a 4-digit airfoil is given by: y c = m (2 p x - x 2) / p 2 forward of the maximum ordinate, and. The definition of effective angle of attack will lead pure plunge case to an equivalent pure-pitch case, but the …Lift, drag, and pitching moment data for hundreds of such airfoil shapes was determined in wind tunnel tests by the National Advisory Committee for Aeronautics (NACA) and later by NASA, the National Aeronautics and Space Administration. Two digit mean lines 62 63 64 65 66 67 Three digit mean lines 210 220 230 240 250 Three digit reflex mean lines 211 221 231 Sarkar 26 investigated the effect of non-zero mean angle of attack on the wake of NACA 0012 airfoil at Re number of 10,000 during pure sinusoidally pitch and plunge oscillations using a particle-based Lagrangian viscous solver.
