The pressure on a NACA0012 and its modified aero-foils is measured in a circulating water channels. The so called Nakatake and Andou's SQCM method that comprises sources (S) on foil surfaces with Lan's quasi continuous vortex lattices on its camber plane is employed to analyze the surface pressure of the above foils. Viscous effect cannot be neglected as to the measured pressure on the two-dimensional aero-foils of 200mm chord under 1〜1.75m/s flow velocity (Rn≈2〜3.5×10^5). On the other hand the viscous effect is almost negligible except for tail ends as to the low aspect three dimensional foils of 500mm chord (Rn≥5×10^5) through which the availability of the SQCM analysis is discussed.
