Three wing sections FX66‐S‐196VI, E603 and AH82–150A were analyzed. Measured data of these wing sections are published. First wing section was measured in Stuttgart University and in Delft University of Technology, when other two wing sections were measured in Stuttgart University. These wing sections have different behavior in the region of maximum lift. FX66‐S‐196VI wing section has sharp drop in lift. The stall of the second and third wing sections is smooth, though different. All wing sections are affected by laminar separation bubbles. The calculations were performed using three codes: Eppler Program System, XFOIL and RFOIL. Eppler's code uses non‐interacted inviscid plus boundary layer method. Influence of separation is estimated using empirical correction in this method. XFOIL code of Mark Drela, MIT uses interacted zonal viscous/inviscid method. The wall transpiration model in this code approximates the displacement effect on the outer inviscid flow. RFOIL is a modification of XFOIL code for application in wind turbines performed at Delft University of Technology. The code's prediction of the airfoil performance around the two dimensional maximum lift was enhanced. The comparison of calculated and measured data is presented and analyzed. Santrauka Tyrimuose analizuotos profiliu FX 66‐S‐196 V1, E603 ir AH82–150A charakteristiku teorines reikšmes, apskaičiuotos XFOIL, RFOIL ir PROFIL05 programomis. Gautos teorines reikšmes palygintos su jau atliktu eksperimentiniu tyrinejimu rezultatais. Pirmas profilis buvo tyrinejamas Delft technologijos universitete (Olandija) ir Štutgarto universitete (Vokietija), like du ‐ Štutgarto universitete. Visi profiliai turi skirtingas maksimalios keliamosios jegos dalis. Profilio FX 66‐S‐196 V1 keliamoji jega mažeja staiga. Kitu profiliu keliamoji jega kinta tolygiai, tačiau skirtingai. Visu profiliu ucharakteristikas itakoja laminarinis atsiskyrimo burbulas.
