抄録（英）
A contact circular arc airfoil was shaped from two circular arc airfoils with different radius of curvature. We carried out two-dimensional numerical simlulation in order to clarify influences of maximum camber position on aerodymamc characteristics of the airfoil at Reymolds number of 40,000. The move of the maximum camber position brought about a change of flow field with vortices structure around the airfoll, and changes of the aerodynamic characteristics of the airfoil were observed with this flow field changing Maximum lift to drag ratio also show a maximum value when the maximum camber position has a near by 30% chord length of the airfoil.
