Abstract: In relation to an airfoil used for an ultralight airplane which cruises at low speed, the present invention relates to an airfoil for a ultralight airplane, which keeps aerodynamic performance of a main airfoil made of myler or plastic material by minimizing change in pressure which the main airfoil experiences through reducing curvature of a curved surface from a leading edge to the lower surface, and enhances convenience in manufacturing and structural strength by increasing thickness of a trailing edge.
