description The invention relates to a high-lift two-section airfoil profile suitable for general-purpose aircrafts and unmanned aerial vehicles, the airfoil profile achieves the optimal use aerodynamic efficiency when the lift coefficient is 1.6, the airfoil profile has slow stall performance, and the maximum use lift coefficient exceeds 2.0. The radius of the wing type leading edge of the main wing is 1.19% C, the maximum thickness is 13.80% C, the maximum thickness position is 36.32% C, the maximum camber is 6.12% C, and the maximum camber position is 82.28% C. The radius of the leading edge of the rudder surface is 0.32% C, the maximum thickness is 2.50% C, the maximum thickness position is 101.81% C, the maximum camber is 3.12% C, the maximum camber position is 79.58% C, the position of a rotating shaft is (0.86,-0.04), and C is the chord length of the basic airfoil before segmentation. According to the airfoil profile, the lift coefficient of the control surface is increased, meanwhile, the lift coefficient of the
