The invention provides a special airfoil profile matching a high-universality large-load small unmanned aerial vehicle. The maximum relative thickness of the airfoil profile is 12.19% C, and the chordwise position corresponding to the maximum relative thickness is 27.1% C; the maximum camber is 5.3% C, the chordwise position of the maximum camber is 48.3% C, and the C is the chord length. The design Reynolds number of the airfoil profile is 3*10<5>-2*10<6>. The airfoil profile has the aerodynamic characteristics of high lift force and high lift-drag ratio (the maximum lift-drag ratio being greater than 100) and good engineering implementability in a design state, and can be applied to the design of a high-universality large-load small unmanned aerial vehicle, and the matched unmanned aerial vehicle has a relatively high lift-drag ratio under multiple speed working conditions.
