The invention discloses an aerofoil structure of a fixed-wing unmanned aerial vehicle. The aerofoil structure of a fixed-wing unmanned aerial vehicle comprises an aerofoil body. According to the invention, the upper surface of the aerofoil body is a convex surface curved upwards and the lower surface of the aerofoil body is a convex surface curved downward; the aerofoil body is formed by fixedly connecting a front aerofoil section located beside the wing root of the aerofoil body and a rear aerofoil section located beside the wing tail of the aerofoil body; vertical projection of the front aerofoil is rectangular while vertical projection of the rear aerofoil is trapezoidal; the angle range of a sweepback angle on a front edge of the rear aerofoil section is 7-10 degree and the angle range of a dihedral angle on the rear aerofoil section is 2-5 degrees. An unmanned aerial vehicle having the aerofoil structure of a fixed-wing unmanned aerial vehicle is characterized by being stable in flying and low in power consumption.
