description The invention belongs to the technical field of wind power generation, and particularly relates to a design method of a high lift-drag ratio wind turbine airfoil under a large attack angle, which is described by a forming process as follows: projecting a reference airfoil profile in an XY coordinate system to obtain a reference airfoil profile, and overlapping a leading edge point of the reference airfoil profile with a coordinate origin to obtain a reference airfoil profile; a slot is formed in the reference airfoil profile; selecting two points on the lower wing surface as the inlet of the slot, and recording as a point a and a point b; selecting two points on the upper wing surface as outlets of the slot, and recording the two points as a point c and a point d; a point e is selected between the point a and the point c, and a point f is selected between the point b and the point d; the aec and the bfd form a slotted shape, and a channel is formed in the middle of the airfoil; ae and bf are straight lines, e
