The invention discloses an airfoil profile two-freedom dynamic wind tunnel testing device which comprises a supporting frame. The supporting frame comprises a left supporting column and a right supporting column. The two supporting columns are respectively provided with an up-and-down motion module. Each up-and-down motion module is provided with a pitching motion module. Two ends of a tested airfoil profile are connected with one pitching motion module. When the pitching motion module performs simultaneous motion, the up-and-down motion module performs synchronous motion, thereby driving a tested model for realizing pitching and up-and-down coupling oscillation. The airfoil profile two-freedom dynamic wind tunnel testing device breaks through great technological problems such as statics and dynamics simulation optimization design of an airfoil profile oscillation device, safe synchronous control of a motor power system and pitching/up-and-down two-freedom motion path planning, and canrealize pitching and up-and-down motion, and rotor aerofoil profile low-speed dynamic aerodynamic characteristic testing capability in pitching and up-and-down coupling oscillation motion.
