The invention discloses a two-degree-of-freedom wind tunnel virtual flight test method. The two-degree-of-freedom wind tunnel virtual flight test method comprises the following steps: step 1, preparing a wind tunnel virtual flight test; 2, releasing the pitching degree of freedom and the rolling degree of freedom of the test model; 3, executing a pitching and rolling maneuvering flight control law; 4, ending single blowing of the wind tunnel virtual flight test; and 5, executing a wind tunnel virtual flight test in a new parameter state. According to the two-degree-of-freedom wind tunnel virtual flight test method, the advantages of real simulation of a flight physical environment, high efficiency, accuracy, low cost and repeatable simulation of a large wind tunnel are fully utilized, and the wind tunnel virtual flight test method suitable for integrated evaluation and verification of pneumatic/motion/control performance of an aircraft is established; the method is an innovative method means besides existing digital modeling simulation, semi-physical simulation and flight test methods, and has important technical support significance for flight control optimization design and performance evaluation of the aircraft.
