The invention relates to the technical field of aircrafts, in particular to a flight test platform for a near space aircraft. The platform comprises an aircraft or an aircraft model, a three-degree-of-freedom platform, a hydraulic actuator cylinder, high-pressure water guns and a flexible pressure sensor array. The flexible pressure sensor array covers the surface of the aircraft or the aircraft model; the high-pressure water guns are distributed around the aircraft or the aircraft model, the three-degree-of-freedom platform and the hydraulic actuator cylinder are located in the aircraft or the aircraft model, the three-degree-of-freedom platform is used for controlling the swing angle of the three-degree-of-freedom platform according to an instruction of the flight control system, the hydraulic actuator cylinder is used for adjusting the swing center of the aircraft or the aircraft model, the high-pressure water gun is used for simulating resistance encountered by the aircraft or the aircraft model in the flight process, and the flexible pressure sensor array is used for measuring the surface pressure of the aircraft or the aircraft model. According to the invention, the working condition during actual flight can be simulated, so that the research and development and actual flight experiment cost is greatly saved.
