The invention discloses a preparation platform, particularly relates to a preparation platform of a high-speed wind tunnel model and a using method and a manufacturing method thereof, and belongs to the technical field of equipment used in the high-speed wind tunnel test preparation stage. The preparation platform comprises a platform rack, two supporting seats assembled on the platform rack, an outer shaft sleeve assembled between the two supporting seats in an up-and-down swinging manner, an inner shaft rod rotatably sleeved in the outer shaft sleeve, a model mounting joint arranged at the front end of the inner shaft rod, a first driving mechanism which is used for driving the outer shaft sleeve to swing between the two supporting seats, and a second driving mechanism which is used fordriving the inner shaft rod to rotate in the outer shaft sleeve. The platform is simple in structure, high in practicability and convenient to operate, and when the model to be subjected to the high-speed wind tunnel test is installed on the installation connector of the preparation platform, the attack angle and the rolling angle of the model can be adjusted according to needs through the first driving mechanism and the second driving mechanism of the preparation platform.
