The invention discloses an air floatation supporting device with a one-dimensional degree of freedom and an air seal. A model support, air floating shafts and air floating bearings are arranged in a sealing cover to form an air floating platform. The model support is erected between the pair of air floating shafts, the air floating shafts are supported by the air floating bearings, the air floating shafts are in sliding fit with the air floating bearings, and an aircraft model with one-dimensional freedom degree is arranged below the model support; and an outlet of the gas pressure source supplies gas to the air bearing and the sealing cover through the two precise pressure reducing valves respectively. The air floatation supporting device is installed on a long groove, and the long grooveis formed in an upper cover plate of a water tunnel or wind tunnel experiment section and is perpendicular to the incoming flow direction. The aircraft model penetrates through the long groove and isimmersed into the fluid;
