Reynolds number is one of the important simulation parameters in wind tunnel tests. Currently, a large number of tests increase gas medium density to increase the test Reynolds number. In the data obtained by this test technology, the Reynolds number is difficult to separate as it is coupled with the static aeroelastic effect of the model, bringing difficulties in data correction and application. To solve the coupling problem between the Reynolds number and the static aeroelastic deformation of the model in the Reynolds number effect wind tunnel test, this paper uses a combination of fluid numerical calculation and static aeroelastic coupling calculation to separately study the influence of the Reynolds number and static aeroelastic deformation on the model aerodynamic coefficient. Then a Reynolds number/static aeroelastic numerical separation technology is developed, which can effectively predict the influence of Reynolds number and static aeroelastic deformation on aerodynamic characteristics. Particularly, when the aerodynamic coefficient of the rigid model changes approximately linearly with the logarithm of the Reynolds number, a reasonable aerodynamic coefficient separation result is obtained.
