The article presents the results of the computational investigation of supersonic flow around the rotation body with and without a flap. The work aims at studying the application of the numerical method developed on the basis of Reynolds-averaged Navier—Stokes equations (RANS-method) to solving the problem of flow around the rotation body with a flap as well as at choosing the most suitable turbulence model for such computations. Due to the calculations using various turbulence models and the software package ANSYS 14.5 we have obtained the pattern of flow and the distribution of pressure over the surface of rotation body both with the flap and without it and found the coefficients of net forces and moments acting upon it. We compare the pressure distribution in the detachable area in front of the flap as well as the summarized aerodynamic characteristics with the acquainted experimental findings. The study shows that to calculate the complicated separation-induced flows formed in the neighborhood of the body with a flap, the best convergence of numerical calculations results and experimental data is achieved when using the turbulence model SST k—ω in the calculations by means of RANS-method. The divergence between the numerical and experimental aerodynamic coefficients of the normal force and pitching moment does not exceed 5 %
