RESUMO

The characteristics of the laminar–turbulent transition on the surface of a swept wing tested in the low-turbulence T-124 wind tunnel based at TsAGI are investigated. A comparison of the characteristics of the laminar–turbulent transition calculated using different turbulence models is carried out. A comparative analysis of the results of the calculations of the boundary layer parameters with the test data is carried out.
