The analysis of problems of laminar-turbulent transition in front of boundary layers, as well as large-scale effects in the study of laminar-turbulent transition in wind tunnels. Describes the methods and results of flight research Reynolds numbers began moving to the head of the flight of "cloud" in the presence of heat exchange and running engines of SRM. The results of calculations of aerodynamic heating and local coefficient of friction on the surface of the head of a missile ОФ-21. On the basis of flight research and calculations suggest the usefulness of theory of turbulent spots of Èmmon’s calculations of aerodynamic heating and friction resistance in the laminar-turbulent transition.
Keywords: aerodynamic resistance of friction, heat, the aerodynamic boundary layer, laminar-turbulent transition and turbulent stains of Emmon’s, the flight experiment, temperature of wall, boundary Reynolds number
