Present and analyze the results of the simulation of processes of heat and mass transfer occurring on the surface of a sphere during the flight in the atmosphere at hypersonic speeds obtained using previously described methods. Solved discrete analogs of the Navier-Stokes equations on an irregular mesh of the calculated, together with the mass transfer equations for each component of the mixture, the basic differential equation for the thermal conductivity of the solid, the equation model to simulate the discrete ordinates radiative heat transfer. The results are compared with the data previously published works. Relevance of the work due to the fact that one of the most important problems in the design of the hypersonic aircraft is a reliable prediction parameters of heat and mass transfer on its surface. The correct solution to this problem allows at the design stage to optimize the parameters of hypersonic aircraft and determine the required thickness and materials of his warm protection.
