A mathematical model describing the heat and mass transfer processes occurring on the surface of a blunt body in flight in the atmosphere at hypersonic speeds. Medium is a mixture of reactive gases. The model is based on solving discrete analogs of the Navier-Stokes equations on an irregular grid 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. Relevance of the work due to the fact that one of the most important problems in the design of the SFA is a reliable prediction parameters of heat and mass transfer at the surface. The correct solution to this problem allows at the design stage to optimize the parameters of long-term staffing of the aircraft and determine the required thickness and materials as part of his warm protection.
