Abstract—A conjugated problem statement for aerogasdynamics, internal heat and mass transfer and thermal strength of heat shield structures of hypersonic vehicles is formulated. A method for numerical solving of the problem is suggested. It is based on the iterative solution of the three types of detached problems: a gasdynamics problem for viscous heat-conducting flows, internal heat and mass transfer and thermoelasticity of shell constructions. An example of the numerical solution of the conjugated problem is given. It is shown that due to the high temperatures of the aerodynamic heating of the structure made of a polymer composite material there can appear a polymer phase thermodecomposition and intensive internal gas generation into the structure of the material.
