Abstract

A coupled 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 which 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 into constructions of hypersonic vehicles and thermoelasticity of shell constructions. An example of the numerical solution of the coupled problem of aerogasdynamics and thermal strength of elements of heat shield structures of an advanced vehicle 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.
