Scientific paper
Radiative gas dynamic model is presented, which is intended for study aerothermodynamics of space vehicles, entering planetary atmospheres, and for determination of trajectory parameters and some thermophysical properties of the planetary atmospheres by measuring spectrum of heat radiation from high-temperature gas around the space vehicle. This numerical simulation model is based on two-dimensional (axisymmetric) equations of nonequilibrium multi-component viscous and heat conducting gas dynamics, and on three-dimensional equation of radiation heat transfer. Distinguishing feature of the model is proper prediction of spectral directional emissivity of space vehicle during its braked descent in atmosphere.
