Abstract: The study considers the problem of calculating the shock-wave structures in calorically imperfect gas. An overview of calorically and thermally imperfect gas is provided. The dependence of adiabatic index on temperature for a diatomic gas is given. A comparison of this dependence with the linear approximation is performed. The concept of the effective adiabatic index at which the dynamic compatibility conditions have the same form as in the ideal gas is introduced. An algorithm for calculating the shock parameters using the effective adiabatic index is considered. The shock polars and shock reflections from the wall are calculated.
