This paper considers the peculiarities of thermophysical processes at superorbital space vehicles entry into the Earth's atmosphere. The summary of the simplified CFD-model, taking into account the effect of local thermodynamic equilibrium (LTE) disturbance owing to depopulation of several excited atomic N and O states in emission processes in a shock layer is presented. Some experimental results obtained in the Arc-Driven Shock Tube (ADST) and argumentative the LTE disturbance effect impact are shown. These results are used for verification of the created CFD-model. Additionally, this model is verified by comparison of computations with flight measured data obtained in FIRE II Project. The carried out verification of the model shows a possibility of the presented CFD-model using for calculations of radiative and total heat fluxes at superorbital entry conditions.
