The gas-dynamic characteristics of a supersonic flow in the analytical approximation of constancy of thermophysical properties during shock wave formation have been described in scientific literature. However, thermophysical properties’ deviations from the ideal model are observed during shock wave formation. This paper presents an engineering method for determining the gas-dynamic characteristics of a supersonic flow with a shock wave structure. The analysis includes assessing air parameters using the proposed engineering model and comparing them to analytical approximation calculations assuming thermophysical properties constancy. Numerical calculations using commercial software for simulating supersonic gas flow will verify the results.
