In order to study the compressible flow field characteristics of heavy gas medium in high-speed wind tunnel and its related influencing factors, the real gas effect of heavy gas medium was considered, and based on one-dimensional isentropic flow theory, the flow field parameters for a specified set of free-stream Mach numbers under the given total pressure and total temperature were calculated under wind tunnel typical operating conditions. The calculation results showed that the gas compression factor
