Abstract : The calculation results of a flow around a family of elliptic cones by a flow of ideal gas at large angles of attack were presented in previous reports. Subsequently, several variants of flow were calculated taking into account the real properties of air, which are in a state of thermodynamic equilibrium. These calculation results permit one to evaluate the effect of real gas properties, which proves to be insignificant for the variants of flow. The first part of this report is devoted to this problem. Calculated aerodynamic characteristics of elliptic cones over the angle of attack range from 30 degrees to 50 degrees in the case of an ideal gas are presented in the second part of this report.
