The paper considers one of the stages of atmospheric entry for aerospace craft. The aim is to investigate the influence of turbulence models on aircraft aerodynamics properties. To study the influence of a turbulence model on aircraft aerodynamic properties, the following models were chosen: k- Realizable, k- Shear Stress Transport and Transition Shear Stress Transport. The approach is to design a structured grid by means of ICEM CFD that allows solving a wide range of tasks, e.g. for supersonic flow. The paper investigates aircraft aerodynamic properties at an altitude of 11 km. The aerodynamics properties of aircraft were calculated for various turbulence models by means of a supercomputer Sergey Korolyov. Based on the results of the calculation, aircraft aerodynamic characteristics, the values of post-shock pressure and convergence for different turbulence models were estimated. To verify the design results the value of the post-shock pressure is compared with the pressure value obtained by engineering practice.
