The work is devoted to mathematical modeling of the thermal state of a blunt cone in a supersonic airflow conditions. A parametric study was conducted when simulating a flight at an altitude of H = 20 km at a speed equal to 4M. The thermal state of the cone is analyzed at various attack angles in the range from 0 to 10°. The distribution of characteristic heat transfer zones over the surface of the cone is investigated. Based on the simulation results, the corresponding base of calculation data is obtained. The results of the study can be used to optimize the geometric configuration and flight modes of high-speed aircraft.
