Using the URANS approach, a numerical model has been developed on the basis of which a decrease in temperature separation and dynamic loading on the turbine stage blades is predicted by changing the position of the injectors at the outlet of the combustion chamber. A decrease in the value of temperature separation (a decrease of 7.2% according to the time-averaged Nusselt number) and dynamic loading (a decrease of 81.6%) on the blade surface is possible by adjusting the position of the nozzle center relative to the entrance to the inter-blade channel of the nozzle block. Keywords: rotor-stator interaction, unsteady heat transfer, temperature separation, clocking effect, dynamic loading.
