The paper presents an analysis of the influence on the performance of multi-spool axial turbines of aircraft engines of the factors that are traditionally not taken into account when calculating the characteristics using the three-dimensional numerical modeling as well as the mutual influence of spools on each other. By the example of a two-stage cooled turbine of an aircraft engine, the influence of these factors on the efficiency and throughput of the turbine spools was evaluated. An approach to the correction of characteristics to improve their accuracy when transferring them to the thermodynamic model of the engine was taken.
