The purpose of the study was to develop and test a specialized software tool for calculating and optimizing labyrinth seals of gas turbine engines (GTE). In this work a comprehensive approach, integrating mathematical modeling, computational fluid dynamics (CFD) and parametric optimization algorithms, was applied. The materials and research methods include hydrodynamics and thermodynamics equations, adapted to describe the flow of working fluid through a system of channels of labyrinth seals. Turbulence effects, pressure differences, and temperature gradients were considered in the calculations. The ANSYS CFX software was used to verify the results. The results showed that even a slight change in geometric parameters (gap, tooth height, angle of expansion) leads to a significant change in flow characteristics. Increasing the tooth height from 3 to 7 mm reduces leakage of the working fluid by 12%, but requires the use of more complex technological solutions. The Genesis 1.3 program has demonstrated the possibility of effective seal optimization and integration with industrial CFD packages.
