The paper describes the loads acting on the rotor blades during engine operation, as well as the methods used to assess the strength of the impeller. An analysis of the results of static and modal calculations of a working blade with a disk of an axial compressor of a GTN-16 gas turbine plant in the domestic Fidesys CAE system by the finite element method is presented. Also, the calculation data were verified using the Ansys software package, as the most common system in the world for the numerical simulation of physical processes. Pictures of the stress-strain state of the blade with the disk are obtained. The zones of stress concentration in the model are identified and the safety factors of the blade and disk are determined. The six first frequencies of natural oscillations of the structure are found and the Campbell diagram is constructed. Possible options for improving the vibration reliability of the design of the considered axial compressor are outlined. A comparative analysis of the results of finite element modeling in the Fidesys and Ansys software systems was carried out.
