摘要：
the paper is focused on possibilities of obtaining natural frequencies of jet engine iSTC-21v turbine blade using the CAD software's. First part of the article is devoted to the possibility of exact 3D turbine blade geometry CAD modeling and blade meshing, which is based on real turbine blade. The contribution highlights the possibilities of using ANSYS APDL and Creo Simulate for calculating the natural frequencies of high turbine blade. Another aim is to compare individual software based on final calculated values of turbine blade natural frequencies. The task is to evaluate the quality of the results in comparison to the required time for solution and creation of the mathematical finite element model in particular programs. The results in terms of natural frequencies are necessary for appropriate jet engine operation. Natural frequencies cannot be with excited frequency in operational range of jet engine. The results can be used to create Campbell diagram.
