The method is based on the analysis of the stress-strain state of the free (power) turbine (FT) disk and its change during long-term operation in accordance with the characteristics of the operation of a ground-based gas turbine engines (GTE) for gas pumping aggregate (GPA). In addition, the paper examines statistical data on the mechanical characteristics and durability of the material disk of a FT — a heat-resistant nickel-based alloy EI698-VD. It takes into account the change in the characteristics of the material during the long-term operation of the ground-based GTE for GPA. The durability of the FT disk is predicted based on changes in statistical strength reserves during operation. The object of the study is the FT disk of the NK-16ST, which is currently widely used and has an established assigned resource of 150,000 hours.
