The use of the finite element calculations to assess the impact of prolonged use on strength reliability of the turbine disk aviation engine

摘要

Based on the results of the calculation of the turbine disk by the finite element method and on the results of experimental tests of the disk samples from the heat-resistant deformable alloy under pulsing isothermal loading cycle, the effect of long-term operational life on the characteristics of the strength reliability of the disk is evaluated.
