Abstract

Stress concentration zones near the GTE disk and blades junction are investigated numerically using various contact conditions. Aero-elastic effect of centrifugal and aerodynamic loads dependence on blade deformation is taken into account.

Keywords:

stress concentration, centrifugal loads, aerodynamic loads, disk and blades of compressor, finite element method.
