Abstract

In this paper, the analysis of the existing methods for testing the turbine discs by imitation modeling is performed. The requirements for the geometry of the imitation model for gas turbine engine disc are determined. Variants of geometry and methods of loading for imitation models are proposed and investigated. The optimal method for modeling the critical stress concentration region in the area of the through hole in the disc hub is justified.
