Information model and software architecture for the implementation of the digital twin of the turbine rotor

Abstract

The manufacturing errors of the turbine rotor lead to the occurrence of vibrations that limit the acceptable modes of operation of aircraft engines. In order to reduce such vibrations, the current manufacturing technology of the rotor contains a complex procedure for balancing it. Creating a digital twin of the turbine rotor will allow to abandon the balancing procedure and reduce the cost of manufacturing parts. This paper presents such stages of creating a digital twin as the determination of typical errors in the manufacture of a turbine rotor, the construction of a digital twin of a part taking into account the errors in manufacture and the determination of its key characteristics. Analysis of the properties of the twin allows to optimize its parameters and to reduce vibration of the entire engine.
