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.

Digital Twin Technologies for Turbomachinery in a Life Cycle Perspective: A Review

“…From the perspective of the life cycle, the most numerous phases are monitoring [30][31][32][34][35][36][37]47] and manufacturing [27,[39][40][41]45,51]. In addition, there is currently a certain amount of research in the prediction [14,25,26,44,46] and design [27,38,42] phases, and many scholars are also concerned about the operation and maintenance [29,43,51] phase.…”

“…Thus, in recent years, most of the research has been related to turbomachinery assets. There are some studies that have established a complete system or platform [26,30,[35][36][37][38]43,52]; however, more research has only proposed a framework or model of the DT [14,24,25,[27][28][29][31][32][33][34][39][40][41][42][44][45][46][47][48][49][50][51], and turning them into practical applications remains to be studied.
