Multiphysical systems, such a turbofan engines, require intensive analysis for the regeneration of individual modules to recover performance and ensure operational reliability. In subproject D6, the development of a dynamic digital twin is aimed at, for an exact modelling in the complete operational area. For this purpose, the IFAS research high-bypass jet engine is discretised and modelled in higher order. The aim of the project is to predict and evaluate the effects of deterioration and repair on safety limits and transient loads.
