T1 - A Structural Health Monitoring (SHM) approach using a multidisciplinary digital twin for high-pressure turbine discs in civil aviation T2 - Proceedings IRF2020 : 7th International Conference Integrity-Reliability-Failur, Funchal/Portugal, 6-10 Sep 2020 N2 - The health status of an aircraft rotating turbine component depends heavily on the flight profiles flown by the operator. In contrast of this dependency, the declared Low Cycle Fatigue (LCF) life is typically determined for a designed flight profile, which is representative for most fleet flight profiles. A significant improvement in component utilisation without compromising safety can be achieved by using Engine Health Monitoring (EHM) data in order to monitor the LCF life by means of a digital engine twin. This paper is focussed on the development of a digital twin for a Civil Small and Medium Engine (CSME) and the structural health monitoring (SHM) of LCF life. The digital twin combines analytical models from multiple disciplines such as system performance, thermals and structures and aims to connect operational data to the component’s accumulated damage. This enables individual monitoring of the component’s health status, and prediction of Remaining Useful Life (RUL).
