Regeneration induced variations of aeroelastic properties of turbine blades
Within subproject C4 of CRC 871 the influence of regeneration-related variations of turbine blades is investigated. These geometric variations have a direct effect on the aeroelastic excitation and the vibration behaviour. In the third funding period, the aim is to investigate the influence of disturbances from upstream-modules. For this purpose, the aeroelastic influences of thermal streaks on downstream turbine rows will be investigated. Furthermore, a probabilistic, automated process chain will be established with regard to real geometric variances and their influence on aeroelasticity, and a subsequent study will be carried out.
