Lifetime prediction of nozzle structures under streaming conditions (D03)

• Subject Area: Mechanics
• Term: from 2008 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 26293245

SP D3 develops simulation tools involving fluid-structure interaction (FSI), damage and failure for reliable lifetime predictions of rocket engine nozzle structures. Besides the modelling of typical rocket engines made of metallic alloys, nozzle structures made of the ceramic matrix composite material C/C-SiC are sub-ject of the investigations. The main task of the third funding period is the extension of the damage model for C/C-SiC including parameter identification. The FSI related research focuses on the further acceleration and the inclusion of new models into the FSI simulation environment. Finally, the developed simulation tools are validated on the basis of the sub-scale experiments of SP D9.
