„Integrated multidisciplinary design for hot structures”
The thermo-mechanical behaviour of spacecraft components under high loads could only be predicted insufficiently. Therefore, high safety factors must be considered at the design stage. The coupling of computational fluid dynamics (CFD) codes and structure tools enable a realistic capture of thermo-mechanical fluid-structure-interactions and can thus remarkably improve the effectiveness and reliability of a simulation.
The coupled simulation models developed in the IMENS project were successfully validated in experiments on two generic configurations (control surfaces, nose cap). In addition, the follow-on project IMENS+ addresses the current problem areas “active cooling“ and “time accurate coupled simulation“.
