Testing and Measurement Techniques (TMV)

Rotor Testing (RPS)

The still to be developed 3 MW spin test facility will be used to test and validate new designs and material combinations for bladed rotors and integral blisks on a 1:1 scale. The spin test facility plays an important role to validate numerical methods regarding the dynamic response, which is essential to investigate the long-term behavior under realistic loads and temperatures. Over spin experiments provide important insights for the physical understanding of relevant failure mechanisms and the role of manufacturing procedures. Additional cyclic lifetime experiments will be used to further validate numerical methods.

Mechanical-Thermal-Chemical Testing (MTC)

The core part of the institute’s testing area is formed by several innovative test stands. They can reproduce realistic loads from thermal and mechanical stresses as well as corrosion not only separate but rather simultaneously. Thereby it is possible to conduct experiments under more realistic condition than it has been possible until today. Experiments will be conducted both static and dynamic to characterize innovative materials, like intermetallic compounds, fiber reinforced ceramics and additively manufactured materials, and investigate realistic use cases. All specimens can be evaluated using light microscopes or an Environmental Scanning Electron Microscope. Thereby it is possible to detect microstructural modifications, track damage mechanisms and gain results to validate simulations.
