The Next Generation Turbine test bedis used for aerothermodynamic tests on highly efficient high-, medium- and low-pressure turbines of aircraft engines, gas and steam turbines.
The Next Generation Turbine (NG-Turb) test facility can be used to set key flow parameters at transonic Mach and realistic Reynolds numbers for research into load-flexible aero and power turbines. Depending on the application, single or twin-shaft turbine configurations can be installed, such as a combination of high and low pressure turbines.
In addition, combustor simulators can be used to analyse the interaction between combustor and turbine. To validate different cooling concepts, the supply can be adjusted through ten separate cooling air ducts. Typical turbine setups have several thousand measurement points to characterise the turbine flow. Measurement techniques such as pressure, temperature and multi-hole probes are used for both steady-state and time-resolved measurements. Innovative optical measurement techniques such as Raman spectroscopy, particle image velocimetry or infrared are also used.
