Turbine test facility for aero engines and gas turbines
The Next-Generation Turbine test facility (NG-Turb) is used for aerothermo-dynamic investigations on high-efficiency high-, medium- or lowpressure turbines of aero engines, gas and steam turbines. The test facility (NG-Turb) allows the most important flow parameters at variable transonic Mach and realistic Reynolds numbers for load-flexible aircraft and power plant turbines. Depending on the application, single- or double-shaft turbine configurations can be installed, such as a combination of high- and low-pressure turbines. Furthermore, combustor simulators can be installed to investigate the combustor-turbine-interaction. To validate different cooling concepts, the cooling air supply can be adjusted for each of the ten feed lines. Typical turbine setups have several thousand measuring points to characterize the turbine flow. Pressure, temperature and multi-hole probes are recorded stationary and time-resolved. Furthermore, innovative optical measurement techniques such as Raman spectroscopy, particle image velocimetry or infrared can be applied.
