Abstract
This paper introduces the novel Rotating Turbine Rig (RTR) and the results of the first measurement campaign. The turbine test facility (NG-Turb) at DLR Göttingen is described, along with the setup of the RTR. A typical test day operation is outlined. The presented results focus on the aerodynamic design point of the 2½ stage high pressure turbine. The investigation of the in- and outflow homogeneity is included. The repeatability of the measurements on different test days is compared, demonstrating the consistency and reliability of the experimental data. The highresolution data is used to foster the understanding of multi-stage turbine flow
