Centrifugal compressor test rig

DLR Institute of Propulsion Technology

At the centrifugal compressor test rig, single fast-rotating high-loaded centrifugal compressors are investigated. In addition to measuring the compressor performance map, detailed flow field measurements are made in order to analyze the three dimensional flow field within the rotor and the diffuser by using conventional probes and several optical measuring methods like L2F, PIV and DGV. Only optical techniques are applicable within the rotating component.
