Abstract

This report gives a short description of the closed circuit test facility available at Aachen Technical University in the Department of Jet Propulsion and Turbomachines.Using this test facility different geometrics of Supersonic/Transonic axial flow compressors with hub to tip ratio upto 0.5 would be tested. Freon-Air mixture(85:15 in concentration) was chosen as the working medium to avoid strength problems occuring at high speed.Freon regeneration unit which works online with the closed circuit is incorporated in the test facility.Supersonic and Subsonic five hole probes are used for measuring the detailed flow upstream and downstream of the rotor and stator.A modified Schlieren technique was developed to measure the unsteady flow downstream of the rotor and within the stator.The whole test data are evaluated by an electronic data processing system.
