High Speed Compressor Facility R-4

R-4The High Speed compressor facility R-4 is a closed loop system that allows testing of axial or radial compressors, from vacuum to 3 bar. For axial compressors, the maximum diameter must not exceed 480 mm and the available power is given by a 500 kW DC motor with continously variable speed.  The maximum shaft speed is 12000 RPM.  The loop is equipped with a diaphragm for accurate massflow measurements and a torquemeter to determine the shaft power.

The test section is currently housing an axial compressor stage with Inlet Guide Vanes, representative of a LP compressor designed for a contra-fan engine architecture.  The test section has been designed in a modular way in order to investigate the effect of different casing treatments on the stall margin.
