What type of compressors are tested? Low Pressure Compressor RM 12 (GE F404) STARCS Proprietary
Why are compressors tested? • Measure the performance of a new design • Map the operational envelope • Establish the operational limits to avoid stall, surge and flutter • Verification of design models STARCS Proprietary
Main design criteria for the Compressor Research Facility • Drive power 4.3 MW • Rotation speed ranges: 0-5500 rpm and 0-25000 rpm, continuously variable • Variable inlet pressure • Variable outlet pressure • Air flow through the test facility without a test compressor installed • Efficient sound proofing of the control room and to the external environment. • Control system with safety monitoring and logging STARCS Proprietary

What is measured? • Inlet and outlet pressures and temperatures • Mass flow, rotational speed and drive shaft torque • Vibration and loads on the rotor blades using strain gauges or tip-timing • Vibration and loads on the stator vanes and the inlet guide vanes using strain gauges • Stall detection using temperature sensors and unsteady pressure transducers • Static pressures in the flow channel • For monitoring: Rotor tip clearance, shaft position, temperature and vibration of the compressor bearings, lubrication oil pressure, temperature and mass flow • Flow properties in the channel using traversing probes: pressure, temperature and flow angles
Summary • STARCS in-house designed and built Compressor Test Research Facility • Today a well proven concept • Drive power and mass flow capabilities in parity with customer demands • Unique capabilities with sub atmospheric outlet STARCS Proprietary
