KPR - STARCS Turbomachinery Compressor Research Rig 

A turbomachinery compressor research facility is since 2006 in operation at STARCS. The facility is primarily used for research on gas turbine compressor components such as 1 to 3 stage compressors, but also for research on performance of inlet ducts as well as intermediate compressor ducts. The dedicated building houses an air intake, the test article, a drive system and an exhaust system. For testing at sub-atmospheric conditions an inlet valve is used to lower the inlet pressure and an ejector in the exhaust system allows for low loading of the test article. The data acquisition system is based on COTS PC's with National Instrument modular hardware for data acquisition and control. Data acquisition and reduction software are based on Labview and Matlab and can easily be adapted to test specific demands. Data can be presented and delivered in any customer specified format. Unsteady signals up to 100 kHz can be measured simultaneously and continuously.
Technical Specification
  • Maximum drive power: 4.3 MW
  • Maximum mass flow: 50 kg/s
  • Two gearboxes resulting in speed ranges 0-5500 rpm and 0-25000 rpm, continuously variable using a frequency converter
  • Inlet pressure control
  • Exhaust pressure control, 500 kPa gauge maximum
  • Maximum exhaust temperature: 260 °C.
  • Ejector augmentation in the exhaust makes it possible to run at low loading of the test article at sub-atmospheric conditions
  • Very effective noise reduction to the control room and to the environment
  • A state of the art control system with several safety features and data logging for later retrieval.
  • State of the art data acquisition system with:
  • 112 channels for dynamic data with up to 30 kHz bandwidth (100 kHz sampling rate) with simultaneous sampling on all channels.
  • 100 analogue data channels, up to 20 kHz sampling rate/channel with simultaneous sampling.
  • 200 static pressure ports
  • 64 thermocouple channels
  • All data channels recorded continuously during a test with simultaneous monitoring of all channels. All crucial data parameters e.g. bearing temperatures, vibration mode amplitudes (through on line FFTs) are monitored and checked if they exceed predetermined limits. If a limit is exceeded an alarm is shown and appropriate actions are taken.
Tests Performed
  • 2006-2007 HULDA, National programme for improved fan, 1 stage compressor
  • 2008 VITAL Booster, EU 6FP, 3 stage compressor. See Volvo Aero press release for further details.
