The aim of this work is to explore the possibilities to find surge precursors from compressor vibro-acoustic analysis in a condition close to instability. For this purpose, a large campaign of data acquisition has been conducted by Thermochemical Power Group (TPG) of University of Genoa: T100 micro-turbine, equipped with three different volumes, has been sensorized with accelerometers and microphones and data acquired have been analysed with different methodologies in order to find surge precursors useful for the creation of an anti-surge control.
