To achieve the highest possible efficiencies turbomachinery needs a thorough and accurate optimization that involves flow, thermodynamic cycle, vibrational and acoustical analysis. For this optimization precise test data is still required to calibrate the numerical tools.
With an area of more than 1000 square meters and a 3MW compressor station located in the basement, the institute's laboratory has the largest machine installation at the Technical University of Graz. The three compressors of this station can operate in 13 different configurations, thus providing air for a large variety of experiments and several test rigs.

A second compressor station (4 screw compressors) together with an air heater can deliver additional auxiliary air to the facilities in order to provide more engine realistic flow conditions in terms of temperature inhomogeneities as well as purge and cooling flows.
