Institute of Thermal Turbomachinery and Machine Dynamics

Welcome to the Institute of Thermal Turbomachinery and Machine Dynamics. The field of research covers many areas involving steam and gas turbines as well as machine dynamics. The current focus is mainly on the turbines, their efficiency, noise development, combustion and structural integrity. This page provides information about the institute, the capabilities, the courses offered and the actual research topics.

We hope you will find the information you are looking for. If not, please feel free to inquire by email or call us.

Wiki: Aeroengine Safety

Michael Landl provided a Wiki version of the famous textbooks on aeroengine safety by Axel Rossmann, who has been cooperating with our institute for many years. The textbooks cover a wide range of safety problems in aircraft and aeroengines and are in wide use in aeroengine industry.

Startup of a model gas turbine

http://carf-models.com

The video below shows the start-up of a JetCat P60-SE model gas turbine fired with kerosene at our institute. The turbine has an exhaust speed of 1418 km/h, a trust power output of 12.4 kW, a trust performance of 63 N and has a maximum revolution speed of 165,000 rpm.

The model is tested within the project Hy4Jetengine and will be fired also with methane and hydrogen. The setup, commissioning and start-up has been done by Dr. Johannes Peterleithner and Dipl.-Ing. Felix Greiffenhagen under the supervision of Prof. Jakob Woisetschläger.

Research Highlights

The Austrian Research Promotion Agency documented the results of two of our research projects within the Aeronautics Research and Technology Programme TAKE-OFF by video clips.

SEIKON3D dealt with the three-dimensional optimization of contoured side walls in jet engines, whereas LP-Inject worked on the efficiency improvement of axial turbo machines by passive flow injection.
