Research at the Institute of Thermal Turbomachinery at the Karlsruhe Institute of Technology focuses on turbomachinery. This primarily includes aircraft engines and gas and steam turbines for energy conversion. Within the machines, the research work focuses on the "hot" parts of the machines. In addition to the combustion chamber and the high-pressure turbine, this also includes the secondary air and oil system. Hydraulic turbomachinery such as pumps and fans of various types are also the subject of current research. Accordingly, the institute is divided thematically into four working groups:
