High-pressure gas facility

The high-pressure gas facility at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Cologne site serves DLR's research institutes investigating gas turbine combustion chambers. This facility is the only energy technology test infrastructure of its kind in Europe.

Dedicated gases for power technology research

DLR's supply system consists of several storage facilities containing a variety of gases, including natural gas, hydrogen, carbon monoxide, butane, propane, ethane, carbon dioxide and nitrogen. These gases are available for the high-pressure combustion chamber test rigs at DLR Institute of Propulsion Technology. A high-pressure mixing facility can create a range of different gas mixtures, and the mixtures can be significantly altered during testing. Moreover, these gases or gas mixtures can be delivered pre-heated.

The Institute of Propulsion Technology's high-pressure combustion chamber test rigs and related supply systems support DLR Institute of Combustion Technology. For internal and external partners in the aeronautics and energy technology sectors, the result is a unique capability for researching combustion chambers under realistic operating conditions regarding pressure and temperature across a range of performance classes. The large-scale facility also has an external natural gas filling station.
