The modular cooling water system at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in Cologne supplies the compressed air system for the high-pressure combustion chamber test rig at the DLR Institute of Propulsion Technology and the wind tunnels at the DLR Institute of Aerodynamics and Flow Technology.

Strong cooling for large-scale research

The system has a large working area. Thanks to two supply circuits with several pumps, all connected consumers can be supplied with sufficient energy, making it possible to operate test rigs and wind tunnels in parallel, even at higher energy loads. The cooling water system is designed to make partial load operation as efficient as possible while accommodating high peak loads, so it could support many additional test rigs and wind tunnels.

For internal and external partners in aeronautics and energy technology, the DLR Institutes of Propulsion Technology and Combustion Technology provide a unique testing infrastructure to study combustion chambers under realistic operating conditions regarding pressure and temperature across a range of performance classes.
