Test set-up at the Institute of Propulsion Technology
At the DLR Institute of Propulsion Technology, we use lasers to generate a so-called light section, also known as a transection. This makes individual planes in the focal area visible.

Multistage test bench for twin-shaft compressors
The Institute of Propulsion Technology operates a large multi-shaft compressor test rig in Cologne, which provides ideal conditions for analysing high-efficiency multi-shaft high-pressure compressor configurations.

Calming chamber
The Multistage Twin Shaft Axial Compressor Test Stand is available for experimental testing of axial machines. It allows the investigation of a single or multi-stage compressor. In addition, counter-rotating compressors and fans or low-pressure/high-pressure compressor combinations can be operated at different speeds.

Transonic Cascade Wind Tunnel
The test bed operates in a closed loop, allowing the Reynolds number to be varied independently of the Mach number. Total pressure and total temperature can be adjusted independently.

New combustion chambers for direct hydrogen combustion
In a joint measurement campaign, DLR and Rolls-Royce Germany have for the first time tested various hydrogen burners in a three-sector combustion chamber on the high-pressure combustion chamber test rig 1 at the DLR Institute of Propulsion Technology in Cologne under realistic operating conditions.
The Straight Cascade Tunnel
The large scale research facility is used for experimental investigations on flat turbine cascades with simplified flow and allows investigations over a very wide Mach number range. The facility is operated continuously in a closed loop with independent Mach and Reynolds number settings.

Multistage Two Shaft Compressor Test Facility
The compressor test rig at the DLR Institute of Propulsion Technology in Cologne enables a wide range of compressor analyses: Measurement of the complete compressor map, determination of the pumping limit, detailed flow field measurements and special applications such as active noise control on single-stage fans or counter-rotating propfans.

Radial compressor to validate new designs and numerical simulations
The Radial Compressor Test Bench is used for experimental testing of newly developed compressors. In addition to conventional measurement techniques, optical measurement methods and time-resolved sensors and measurement systems are used, which often have to be adapted to the extreme conditions.
