Taking care of turbulence

Air intake chamber
Taking care of turbulence
What looks like a wind tunnel is actually an air intake chamber. Engine researchers use the 16-metre-long, eight metre- diameter enclosure to remove turbulence from air before it reaches the compressor of an engine during testing. This allows them to achieve optimal and repeatable conditions for their experiments. Fans and compressors are important research topics at the DLR Institute of Propulsion Technology by reason of the great influence they exert on the performance of engines and their noise emissions. The researchers are working on new designs for axial and radial compressors, and verifying their multidisciplinary development techniques using prototypes. The multi-shaft compressor test facility, shown in this image being prepared for a test, is essential for this process.
