The Atmospheric Windtunnel Munich (AWM) is an Eiffel type design. The wind tunnel is open loop, i.e. the intake of the tunnel gathers air from outside and blows the air back outside from the outlet tower after passing it through a nozzle and test section.

The closed test section has a height-adjustable, flexible ceiling which is used to generate a specified pressure gradient (e.g. dp/dx = 0) along the flow direction. The test section with a length of L = 22.0 m is very suitable for the generation of fully developed thick boundary layers. The cross-section of the measuring section is approx. 4 m². The flow velocity in the test section is adjustable between 2 m/s and 40 m/s.
