The Super Sonic Wind tunnel is built in the connection of the Axial Compressor. The piping arrangements makes it possible to have a continuous flow of Ma number 2 in the test station of the wind tunnel.

The wind tunnel test section with super sonic flow is 140 * 140 mm.
The super sonic wind tunnel is currently the largest continuous one in Finland.
The flow reaches Mach number 2, which flow is pictured with numerical calculation results on the right

The wind tunnel can be used to measure turbine blade cascades or single profiles with supersonic velocities.
