Facility Shallow Water Channel
Shallow Water Channel

Shallow Water Channel

The planar, compressibel gas flow around bodies or through nozzles can be modelled in shallow water for subsonic, near sonic and supersonic flows. In the Shallow Water Channel, certain phenomena in gas dynamics, such as Mach lines or shock waves, can be visualized descriptively and at low cost. This facility is exclusively used for graduate laboratories ...more

Small Boundary-Layer Wind Tunnel

The Institute has designed and constructed a 1:3 scale Small Boundary-Layer Wind Tunnel (Kleiner Grenzschichtwindkanal, KGWK) for student work.
The KGWK can also be equipped with different inlet obstacles and ground roughness to generate different velocity profiles and turbulence structures.

Inlet of the Boundar-Layer Wind Tunnel

Boundary-Layer Wind Tunnel

In the Boundary-Layer Wind Tunnel (Eiffel type with rectangular channel cross-section and closed measuring chamber; GWK) of the IAG, certain velocity profiles and turbulence structures can be generated by various combinations of inlet obstacles and ground roughness in order to simulate the turbulent boundary layer flow of the natural wind.

Facility Laboratory Wind Tunnel
Laboratory Wind Tunnel

Laboratory Wind Tunnel

Wind tunnel creating a free jet which is mainly used for teaching. Pressure distributions on wing profiles can be investigated in a vivid way here.
In addition, polar diagrams can be recorded with the aid of a 3-component strain gage scale.

Fan Test Bench
Fan Test Bench

Fan Test Bench

Leakage measurements can be carried out under defined laboratory conditions on the IAG's Fan Test Bench.

The volume flow is infinitely variable via a bypass device, the pressure in the test chamber is measured via inductive pressure transducers and the leakage volume flow can be measured via high-precision turbine gas meters.
