Annular Test Facility Goettingen (RPG)

Institute for Aeroelasticity

The facility is designed to perform aeroelastic tests (flutter and forced response) of compressor and turbine blading. It was built according to plans of the Ecole Polytechnique Fédérale de Lausanne (LTT). Technical specification: · Test section for annular cascades for subsonic and transonic compressor and turbine blading · Diameter of the test section: 400 mm · Blade height: 40 mm · max.

Pressure Sensitive Paint (PSP)

Institute of Aerodynamics and Flow Technology

The PSP technique is an optical measurement method, which provides a pressure measurement on surfaces without introducing flow-disturbing probes and without affecting the surface of the model. To obtain the surface pressure by this method, the model is coated with a special paint, which is illuminated for example by UV light. The intensity of the resulting fluorescence light depends on the local oxygen concentration and allows for the determination of the two-dimensional pressure distribution.

System to measure unsteady signals (AMIS III)

Institute for Aeroelasticity

Facility is in service since 2008. It is used to measure voltage signals and to control test procedures (mobile operation world-wide possible). Ground based operation and in-flight operation possible (permission for DLR-ATRA A320).
