Flight assured.

German Aerospace Research Establishment

ASE FluiDyne formed a consortium with Interatom GmbH to supply a free piston shock tunnel to the German Aerospace Research Establishment at Gottingen, West Germany. ASE FluiDyne was responsible for the test leg. The resulting facility is able to produce the highest enthalpy in the world.

The tunnel is used to test air vehicle models at conditions simulating reentry into the atmosphere from an orbital flight at Mach 25. Air at pressures and temperatures as high as 30,000 psi and 21,000˚ F is expanded through a 35-inch-diameter, hypersonic nozzle and flows over the model for 1 to 2 milliseconds.

ASE FluiDyne collaborated with the German Aerosapce Center, DLR to design and supply the High Enthalpy Shock Tunnel Göttingen, HEG. It is one of the major European hypersonic wind tunnels and is unique in its ability to reproduce correct absolute re-entry speeds up 7 km/s ( flight Mach number of 25).
