The high-pressure wind tunnel (HDG) in Göttingen is a research and development facility for aerodynamic experiments.

Type of wind tunnel

Closed circuit, continuous low-speed wind tunnel with closed-wall test sections.

Main features

Test sections

-

Six different test sections of 0.6 m x 0.6 m for special applications

Operating range

-

3.5 m/s < V < 3.5 m/s.

-

100 kPa < P < 10,000 kPa

-

Re_0.1√(S) < 12 x 10⁶

-

Ambient temperature

Model support

-

Remotely controlled sword for rear sting support

-

2D supports with integrated static and dynamic balances

-

Half-model support with integrated under-floor balances

Auxiliary systems

-

Permanently installed extension section in front of the test section for boundary layer and turbulence tailoring

-

Lock system for the entire test section.

Typical tests

-

Fundamental research of fluid dynamic phenomena and effects influenced by Reynolds number (spheres, cylinders, blunted or slender bodies, etc.)

-

Steady and unsteady loads on civil engineering and industrial structures (bridge segments, antennas, etc.)

-

Design studies and data set measurements of surface vehicles (trains, cars and trucks) at original Reynolds number

-

Multi-element trains with and without embankment, high sideslip angles.

-

2D airfoil tests (rotor blades)
