THE HIGH-PRESSURE WIND TUNNEL (HDG) IN GÖTTINGEN IS A RESEARCH AND DEVELOPMENT FACILITY FOR AERODYNAMIC EXPERIMENTS. Type of wind tunnel Closed circuit, pressurized continuous low-speed wind tunnel with closed-wall test sections. Main features TEST SECTIONS Various test sections of 0.6 m x 0.6 mx 1 m (S = 0.36 m²) for special applications OPERATING RANGE Re0.1√(S) < 12 x 106 Ambient temperature 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 test 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)
