Description

THE TRANSONIC WIND TUNNEL (TWG) IN GÖTTINGEN IS A FACILITY FOR RESEARCH AND DEVELOPMENT TESTS IN THE TRANSONIC AND SUPERSONIC DOMAIN Type of wind tunnel Closed circuit, continuous, variable density sub-, trans- and supersonic wind tunnel with three exchangeable test sections MODEL SUPPORT Sword with integrated roll support Remotely controlled roll adapters Dynamic roll adapter Remotely controlled static and dynamic 2D/half-model supports AUXILIARY SYSTEMS Vacuum system Pressurized air supply Typical tests 2D airfoil tests with flow control devices (e.g. vortex generators, suction, blowing, ventilation, trailing edge devices, MEMs), helicopter blades Configuration studies, data set determination of 3D models (missiles, fighters, spacecraft). Air intake surveys for fighters and missiles Drag bookkeeping with through-flow ducts Dynamic tests: free and forced pitch oscillation of dynamically scaled flexible 2D and half-models; flutter and limit cycle oscillation; dynamically linked substructures (nacelle, flap); forced and free-to-roll maneuvers Air data system and probe calibration
