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
Main features
Test sections
- 1 m x 1 m with adaptive walls
- 1 m x 1 m with perforated walls
- 1 m x 1 m with flexible Laval nozzle
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. These tests are done in collaboration with the DLR Institute of Aeroelasticity. For more information please click here.
- Air data system and probe calibration
