Transsonischer Windkanal Göttingen

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                             

Operating range

  • 0.3 < Ma < 2.2
  • 30 kPa < P < 150 kPa
  • Re0.1√(S) < 1.8 x 106
  • 293 K < T < 315 K


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
