The cryogenic wind tunnel (KKK) in Köln is a cryogenic facility for research, development and data set measurements
Type of wind tunnel
Closed circuit, continuous, low-speed wind tunnel with a closed wall test section. Operation either at ambient temperature or cooled down by injection of liquid nitrogen.
Main features
Model support
- Sword with integrated roll support
- Half-model and surface vehicle support with under-floor balance
- Half-model support with tangential blowing at synchronized turntables
Auxiliary system
- Integrated optical traversing system
Typical tests
- 2D airfoil tests with high-lift and flow control devices (flaps, slats, vortex generators, trailing edge devices)
- Wind rotor blades
- Half-model tests of transport aircraft in high-lift configurations
- Surface vehicles (trains, trucks)
- Probe calibration, function and reliability tests
