The low-speed wind tunnel (LST) in Marknesse is an industrial wind tunnel for the low-speed domain
Type of wind tunnel
Continuous, atmospheric, low-speed wind tunnel with exchangeable test sections
Main Features
Test section
- 3.0 m x 2.25 m with turntables in top and bottom wall for 2D testing
- 3.0 m x 2.25 m with overhead balance for 3D testing
Model support
- Six-component overhead balance with wire suspension on strut for 3D models
- Sting support for models with internal balances
- Floor support for (half) models
Auxiliary systems
- Compressed air supply with a capacity of 5 kg/s continuously at 80 bar
- Remotely controlled y-z traversing system
- Vacuum system
- Ground board for simulation of ground effects
- Tangential blowing for test section boundary layer re-energizing
- Microphone wall array
Typical tests
- Two- and three-dimensional model testing
- Ground effect simulation
- Dynamic measurements like vibrations or unsteady pressures
- Turbofan propulsion simulators (TPS) and turbine air motors for propellers
- Engine simulation
- Propeller testing
- Acoustic measurements
- Environmental tests mainly on models of ships, trucks and building structures
- Air exhaust simulation with compressed air
- Air intake surveys
