Wind Tunnel L2000
The L2000 is a closed-circuit Low-speed atmospheric wind tunnel and it was built in the 1960s in connection with the design of the SAAB Viggen fighter aircraft. In 1996, KTH took over the tunnel and significantly upgraded it and modernized it.
The tunnel has a 2m x 2m octagonal test section and can reach flow speeds up to 60m/s. The tunnel is equipped with a removable rig and acquisition system for aerodynamic loads measurement capable of continuous movement and acquisition in pitch and yaw for aircraft testing. The test section has the flexibility for installing instrumentation for non-standard testing.
The tunnel is extensively used for industrial work, research, and education in aeronautics in topics such as aircraft aerodynamics and aeroelasticity, as well as in naval architecture and marine systems for sail and ship aerodynamics.
Instrumentation:
- 6-degrees of freedom internal balance
- MicroDaq3 64 pressure acquisition system (+/-1psi range)
- Streamwise ProCap flow measurement system
- Fluorescent tuft flow visualization
- Smoke flow visualization machine
