Transonic and Supersonic
University of Cambridge
The Transonic and Supersonic Wind Tunnels at the University of Cambridge are two identical supersonic tunnels of test section 0.12 m x 0.2 m x 0.6 m and M number range 0.6 – 3.5. It boasts an internal 3-component sting balance and the latest in pressure, surface shear, Schlieren, shadowgraph, liquid crystals and PSP techniques, PIV and LDV.
