The High Density Tunnel (HDT) is a reconfigured and upgraded facility from the original RAE shock tube, acquired by the University of Oxford in 2012. It operates either as a Ludwieg tunnel or a Light Piston Compression Heating facility, producing cold hypersonic flow conditions with test times long enough to investigate unsteady flow effects.
- Cold hypersonic flow facility for steady and unsteady aerothermodynamic testing
- Test durations up to 70 ms
- 6.5 m long, 152 mm diameter driver
- 17.4 m long, 152 mm diameter barrel
- Mach 3, 4, 5, 6, and 7 contoured nozzles
- Actuated traverse +/- 15 deg AoA. +/- 5 deg AoY
