Expansion tubes are an important type of test facility for the study of planetary entry flow-
fields, being the only type of impulse facility capable of simulating the aerothermodynamics …

Experiments were conducted using the X2 expansion tube at two conditions representative
of flight velocities of 10.0 and 12.2 km/s for a vehicle entry into Earth's atmosphere …

A robust fast-response calorimeter heat transfer gauge called the Diamond Heat Transfer
Gauge has been developed for use in transient hypersonic ground test facilities. Gauges …

Tuned free-piston driver operation involves configuring the driver to produce a relatively
steady blast of driver gas over the critical time scales of the experiment. For the purposes of …

The University of Oxford has embarked on developing the UKs fastest wind tunnel, T6, in
collaboration with the University of Queensland (Australia) using technology pioneered by …

Hypervelocity re-entry through the Earth's atmosphere surrounds an aeroshell with a
radiating shock layer, which has complex and potentially critical interactions with the thermal …

A superorbital reentry flow was realized in the X2 expansion tunnel of the Centre for
Hypersonics of the University of Queensland, resulting in measurements of electronic …

When entering a gas giant, the heat transfer to the surface of the entry vehicle is primarily
driven by radiation from the shock layer. It is not currently known how existing techniques …

Experiments were conducted in the X2 expansion tube to measure vacuum ultraviolet
radiation from shock layers representative of reentry conditions at flight equivalent velocities …

To provide data for the design of re-entry vehicles and validation of computational models,
ground testing facilities such as the Oxford T6 Stalker Tunnel are crucial. The current work …
