Scramjet-powered access to space is expected to entail flight between Mach 10 and 15, along a dynamic pressure ascent trajectory of up to 100 kPa [1]. These flow conditions are characterised by total pressures of the order of gigapascals. Expansion tubes such as X2 and X3 at The University of Queensland (UQ), which add total enthalpy and total pressure to the test gas through an unsteady expansion, are the only current facilities which have the potential to achieve these very high total pressures.
