Reflected shock tubes are used extensively to study a range of high enthalpy aerothermodynamic phenomena, typically associated with hypersonic flight. A reflected shock is utilised to produce a region of stagnated high-pressure gas which flows through a converging-diverging nozzle. The test time is defined by the duration of steady conditions in the stagnated supply region, typically on the order of 1-10ms. This necessitates a method for increasing the duration of steady supply conditions through a process known as contact interface tailoring. A tailoring method based on a state-to-state equilibrium thermochemistry solver is described which maintains the reflected shock strength across the driver and test gas. The method is applied to an Earth re-entry condition and validated through a shot conducted within the T6 Stalker Tunnel in RST mode.
