The T-ADFA shock tunnel is an Australian-developed experimental device capable of generating flows with up to 12 times the speed of sound at temperatures that can simulate Earth entry conditions and hypersonic air-breathing flight. This facility also has developed state-of-the-art laser-based methods to measure temperatures, gas composition and velocity in these extremely fast flow environments. The wide range of experimental measurements available from this device means it's one of the best-characterised hypersonic flow facilities in the world.
