CurrentWhen re-entering the Earth’s atmosphere at high speeds, spacecraft encounter extreme temperatures and thermal loads which necessitate the use of an ablative heat shield to ensure the survival of the capsule. Due to the radical temperatures associated with re-entry the post-shock air itself will also begin to radiate, and at re-entry speeds above 11 km/s this radiation becomes the dominant source of heat transfer to the vehicle. This research is focused on studying the radiative heating experienced by a spacecraft re-entering the Earth’s atmosphere at speeds near 13 km/s originating from the vacuum-ultraviolet (VUV) spectral region, with a focus on understanding the coupling effects observed between radiation and ablative phenomena. This is accomplished experimentally using the University of Queensland’s super-orbital expansion tube facility X2.
