Abstract/Summary Atmospheric entry to the Gas Giants involves velocities of the order of 20 - 50 km/s, which is mostly beyond the capabilities of current ground testing facilities. This paper details an investigation exploring the operating limits of the X2 superorbital expansion tube at the University of Queensland (UQ), for the simulation of radiating gas giant entry flow conditions. Theoretical calculations show that the X2 expansion tube can simulate a proposed Uranus entry at 22.3 km/s but falls below the necessary 26.9 km/s velocity to simulate a proposed Saturn probe mission. Due to the current interest in sending atmospheric entry probes to Uranus and Saturn, this is a useful conclusion, demonstrating that there are experimental facilities capable of producing aerodynamic test flows for simulating gas giant entry conditions.
