HiFire-1Post-Flight testing

Abstract

This project will look to undertake experiments in the short duration hypersonic wind tunnels in the Osney lab, to investigate the instability mechanisms that lead to boundary layer transition at different wall to gas temperature ratios and high AoA. In particular, the experiments will look to perform postflight testing of the Hi-FIRE 1 experiment, flown in 2010, matching all critical flow properties. The flight experiment suffered from higher than expected AoA, causing discrepancies with the pre-flight testing. The only post-flight testing at DLR measured different results than the flight, and is thought to be caused by differences in wall to gas temperature ratios. This research will provide greater insight into the mechanisms that led to boundary layer transition seen in the flight experiment.
