Abstract/Summary The nonequilibrium radiative heat transfer in low density, hypervelocity flows is investigated. The X2 facility at the University of Queensland was modified to allow experimentation at low pressures in nonreflected shock tube mode, characteristic of high altitude flight. Experiments were completed in a Titan mixture (98% N2, 2% CH4) at pressures of 13, 8, and 4 Pa and shock speeds of 6.4, 6.2, and 9.0 km/s respectively. Spectral measurements demonstrated a significant improvement in flow quality when compared to results from other facilities - producing test flow at such low densities, increasing the length of test gas available, and improving the signal-to-noise ratio of the spectral data.
