    ABSTRACT

    At the previous RHTG workshop, we reported a series of shock layer radiation measurements collected between 7-9 km/s and the corresponding disagreement to predicted radiance through the NEQAIR...

    During atmospheric entry high velocity free-stream gas decelerates rapidly through a shock near the vehicle surface. This sudden compression results in very high post-shock temperatures which are sufficient to cause thermochemical changes in the gas, including dissociation and ionisation. The internal energy modes of the flow also become excited, causing electromagnetic radiation to be...

    Introduction

    In previous years, spectrally and spatially resolved measurements of shock layer radiation in shocks composed of CO2 and mixtures (with N2/Ar) relevant to Martian and Venus entries have been reported [1]. Among other things, these measurements have been used to revise shock layer radiation models that are used for aeroheating predictions [2]. These updated models are now...

    Shock Tubes

    Detailed spectrally and spatially resolved radiance has been measured in the Electric Arc Shock Tube at NASA Ames Research Center for conditions relevant to Titan entry, with varying atmospheric composition, free-stream density (equivalently, altitude) and shock velocity. The test campaign measured radiation at velocities from 4.7 km/s to 8 km/s and free-stream pressures of 0.1, 0.28 and 0.47...
