Abstract

We present measurements of blunt body mid-wave infrared CO_2 radiation obtained in the Hypervelocity Expansion Tube at velocities between 3.1 and 3.4 km/s and freestream densities between 8 and 15 g/m^3 as well as shock tube measurements at velocities between 1 and 2 km/s and freestream densities between 70 and 1900 g/m^3. Point measurements of radiation collected using fiber optics embedded at the 0 and 16 degree angle of attack stagnation point of a scaled Mars Science Laboratory heat shield geometry are made. Spectrally resolved results over wavelengths of 4000-5300 nm are directly compared to numerical simulations using the NASA Langley LAURA CFD and HARA radiation codes.
