Abstract/Summary Preliminary experiments representative of a Titan aerocapture peak heating conditions were conducted in the X2 expansion tunnel. A simulated Titan atmosphere test gas consisting of nitrogen and methane was accelerated to a speed of 6.5km/s. Measurements were conducted using emission spectroscopy and specially developed radiation gauges. Emission spectroscopy results successfully detected the main spectral contributors to the radiation in Titan entry, and the radiation gauges detected the radiative heat flux on the surface of the cylinder. Hence the ability of the radiation gauges to detect and measure the radiative heat flux in these conditions was demonstrated. A calibration procedure was developed, aiming to determine the amount of radiation detected pergauge in the UV band.
