Loehle, S. and Meindl, A. and Poloni, E. and Steer, J. and Sopek, T. and McGilvray, M. and Walpot, L. (2022) Experimental Simulation of Gas Giant Entry in the PWK1 Arcjet Facility including CH4. In: AIAA SciTech Forum 2022, 3 Jan - 7 Jan 2022, San Diego, California.


Abstract

An approach for the experimental simulation of entry conditions into the atmosphere of gas giant Neptune is presented. The PWK1 facility at the Institute of Space Systems of the University of Stuttgart has been modified in order to be used with hydrogen-helium mixtures. Additionally, methane was injected aiming at investigating the influence of methane on the radiation behavior. Methane could significantly change the radiative heating behavior during the entry flight. Based on first emission spectroscopic measurements, it is shown that methane influences the spectra behavior considerably. CH and C2 molecular radiation appear and the overall radiation level is higher. The prominent hydrogen Balmer series are saturating the spectrometer, which needs further attention in future measurements.
