Comparison of Monte-Carlo Modeling and Experimental Results of UV-Emission from Engine Exhaust Plume Interacting with Upper Atmosphere

Abstract

Approximate method for Monte-Carlo modeling of interaction of high-altitude engine exhaust plume with atmosphere has been developed. The method was applied for analysis of recent experimental data on Russian spacecraft Soyuz plume glow. In particular, sensitivity of computed glow radiation to the choice of elastic collision cross-section of atmospheric oxygen with plume molecules and its reaction cross-section with water molecules in the plume is analyzed. Conclusions are made about these cross-sections values.
