Numerical Modeling of ISS Thruster Plume Induced Contamination Environment
Abstract
Assessment of thruster induced contamination of critical surfaces is the important and necessary stage of International Space Station (ISS) component design. Plume contamination models aimed at the prediction of the spatial distribution of contaminant mass fluxes have been developed in the recent years for various ISS thrusters based on vacuum chamber and space flight experiments and empirical correlations 1, 2. Relatively scarce space flight contamination data have been gathered to date and are mostly limited to the measurements of thruster plume centerline contaminant fluxes. It is necessary, however, to have detailed knowledge of the contaminant deposition as a function of the angle from the plume centerline, especially, in the plume backflow region. The realization of this fact has motivated new flight experiments which are being planned for a future Space Shuttle mission.
