Abstract
The results of experimental simulation in the vacuum chamber of processes of the International Space Station sur-face contamination by plumes of orientation thrusters are reported. Problems of modelling of orientation thruster plumes are considered, descriptions of experimental setup, methods, and results of measurements of angular distribution of a droplet phase with a co-current supersonic gas flow are given. It was shown that the mounting of the gas-dynamic protectors on the orientation thruster allows essential reduction of the droplet (contaminating) phase backflow.
