The article considers the results of numerical simulation of unsteady gas-dynamic pro-
cesses accompanying start-up of perspective emergency rescue system propulsion. The
computation was performed for a number of specific points of the injection trajectory
using FloEFD package. It is shown that the maximum transient loads occur when firing
thruster of emergency rescue system on the starting point of the trajectory corresponding
to the conditions at the Earth's surface.
Keywords: propulsion system, unsteady jet flow, emergency rescue system, thruster duty
cycle; jet-shock interaction.
