Interdisciplinary Analysis of Transient Processes in the Electric Pump Unit of the Liquid Thermal Control System of the Spacecraft


The paper considers an electric pump unit of the spacecraft thermal control system. The aim of the work is to create a simulation model, which allows analyzing the distribution of temperature fields and the stress-strain state in the electric pump structure. The influence of structural materials on the transient behavior is also investigated for the changing the heat transfer agent temperature in the system.
