We developed software to model thermal conditions of an artificial Earth satellite (AES)
and find a solution to one of the three problems: determining the optimum emissivity and
absorptivity of a material; computing parameters of the total heat flow affecting the AES;
estimating the outer surface temperature of an AES for pre-computed external heat flows.
We obtained analytical equations of the thermal load on the AES at different orbital posi-
tions, plotted the curves for heat flows affecting the satellite shell and temperatures over
the AES shell cross-section depending on the AES orbital position. We created accurate
satellite models in the Blender 3D software to study heat flows and temperatures of com-
plex surfaces.
Keywords
