Mathematical modeling of thermal conditions of non-hermetic spacecrafts
A description of the software complex for modeling the thermal conditions of non-hermetic spacecrafts in circular and elliptical orbits is given. The software complex structure, mathematical models of thermal processes in the presence of thermal control system are presented. For thermal processes calculation the method of lumped parameters is used. The results of thermal stabilization for model of orbital optical device are given. The software complex can be used in the design and development of thermal control systems of nonhermetic spacecraft, and in the determination of the causes of emergency situations in these systems in orbit as well.
