This paper presents a comparison of two alternate versions of the passive thermal control system (PTCS) intended for the spacecraft's service module manufactured by Lavochkin Association (LA). In both cases the PTCS provides the required thermal mode of instrument compartment, formed on the base of eight thermal honeycombs panels (THP) with built-in heat pipes. Two different options of regulated removal of heat generated in the honeycomb panels have been analyzed: in the first case, with application of thermal louvers; in the second case, with use of radiators on the base of loop heat pipes (LHP). A qualitative comparison of the properties of the two proposed options has been done and their advantages and disadvantages were classified. With the help of a thermal mathematical model developed using the NX-Siemens software environment, the temperature characteristics of the alternative thermal control systems are compared. The recommendations to the application of the proposed technical solutions are made.
Keywords: passive thermal control system, the basic module of spacecraft, radiator on base of loop heat pipe, honeycomb panels with heat pipes, thermal mode, thermal mathematical model.
