Abstract

The article is related to joint optimization problems for mass, power and reliability  characteristics of thermal control systems and cooled radio electronic equipment for long-term mission spacecraft with high reliability requirements. As equipment operational reliability depends maintly on cooling medium temperature it is interesting to choose some optimum temperature level at minimum mass and power characteristics under condition of required reliability. The suggested technique allows us to shoose optimum equipment redundancy level as well as optimum temperature level for thermal control systems at minimum values of mass and power characteristics.
