The paper discusses key operational features of the power supply system in reentry vehicles, including those of manned spacecraft. It identifies the reentry vehicle modes, which drive the requirements for the power supply system parameters. It provides an analysis of primary chemical current sources as compared with some secondary ones, taking into account their use in the power supply system of a manned re-entry vehicle. Reviewed in the process of selecting the energy storage unit was an octagonal list of key characteristics with visual geometric representation of the integral characteristic. Conditions were adopted for assigning weight factors and the integral indicator for selection of the storage unit. Good reasons for selecting the energy storage system based LiSOCl2 were demonstrated. Taking into account the requirements of high availability and safety of the system, an advanced hybrid power supply system is proposed which uses super-capacitor units.
Key words: power supply system, reentry vehicle, primary chemical current source, energy storage unit, super-capacitor, weight factor, hybrid energy storage system.
