INVESTIGATIONS OF AUTONOMOUS POWER SUPPLY SYSTEM OF THE SPACECRAFT PAYLOAD

摘要

It is demonstrated that for autonomous systems of the electric power supply of the spacecraft payload ,the main goal is to achieve the minimum possible weight and size of the entire power system with ensuring the required level of the reliability and service life. The basic principles of designing an autonomous electric power supply system based on a cryogenic turbogenerator are stated. Th e distinguishing features of a cryogenic turbogenerator with a hyperconducting inductor are described. A mathematical model of a hyperconducting turbogenerator, which underlies the optimum design algorithm,is proposed. The relationships between the unit power of the hyperconducting turbogenerator and the rotational speed and the relationships between the specific mass characteristics and the cryogenic turpbogenerator unit power have been obtained .Individual units of a cryogenic turbogenerator are described.
