Description
Summary:An analysis and design trade study was conducted to compare different solar dynamic power systems(SDPS) for space missions application. Closed Brayton Cycle(CBC), alkali-metal Rankine Cycle(RC), free-piston Stirling Cycle(SC) and cogeneration cycles were evaluated and also compared with each other. Conceptual designs were developed for cogeneration cycles of CBC combining with Organic RC or new two-phase power cycle, the Organic RC or two-phase power system recovers the waste heat from CBC to improve the system performance. The analysis and comparison of system performance utilized low earth orbit(LEO) 10 kWe power levels, including deployed area, efficiency, weight and cost. Using the conceptual design study as a basis, solar dynamic system would be a competitive power system for future space station and other space missions.
