Will solar dynamic power be used for the Space Station
The study focuses on solar dynamic power as a power source for the Space Station, with basic requirements being the 75-150-kW initial operational capability and provisions for the power system expansion from 250 to 300 kW, as well as a 28-day emergency power requirement. A comparison is made among the organic Rankine, closed Brayton, and kinematic Stirling systems, which exhibit low drag areas, weight, and cost, from the viewpoints of efficiency and life characteristics. The thermodynamic cycle and configuration of the organic Rankine system, which is noted to be ahead of other systems in the development stage, are detailed. Finally, consideration is given to the choice of working fluid and viable receiver storage materials.
