Solar Dynamic Power for Space Station 841524

Power generation for the initial operational capability (IOC) of the NASA Space Station is expected to be in the range of 75-125 Kwe. Power growth from the 1992 IOC level is projected to reach 250-300 Kwe by 1997. The Space Station is to have an exceedingly long lifetime, a high reliability consistent with manned habitation, and be easy to maintain. Total life cycle cost and readily attainable schedules are key drivers in the program. The power generation system must likewise be compatible with these basic requirements. The Solar Dynamic Rankine Cycle is an approach whose state of technology readiness makes it an ideal candidate for power generation. Addressed are basic requirements, technology readiness, comparison to photovoltaic, and other dynamic power systems, cost effectiveness and interfacing with power management/distribution (PMAD).
