Abstract :
A solar dynamic closed Brayton cycle system being developed for the Space Station Freedom is discussed. The aim of the work described here was to select a solar dynamic power module (SDPM) design and establish its behavior over the required range of operating conditions. The design point sizing and major considerations involved in the development of a mathematical computer model that predicts the behavior of the system based on different orbits are presented. Some of the orbital results for use in designing components are given. The overall results indicate that the SDPM design as operated satisfies the system requirements with achievable components and for moderate operating environments
