Abstract
Feasibility of the Space Solar Power System (SSPS) is analyzed for an assumed 10MW model with an idealized generator/transmitter unified modules assembled to make a circular satellite with a diameter of 200m. Even under the operating conditions not advantageous for the heat management and under the use of FC-72 with very low latent heat of vaporization, it is possible to integrate heat transfer area required for keeping the weight fraction of vapor flow at 0.8 and preventing the occurrence of dryout before the radiators. Heat transfer in cold plates and heat transport by two-phase flow loops could be improved much more by using water or other organic fluids with a higher value of latent heat.
