The basic results of space tests of liquid droplet cooler radiator models as the main elements of frameless systems for low grade heat rejection are considered. The studies carried out have been analyzed and intermediate elaboration’s results are summarized, which concern (1) the development of generators of drop let propellant flows, (2) revealing an operational behavior of fluid collectors of various types and analysis of unsolved problems associated with droplet collection upon the open trajectory’s section passage, and (3) pro vision of the coolant circulation contour’s closing. The necessity is substantiated for the activization of works directed to carrying out space experiments with improved radiator models and new promising propellants in order to provide a possibility of creating new space power plants characterized by megawatt power levels.
