| Abstract: | A new type of multilayer thermal insulation structure used for cryogenic propellants tank was discussed.The structure was optimum configured according to the radiation heat transfer shield character of the layers along radial direction,mass of insulation material and structure intensity.The optimization consists of analyzing rhythm of multilayer insulations performance with variation of layer density,finding out optimized layer density in certain conditions and studying the relation between the optimized layer density distribution and the parameters of the insulation system. |
