Approximating equations were derived to design optimal propellant insulation systems for transfer stages. Propellant, mission duration, thermal environment, insulating material, transfer stage design, and the orientation of the stage to the heat source were independent parameters for the computations. An optimized proportion of insulation mass and vaporized propellant mass was obtained. Maximum payload capacity was the optimizing criteria where the total mass and velocity requirement of the stage were given. (Author)
