FIELD: propellant systems of flying vehicles working on liquefied gas. SUBSTANCE: cryogenic propellant is cooled in filling reservoir to temperature below minimum temperature of cryogenic propellant contained in tank to be filled in course of operation but not below solidification temperature of propellant free of admixtures, after which propellant is passed through filter at rating of 5 to 40 mk; temperature of propellant is raised as it flows over filling line. EFFECT: high purity of cryogenic propellant; reduction of accumulation of solidified gas admixtures in tanks. 3 cl, 2 dwg
