CRYOGENIC LIQUID AND TANK FOR STORING STORABLE FUEL

PROBLEM TO BE SOLVED: To provide a cryogenic liquid and a tank for storing storable fuel. SOLUTION: The separation of propulsion gas from liquid is performed by using filters and surface tension. Gas supply and takeout devices 4, 5 have rows of openings 6, 7, 8 and 9 arranged in an upper region of the tank 1 and on the peripheral side to expand toward the tank 1 side and covered with baffle plates. The openings 6, 7, 8 and 9 are provided with metallic sheets arranged alternately forward and backward. The openings 6, 7, 8 and 9 are jointed to the inside of housings of the gas supply and takeout devices 4, 5 via double filters, respectively. The inside of the housings, other metallic sheets are arranged to extend in parallel with longitudinal axes of the housings. Liquids entering into the gas supply and the takeout devices 4, 5 are stored in a storage tank at a ballistic trajectory stage until returned to the inside of the tank 1 at the next main propulsion stage.
