RESERVOIR FOR CRYOGENIC PROPELLANTS Russian patent published in 2006 - IPC B64D37/02 B64G1/40 

FIELD: propellant systems for aero-space craft, reservoirs for storage of cryogenic propellant (hydrogen, for example).

SUBSTANCE: proposed reservoir has hermetic protective casing, heat-insulated inner reservoir, filling, venting, pressurizing and propellant supply pipe lines and intake unit. Inner reservoir is secured to protective casing on two supports containing thin-walled bodies of revolution, taper in shape with heat-protective circular spacers and shield-vacuum heat insulation. One thin-walled body of revolution is connected with bush which is telescopically connected in its turn with cylinder attached to inner reservoir, thus ensuring relative motion of inner reservoir and protective casing. It is preferable that intake unit is provided with shut-off valves rigidly interconnected together and communicated with cavities near respective bottoms of inner reservoir by means of propellant intake pipe lines. These valves are controlled by means of electro-pneumatic system.

EFFECT: possibility of protracted storage of cryogenic propellant without venting when transport facility is at rest; continuous suction of propellant at alternating acceleration during motion.
