METHOD OF STORAGE OF LIQUID COMPONENT OF ROCKET PROPELLANT FOR SPACECRAFT ENGINE PLANT Russian patent published in 2004 - IPC

FIELD: rocketry and space engineering; protracted storage chemically unstable component of liquid rocket propellant in flight. SUBSTANCE: proposed method includes pouring the component into tank arranged inside spacecraft and thermostatting of tank containing liquid component. Thermostatting is effected at two different temperature ranges: at active sections of flight within (T_nom-ΔT_nom, T_nom+ΔT_nom), where T_nom is nominal temperature of delivery of component to engines; ΔT_nom is operational tolerance for nominal temperature and at passive sections of flight within (T_st-ΔT_st, T_st+ΔT_st),, where T_st is temperature of storage of propellant component; ΔT_st is operational temperature tolerance during storage at T_st+ΔT_st<T_nom-ΔT_nom. Besides that, lower boundary of temperature range during thermostatting propellant tank at passive sections of flight is equal to maximum melting point of propellant components in storage. EFFECT: increased storage period of liquid rocket propellant. 2 cl, 1 dwg
