METHOD OF INJECTION OF PAYLOAD INTO SPACE AND MULTI-STAGE SPACE ROCKET SYSTEM FOR REALIZATION OF THIS METHOD Russian patent published in 1997 - IPC

FIELD: payload injections systems. SUBSTANCE: launch of multi-stage space rocket system and payload carrier module is effected at successive separation of stage used cryogenic components as propellant. Propellant reservoirs are filled with these components but for reservoir of last stage; in course of flight gaseous propellant is formed for last stage forced delivery of residues of liquid cryogenic components from the stage next to the last to propellant reservoirs of last stage and separate gasification of these components. Separable stages of multi-stage space rocket system but for the last stage are provided with reservoirs for liquid cryogenic components of propellant; last stage is provided with gas jet engine; high-pressure reservoirs to be filled with gaseous components of the same cryogenic propellant and high-lift detachable propellant lines which connect high-pressure reservoirs of last stage with reservoirs of liquid cryogenic components of propellant of stage next to the last are provided with liquid propellant gasifiers. EFFECT: enhanced efficiency. 3 cl, 6 dwg
