LIQUID-PROPELLANT ROCKET POWER PLANT Russian patent published in 2000 - IPC

FIELD: space crafts; boost units, launch vehicle stages. SUBSTANCE: plant has tanks of oxidant and fuel with at least one cryogenic component, components feed turbopump sets, combustion with cooling jacket whose inner space is connected to fuel feed turbopump set, and supercharging gas storage cylinder. Moreover, turbocompressor set for circulating gas and cooler are introduced into plant. Supercharging gas storage cylinder is placed in communication with main lines delivering gas into turbopump sets delivering oxidant and fuel and into turbocompressor set providing circulation of gas. Outlet of sets communicate with cooler one outlet of which communicates with combustion chamber cooling jacket through compressor of turbocompressor providing circulation of gas. Outlet of jacket is connected with into main lines delivering gas into turbopump sets providing delivery of oxidant, fuel and turbocompressor set. Other outlet and inlet of cooler communicate with inner space of combustion chamber and with outlet of pump of turbopump set delivering oxidant. EFFECT: enhanced reliability and efficiency of plant, enlarged operating capabilities. 1 dwg
