METHOD OF OPERATION OF LIQUID-PROPELLANT ROCKET ENGINE AND LIQUID-PROPELLANT ROCKET ENGINE FOR REALIZATION OF THIS METHOD Russian patent published in 2002 - IPC

FIELD: liquid-propellant rocket engines. SUBSTANCE: proposed method of operation of liquid-propellant rocket engine consists in delivery of propellant components to combustion chamber of engine, gasifying one of components in combustion chamber cooling passage, delivery of it to turbine of turbo-pump unit followed by discharge to injector assembly of combustion chamber. Part of one of propellant components is directed to combustion chamber and remaining part is gasified and is directed to turbines of turbo-pump units. Gaseous component used in turbines is mixed with liquid component fed to engine under pressure exceeding pressure of saturated vapor of mixture being obtained. Liquid-propellant rocket engine has combustion with regenerative cooling passage, propellant component delivery pump and turbine. Engine is provided with pump of booster turbo-pump and mixer mounted in succession before component delivery pump of main turbo-pump unit. Outlet of pump of main turbo-pump unit is connected both with injector assembly of combustion chamber and with regenerative cooling passage of combustion chamber. Regenerative cooling passage is connected in its turn with turbines of main and booster turbo-pump units whose outlets are connected with mixer. EFFECT: enhanced reliability; improved power and mass characteristics of liquid-propellant rocket engine. 3 cl, 1 dwg
