LOX/LIQUID HYDROGEN ENGINE |
摘要 |
transport space systems. SUBSTANCE: engine has chamber with regenerative hydrogen cooling passage and self-contained turbo-pump units. Oxygen pump of one turbo-pump unit is provided with drive working in closed non-gas- generator scheme at afterburning. Hydrogen pump of other turbo-pump unit is provided with drive working in open gas-generator scheme on main components of propellant. Outlet cavity of turbine of oxygen turbo- pump unit is communicated with injector of turbo-pumped unit drive gas generator by means of gas line. EFFECT: increased specific thrust pulse of engine; reduced overall dimension of engine at constant degree of expansion of nozzle due to increased pressure in chamber obtained by increased pressure after pump of first turbo-pump unit. 2 dwg
