FIELD: power industry.
SUBSTANCE: in the first version of engine design output of intermediate fuel container is connected to input of fuel receiver and through pressure control valve to input of engine chamber cooling jacket while output of intermediate oxidiser container is connected to input of oxidiser receiver and through pressure control valve to input of injector head of engine chamber; besides inputs of intermediate container exchange-heaters through cut-off valves are connected to output of engine chamber cooling jacket and outputs of heat-exchangers are connected to input of fuel to injector head of engine chamber. In the second version cooling jacket of engine chamber is divided into fuel-cooled section and oxidiser-cooled section, at that outputs of intermediate fuel and oxidiser containers are connected to respective receivers of fuel components and through pressure control valves are connected to inputs of sections of chamber cooling jackets by fuel and oxidiser respectively; besides inputs of heat-exchangers for fuel and oxidiser intermediate containers through cut-off valves are connected to outputs of respective sections of engine chamber cooling while outputs of heat-exchangers for fuel and oxidiser intermediate containers are connected to respective inputs of these components to injector head of engine chamber.
EFFECT: invention provides higher reliability, simplicity of design, reduction of cost and power consumption and improved conditions for storage of cryogenic fuel components.
