mechanical engineering; rocket engines. SUBSTANCE: liquid-propellant rocket engine has turbopump sets for delivery of fuel components, control and regulating sets, pipelines, heat exchanger, chamber with cooling duct whose inlet is connected with outlet of component cooler pump, and outlet is connected with chamber mixing head through heat-taking duct of heat exchanger and turbine of turbopump sets. Engine has generator whose mixing head is connected by pipelines through control and regulating sets with outlets of pumps of fuel components delivery turbopump sets, and fire space is connected with chamber mixing head and its fire space through heat-transfer duct of heat exchanger. Heat exchanger is installed outside the chamber. EFFECT: improved reliability of engine, reduced cost of operation. 1 dwg
