FIELD: engines and pumps.
SUBSTANCE: proposed engine comprises first and second stages, inner and after shafts with blower fitted on inner shaft, and compressor fitted on outer shaft, high- and low-pressure turbines with cooling system, combustion chamber, heat exchanger and jet nozzle. Combustion chamber is arranged between compressor and high-pressure turbine. Heat exchanger is mounted ahead of combustion chamber. Note that additional compressor is arranged between high- and low-pressure turbines. Heat exchanger-heater is mounted right behind said additional compressor to communicate, via hear carrier pipelines, with nuclear reactor. Afterburner heat exchanger is arranged behind jet nozzle to communicate, also, with nuclear reactor.
EFFECT: higher thrust in afterburning, increased efficiency and reliability.
