FIELD: engines and pumps.
SUBSTANCE: invention can be used in aerospace aircrafts. Proposed engine comprises nuclear reactor, heat exchange ducts to heat working medium pumped there through and nozzle attached to the reactor housing. Reactor housing has fissile region. Heat exchange chamber with radiation proof bottom is attached to reactor housing on the nozzle side. Rod-like heat-conducting elements pass, as sealed, through the bottom. One ends of aforesaid elements are located in reactor fissile zone, while the other ends are arranged in heat exchange chamber to make heat exchange channels to heat working medium pumped there through.
EFFECT: ruling out radioactive contamination of working medium and atmosphere.
